Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the Four-Wheel Drive system. If the light
stays on or comes on during driving, it means
that the Four-Wheel Drive system is not
functioning properly and that service is required. We
recommend you drive to the nearest service center and
have the vehicle serviced immediately.
Service Forward Collision Warning (FCW)
Light — If Equipped
This telltale will turn on to indicate a fault in the
Forward Collision Warning System. Contact an
local authorized dealer for service
Úpage 154.
Service Stop / Start System Warning Light
This telltale will turn on to indicate the Stop/
Start system is not functioning properly and
service is required. Contact an authorized
dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control System is not functioning
properly and service is required. Contact an
authorized dealer.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed.
Should one or more tires be in the condition mentioned
previously, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
warning light when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
warning light illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
WARNING!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoid
-
ing sharp braking and steering. If a tire puncture occurs,
repair immediately using the dedicated tire repair kit and
contact an authorized dealer as soon as possible.

a fault detected with the Active Speed Limiter.
Forward Collision Warning (FCW) Off
Indicator Light — If Equipped
This light indicates that Forward Collision
Warning is off Úpage 154.
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD Low mode. The front and rear
driveshafts are mechanically locked together
forcing the front and rear wheels to rotate at
the same speed. Low range provides a greater gear
reduction ratio to provide increased torque at the wheels
Úpage 85.
Rear Axle Lock Indicator Light
This light indicates when the rear axle lock has
been activated.
Wait To Start Indicator Light — If Equipped
This indicator light will illuminate for
approximately two seconds when the ignition is
turned to the RUN position. Its duration may be
longer based on colder operating conditions.
Vehicle will not initiate start until telltale is no longer
displayed.
NOTE:The Wait To Start telltale may not illuminate if the intake
manifold temperature is warm enough.
Water In Fuel Indicator Light — If Equipped
The Water In Fuel Indicator Light will illuminate
when there is water detected in the fuel filter. If
this light remains on, DO NOT start the vehicle
before you drain the water from the fuel filter to
prevent engine damage, and please see an authorized
dealer.
GREEN INDICATOR LIGHTS

This light will turn on when the Active Speed
Limiter is on and set to a specific speed.
Adaptive Cruise Control (ACC) Set With
Target Vehicle Indicator Light —
If Equipped
This will display when the ACC is set and a
vehicle in front is detected Úpage 92.
CAUTION!
The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inopera -
ble. After using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an authorized
dealer to have your sensor function checked.
CAUTION!
The presence of water in the fuel system circuit may
cause severe damage to the injection system and
irregular engine operation. If the indicator light is
illuminated, contact an authorized dealer as soon as
possible to bleed the system. If the previously
mentioned indications come on immediately after
refuelling, water has probably been poured into the
tank: switch the engine off immediately and contact an
authorized dealer.

STARTING AND OPERATING85

The transmission will automatically downshift to FIRST or
SECOND gear (depending on model) when coming to a
stop. After a stop, the driver should manually upshift (+)
the transmission as the vehicle is accelerated.

 You can start out (from a stop) in FIRST or SECOND
gear. Starting out in SECOND gear can be helpful in
snow or icy conditions. Tap the gear selector forward or
rearward to select the desired gear after the vehicle is
brought to a stop.
 If a requested downshift would cause the engine to
overspeed, that shift will not occur.
 The system will ignore attempts to upshift at too low of
a vehicle speed.
 Avoid using Cruise Control when AutoStick is engaged
because the transmission will not shift automatically.
 Transmission shifting will be more noticeable when
AutoStick is enabled.
 The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, return the gear selector to
the DRIVE position. You can shift in or out of the AutoStick
position at any time without taking your foot off the
accelerator pedal.Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage until the trans -
mission fluid is warm (usually after 1 to 3 miles [2 to 5 km]
of driving). Because the engine speed is higher when the
torque converter clutch is not engaged, it may seem as if
the transmission is not shifting properly when cold. This is
normal. The torque converter clutch will function normally
once the transmission is sufficiently warm.
FOUR-WHEEL DRIVE OPERATION
1-SPEED FOUR-WHEEL DRIVE
(4WD) — IF EQUIPPED
This feature provides on-demand four-wheel drive (4WD).
The system is automatic with no driver inputs or additional
driving skills required. Under normal driving conditions,
the front wheels provide most of the traction. If the front
wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels. Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a preemptive effort to improve vehicle launch
and performance characteristics.
2-SPEED FOUR-WHEEL DRIVE
(4WD) — I
F EQUIPPED

2-Speed 4x4 Switch
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the power transfer unit.

86STARTING AND OPERATING

2-Speed 4x4 Switch (with Rear Lock)

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
4WD LOW
 REAR LOCK (If Equipped)
 N (NEUTRAL)
When additional traction is required, the 4WD LOW range
position can be used to provide an additional gear
reduction, which allows for increased torque to be
delivered to both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces only. Driving in
4WD LOW on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine, and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel. Any difference will adversely affect shifting and cause
damage to the driveline components.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
SHIFT POSITIONS
For additional information on the appropriate use of each
4WD system mode position, see the information below:
N (NEUTRAL)
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle
Úpage 120.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:For further information on the various positions and their
intended uses Úpage 88.
SHIFTING PROCEDURES
Shifting Into 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON/RUN position and the engine running,
shift the transmission into NEUTRAL (N), and push the
4WD LOW button once. The 4WD LOW indicator light in the
instrument cluster will begin to flash and remain on solid
when the shift is complete.

4WD LOW Button

NOTE:
If shift conditions/interlocks are not met, a message will
flash from the instrument cluster display with instructions
on how to complete the requested shift
Úpage 63.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the N
(NEUTRAL) position without first fully engaging the
parking brake. The N (NEUTRAL) position disengages
both the front and rear driveshafts from the powertrain
and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle,
unless the vehicle is otherwise secured (for example,
when attached to the tow vehicle).

23_KL_OM_EN_USC_t.book Page 86

92STARTING AND OPERATING
(Continued)
To Deactivate
A tap on the brake pedal, pushing the CANC button, or
normal brake pressure will deactivate the Cruise Control
system without erasing the set speed from memory.
The following conditions will also deactivate the Cruise
Control without erasing the set speed from memory:
Vehicle parking brake is applied
 Stability event occurs
 Gear selector is moved out of DRIVE
 Engine overspeed occurs
Pushing the on/off button or placing the ignition in the OFF
position, will erase the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. The Cruise
Control function performs differently
Úpage 90.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your Cruise Control. ACC utilizes a radar sensor
and a forward facing camera designed to detect a vehicle
directly ahead of you.
NOTE:
 If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead. 
Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected
Úpage 262.
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead and,
most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
 Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
 Will bring the vehicle to a complete stop and
hold the vehicle in the stop position for approxi -
mately three minutes when following a vehicle
ahead. If the vehicle ahead does not start
moving within three minutes, the parking brake
will be activated, and the ACC system will be
canceled.
 You should switch off the ACC system:
 When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa-
tions (i.e., in highway construction zones).
 When entering a turn lane or highway off-ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes.
 When towing a trailer up or down steep slopes.
 When circumstances do not allow safe driving at
a constant speed.

114STARTING AND OPERATING
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axle. Weighing
the vehicle may show that the GAWR of either the front or
rear axles has been exceeded but the total load is within
the specified GVWR. If so, weight must be shifted from
front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo, and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 113.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

23_KL_OM_EN_USC_t.book Page 114

STARTING AND OPERATING115
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables, and equipment (permanent or
temporary) loaded in or on the trailer in its “loaded and
ready for operation” condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. Refer to “Vehicle Loading”
Úpage 113 for
further information.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
The electronic TSC (if equipped) recognizes a swaying
trailer and automatically applies individual wheel brakes
and/or reduces engine power to attempt to eliminate the
trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are commonly used to tow small and medium
sized trailers.
Weight-Distributing Hitch
A weight-distributing hitch system works by applying
leverage through spring (load) bars. They are typically
used for heavier loads to distribute trailer tongue weight to
the tow vehicle's front axle and the trailer axle(s). When
used in accordance with the manufacturer's directions, it
provides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight-distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross Axle
Weight Rating (GAWR) requirements.
WARNING!
If the Gross Trailer Weight (GTW) is 3,500 lb (1,587 kg)
or more, it is mandatory to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
WARNING!
 An improperly adjusted weight-distributing hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
 Weight-distributing hitch systems may not be
compatible with surge brake couplers. Consult with
your hitch and trailer manufacturer or a reputable
Recreational Vehicle dealer for additional informa -
tion.

118STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer use.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 Refer to Tires for further information
Úpage 235.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
 An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
 Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
2,000 lb (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the vehicle
(or any other device plugged into vehicle’s electrical
connectors) before launching a boat into water.
 Be sure to reconnect once clear from water area.
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an acci -
dent.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an acci -
dent.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
