Service AWD Warning Light — If Equipped
This telltale will turn on to indicate the
All Wheel Drive (AWD) system is not
functioning properly and that service is
required. Contact an authorized dealer.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
Warning System. Contact an authorized
dealer for service Úpage 187.
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 above, 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 telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale 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.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding 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.

CAUTION!
The TPMS has been optimized for the original
equipment 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. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

STARTING AND OPERATING111
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.
OVERLOADING
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not exceed
the GVWR and the front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and
ready for operation. Weigh it on a commercial scale
to ensure that it is not over the GVWR.
Figure out the weight on the front and rear of the
vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles. Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
LOADING
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side. Store
heavier items down low and be sure you distribute
their weight as evenly as possible. Stow all loose
items securely before driving. If weighing the
loaded vehicle shows that you have exceeded
either GAWR, but the total load is within the
specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
NOTE:Refer to the Vehicle Certification Label affixed to
the rear of the driver's door for your vehicle's GVWR
and GAWRs Ú
page 110.
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 warranty coverage, follow the
requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Manual Transmission — If Equipped
Trailer towing with this vehicle is not
recommended.
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 Ú
page 110.
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.
WARNING!
Because the front wheels steer the vehicle, 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.

114STARTING AND OPERATING
(Continued)
(Continued)
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your fascia/bumper or trailer hitch.

Weight Distribution
Consider the following items when computing the
weight on the rear axle of the vehicle:The tongue weight of the trailer.
The weight of any other type of cargo or equip
-
ment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on
your vehicle. Refer to the “Tire And Loading Infor -
mation” placard for the maximum combined
weight of occupants and cargo for your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side to
side which will cause loss of control of the
vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. Always, block or
"chock" the trailer wheels.
GCWR must not be exceeded.
WARNING!

21_LA_OM_EN_USC_t.book Page 114

STARTING AND OPERATING115
Perform the maintenance listed in the “Scheduled
Servicing” Ú page 246. When towing a trailer,
never exceed the GAWR or GCWR ratings.
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. For proper tire inflation procedures.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
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.
For further information Ú page 279.
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 actuated 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).
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
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!
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 accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
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.

118STARTING AND OPERATING
(Continued)
Replace tires when tread wear indicators first
become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid a
collision in a sudden stop.
Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not
eliminate, the amount of wheel slip across a given
axle for improved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
Flowing/Rising Water Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following
Warnings and Cautions before doing so.
WARNING!
Do not drive on or across a road or path where
water is flowing and/or rising (as in storm
run-off). Flowing water can wear away the road
or path's surface and cause your vehicle to sink
into deeper water. Furthermore, flowing and/or
rising water can carry your vehicle away swiftly.
Failure to follow this warning may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not exceed
5 mph (8 km/h) when driving through
standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which increases
stopping distances. Therefore, after driving
through standing water, drive slowly and
lightly press on the brake pedal several times
to dry the brakes.
Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
CAUTION!
Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom
of the tire rims mounted on the vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize
wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through
standing water. Do not continue to operate
the vehicle if any fluid appears contaminated,
as this may result in further damage. Such
damage is not covered by the New Vehicle
Limited Warranty.
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause
serious internal damage to the engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
CAUTION!
