Lumbar Support — If Equipped
This feature allows you to increase or decrease the
amount of lumbar support. The lumbar control
knob is located on the rear upper outboard side of
the driver's seatback. Rotate the control forward to
increase and rearward to decrease the desired
amount of lumbar support.
Suspension Seat — If Equipped
The seat is equipped with a mechanical spring
system and hydraulic shock absorber to ensure
maximum comfort and safety. The system of
springs also effectively absorbs impact from
uneven road surfaces. Damper Weight Adjustment
Use the weight adjustment knob, located on the
inboard side of the seat, to set the required setting
based on body weight, with settings between 88 lb
(40 kg) and 286 lb (130 kg).

Weight Adjustment Knob
Swivel Seat — If Equipped
The swivel seat lever is located at the lower front
inboard side of the seat. The seat may be turned
through 180° toward the seat on the opposite side
and approximately 35° toward the door. The seat
may be locked in the driving position or at the
180° position. To swivel the seat, pull the swivel
seat inboard lever outward, turn the seat to the
desired position and release the lever.
Swivel Seat Lever

If the vehicle is equipped with interlocking swivel
seats, the seats must be locked in the facing
forward position while driving. If the seats are not
in the correct position, a warning will appear in the
instrument cluster display.
If the driver or the passenger seats are not locked
in the facing forward position before the first
vehicle movement, shifting out of park is not
allowed until the seats are both locked in the
facing forward position. When the seats are not in
the right position and the first vehicle movement
after ignition START is attempted, a chime and a
message will appear in the instrument cluster
display. Rotate and lock the swivel seats in the
correct position before trying again.
Do not ride with the seatback reclined so that
the shoulder belt is no longer resting against
your chest. In a collision, you could slide under
the seat belt and be seriously or even fatally
injured. Use the recliner only when the vehicle
is parked.

82STARTING AND OPERATING
(Continued)
To Accelerate For Passing
While the Cruise Control system is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
button, or normal brake pressure while slowing the
vehicle will deactivate the Cruise Control without
erasing the set speed from memory.
Pushing the on/off button or placing the ignition
in the OFF position erases 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 if your vehicle is not equipped
with ACC Ú page 80.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (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 modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 256.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the conditions,
and you could lose control and have an accident.
Do not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. 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 condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).

110STARTING AND OPERATING
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 Gross
Axle Weight Rating (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.
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 Gross Vehicle Weight Rating (GVWR) and the
front and rear Gross Axle Weight Rating (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 axle 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 Gross Axle Weight Rating (GAWR), but the
total load is within the specified Gross Vehicle
Weight Rating (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.
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 Ú
page 109.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.

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 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 225.
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 may be required for
any trailer, for example trailers in excess of
2,000 lb (907 kg). Trailer brake requirements
vary by local law, consult local legal require -
ments where the trailer is to be towed for trailer
brake requirements.
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. For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL. Always, block
or "chock" the trailer wheels.

GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
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.

SAFETY139
ESC Operating Modes
The ESC OFF button is located in the
center switch bank, next to the hazard
flasher switch.
ESC On
This mode is the normal operating mode for ESC
equipped vehicles. Whenever the vehicle is
started, the ESC system will be in this mode.
This mode should be used for most driving
situations. ESC should only be turned off for
specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pushing the
ESC OFF button.
When in the “Partial Off” mode, the TCS portion of
ESC, except for the “limited slip” feature described
in the TCS section, has been disabled and the ESC
OFF Indicator Light will be illuminated. When in the
“Partial Off” mode, ESC will operate without engine
torque management. This mode is intended to be
used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESC would
normally allow is required to gain traction. To turn
ESC on again, momentarily push the ESC OFF
button. This will restore the normal “ESC On” mode
of operation.
NOTE:To improve the vehicle's traction when driving with
snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial
Off” mode by pushing the ESC OFF button. Once
the situation requiring ESC to be switched to the
“Partial Off” mode is overcome, turn ESC back
on by momentarily pushing the ESC OFF button.
This may be done while the vehicle is in motion.
WARNING!

Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent
accidents, including those resulting from exces -
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the
conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user’s safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC, except for the limited slip feature
described in the TCS section, has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

236SERVICING AND MAINTENANCE
NOTE:Wheel Valve Stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires

The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly
for wear and correct cold tire inflation pressures.
The manufacturer strongly recommends that you use
tires equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicators” in this section.
Refer to the Tire and Loading Information placard or the
Vehicle Certification Label for the size designation of
your tire. The Load Index and Speed Symbol for your tire
will be found on the original equipment tire sidewall.

See the Tire Sizing Chart example found in the Tire
Safety Information section of this manual for more
information relating to the Load Index and Speed
Symbol of a tire Úpage 226.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels. It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use all
season tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped

Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with Summer tires, be
aware these tires are not designed for Winter or cold
driving conditions. Install Winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C)
or if roads are covered with ice or snow. For more
information, contact an authorized dealer.

WARNING!

Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and
wheels may change suspension dimensions and
performance characteristics, resulting in changes
to steering, handling, and braking of your vehicle.
This can cause unpredictable handling and stress
to steering and suspension components. You
could lose control and have a collision resulting in
serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.

Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.
