into four-wheel drive mode (if equipped), the traction control system will
be automatically disabled. Traction control operation will resume when
the vehicle is placed back into two-wheel drive mode.
WARNING:Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a Traction
Control™ event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
The Traction Control™ switch,
located on the instrument panel to
the left of the climate control
system, has an indicator light that
illuminates when the system is off.
The Traction Control™ system will
automatically turn on every time the
ignition is turned off and on. The
Traction Control™ system should normally be left on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Control™ system off. This may allow
excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver.
If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
•Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.

WARNING:Vehicles with a higher center of gravity such as
utility vehicles and trucks handle differently than vehicles with a
lower center of gravity. Utility vehicles and trucks arenotdesigned for
cornering at speeds as high as passenger cars any more than low-slung
sports cars are designed to perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in
these vehicles. Failure to drive cautiously could result in an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death.
WARNING:Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Do not overload
your vehicle and use extra precautions, such as driving at slower
speeds, avoiding abrupt steering changes and allowing for increased
stopping distance, when driving a heavily loaded vehicle. Over-loading
or loading the vehicle improperly can deteriorate handling capability
and contribute to loss of vehicle control and vehicle rollover.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the 3 (on) position and the brake pedal is not depressed.
If you cannot move the gearshift lever out of the P (Park) position with
the ignition in the 3 (ON) position and the brake pedal depressed:
1. Apply the parking brake. Turn the
ignition key to 1 (off), then remove
the key. Locate the access cover
plate for the brake-shift interlock
override. It is located on top of the
steering column shroud.

2. Apply the brake. Use a tool (or a
small screwdriver) to pry out the
access cover. Insert the tool into the
access hole and slide the white
override button towards the left.
Move the gear shift lever into N
(Neutral) while holding the white
override disc towards the left.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
Emergencieschapter.
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer as soon as possible.

Understanding the shift positions of the 5–speed automatic
transmission
This vehicle is equipped with an adaptive Transmission Shift Strategy.
Adaptive Shift Strategy offers the optimal transmission operation and
shift quality. When the vehicle’s battery has been disconnected for any
type of service or repair, the transmission will need to relearn the normal
shift strategy parameters, much like having to reset your radio stations
when your vehicle battery has been disconnected. The Adaptive
Transmission Strategy allows the transmission to relearn these operating
parameters. This learning process could take several transmission
upshifts and downshifts; during this learning process, slightly firmer
shifts may occur. After this learning process, normal shift feel and shift
scheduling will resume.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
•Start the engine
•Depress the brake pedal
•Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.

Parking your vehicle
1. Apply the brake and shift into the neutral position.
2. Fully apply the parking brake, then shift into 1 (First).
3. Turn the ignition off.
WARNING:Do not park your vehicle in Neutral, it may move
unexpectedly and injure someone. Use 1 (First) gear and set the
parking brake fully.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in reverse and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.

The RSS detects obstacles up to
6 feet (2 meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
The RSS may have reduced
performance or an increased chance
of false detection if the tailgate is
not locked and in the upright position. If the tailgate is down, the RSS
tone may be heard intermittently or continuously. The tone may also be
heard if items in the truck bed protrude rearward outside the bed.
The RSS automatically turns on
when the gearshift lever is placed in
R (Reverse) and the ignition is on.
An RSS control allows the driver to
turn the RSS on and off. To turn the
RSS off, the ignition must be on,
and the gear selector in R
(Reverse). An indicator light on the
control will illuminate when the system is turned off. If the indicator
light illuminates when the RSS is not turned off, it may indicate a failure
in the RSS. The RSS will remain off until either the RSS control is
pushed again or the ignition switch is recycled.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
