9-16 Driving and Operating
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
OFF. On vehicles with an
automatic transmission, the shift
lever must be in P (Park) to turn
the ignition to the OFF position. 4. Set the parking brake. See
Electric Parking Brake on
page 9‑26.
{WARNING
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold the engine START/
STOP button for longer than
two seconds, or press twice in
five seconds.
ACC/ACCESSORY (Amber
Indicator Light): This mode allows
the use of some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY. The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.
ON/RUN/START (Green Indicator
Light):
This mode is for driving and
starting. With the ignition off, and
the brake pedal applied, pressing
the button once will place the
ignition system in ON/RUN/START.
Once engine cranking begins,
release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine on
page 9‑17. The ignition will then
remain in ON/RUN.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off, and
the brake pedal not applied,
pressing and holding the button for
more than five seconds will place
the vehicle in Service Only Mode.

Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑22. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two‐second
window. It will not activate if the
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a TCS that limits
wheel spin. This is especially useful
in slippery road conditions. The
system operates if it senses that
one or both of the front wheels are
spinning or beginning to lose
traction. On an All-Wheel-Drive
(AWD) vehicle, the system will
operate if it senses that any of the
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces engine
power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.The TCS/StabiliTrak light flashes
when the traction control system is
limiting wheel spin.
The TCS/StabiliTrak light comes on
and the appropriate message will be
displayed in the DIC if there is a
problem with the traction control
system. When the TCS/StabiliTrak
light is on, the system will not limit
wheel spin. Adjust your driving
accordingly. SeeTraction Control
System (TCS)/StabiliTrak
®Light on
page 5‑24.
TCS automatically comes on
whenever the vehicle is started. To
limit wheel spin, especially in
slippery road conditions, the system
should always be left on, but it may
be necessary to turn the system off
if the vehicle is stuck in sand, mud,
or snow and rocking the vehicle is

required. SeeIf the Vehicle Is Stuck
on page 9‑9. See Winter Driving on
page 9‑7 for information on using
TCS when driving in snowy or icy
conditions.
The TCS/StabiliTrak button is
located on the center stack.
Press and release the TCS/
StabiliTrak button; the traction
control system will turn off and the
appropriate message will be
displayed in the DIC. Press the
button again to turn the system back on. For information on turning
StabiliTrak off and on, see
StabiliTrak
®System on page 9‑29.
Adding non-dealer accessories can
affect your vehicle's performance.
See Accessories and Modifications
on page 10‑3.
StabiliTrak®System
The vehicle has an electronic
stability control system called
StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the
system senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the direction which
you are steering.
When the system activates, this
warning light flashes on the
instrument panel. A noise may be
heard or a vibration may be felt in
the brake pedal. This is normal.
Continue to steer the vehicle in the
intended direction.
If there is a problem detected with
StabiliTrak, the appropriate
message displays on the Driver
Information Center (DIC) and the
TCS/StabiliTrak warning light comes
on in the instrument panel cluster.
When this message and light
display, the system is not
operational. Driving should be
adjusted accordingly. See Driver
Information Center (DIC) on
page 5‑27 andTraction Control

Automatic Level Control
The automatic level control rear
suspension is available on some
vehicles.
This type of level control is fully
automatic and will provide a better
leveled riding position as well as
better handling under a variety of
passenger and loading conditions.
An air compressor connected to the
rear shocks will raise or lower the
rear of the vehicle to maintain
proper vehicle height. The system is
activated when the engine is
running and will automatically adjust
vehicle height thereafter. The
system may exhaust (lower vehicle
height) for up to 10 minutes after the
engine has been turned off. You
may hear the air compressor
operating when the height is being
adjusted; this is normal.
If the compressor runs often for
longer than one minute within the
same trip and the vehicle remains
low in the rear, see your dealer for
service.If the vehicle is not used for several
weeks, the rear of the vehicle may
look low. When the engine is
started, the vehicle will return to the
proper height.
If a weight-distributing hitch is being
used, it is recommended to allow
the shocks to inflate, thereby
leveling the vehicle prior to adjusting
the hitch.
Cruise Control
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise
control disengages.

Adaptive Cruise Control
For vehicles with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the distance
between your vehicle and a
vehicle-detected directly ahead in
your path. If no vehicle is detected
in your path, ACC works like regular
cruise control. ACC uses camera and radar sensors. See
Radio
Frequency Statement on
page 13‑15 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the traction control
system (TCS) activates, the ACC
will automatically disengage. See
Traction Control System (TCS) on
page 9‑28. When road conditions
allow ACC to be safely used, the
ACC can be turned back on.
{WARNING
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid

WARNING (CONTINUED)
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, enter your lane,
or cross the vehicle’s path. Also
see“Alerting the Driver” in this
section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving on page 9‑3.
{WARNING
Adaptive Cruise Control will not
detect or brake for children,
pedestrians, animals, or other
objects.
