downhill, or if the vehicle is facing
uphill and the gear position is in
R (Reverse). When backing down a
hill, select R (Reverse) to
disable HSA.Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.

.Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.

Track Driver Mode and Launch
Control are systems designed to
allow increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and
suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
These systems will not compensate
for driver inexperience or lack of
familiarity with the race track.
{Warning
Track Driver Mode and Launch
Control change the way
StabiliTrak and TCS perform and
should not be used on public
roads. These modes should only
be used on closed courses by
experienced drivers.
{Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Racing will result in the premature
wear of brakes, tires, and driveline
components. Inspect and replace
components as necessary.

After the vehicle is launched, the
system continues in Track
Driver Mode.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand, or gravel. When
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. The
limited-slip rear axle also gives the
driver enhanced control when
cornering hard or completing a
maneuver, such as a lane change.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Track Driver Mode
on page 9-36 andMaintenance
Schedule on page 11-2.
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
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.
If the vehicle has the StabiliTrak
®
system and begins to limit wheel
spin while using cruise control, the
cruise control will automatically disengage. See
Traction Control/
Electronic Stability Control on
page 9-32. If a collision alert occurs
when cruise control is activated,
cruise control is disengaged. See
Forward Collision Alert (FCA)
System on page 9-46. When road
conditions allow you to safely use it
again, the cruise control can be
turned back on.
If the brakes are applied, cruise
control disengages.

After completely passing a large
enough space bordered by two
vehicles or other objects, an audible
beep occurs and a red symbol
displays in the DIC.
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the instructions in the DIC.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will vibrate briefly as a
reminder to remove hands from the
steering wheel. Check surroundings
and continue braking or accelerating
as needed, and be prepared to stop
to avoid vehicles, pedestrians,
or objects. If the vehicle is inR (Reverse), but does not steer into
the expected space, this may be
because the system is maneuvering
the vehicle into a previously
detected space. The APA system
does not need service.
A DIC progress arrow displays the
status of the parking maneuver.
Depending on the space size,
additional maneuvers may be
required, and there will be additional
instructions. When changing gears,
allow the automatic steering to
complete before continuing the
parking maneuver. Upon completion
of a successful maneuver, APA will
beep and display a PARKING
COMPLETE message. Place the
vehicle in P (Park) for an automatic
transmission or in N (Neutral) with
the parking brake set for a manual
transmission.
APA may automatically disengage if:
.The steering wheel is used by
the driver.
.If the vehicle exceeds
10 km/h (6 mph).
.There is a failure with the APA
system.
.Electronic stability control or
antilock brakes are activated.
.An important vehicle message is
displayed in the DIC.
.An incoming call is received
through a connected phone.
Disconnect the phone from the
vehicle to prevent APA from
disengaging.
APA search is only available when
the vehicle speed is below 30 km/h
(18 mph).
The APA system is constantly
