pressure at any one of the vehicle's
brakes to help steer the vehicle in the
direction which you are steering.
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. SeeIf the
Vehicle Is Stuck 0173 and “Turning
the Systems Off and On ”later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak is
activated.
. 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. If the
condition persists, see your dealer.
Turning the Systems Off and On
The button for TCS and StabiliTrak is
on the center stack.

Magnetic Ride Control
The Magnetic Ride Control monitors
the suspension system.
Based on road conditions, steering
wheel angle, and vehicle speed, the
system automatically adjusts to
provide the best handling while
providing a smooth ride. The Tour and
Sport Modes will feel similar on a
smooth road.
Tour : Use for normal city and
highway driving. This setting provides
a smooth, soft ride.
Sport : Use where road conditions or
personal preference demand more
control. This setting provides more
“feel,” or response to road conditions. The vehicle is normally in Tour Mode.
Sport Mode is engaged when the shift
lever is placed in M (Manual Mode).
When the shift lever is placed in D
(Drive) the system will revert back to
Tour Mode.
The Driver Information Center (DIC)
briefly displays the appropriate
message on vehicle startup or when a
new mode is selected. See
Ride Control
System Messages 0141.
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.

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
air springs 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
air springs 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. 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.
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).

Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. The following gap is
the following time (or distance)
between your vehicle and a vehicle
detected directly ahead in your path, moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak
®electronic stability
control system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0188. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak electronic stability control
system is disabled.

feel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when: .
The sensors are blocked.
. The Traction Control System (TCS)
or electronic stability control
system has activated or been
disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system.
The ACC active symbol will not be
displayed when ACC is no longer
active.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type ”and “Go Notifier” in
