Press and release the StabiliTrak/
TCS button and the traction control
system turns off and the TCS
warning light comes on. Press and
release the button again to turn the
system back on. For information on
turning StabiliTrak off and on, see
StabiliTrak System following.
Launch Control (V8 with
Manual Transmission
Models Only)
Launch Control uses a form of
traction control specifically tuned to
optimize tire spin while launching the
vehicle during closed track events
and competitive driving. The feature
is activated when the vehicle is at
rest while in Competitive Mode.
SeeCompetitive Driving Mode on
page 8-37for more information.
At rest, if the accelerator pedal is
pressed to the floor with the clutch
engaged, the RPM is limited to a
predetermined level. A smooth, quick
release of the clutch while keeping
the accelerator pedal on the floor
will provide controlled wheel spin for
consistent acceleration. Complete
shifts as described inManual
Transmission on page 8-30.When in Competitive Mode the
StabiliTrak Off light comes on the
instrument panel cluster. Adjust your
driving accordingly. SeeCompetitive
Driving Mode on page 8-37for more
information.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modi cations on page 9-3
for more information.
Driving and Operating 8-35
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
computer 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.
If cruise control is being used when
StabiliTrak activates, the cruise
control will automatically disengage.
Press the cruise control button to
reengage when road conditions
allow. SeeCruise Control on
page 8-38for more information.The StabiliTrak/TCS button is
located in front of the shift lever.
When the system activates,
the StabiliTrak/Traction Control
System (TCS) warning light flashes
on the instrument panel cluster.
You may also hear a noise or feel
vibration in the brake pedal. This is
normal. Continue to steer the vehicle
in the intended direction.If there is a problem detected with
StabiliTrak, a Service StabiliTrak
message displays on the DIC and
the StabiliTrak/TCS warning light on
the instrument panel cluster comes
on. When this message and warning
light displays, the system is not
operational. Driving should be
adjusted accordingly. SeeRide
Control System Messages on
page 4-34andTraction Control
System (TCS)/StabiliTrak
®Light
on page 4-24for more information.
8-36 Driving and Operating
StabiliTrak comes on automatically
whenever the vehicle is started.
The system should be left on to
help assist with directional control
of the vehicle. If StabiliTrak needs
to be turned off, press and hold the
StabiliTrak/TCS button until theTraction Control Off light and the
StabiliTrak Off light come on the
instrument panel cluster. If the
system has been turned off, press
and release the StabiliTrak/TCS
button to turn the system back on.
Engine Drag Control (EDC)
EDC improves vehicle stability by
sensing if there is difference in speed
between the free rolling front wheels
and the rear drive wheels that often
occurs when the driver takes their
foot off the accelerator pedal on
slippery surfaces (snow, ice, etc.).
When this is detected, EDC sends
more torque to the rear wheels to
make sure all four wheels are
spinning at similar speeds, making
the vehicle more stable.
Competitive
Driving Mode
On vehicles with a V8 engine,
the driver can select this optional
handling mode by pressing the
StabiliTrak/TCS button two times
quickly while Traction Control and
StabiliTrak are turned on. When
the system is on, the StabiliTrak
Off light comes on and StabiliTrak
Competitive Mode will be displayed
in the Driver Information Center
(DIC). SeeRide Control System
Messages on page 4-34.
Driving and Operating 8-37
Setting Cruise Control
{WARNING
If you leave your cruise control
on when you are not using cruise,
you might hit a button and go into
cruise when you do not want to.
You could be startled and even
lose control. Keep the cruise
control switch off until you want
to use cruise control.
The cruise control buttons are
located on the outboard side of the
steering wheel.
5(On/Off):Press to turn the
cruise control system on and off.
An indicator light comes on in
the instrument panel cluster.
\(Cancel):Press to cancel cruise
control without erasing the set
speed from memory.
RES/+ (Resume/Accel):Move
the thumbwheel up to resume a set
speed or to accelerate to a higher
speed.
SET/−(Set/Coast):Move the
thumbwheel down to set a speed
or to decrease the speed.
To set a speed:
1. Press
5to turn cruise control
on. The indicator light in the
instrument panel cluster
comes on.
2. Get to the speed desired.3. Press the thumbwheel toward
SET/−and release it.
4. Take your foot off the accelerator
pedal.
When the brakes are applied, the
cruise control shuts off.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied, the cruise control is
disengaged. The indicator light
on the instrument panel cluster goes
out when the cruise is no longer
engaged. To return to the previously
set speed, press the thumbwheel
up toward RES/+ briefly when the
vehicle has reached a speed of
about 40 km/h (25 mph) or more.
This accelerates the vehicle to the
previously selected speed.
Driving and Operating 8-39
Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed.
•Disengage the cruise control,
but do not turn it off.
•If the cruise control system is
already engaged, press the
thumbwheel up toward RES/+
and hold it until the vehicle
accelerates to the desired speed,
and then release the switch.
To increase the speed in small
amounts, press the thumbwheel
up toward RES/+ briefly and then
release it. Each time this is done,
the vehicle goes about 1.6 km/h
(1 mph) faster.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already engaged,
•Push the thumbwheel toward
SET/−and hold until the desired
lower speed is reached, then
release it.
•To slow down in very small
amounts, push the thumbwheel
toward SET/−briefly. Each time
this is done, the vehicle goes
about 1.6 km/h (1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle’s speed.
When you take your foot off the
pedal, the vehicle will slow down
to the previously set cruise control
speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle’s
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle’s speed. When going
downhill, you might have to brake
or shift to a lower gear to maintain
the vehicle’s speed. When the
brakes are applied the cruise
control shuts off.Ending Cruise Control
There are three ways to end the
cruise control:
•Step lightly on the brake pedal
or clutch; when cruise control
disengages, the indicator light
on the instrument panel cluster
goes out.
•Press5to turn off the cruise
control system.
•Press\to disengage the cruise
control.
Erasing Speed Memory
The cruise control set speed
memory is erased when the cruise
control or the ignition is turned off.
8-40 Driving and Operating
The 8th digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle’s engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identi cation Number (VIN) on
page 11-1.
Recommended Fuel
If the vehicle has the 3.6L V6 engine
(VIN Code V), use regular unleaded
gasoline with a posted octane rating
of 87 or higher. If the octane rating is
less than 87, you might notice an
audible knocking noise when you
drive, commonly referred to as spark
knock. If this occurs, use a gasoline
rated at 87 octane or higher as soon
as possible. If you are using gasoline
rated at 87 octane or higher and you
hear heavy knocking, the engine
needs service.
If the vehicle has the 6.2L V8 engine
(VIN Code W) or the 6.2L V8 engine
(VIN Code J), use premium unleaded
gasoline with a posted octane
rating of 91 or higher. For best
performance, use premium unleaded
gasoline with a posted octane
rating of 93. You can also use
regular unleaded gasoline rated at
87 octane or higher, but the vehicle’s
acceleration could be slightly
reduced, and you might notice aslight audible knocking noise,
commonly referred to as a spark
knock. If the octane is less than 87,
you might notice a heavy knocking
noise when you drive. If this occurs,
use a gasoline rated at 87 octane
or higher as soon as possible.
Otherwise, you could damage the
engine. If you are using gasoline
rated at 87 octane or higher and you
hear heavy knocking, the engine
needs service.
Gasoline Speci cations
At a minimum, gasoline
should meet ASTM specification
D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel
Additives on page 8-45for
additional information.
8-44 Driving and Operating
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, move that
hand to the left. To move the trailer
to the right, move your hand to
the right. Always back up slowly
and, if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn
or lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you
may think other drivers are seeing
the signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes might
have to be used so much that they
would get hot and no longer
work well.Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts
too often under heavy loads and/or
hilly conditions. For vehicles with
a manual transmission, it is
better not to use the highest gear.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades,
the vehicle may show signs similar
to engine overheating. To avoid
this, let the engine run while
parked, preferably on level ground,
with the automatic transmission
in P (Park) for a few minutes
before turning the engine off.
