Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving
to these conditions. It is important
to slow down on slippery surfaces
because stopping distance is longer
and vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear.
Any sudden changes could cause
the tires to slide. You might not
realize the surface is slippery until
the vehicle is skidding. Learn to
recognize warning clues — such as
enough water, ice, or packed snow
on the road to make a mirrored
surface — and slow down when
you have any doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only
the braking skid.Competitive Driving
Competitive driving may affect the
vehicle warranty. See the warranty
book before using the vehicle for
racing or other competitive driving.
The new vehicle break-in must be
performed before the vehicle is used
for competitive driving. SeeNew
Vehicle Break-In on page 8-16.
Notice:If you use your vehicle
for competitive driving, the engine
may use more oil than it would
with normal use. Low oil levels
can damage the engine. Be sure
to check the oil level often during
competitive driving and keep the
level at or near the upper mark
that shows the proper operating
range on the engine oil dipstick.
For information on how to add oil,
seeEngine Oil on page 9-10.For competitive driving, it is
recommended that the brake fluid be
replaced with a high performance
brake fluid that has a dry boiling point
greater than 279°C (534°F). After
conversion to the high performance
brake fluid, follow the brake fluid
service recommendations outlined
by the fluid manufacturer. Do not
use silicone or DOT-5 brake fluids.
If the vehicle is used for racing,
competitive driving, sustained high
speed, or events that generate
excessive wheel slip, the rear axle
fluid temperatures will be higher
than would occur in normal driving.
We recommend that the rear axle
fluid be drained and refilled with
new fluid after every six hours of
racing or competitive driving.
SeeRecommended Fluids and
Lubricants on page 10-7for what
fluid to use.
Driving and Operating 8-7
Regularly inspect the driveshaft/
propshaft couplings and halfshaft
boots for cracking or grease leakage.
It is not recommended that the
vehicle be used for ongoing race
track/competitive driving.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in
a quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they actually ride on the
water. This can happen if the road
is wet enough and you are going
fast enough. When your vehicle
is hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
•Allow extra following distance.
•Pass with caution.
•Keep windshield wiping
equipment in good shape.
•Keep the windshield washer fluid
reservoir filled.
•Have good tires with proper tread
depth. SeeTires on page 9-48.
•Turn off cruise control.
8-8 Driving and Operating
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the road,
creating less traction or grip. Wet ice
can occur at about 0°C (32°F) when
freezing rain begins to fall, resulting
in even less traction. Avoid driving on
wet ice or in freezing rain until roads
can be treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
TheAntilock Brake System (ABS)
on page 8-31improves vehicle
stability during hard stops on
a slippery roads, but apply the
brakes sooner than when on
dry pavement.Allow greater following distance
on any slippery road and watch for
slippery spots. Icy patches can occur
on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
Turn off cruise control, if equipped,
on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 12-6.
To get help and keep everyone
in the vehicle safe:
•Turn on the hazard warning
flashers.
•Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
•Clear away snow from
around the base of your
vehicle, especially any that
is blocking the exhaust pipe.
•Check again from time to
time to be sure snow does
not collect there.
•Open a window about 5 cm
(two inches) on the side of
the vehicle that is away from
the wind to bring in fresh air.
(Continued)
8-10 Driving and Operating
WARNING (Continued)
•Fully open the air outlets on
or under the instrument panel.
•Adjust the Climate Control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control System
in the Index.
For more information about carbon
monoxide, seeEngine Exhaust on
page 8-25.
Snow can trap exhaust gases
under your vehicle. This can cause
deadly CO (carbon monoxide) gas
to get inside. CO could overcome
you and kill you. You cannot see it
or smell it, so you might not know
it is in your vehicle. Clear away
snow from around the base of
your vehicle, especially any that
is blocking the exhaust.Run the engine for short periods
only as needed to keep warm,
but be careful.
To save fuel, run the engine for only
short periods as needed to warm the
vehicle and then shut the engine off
and close the window most of the
way to save heat. Repeat this until
help arrives but only when you feel
really uncomfortable from the cold.
Moving about to keep warm also
helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help with
the headlamps. Do this as little as
possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn
the traction system off and use
the rocking method.
{WARNING
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be injured.
The vehicle can overheat, causing
an engine compartment fire or
other damage. Spin the wheels as
little as possible and avoid going
above 55 km/h (35 mph) as shown
on the speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 9-68.
Driving and Operating 8-11
Rocking the Vehicle to
Get it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth between
R (Reverse) and a forward gear,
or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on
the accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 9-87.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory-installed options.
Two labels on the vehicle
show how much weight it
may properly carry, the Tire
and Loading Information label
and the Certification label.{WARNING
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR), or
either the maximum front or
rear Gross Axle Weight Rating
(GAWR). If you do, parts on
the vehicle can break, and
it can change the way your
vehicle handles. These could
cause you to lose control and
crash. Also, overloading can
shorten the life of the vehicle.
8-12 Driving and Operating
Manual Mode
Tap Shift
Tap Shift allows the driver to
manually control the automatic
transmission. To use Tap Shift, the
shift lever must be in M (Manual
Mode). Vehicles with this feature
have flags on the top of the steering
wheel to indicate to the driver the
location of the switches on the back
of the steering wheel. Tap the leftswitch to downshift, and the right
switch to upshift. A display in the
Driver Information Center will show
which gear the vehicle is in.
SeeDriver Information Center (DIC)
on page 4-27for more information.
While using the Tap Shift feature,
the vehicle will have firmer, quicker
shifting for increased performance.
You can use this for sport driving or
when climbing or descending hills, to
stay in gear longer, or to down shift
for more power or engine braking.
The transmission will only allow
you to shift into gears appropriate
for the vehicle speed and engine
Revolutions Per Minute (RPM).
The transmission will not
automatically shift to the next higher
gear if the engine RPM is too high.
If shifting is prevented for any
reason, the message Shift Denied
will appear in the DIC, indicating
that the transmission has notshifted gears. While in the Tap
Shift mode, the transmission will
not automatically downshift on
hard acceleration.
When coasting to a stop, the
V6 transmission will automatically
downshift to 1 (First) gear, and the
V8 transmission will automatically
downshift to 2 (Second) gear.
A 1 (first) gear start can be selected
using the Tap Shift controls on
V8 models When accelerating from
a stop the transmissions will hold
these gears until the driver manually
selects higher gears using the Tap
Shift controls.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear ratio allows you
to gain more traction on slippery
surfaces.
Driving and Operating 8-29
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
The system utilizes engine and
braking controls to control wheel
spin during acceleration at all driving
speeds for maximum driver control
regardless of conditions. When the
system senses impending wheel slip
during acceleration, it signals the
throttle control to reduce drive wheel
torque. Under extreme situations,
such as going from pavement to ice
during acceleration, the system
will selectively apply the brakes to
maintain control. The system may
be heard or felt while it is working,
but this is normal.The TCS/StabiliTrak warning light
flashes when the traction control
system is limiting wheel spin.
The StabiliTrak/TCS warning light
comes on solid if there is a problem
with the traction control system.
SeeTraction Control System
(TCS)/StabiliTrak
®Light on
page 4-24for more information.
If the light stays on, see your
dealer/retailer for service. When the
TCS/StabiliTrak warning light is on,
the system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the systemshould 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. Also, turn TCS off while
in deep snow or on loose gravel,
to assist vehicle motion at lower
speeds. SeeIf the Vehicle is Stuck
on page 8-11for more information.
See alsoWinter Driving on
page 8-10for information on using
TCS when driving in snowy or icy
conditions.
To turn the system off, press
and release the StabiliTrak/TCS
button located on the console
in front of the shift lever.
8-34 Driving and Operating
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.
