TRANSMISSION HOT IDLE ENGINE
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while the
transmission temperature warning is displayed.
This message displays when the transmission uid in
your vehicle is too hot. Stop the vehicle and allow
it to idle until it cools down. If the warning message
continues to display, have the vehicle serviced by your
dealer/retailer as soon as possible.

This message displays when the trunk is not closed
completely. Make sure that the trunk is closed
completely. SeeTrunk on page 2-13.
3-65

When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
You can turn the system on or off at any time by pressing
the traction control system button located on the console
or on the end of the column shifter. The DIC will display
TRACTION CONTROL OFF when you press the button,
and part of the traction control system is disabled. Your
vehicle will still have brake-traction control, but will not be
able to use the engine speed management system. You
may still hear system noises as a result of the
brake-traction control coming on. If the controller detects
excessive wheel spin in this mode, the traction control
system and StabiliTrak
®indicator light may blink.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you may want to “rock” your vehicle in an
attempt to free it. SeeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-18for more information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
StabiliTrak®System
Your vehicle may have this feature. The StabiliTrak®
system is an advanced computer controlled system that
helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power. The
StabiliTrak
®system comes on automatically whenever
you start your vehicle. The system cannot be turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system and
StabiliTrak
®warning light on the instrument panel
cluster will be on after rst driving the vehicle and
exceeding 19 mph (30 km/h) for 30 seconds. The
StabiliTrak
®system is off until the light has turned off.
This could take up to 15 minutes.
The traction control system and StabiliTrak
®warning light
on the instrument panel cluster will ash when the system
is operating. SeeTraction Control System (TCS) Warning
Light on page 3-40,StabiliTrak
®Indicator Light on
page 3-41andDIC Warnings and Messages on
page 3-56for more information. You may also feel or
hear the system working. This is normal.
4-6

The SERVICE STABILITRAK message will be displayed
and the traction control system and StabiliTrak®warning
light on the instrument panel cluster will come on if there
is a problem with the system. When this light and the
SERVICE STABILITRAK message are on, the system is
not operational. Adjust your driving accordingly.
Panic Brake Assist
Your vehicle may have a panic brake assist system that
monitors the intention of the driver while braking. If
the system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver
to maintain brake application. When this happens the
brake pedal will feel easier to push. Just hold the brake
pedal down rmly and let the system work for you.
You may feel the brakes vibrate, or you may notice
some noise but this is normal. The brakes will return to
normal operation after the brake pedal has been
released.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of the tires and the road surface, the angle at
which the curve is banked, and your speed. While you are
in a curve, speed is the one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do
their work where the tires meet the road. Adding
the sudden acceleration can demand too much of those
places. You can lose control. SeeTraction Control
System (TCS) on page 4-5andStabiliTrak
®System
on page 4-6.
What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.

Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the overow tube on the radiator ller neck.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Engine Overheating
You will nd a warning light about a hot engine as well
as an engine coolant temperature gage on your
vehicle’s instrument panel cluster.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood. Stay
away from the engine if you see or hear steam
coming from it. Turn it off and get everyone
away from the vehicle until it cools down. Wait
until there is no sign of steam or coolant
before you open the hood.
If you keep driving when the vehicles engine is
overheated, the liquids in it can catch re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
SeeOverheated Engine Protection Operating
Mode on page 5-30for information on driving
to a safe place in an emergency.
Notice:If your engine catches re because you keep
driving with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered by
your warranty. SeeOverheated Engine Protection
Operating Mode on page 5-30for information on
driving to a safe place in an emergency.
