Engine Coolant Heater
If your vehicle has this feature, in very cold weather
0°F (−18°C) or colder, the engine coolant heater
can help. You will get easier starting and better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located on the driver’s side of the
engine compartment, behind the battery.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

AUTOMATIC OVERDRIVE (D):This position is for
normal driving with the automatic transaxle. If you
need more power for passing, and you are:
Going less than about 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push your
accelerator all the way down.
LOW FOUR (L4):This position is also used for
normal driving, however, it offers more power and lower
fuel economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose LOW FOUR (L4)
instead of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When going down a steep hill.
LOW TWO (L2):This position gives you more
power but lower fuel economy than AUTOMATIC
OVERDRIVE (D). You can use LOW TWO (L2) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also want
to use your brakes off and on.
Notice:Do not drive in LOW TWO (L2) for more
than 25 miles (40 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.Use AUTOMATIC OVERDRIVE (D) or LOW FOUR
(L4) as much as possible. Do not shift into
LOW TWO (L2) unless you are going slower than
65 mph (105 km/h) or you can damage your engine.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Transaxle Overheating
If the transaxle uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-31for
more information. When the transaxle overheats it will go
into a protection mode and will default shift into fth gear
if in the AUTOMATIC OVERDRIVE (D) position, or
second gear if in the LOW TWO (L2) position. Continue
driving the vehicle in either position depending on the
required vehicle speed and load. Once the uid
temperature lowers to the normal temperature range,
the transaxle will return to the normal shift patterns.
Towing or driving on long hills can cause the transaxle
uid temperature to be higher than normal. If the
transaxle uid temperature will not cool, you may
need to pull over and check the transaxle uid level.
You should also check the engine coolant temperature.
If it is hot, seeEngine Overheating on page 5-23.

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-38.
1. Hold the brake pedal down and set the
parking brake.
2. Move the shift lever into the PARK (P) position
by holding in the button on the shift lever and
pushing it all the way toward the front of the vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pushing
the button. If you can, it means that the shift lever
was not fully locked into PARK (P).

Traction Control System (TCS)
Warning Light
Your vehicle may have a
traction control system
warning light. The traction
control system warning
light may come on for the
following reasons:
For vehicles equipped with the traction control
system and front-wheel drive, this light will come on
and stay on if you turn the system off by pressing
the traction control button located on the instrument
panel above the audio system. To turn the system
back on, press the button again. The warning
light should go off. SeeTraction Control System
(TCS) on page 4-9for more information.
For vehicles equipped with all-wheel-drive, this light
will come on and stay on when the all-wheel-drive
system is unable to protect for overheating
under extended heavy all-wheel-drive usage.
If there is an engine-related and brake system
problem that is specically related to traction control,
the traction control system will turn off and the
warning light will come on.If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Low Traction Light
If your vehicle has
the Traction Control
System (TCS) and has
front-wheel-drive, this
light will come on when
the system is limiting
wheel spin.
If your vehicle has all-wheel-drive, this light will come
on when the all-wheel-drive system is protecting
itself from overheating due to extended heavy all wheel
drive usage.
You may feel or hear the system working, but this is
normal. The roads may be slippery if this light comes on.
Adjust your driving accordingly.
The light will stay on for a few seconds after the system
stops limiting wheel spin. This light should also come
on for a few seconds when you start your vehicle.
If it does not, have your vehicle serviced.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating
on page 5-23for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-23.
Your vehicle could be damaged, and it might not
be covered by your warranty. Never drive with
the engine coolant temperature warning light on.
This light will also come on when starting your vehicle.
If it doesn’t, have your vehicle serviced.
This light will ash when the transaxle has overheated.
See “Transaxle Overheating”, underAutomatic
Transaxle Operation on page 2-19, for more information.
Engine Coolant Temperature Gage
This gage measures
the temperature of
the vehicle’s engine.
If the indicator needle moves into the shaded area,
the engine is too hot. A temperature indicator light
will turn on.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

The traction control system
can be turned off by
pressing the traction
control button, located
on the instrument panel
above the audio system.
The traction control system can be activated again by
pressing the traction control button.
If the system is limiting wheel spin when you press
the button, the traction control off light will appear on the
instrument panel cluster. The system will not turn off
until there is no longer a current need to limit wheel
spin. You can turn the system back on at any time by
pressing the button again. If the light does not come
on, you may not have traction control and your vehicle
should be serviced by a dealer.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information.All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin
to slip, the rear wheels will automatically begin to
drive the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
This light will come on
when engine torque is
reduced to protect
the AWD system from
overheating. You may
feel or hear a change
in engine output, but
this is normal.
During heavy AWD applications, the engine torque
may be reduced to protect AWD system components.
If the vehicle is exposed to extended heavy AWD
usage, the AWD system will shut itself off to protect
the system from overheating. When the system
cools down, the AWD system will activate itself again
automatically; this cool-down can take up to 20 minutes
depending on outside temperature and vehicle use.
4-10

If the AWD system is unable to protect the system from
overheating, the traction off light will come on to indicate
no protection capability. If this light comes on, take your
vehicle in for service.
Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power steering
assist because the electric power steering system is not
functioning, you can steer, but it will take more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time,
you may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems, such as abnormally high steering effort for
a prolonged period of time, contact your dealer for
service repairs.
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 your 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 apply the brakes. Both control
systems — steering and braking — have to do their
work where the tires meet the road. Unless you
have four-wheel anti-lock brakes, adding the hard
braking can demand too much of those places.
You can lose control.

If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
In order to free your vehicle when it is stuck, you
will need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as
rocking can help you get out when you are stuck,
but you must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of
the vehicle can overheat. That could cause
an engine compartment re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning your wheels can destroy parts
of your vehicle as well as the tires. If you spin
the wheels too fast while shifting your transaxle
back and forth, you can destroy your transaxle. See
Rocking Your Vehicle to Get It Out on page 4-31.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-61.
