5-9 Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency; you may
drive up to 50 miles (80 km). Towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See ªEngine Oilº in
the Index.
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
CAUTION: (Continued)

6-11 Underhood Lamp
Turn the parking lamps on to operate the underhood
lamp. The underhood lamp will come on when the hood
is opened.
Engine Oil
A CHECK OIL LEVEL message will appear when the
engine oil is approximately 1 quart (1L) low. If the
message is displayed, check the dipstick level and add
oil as needed.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick is
located directly behind the
radiator. The black handle
says ENGINE OIL on it.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.

The system won't detect dust in the oil. So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the Oil Life Indicator whenever the oil is changed.
How to Reset the Oil Life Indicator
After the oil has been changed, display the ENGINE
OIL LIFE message by pressing the INFO button. Then
press and hold the INFO RESET button until the display
shows 100% ENGINE OIL LIFE. This resets the oil life
index. The message will remain off until the next oil
change is needed. The percentage of oil life remaining
may be checked at any time by pressing the INFO
button several times until the ENGINE OIL LIFE
message appears. For more information on the Oil Life
feature, see ªOil Life Indicatorº in the Index.What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer's warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

NOTICE:
We recommend you use only fluid labeled
DEXRON
-III, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON

-III
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under ªHow to Check.º
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
How to Reset the Transaxle Fluid
Change Indicator
After the transaxle fluid has been changed, display the
TRANS FLUID LIFE message by pressing the INFO
button. Then press and hold the INFO RESET button
until the display shows ª100.º This resets the transaxle
fluid life index. The message will remain off until the
next transaxle fluid change is needed. The percentage of
transaxle fluid life remaining may be checked at any
time by pressing the INFO button several times until the
TRANS FLUID LIFE message appears.
Surge Tank Pressure Cap
NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure
-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Two and one
-half turns are
required to seal the cap.
If the surge tank pressure cap needs to be replaced, a
GM cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced, a GM
thermostat is recommended.

NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral
-based oil, such as engine
oil, in your brake system can damage brake
system parts so badly that they'll have to be
replaced. Don't let someone put in the
wrong kind of fluid.

If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See ªAppearance Careº in
the Index.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make a
high
-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Your vehicle also has electronic wear sensors that let
you know when the brake pads are significantly worn
and new pads are needed. The CHANGE BRAKE
PADS message will be displayed on the Driver
Information Center when the brake pads are worn and
need to be replaced. (See ªChange Brake Pads Messageº
in the Index.)
