Vehicle Care 9-9
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be too
serious. Sometimes the engine can
get a little too hot when the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows
as necessary.3. In heavy traffic, let the engine idle
in N (Neutral) while stopped. If it
is safe to do so, pull off the road,
shift to P (Park) or N (Neutral) and
let the engine idle.
If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle
the engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating Mode”
later in this section.
Power Steering Fluid
The power steering fluid reservoir is
located under the engine cover on
the driver side toward the front of the
engine compartment. SeeEngine
Compartment Overview on page 9-6.
When to Check Power
Steering Fluid
It is not necessary to regularly
check power steering fluid unless
you suspect there is a leak in
the system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
Vehicle Care 9-25
How to Check Power Steering
Fluid
Check the level after the vehicle
has been driven for at least
twenty minutes so the fluid
is warm.
To check the power steering fluid:
1. Turn the ignition key to
LOCK/OFF and let the engine
compartment cool down.
2. Remove the engine cover. Refer
toEngine Cover on page 9-9.
3. Wipe the cap and the top of the
reservoir clean.
4. Turn the cap counterclockwise
and pull it straight up.
5. Wipe the dipstick with a
clean rag.6. Replace the cap and completely
tighten it.
7. Remove the cap again and look
at the fluid level on the dipstick.
When the engine is hot, the
level should be at the hot MAX
level. When the engine is
cold, the fluid level should be
between MIN and MAX on
the dipstick.
What to Use
To determine what kind of fluid to
use, seeRecommended Fluids and
Lubricants on page 10-7. Always
use the proper fluid.
Washer Fluid
What to Use
When windshield washer fluid
is needed, be sure to read the
manufacturer’s instructions before
use. If operating vehicle in an area
where the temperature can fall
below freezing, use a fluid that has
sufficient protection against freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the reservoir is full. SeeEngine
Compartment Overview on page 9-6
for reservoir location.

Engine Oil (V6 Engine) Engine oil which meets GM Standard GM6094M and displays the
American Petroleum Institute Certified for Gasoline Engines starburst
symbol. To determine the proper viscosity for the vehicle’s engine, see
Engine Oil on page 9-10
.
Engine Oil (V8 Engines) The engine requires a special engine oil meeting GM Standard GM4718M.
Oils meeting this standard can be identified with the American Petroleum
Institute (API) Certified for Gasoline Engines starburst symbol. However,
not all synthetic API oils with the starburst symbol will meet this GM
standard. Look for and use only an oil that meets GM Standard GM4718M.
For the proper viscosity, see
Engine Oil on page 9-10.
