HIGH TIRE PRESSURE – (LF, LR, RF, RR)
(Except Z06):You will hear two chimes when this
message is displayed. To acknowledge the warning,
press RESET. After you press RESET, a message will
reappear every 10 minutes until this condition
changes. This message indicates that the pressure in
one of your tires is higher than 42 psi (290 kPa). Next to
the HIGH TIRE PRESSURE message, you can see
either LF (left front), LR (left rear), RF (right front) or RR
(right rear) to indicate to you which tire is higher than
42 psi (290 kPa). You can receive more than one
tire pressure message at a time. To read other
messages that may have been sent at the same time,
press RESET. If a tire pressure message appears on the
DIC, stop as soon as you can. Have the tire pressures
checked and set to those shown on your Tire Loading
Information Label. SeeExtended Mobility Tires
(Except Z06) on page 5-61andInation - Tire
Pressure on page 5-62.HIGH TRANS TEMP (Automatic Transmission
Only):You will hear four chimes when this message is
displayed. To acknowledge this warning, press the
RESET button. After you press the RESET button, the
message will be displayed every 10 minutes until
the condition changes. If you do not press RESET, the
message remains on the display until the condition
changes.
If the transmission fluid temperature rises above 270°F
(132°C) or rises rapidly, this message is displayed.
The transmission may shift gears or apply the torque
converter clutch to reduce the fluid temperature. Driving
aggressively or driving on long hills can cause the
transmission fluid temperature to be higher than normal.
If this message appears, you may continue to drive at
a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230°F (110°C). The transmission fluid temperature
can be monitored with the GAGES button on the
DIC. SeeAutomatic Transmission Fluid on page 5-20.
You should also check the engine coolant temperature.
If it is also hot, seeEngine Overheating on page 5-26.
If the HIGH TRANS TEMP message is displayed during
normal vehicle operation on flat roads, your vehicle
may need service. See your dealer for an inspection.

Automatic Transmission Fluid
How to Check
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to your dealer
service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at your dealer service
department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 7-11.
Notice:We recommend you use only uid labeled
DEXRON
®-III, because uid with that label is
made especially for your automatic transmission.
Damage caused by uid other than DEXRON
®-III is
not covered by your new vehicle warranty.Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
•In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•In hilly or mountainous terrain.
•High performance operation.
If you do not use your vehicle under one of these
conditions, change the fluid and filter every
100,000 miles (166 000 km).
SeeScheduled Maintenance on page 6-4for the proper
service intervals for the transmission fluid and filter.

(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
-In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
-In hilly or mountainous terrain.
-Uses such as high performance operation.
(i)Drain, ush and rell cooling system. See Engine
Coolant on page 5-23for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and filler neck.
Pressure test the cooling system and pressure cap.
Owner Checks and Services
These owner checks and services should be performed
at the intervals specified to help ensure the safety,
dependability and emission control performance of your
vehicle. Your GM Goodwrench dealer can assist you
with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-11.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-13for further
details.
Notice:It is important to check your oil regularly
and keep it at the proper level. Failure to keep your
engine oil at the proper level can cause damage
to your engine not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. SeeEngine
Coolant on page 5-23for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the windshield
washer tank and add the proper fluid if necessary.
