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.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.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.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message
is displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
a computer controlled system to assist the driver in
controlling the vehicle in difficult driving conditions.
You may feel or hear the system working and see the
ACTIVE HANDLING message displayed in the DIC.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able
to start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brakes.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn off the
radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminal locations on
each vehicle. See ªEngine Compartment Overviewº
in the Index for more information on location.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not
be covered by your warranty. See ªOverheated
Engine Protection Operating Modeº in the Index
for information on driving to a safe place in
an emergency.
If No Steam Is Coming From Your Engine
If you get an engine overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:

Climb a long hill on a hot day.

Stop after high
-speed driving.

Idle for long periods in traffic.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (
)
or THIRD (3) for automatic transmissions.
If you no longer have the overheat warning, you can drive.
Just to be safe, drive slower for about 10 minutes. If the
warning doesn't come back on, you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, idle the engine for
three minutes while you're parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see ªOverheated
Engine Protection Operating Modeº listed previously
in this section.
You may decide not to lift the hood but to get service
help right away.

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, see ªService and
Owner Publicationsº in the Index.
NOTICE:
We recommend that only fluid labeled
DEXRON-III be used, because fluid with
that label is made specially for your automatic
transmission. Damage caused by fluid 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 90F (32C) 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).
See ªScheduled Maintenance Servicesº in the Index
for the proper service intervals for the transmission fluid
and filter.
