Battery Voltage/BATTERY VOLTS: If you select this
item, the current battery voltage is displayed. If the
voltage is in the normal range, the display will have OK
after it. For example, the display may read 13.2 Battery
Volts OK.
If there is a problem with the battery charging system,
there are four possible DIC messages that may be
displayed. See ªDriver Information Center (DIC)
Messagesº later in this section for more information.
Engine Oil Life/ENGINE OIL LIFE: If you select
this item, the percentage of remaining oil life is
displayed. If you see 99% Oil Life on the display, that
means that 99% of the current oil life remains.
When the oil life is depleted, the Change Engine Oil
message will appear on the display. You should change
the engine oil as soon as possible within 200 miles. Be
sure to keep a written record of the mileage and date of
the oil change so you will have it for future reference.
When you reset the Change Engine Oil message by
clearing it from the display, you still must reset the
engine oil life monitor separately. For more information
on resetting the engine oil life monitor, see ªOil Life
Monitor, How to Resetº in the Index.The engine oil life monitor does not check the amount
of oil your vehicle has, so you should check the oil level
periodically. See ªEngine Oilº in the Index for more
information.
Transmission Fluid Life/TRANS FLUID LIFE
(Automatic Transmission Only): If you select this
item, the percentage of remaining transmission fluid life
is displayed. If you see 99% Trans Fluid Life on the
display, that means that 99% of the current transmission
fluid life remains.
When the transmission fluid life is depleted, the Change
Transmission Fluid message will appear on the display.
You should change the engine oil as soon as possible
within 200 miles. Be sure to keep a written record of the
mileage and date of the oil change so you will have it
for future reference.
When you reset the Change Transmission Fluid message
by clearing it from the display, you still must reset the
transmission fluid life monitor separately. For more
information on resetting the engine oil life monitor, see
ªTransmission Fluid Life Monitor, How to Resetº in
the Index.

4-41 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

start your engine,

shift into a gear, and

release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don't
overfill), engine oil, axle lubricant, drive belt, cooling
system and brake system. Each of these is covered in
this manual, and the Index will help you find them
quickly. If you're trailering, it's a good idea to review
this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

Automatic Transmission Fluid
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 your vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked
by your dealer or service center when you have your
oil changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:

In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.

In hilly or mountainous terrain.

When doing frequent trailer towing.

Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.NOTICE:
We recommend you use only fluid labeled
DEXRON-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than
DEXRON
-III is not covered by your new
vehicle warranty.
