ENGINE RPM
If this message displays, the control system has
determined that continued operation at the existing
engine speed may lead to engine overheating.
Lower the engine speed by upshifting the
transmission or drive at a lower speed.
HEADLAMPS SUGGESTED
This message displays if it is dark enough outside
and the headlamps and Twilight Sentinel®
controls are off. This message informs the driver
that turning on the exterior lamps is recommended.
It has become dark enough outside to require
the headlamps and/or other exterior lamps. This
message also displays if the optional Rainsense™
wiping feature is on and the Twilight Sentinel
®
is off.
HIGH TRANS (Transmission) TEMP
(Temperature)
This message displays when the transmission uid
in your vehicle is too hot. Stop and allow your
vehicle to idle until it cools down or until this
message is removed.
HIGH VOLTAGE
This message displays when the electrical
charging system is overcharging. To avoid being
stranded, have the electrical system checked
by your dealer. You can reduce the charging
overload by using the accessories. Turn on the
lamps and radio, set the climate control on AUTO
and the fan speed on HI, and turn the rear
window defogger on. You can monitor battery
voltage on the DIC by pressing the information
button. The normal range is 11.5 to 15.5 volts
when the engine is running.
HOT ENGINE–A/C OFF

LOW OIL LEVEL
For correct operation of the low oil sensing
system, your vehicle should be on a level surface.
A false LOW OIL LEVEL message may display
if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil
level if the engine has been off for a short
period of time, and the oil level is never checked
while the engine is running. If the LOW OIL
LEVEL message displays, and your vehicle has
been parked on level ground with the engine off for
at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to
checking the oil level, make sure the engine has
been off for a few minutes and your vehicle is on a
level surface. Then check the dipstick and add
oil if necessary. SeeEngine Oil on page 377.
LOW OIL PRESSURE
If this message displays while the engine is
running, stop the engine and do not operate the
vehicle until the cause of low oil pressure is
corrected. Severe damage to the engine can
result. A multiple chime sounds when this
message is displayed.

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.

If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center
(DIC) appears, it means you need to check the
engine oil level right away. For more information,
see LOW OIL LEVEL and LOW OIL PRESSURE
underDIC Warnings and Messages on page 206.
You should check the engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It is a good idea to check the 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 handle is a yellow loop.
SeeEngine Compartment Overview on page 374
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

Change the uid and lter at the intervals listed in
Additional Required Services on page 467, and
be sure to use the uid listed inRecommended
Fluids and Lubricants on page 473.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 388.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Giving freezing protection down to−34°F
(−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
