tells you if there could be
a problem with your
engine oil pressure.
The light goes on when you turn your key to ON or
START. It goes off once you start your engine.
That’s a check to be sure the light works. If it

message by clearing it from the display, you still
must reset the engine oil life system separately.
For more information on resetting the engine oil life
system, seeEngine Oil Life System on page 363.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the tire
pressure in one of the tires needs to be checked.
This message also displays LEFT FRONT,
RIGHT FRONT, LEFT REAR, or RIGHT REAR to
indicate which tire needs to be checked. You
can receive more than one tire pressure message
at a time. To read the other messages that
may have been sent at the same time, press the

OIL PRESSURE LOW STOP ENGINE
Notice:If you drive your vehicle while
the engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the instrument panel
cluster and/or DIC, stop the vehicle as soon as
possible. Do not drive the vehicle until the
cause of the low oil pressure is corrected. See
Engine Oil on page 360for more information.
This message displays when the vehicle’s
engine oil pressure is low. The oil pressure light
may also appear on the instrument panel
cluster. SeeOil Pressure Light on page 211.
A multiple chime sounds when this message is
displayed. SeeEngine Oil on page 360for
more information.
Stop the vehicle immediately, as engine damage
can result from driving a vehicle with low oil
pressure. Have the vehicle serviced by your dealer

Engine Oil
Your vehicle may have
an oil pressure light on
the instrument cluster.
There is also an OIL PRESSURE LOW STOP
ENGINE message on the Driver Information
Center (DIC). If the light and/or message appears,
check the engine oil level right away. For more
information, see “OIL PRESSURE LOW STOP
ENGINE” underDIC Warnings and Messages on
page 220andOil Pressure Light on page 211.
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 356
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.

Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be
driven to a safe place in an emergency. Should an
hot engine condition exist, an overheat protection
mode which alternates ring groups of cylinders
helps prevent engine damage. In this mode, there is
a loss in power and engine performance. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss and change the oil. SeeEngine Oil on
page 360.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Electric Engine Cooling Fans
B. Coolant Surge Tank and Pressure Cap
Some vehicles may be equipped with an
engine driven fan, as well as the electric
pusher fans (A) which are located behind the
vehicle’s grille.

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant and
the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
If no coolant is visible in the surge tank, add
coolant as follows:
1. You can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pressure cap
and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
(left) about one-quarter turn and then stop.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.

Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your
vehicle’s interior, maintain adequate ventilation by
opening your vehicle’s doors and windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.
Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.
Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Neverapply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.

All cleaning agents should be ushed promptly
and not allowed to dry on the surface, or they
could stain. Dry the nish with a soft, clean
chamois or an all-cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause water to
enter the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions underWashing
Your Vehicle on page 447.
Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint nish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 452.Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
The vehicle has a basecoat/clearcoat paint
nish. The clearcoat gives more depth and gloss
to the colored basecoat. Always use waxes
and polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and
tar, tree sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle’s
nish if they remain on painted surfaces. Wash
the vehicle as soon as possible. If necessary, use
non-abrasive cleaners that are marked safe for
painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather, and chemical fallout that can take their
toll over a period of years. To help keep the
paint nish looking new, keep the vehicle in a
garage or covered whenever possible.
