Engine Oil Pressure GageThe engine oil pressure gage shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi
(140 to 550 kPa). In certain situations such as
long, extended idles on hot days, it could read
as low as 6 psi (40 kPa) and still be considered
normal. It may vary with engine speed, outside
temperature and oil viscosity, but readings above
the shaded area show the normal operating
range. Readings in the shaded area tell you
that the engine is low on oil, or that you might
have some other oil problem. SeeEngine Oil on
page 333.
The engine oil pressure can also be displayed
using the GAGES button on the Driver Information
Center (DIC). SeeDriver Information Center (DIC)
on page 207.

low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as
soon as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
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 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
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
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.

the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure
cap, is cool before you do it. SeeEngine
Coolant on page 347for more information.
If no coolant is visible in the surge tank, add
coolant as follows:
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure, and if
you turn the coolant surge tank pressure
cap — even a little — they can come out
at high speed. Never turn the cap when
the cooling system, including the coolant
surge tank pressure cap, is hot. Wait
for the cooling system and coolant
surge tank pressure cap to cool if you
ever have to turn the pressure cap.
{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.

When cleaning your vehicle’s interior, only use
cleaners specically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which
they were not intended. Use glass cleaner only on
glass. Remove any accidental over-spray from
other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the integrated radio antenna and the rear
window defogger. When cleaning the glass
on your vehicle, use only a soft cloth and
glass cleaner.
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.
Never apply 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.
