When the fuel tank is low on fuel,
a Fuel Level Low message will
appear on the Driver Information
Center (DIC). For more information
seeFuel System Messages on
page 4-33.
Here are some situations that can
occur with the fuel gage. None of
these indicate a problem with
the fuel gage.
•At the gas station, the fuel pump
shuts off before the gage
reads full.
•It takes a little more or less fuel to
fill up than the fuel gage indicated.
For example, the gage may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank’s capacity
to fill the tank.
•The pointer on the fuel gage is on
empty when the ignition is off.
Engine Oil
Pressure Gage
The oil pressure gage, located in
front of the shifter, shows the engine
oil pressure in psi (pounds per
square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but readings above the low
pressure zone indicate the normal
operating range. When the oil
pressure reaches the low pressure
zone, a message appears in the
Driver Information Center (DIC). United States

Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel fill.
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 9-6
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 this is not done,
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.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one liter/quart of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Speci cations
on page 11-2.
Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range,
the engine could be damaged.
SeeEngine Compartment Overview
on page 9-6for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the
way back in when through.
