2-26
Racing or Other Competitive Driving
See your Warranty Book before using your vehicle for
racing or other competitive driving.
NOTICE:
If you use your vehicle for racing or other
competitive driving, your engine may use more
oil than it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
For information on how to add oil, see ªAdding
Oilº under ªEngineº in the Index. After the
competitive driving, remove excess oil so that the
level on the dipstick is not above the upper mark
that shows the proper operating range.
Engine Coolant Heater (Canada Only)
The engine coolant heater is located on the driver's side
of the engine under the manifold.
In very cold weather, 0
F (
-18
C) or colder,
the engine coolant heater can help. You'll get easier
starting and better fuel economy during engine
warm
-up. Usually, the coolant heater should be
plugged in a minimum of four hours prior to starting
your vehicle. At temperatures above 32
F (0
C),
use of the coolant heater is not required.

Engine Oil
If the LOW OIL LEVEL message on the Driver
Information Center comes on, it means you need
to check your engine oil level right away. For more
information, see ªDriver Information Centerº in the
Index. You should check your engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It's a good idea to check your 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 ring
located near the coolant
surge tank. See ªEngine
Compartment Overviewº
in the Index for more
information on location.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
Pull out the dipstick and clean it with a paper towel or a
cloth, then push it back in all the way. Remove it again,
keeping the tip down.

When to Add Engine Oil
If the oil is at or below the ADD mark, you'll need to
add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use.
For engine oil crankcase capacity, see ªCapacities and
Specificationsº in the Index.
See ªRacing or Other Competitive Drivingº in the Index
for additional information on engine oil.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap
is located in the engine
compartment on top of
the valve cover on the
passenger's side of the
vehicle. See ªEngine
Compartment Overviewº
in the Index for more
information on location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.
