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.

2-27 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is attached to the generator
bracket assembly, between the generator and the
windshield washer fluid tank.With the headlamps
closed, route the cord in the opening between the
headlamp door and the fender panel on the driver's
side of the vehicle. Do not pinch the cord when
closing the hood.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach,
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged in?
The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

2-33 One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1)
to SECOND (2).
You must complete the shift into FOURTH (4) to turn
off this feature. This helps you get the best possible
fuel economy.
After shifting to FOURTH (4), you may downshift
to a lower gear if you prefer.
NOTICE:
Do not try to force the shift lever into SECOND (2)
or THIRD (3) when the 1 TO 4 SHIFT light
comes on. Do not try to re
-engage FIRST (1)
after starting to shift into FOURTH (4). You will
damage your transmission. Shift only from
FIRST (1) to FOURTH (4) when the light
comes on.
This light will come on when:

The engine coolant temperature is higher than
169F (76C),

you are going 15 to 19 mph (24 to 31 km/h) and

you are at 21 percent throttle or less.

2-87 Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the shaded area, your engine
is too hot.
This means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
(The larger tic marks are in increments of 30
below
220
F (104
C) and in increments of 10
above
220
F (104
C).)
See ªEngine Overheatingº in the Index for
more information.
Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent
more serious damage to your vehicle. This system
is also designed to assist your service technician in
correctly diagnosing any malfunction.

2-92
Security Light
This light comes on to
remind you to arm your
theft
-deterrent system. If it
comes on and stays on when
your ignition is on, there
may be a problem with your
theft
-deterrent system.
See ªTheft
-Deterrent Systemº and ªPASS-Key Systemº
in the Index.
