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 the upper
mark on the engine oil dipstick. You may need
to add oil. See ªAdding Oilº under ªEngineº in
the Index.
Engine Coolant Heater (If Equipped)
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.

Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the CHECK
ENGINE light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Engine Oil Pressure Gage
United States Canada
The 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. See ªEngine Oilº in the Index.
The engine oil pressure can also be displayed using the
GAGES button the the Driver Information Center
(DIC). See ªDriver Information Centerºin the Index.

2-83
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
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.
Check Gages Warning Light
This light will come on
briefly when you are
starting the engine. If the
light comes on and stays on
while you are driving, check
your gages to see if they are
in the warning areas.
This light can come on for the following reasons:

Low Oil Pressure

High Coolant Temperature

High or Low Battery Voltage

Low Fuel Level

2-85
You should reset the fuel information display every
time you refuel. To reset the display, press FUEL until
AVERAGE appears. Then, press RESET on the Driver
Information Center (DIC).
Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the
vehicle's power curves, see ªCapacities and
Specificationsº in the Index.

The selections that you choose will remain in the
HUD display until they are changed.
Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES icon will illuminate in
the HUD. View your Driver Information Center (DIC)
for more information.
