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.

2-91 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 on the Driver Information Center (DIC).
See ªDriver Information Centerº in the Index.
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
Fuel Gage
Your fuel gage tells you
about how much fuel
you have left when the
ignition is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center
(DIC) display. When the needle approaches the E, LOW
FUEL will appear on the display. At this time, you still
have a little fuel left, but you should get more soon.

Head-Up Display (HUD) (If Equipped)
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 (6,250 rpm
on Z06), just prior to reaching the engine fuel
cut
-off mode. To better understand the vehicle's

--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure the cassette tape is in
good condition before you have your tape player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna (Z06)
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the rear quarter panel.

4-25
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated
to the recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?

Maps: Do you have up
-to-date maps?
Highway Hypnosis
Is there actually such a condition as ªhighway hypnosisº?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with the
same scenery, along with the hum of the tires on the road,
the drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don't let it happen
to you! If it does, your vehicle can leave the road in less
than a second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated,
with a comfortably cool interior.

Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.

If you get sleepy, pull off the road into a rest,
service or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness on
the highway as an emergency.

Engine Overheating
You will find an engine coolant temperature gage on the
instrument panel cluster and a COOLANT OVER
TEMP message on the Driver Information Center (DIC).
See ªEngine Coolant Temperature Gageº and ªCoolant
Over Temp DIC Messageº in the Index.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the messages
COOLANT OVER TEMP and REDUCED ENGINE
POWER are displayed, along with the Check Engine
light, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle to
be driven to a safe place in an emergency; you may drive
up to 50 miles (80 km).
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.
