and could be damaged. Always put a manual
transmission in REVERSE (R) before shutting off the
engine and exiting the vehicle.
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, the 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, seeEngine Oil on page 5-13. 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.
Vehicles with the Z51 performance package have
greaseable outer ends on both of the rear toe-links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. SeeScheduled
Maintenance on page 6-4andRecommended Fluids
and Lubricants on page 6-12. If you use the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer for lubrication
and make sure any needed repairs are made at once.
Proper procedures for performing these services can be
found in the service manual. SeeService Publications
Ordering Information on page 7-11.

Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console
or glove box lamps are accidentally left on. If you leave
any of these lamps on, they will automatically time-out
after about 20 minutes. To reset it, all of the above
lamps must be turned off or the ignition key on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to

Engine Oil Pressure Gage
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. SeeEngine Oil on page 5-13.The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
SeeDriver Information Center (DIC) on page 3-49.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States

The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.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 inated to the
recommended pressure?
Weather Forecasts:What is 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?
