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.
2-23

Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system which locks the shift lever in PARK (P)
when the ignition is off. In addition, you have to fully
apply your regular brake before you can shift from
PARK (P) when the ignition is on. SeeAutomatic
Transmission Operation on page 2-25.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way
into PARK (P) and release the shift lever button as you
maintain brake application. Then press the shift lever
button and move the shift lever into the gear you wish.
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Put the vehicle in accessory mode.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and then shift to the drive gear
you want.
5. Have your vehicle inspected by your dealer as soon
as possible.
Parking Your Vehicle
(Manual Transmission)
Before you get out of your vehicle, move the shift lever
into REVERSE (R) and rmly apply the parking
brake. Once the shift lever has been placed into
REVERSE (R) with the clutch pedal pressed in, you can
turn the ignition off and release the clutch. If you
attempt to exit the vehicle without being in
REVERSE (R), the Driver Information Center (DIC) will
display SHIFT TO REVERSE and a chime will sound.
Notice:If you do not put a manual transmission in
REVERSE (R) before exiting your vehicle, your
vehicle will not be secured, the battery will drain
and could be damaged. Always put a manual
transmission in REVERSE (R) before shutting off the
engine and exiting the vehicle.

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat. It also makes things look farther away
than they really are.
