Running Your Engine While You
Are Parked (Automatic
Transmission)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust Ð with CO Ð can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
ªWinter Drivingº in the Index.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. Don't leave your vehicle when the engine
is running unless you have to. If you've left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See
Shifting Into Park (P) (Automatic
Transmission) on page 2-31.

Roof Panel
Your vehicle may have a removable roof panel.
Removing the Roof Panel
{CAUTION:
Don't try to remove a roof panel while the
vehicle is moving. Trying to remove the roof
panel while the vehicle is moving could cause
an accident. The panel could fall into the
vehicle and cause you to lose control, or it
could ¯y off and strike another vehicle. You or
others could be injured. Remove the roof panel
only when the vehicle is parked.
Until you are sure you can remove the panel alone,
have someone help you.
Notice:To avoid damage to the roof panel, paint
and weatherstripping, do not drop or rest it on
its edges. Place the roof panel in the egg-shaped
stowage receivers after removing it from the vehicle.1. Park on a level surface, set the parking brake ®rmly
and shift an automatic transmission into PARK (P).
Shift a manual transmission into REVERSE (R).
2. Turn the ignition key to OFF. Lower both sun visors
and turn them toward the door glass.
3. Open the rear hatch and remove any items that may
interfere with proper storage of the roof panel.
4. Make sure to install the two egg-shaped stowage
receivers into the ¯oor of the rear storage
compartment. Secure both receivers into their
proper positions by turning them counterclockwise.

Lowering the Convertible Top
Notice:Don't leave the convertible out with the top
down for any long periods of time. The sun and
rain can damage the seat material and other things
inside the vehicle.
1. Set the parking brake ®rmly. Shift an automatic
transmission into PARK (P). Shift a manual
transmission into REVERSE (R).
2. Turn the ignition key to OFF. Lower both sun visors
and turn them toward the door glass.
Notice:Before lowering the convertible top into the
storage area, be sure there are no objects in the
way of the folded, stored top. The weight of a stored
top on items in the storage area may cause the
convertible top back glass to break.3. Unlock the front of the convertible top by lowering
the latch handles and turning them inward. Push
the latch handles back to the up position.

7. Then move the top rearward to its fully-stored
position.
8. After the top is stored, apply one even push on the
center of the front edge (A) of the convertible top to
assure that the top is fully retracted.
9. Close the storage compartment lid (C) by closing
with a swift, ®rm motion.
Raising the Convertible Top
1. Park on a level surface, set the parking brake ®rmly
and shift an automatic transmission into PARK (P).
Shift a manual transmission into REVERSE (R).
Lower both windows and sun visors and turn
the ignition key to OFF.
2. Tilt the driver's seat forward and press the storage
compartment release button, or use the manual
release cable if battery power has been lost. Lift the
storage compartment lid (C).
(After pressing the release button, the driver and
passenger door glass should retract to the full-down
position, if they have not already been lowered.)

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 timeout
after about 15 minutes. To reset it, all of the above
lamps must be turned off or the ignition key must be
in 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
see things you need to see when it's dark
outside. Be sure to keep the HUD image dim
and placed low in your ®eld 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.
