Leaving Your Vehicle With the Engine
Running (Automatic Transmission Only)
CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold down
the regular brake pedal. See if you can move the shift
lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).

Shifting Out of PARK (P)
(Automatic Transmission)
CAUTION:
Before shifting out of PARK (P) you must fully
apply your regular brakes. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could
be injured.
Your vehicle has a Brake-Transmission Shift Interlock
(BTSI). You have to fully apply your regular brake
before you can shift from PARK (P) when the ignition
is in ON. See ªAutomatic Transmission Operationº in
the Index.
As a prompt, you will see a message in the Driver
Information Center (DIC) that will say PRESS BRAKE
BEFORE SHIFT within 15 seconds unless the brake
is pressed.If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- 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 can't
shift out of PARK (P), try this:
1. Turn the key to ACC.
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, put your manual
transmission in REVERSE (R) and firmly apply the
parking brake.

Running Your Engine While You're
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 Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
(See ªBlizzardº 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 firmly 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 ªShifting Into PARK (P)º in the Index.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works
like a standard axle most of the time, but when one
of the rear wheels has no traction and the other does,
this feature will allow the wheel with traction to move
the vehicle.

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 firmly
and shift an automatic transmission into PARK (P).
Shift a manual transmission into REVERSE (R).
Turn the ignition key to OFF. Lower both sunshades
and rotate them toward the door glass.
2. Open the rear liftgate and remove any items that may
interfere with proper storage of the roof panel.
Also install the two egg
-shaped stowage receivers
into the floor of the rear storage compartment.
Secure both receivers into their proper positions by
turning them counterclockwise.
3. Lower the windows and open the doors.

2-69 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 firmly. Shift an automatic
transmission into PARK (P). Shift a manual
transmission into REVERSE (R). Turn the ignition
key to OFF. Lower both sunshades and rotate 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.
2. 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.

6. Then move the top rearward to its
fully
-stored position.
7. After the top is stored, apply one even push on the
center of the front edge (A) of the convertible top to
assure the top is fully retracted.
8. Close the storage compartment lid (C) by closing
with a swift, firm motion.
Raising the Convertible Top
1. Park on a level surface, set the parking brake firmly
and shift an automatic transmission into PARK (P).
Shift a manual transmission into REVERSE (R).
Lower both windows and sunshades 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.)

HIGH TRANS TEMP (Automatic Transmission
Only): You will hear four chimes when this message
is displayed. To acknowledge this warning, press the
RESET button. After you press the RESET button,
the message will be displayed every 10 minutes until the
condition changes. If you do not press RESET,
the message remains on the display until the
condition changes.
If the transmission fluid temperature rises above
270
F (132
C) or rises rapidly, this message is
displayed. The transmission may shift gears or apply the
torque converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can cause
the transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.If the HIGH TRANS TEMP message is displayed
during normal vehicle operation on flat roads,
your vehicle may need service. See your dealer for
an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message is
displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
an optional computer controlled system to assist the
driver in controlling the vehicle in difficult driving
conditions. You may feel or hear the system working
and see the ACTIVE HANDLING message displayed in
the DIC. This is normal when the system is operating.
