Shifting Out of PARK (P)
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. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
Your vehicle has a Brake-Transaxle Shift Interlock
(BTSI). You must fully apply your regular brakes before
you can shift from PARK (P) when the ignition is in
RUN. See ªAutomatic Transaxle Operationº in
the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
while keeping the brake pedal pushed down. Release the
shift lever button if you have a console shift. Then move
the shift lever out of PARK (P), being sure to press the
shift lever button if you have a console shift.If you ever hold the brake pedal down but still can't
shift out of PARK (P) with column shift, try this:
1. Turn the ignition key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and shift to the drive gear you want.
5. Have the vehicle fixed as soon as you can.
For vehicles equipped with the console shift lever, see
ªShift Lock Releaseº in the Index.
Shift Lock Release
This vehicle is equipped with an electric Shift Lock
Release system. The shift lock release is designed to:

Prevent ignition key removal unless the shift lever is
in PARK (P) (with the shift knob button fully
released if console shift), and

prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than OFF or
LOCK. The shift lock release is always functional
except in the case of a dead or low voltage
(less than 9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there are two override access slots that will
allow you to override the shift lock release.

Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things that
can burn.
Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving
over high points on the road or over
road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.

Running Your Engine While
You're Parked
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.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.

2-49 Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on the
accelerator. This can really help on long trips. Cruise control
does not work at speeds below about 25 mph (40 km/h).
When you apply the brakes, the cruise control shuts off.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
If your vehicle is in cruise control when the traction
control system on the 3800 Supercharged V6 engine, or
the enhanced traction system on the 3100 V6 and
3800 V6 engine begins to limit wheel spin, the cruise
control will automatically disengage. (See ªTraction
Control Systemº or ªEnhanced Traction Systemº in the
Index.) When road conditions allow you to safely use it
again, you may turn the cruise control back on.

2-69 Speedometer/Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). The
odometer shows how far the vehicle has been driven in
either miles (used in the United States) or in kilometers
(used in Canada).
The vehicle has a tamper
-resistant odometer. If you see
silver lines between the numbers, you'll know someone
has probably tampered with it and the numbers may not
be correct.
You may wonder what happens if the vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can't, then it will be set at zero and a label must be
put on the driver's door to show the old mileage reading
when the new odometer was installed.
Trip Odometer
The trip odometer tells how far you have driven since
you last reset it. To set it to zero, press the RESET
button on the right side of the instrument cluster.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle may also have a driver information system
that works along with the warning lights and gages.
See ªDriver Information Systemº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 70 seconds, or
until the driver's seatbelt
is buckled.
If the driver's belt is already buckled, neither the chime
nor the light will come on.

2-71 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows SRS AIR BAG. The system checks
the air bag's electrical system for malfunctions. The
light tells you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see ªAir Bagº in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition, as
a check to show you it's
working. Then it will
go out.
If it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose drive belt or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

2-73 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay on
for three seconds.
That's normal.
If the anti
-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you're driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning Light
(3800 Supercharged V6 Engine Only)
The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the TCS button
located on the far right hand side of the Driver
Information Center, the warning light will come on and
stay on. To turn the system back on, press the button
again. The warning light should go off. (See ªTraction
Control Systemº in the Index for more information.)

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
