Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. 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 transaxle, so you
can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. 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 down. Release the shift
lever button. Then move the shift lever out of PARK (P),
being sure to press the shift lever button.

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 Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan 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.
Horn
Press at or near the horn symbols located on the steering
wheel pad to sound the horn.

2-52
Windshield Washer
PUSH:Press the paddle with the the word PUSH
and the washer symbol on it, located on top of the
multifunction lever, to spray washer fluid on the
windshield. The wipers will clear the windshield and
then either stop or return to the set speed.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Cruise Control
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
approximately 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.

2-53
Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the
multifunction lever and release it.
4. Take your foot off the accelerator pedal.Resuming a Set Speed
Suppose you set the cruise control at a desired speed and
then you apply the brake. This, of course, shuts off the
cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more
again, you can move the cruise control switch from ON
to R/A (Resume/Accelerate) briefly. You'll go right
back up to your chosen speed and stay there.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Push in the SET button, then release the button
and the accelerator pedal. You'll now cruise at the
higher speed.

Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. To increase your speed in
very small amounts, move the switch to R/A briefly
and then release it. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.
The accelerate feature will only work after you set the
cruise control speed by pushing the SET button.

2-54
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Push in the SET button until you reach the lower
speed you want, then release it.

To slow down in very small amounts, push the SET
button briefly. Each time you do this, you'll go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, the vehicle will slow
down to the cruise control speed you set earlier.Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. Of course, applying the brake
takes you out of cruise control. Many drivers find this to
be too much trouble and don't use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal,

or move the cruise switch to OFF.
Erasing Cruise Speed Memory
When you turn off the cruise control or the ignition, or
shift into PARK (P) or NEUTRAL (N), the cruise
control set speed memory is erased.

Daytime Running Lamps (DRL) /
Automatic Headlamp Control
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system will make your low
-beam headlamps
come on at a reduced brightness when the following
conditions are met:

The ignition is on,

the exterior lamps control is off,

the transaxle is not in PARK (P) and

the parking brake is released.When the DRL are on, only your low
-beam headlamps,
at a reduced brightness, will be on. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When it's dark enough outside, your headlamps will
change to full brightness. The other lamps that come on
with your headlamps will also come on.
When it's bright enough outside, the headlamps will go
out, and your low
-beam headlamps will change to the
reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your vehicle. The DRL will stay off until you shift out
of PARK (P) and release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Charging System Indicator 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 electrical 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.
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on when you turn the key to
RUN. If it doesn't come on then, have it fixed so it will
be ready to warn you if there's a problem.

2-81
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light will
come on when your engine
is started and may 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.
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.
