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
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're pulling a trailer, see ªTowing a Trailerº in
the Index.
Horn
Press the pad in the center of the steering wheel to sound
the horn.

Tilt Wheel (If Equipped)
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can also raise it to the
highest level to give your legs more room when you
enter and exit your vehicle.
The tilt steering wheel lever
is located on the lower left
side of the column.
To tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to a comfortable level,
then release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

Turn and Lane Change Signals

Headlamp High/Low
-Beam Changer

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)

2-34 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 your 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.

2-38 Headlamps On Reminder
A tone will sound when the headlamps are turned on and
the key is turned to OFF, LOCK or ACCESSORY. If
you need to use the headlamps when the key is turned to
OFF, LOCK or ACCESSORY, the buzzer can be turned
off by turning the thumbwheel next to the exterior lamps
control all the way down.
Daytime Running Lamps
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.The DRL system will make your headlamps come on
at a reduced brightness when the following conditions
are met:

the ignition is on,

the exterior lamps control is off and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light is a
reminder to turn the exterior lamps control to the
headlamp position on. The other lamps that come on
with your headlamps will also come on.
When you turn off the exterior lamps control, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Interior Lamps
Instrument Panel Brightness Control
This feature controls the brightness of the instrument
panel lights.
The thumbwheel for this feature is located to the right of
the exterior lamps control.
Turn the thumbwheel up to brighten the lights or down
to dim them.
When the thumbwheel is moved to the first position, the
radio display and transmission selection display will go
to full intensity. The instrument panel cluster will be
dimly lit.
Moving the thumbwheel up to the next position will
activate the interior dome lamps
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When a door is opened, the dome lamps will come on if
the DOME OVERRIDE button is in the out position.
When all the doors are closed, the lamps will stay on for
a short period of time and will then go out. If the DOME
OVERRIDE button is pressed in, the lamps will not
come on.
Front Reading Lamps (If Equipped)
If your vehicle has reading
lamps, press the button
located next to each lamp
to turn the lamp on or off.
The lamps can be adjusted
to point in the direction
you want.

2-40 Dome Lamp
The dome lamp will come on when you open a door.
You can also turn the dome lamp on by turning the
thumbwheel, located next to the exterior lamps control,
all the way up to the second notch. In this position, the
dome lamp will remain on whether a door is opened
or closed.
You can use the DOME OVERRIDE button, located
near the exterior lamp control, to set the dome lamps to
come on automatically when a door is opened, or to
remain off. To turn the lamps off, press the button into
the in position, the dome lamps will remain off when a
door is open. To return the lamps to automatic operation,
press the button again and return it to the out position.
With the button in this position, the dome lamps will
come on when you open a door.
Cargo Lamp (If Equipped)
Press the top of the switch
to turn the cargo lamp on.
Press the bottom of the
switch to turn it off.
The dome lamp must be on and one of the doors open
for the cargo lamp to work.

Let's say the road is wet and you're driving safely.
Suddenly, an animal jumps out in front of you.
You slam on the brakes and continue braking.
Here's what happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each
front wheel and at both rear wheels.The anti
-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
This can help you steer around the obstacle while
braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

4-9
Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned
on the news happen on curves. Here's why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While you're
in a curve, speed is the one factor you can control.
