Automatic Transaxle Operation
There are several
different positions for
your shift lever.
PARK (P): This position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.CAUTION:
It is 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 have 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).
See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº
in the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle shift
lock control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition key is in RUN.

2-28
AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than approximately 35 mph (55 km/h),
push your accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads,

when towing a trailer, so there is less shifting
between gears, or

when going down a steep hill.SECOND (2): This position gives you more power
but lower fuel economy than AUTOMATIC
OVERDRIVE (D) or THIRD (3). You can use
SECOND (2) on hills. It can help control your speed
as you go down steep mountain roads, but then you
would also want to use your brakes off and on.
FIRST (1): This position gives you even more power but
lower fuel economy than SECOND (2). You can use it on
very steep hills, or in deep snow or mud. If the selector
lever is put in FIRST (1), the transaxle won't shift into
FIRST (1) until the vehicle is going slowly enough.
NOTICE:
If your front wheels can't turn, don't try to drive.
This might happen if you were stuck in very deep
sand or mud or were up against a solid object.
You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK (P)
to hold your vehicle in position on a hill.

2-29
Parking Brake
Your vehicle has a PUSH
TO RELEASE parking
brake. To set the parking
brake, hold the regular
brake pedal down with
your right foot. Push down
the parking brake pedal
with your left foot.
If the ignition is on, the brake system warning light
will come on while the parking brake is set and a single
chime will be heard.To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal with your left foot. This will release the
parking brake pedal. When you lift your left foot, the
parking brake pedal will follow it to the release position.
If you try to drive approximately 20 feet (6.1 m) with
the parking brake on, the brake light stays on and a
chime sounds until you release the parking brake.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and are parking on any hill,
see ªTowing a Trailerº in the Index. That section
shows what to do first to keep the trailer from moving.

2-41 Windshield Washer
The lever on the right side of your steering column also
controls your windshield washer. To spray washer fluid
on the windshield, push the button on the end of the
lever. The wipers will clear the window and then either
stop or return to your preset speed. For more washer
cycles, push and hold the button.
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.
Ice build up can block washer nozzles. Remove ice for
proper operation.
If the fluid level in the windshield washer bottle is low,
the message LOW WASHER FLUID will appear in the
Driver Information Center. See ªWindshield Washer
Fluidº in the Index.
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 is helpful 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.

2-70
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 you try to drive off with the parking brake set,
a chime will also come on until you release the parking
brake. If the light stays on after your parking brake is
fully released, it means you have a brake problem.
A PARK BRAKE SET message will be displayed on
the Driver Information Center (DIC) while the park
brake is set and the vehicle is moving. The message
will not come on if the transaxle is in PARK (P).
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if
the light comes 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 regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is also
on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.
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.

2-71 Traction Control System Warning Light
This warning light should
come on briefly as you
start the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is on,
the system will not limit wheel spin. Adjust your
driving accordingly.
The traction control system warning light may come
on for the following reasons:

If you turn the system off by pressing the TC button
located on the center console, 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 is affected by an
engine
-related problem, the system will turn off
and the warning light will come on.
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.
Traction Control System Active Light
When your traction control
system is limiting wheel
spin, this light will come on.
Slippery road conditions may exist if the traction
control system active light comes on, so adjust your
driving accordingly.
The light will stay on for a few seconds after the traction
control system stops limiting wheel spin.

4-6
Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you're driving on snow or ice, it's easy
to ask more of those control systems than the tires and
road can provide. That means you can lose control of your
vehicle. Also see ªTraction Control Systemº in the Index.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up
your foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second.
But that's only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part. So do alcohol, drugs and
frustration. But even in 3/4 of a second, a vehicle
moving at 60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly with
the surface of the road (whether it's pavement or gravel);
the condition of the road (wet, dry, icy); tire tread; the
condition of your brakes; the weight of the vehicle and
the amount of brake force applied.

4-7
Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and the
brake pedal will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº
in the Index.
