How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil used in the vehicle, and some other
things. Instead of trying to list everything here, contact
your dealer in the area where the vehicle will be parking.
The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
The shift lever for the automatic transmission is on the
steering column.
The ignition positions are displayed on the instrument
panel cluster and will indicate the gear the vehicle is in.Maximum engine speed is limited on the automatic
transaxle when the vehicle is in PARK (P) or
NEUTRAL (N) to protect driveline components from
improper operation.
There are several different positions for the shift lever.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not 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 will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) on
page 2-26. If you are pulling a trailer, see
Towing a Trailer on page 4-39.
2-22

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.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. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
A warning chime will sound if the parking brake is set,
the ignition is on and the shift lever is not in PARK (P) or
NEUTRAL (N).
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and parking on any hill, see
Towing a Trailer on page 4-39. That section shows what
to do rst to keep the trailer from moving.
2-25

Shifting Into Park (P)
{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 rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-39.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.
2. Move the shift lever into PARK (P) like this:
Pull the shift lever toward you.
2-26

Move the shift lever up as far as it will go.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, the vehicle is in PARK (P).
Leaving Your Vehicle With the Engine
Running
{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 rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If the vehicle is left with the engine running, be sure it is
in PARK (P) and the parking brake is rmly set before
you leave it. After you have moved the shift lever
into PARK (P), hold the regular brake pedal down. Then,
see if you can move the shift lever out of PARK (P). If
you can, it means that the shift lever was not fully locked
into PARK (P).
2-27

Torque Lock
If parking the vehicle on a hill and the transaxle is not
shifted into PARK (P) properly, the weight of the vehicle
may put too much force on the parking pawl in the
transaxle. It might be difficult to pull the shift lever out of
PARK (P). This is called torque lock. To prevent
torque lock, set the parking brake and then shift into
PARK (P) properly before leaving the driver’s seat. To
nd out how, seeShifting Into Park (P) on page 2-26.
When you are ready to drive, move the shift lever out of
PARK (P) before releasing the parking brake.
If torque lock does occur, another vehicle might have to
push yours a little uphill. This takes some of the
pressure off the parking pawl in the transaxle, enabling
the shift lever to be moved out of PARK (P).
Shifting Out of Park (P)
The vehicle has an automatic transaxle shiftlock control
system which locks the shift lever in PARK (P) when
the ignition is in the OFF position. The regular brakes
have to be fully applied before the vehicle can be shifted
from PARK (P) when the ignition is in RUN. See
Automatic Transaxle Operation on page 2-22.
If the vehicle cannot be shifted out of PARK (P),
ease pressure on the shift lever and push the shift
lever all the way up into PARK (P) as brake application
is maintained. Then move the shift lever into the
desired gear.
If the brake pedal is held down but still cannot be
shifted out of PARK (P), try this:
1. Turn the ignition key to ACCESSORY. There is no
shift interlock in this key position.
2. Apply and hold the brake until the end of Step 4.
3. Shift the transaxle to NEUTRAL (N).
4. Start the vehicle and then shift to the desired gear.
5. Have the system xed as soon as possible.

Running Your Engine While You
Are Parked
It is 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
Engine Exhaust on page 2-29.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control 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.
SeeWinter Driving on page 4-26.
{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 rmly set. Your vehicle can
roll. Do not 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 will not move, even
when you are 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 will not
move. SeeShifting Into Park (P) on page 2-26.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-39.

Daytime Running Lamps/Automatic
Headlamp System
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. Daytime running
lamps are required to function at all times on all
vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, the front turn signal lamps also
will be on. The headlamps, taillamps, sidemarker
and other lamps will not be on. The instrument panel
will not be lit up either.When it is dark enough outside, the front turn signal
lamps will turn off and the vehicle’s headlamps
and parking lamps will turn on. The other lamps that
come on with the headlamps will also come on.
When it is bright enough outside, the headlamps will go
off and the front turn signal lamps will come on.
To idle the vehicle with the DRL and automatic
headlamp control off, set the parking brake while the
ignition is in OFF or LOCK. Then start the vehicle. The
DRL, headlamps and parking lamps will stay off until
the parking brake is released.
To turn off the automatic headlamp feature when it is
dark outside, move the exterior lamps control to
the parking lamp position. The parking lamps will remain
illuminated and the headlamps will turn off.
As with any vehicle, the regular headlamp system
should be turned on when needed.

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the ignition key
is turned to RUN. If it does not come on then, have
it xed so it will be ready to warn you if there is a
problem.When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while the vehicle is being driven,
pull off the road and stop carefully. The pedal may
be harder to push. or it may go closer to the oor. It may
take longer to stop. If the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 4-31.
{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 have pulled off the road and
stopped carefully, have the vehicle towed for
service. United StatesCanada

Enhanced Traction System Warning
Light
If the vehicle has the
Enhanced Traction
System, (ETS) the warning
light may come on for
the following reasons:
When the vehicle is shifted to SECOND (2) or
FIRST (1). To turn the system back on, shift
to THIRD (3) or AUTOMATIC OVERDRIVE (
X).
SeeEnhanced Traction System (ETS) on page 4-9.
If the vehicle needs service. Adjust your driving
accordingly.
When the parking brake is set with the engine
running, and the parking brake does not
release fully.
After the parking brake is fully released and the
transaxle shift lever is in any position other
than FIRST (1) or SECOND (2). This means there
is a problem with the system.
If an engine-related problem affects the ETS and
turns the system off.
When the ETS warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
Low Traction Light
If the vehicle has the
Enhanced Traction System
(ETS), this light will
come on when the system
is limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the
low traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds after
the ETS stops limiting wheel spin. SeeEnhanced
Traction System (ETS) on page 4-9.
The low traction light also comes on briey when the
ignition key is turned to RUN. If the light does not come
on then, have it xed so it will function properly to
indicate when the Enhanced Traction System is active.
