Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Do not drive at any one constant speed, fast
or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 315for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is in all
the way. If none of this works, then your vehicle
needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACCESSORY or RUN position with the engine
off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the key is
in the ignition. SeeDIC Warnings and Messages on
page 221for more information.

Parking Brake
The parking brake pedal
is located to the left of
the regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the
parking brake pedal down with your left foot.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come
on. If it does not, you need to have your vehicle
serviced.A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light will
come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 201for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push
the parking brake pedal down with your left
foot. When you lift your left foot, the parking
brake pedal will follow it to the released position.
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 are parking on any
hill, seeTowing a Trailer on page 315.
122

Torque Lock
If you are parking on a hill and you do not 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 nd it 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 you
leave the driver’s seat. To nd out how, seeShifting
Into Park (P) on page 123.
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 have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is RUN. SeeAutomatic Transaxle
Operation on page 119.
The shift lock control system is designed to do the
following:
Prevent the ignition key from being removed
unless the shift lever is in PARK (P).
Prevent movement of the console shift lever
out of PARK (P) unless the ignition is in a
position other than OFF.
The shift lock control system is always functional
except in the case of a dead battery or low
voltage (less than 9 V) battery.
If you cannot shift out of PARK (P), ease the
pressure on the shift lever. Push the shift lever
all the way into PARK (P) as you maintain
brake application. Then move the shift lever into
the gear you want.
If you are still having a problem shifting, then have
your vehicle serviced soon.
