FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the vehicle
is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.
Performance Shifting
If your vehicle has this feature, it can detect a
change in driving patterns. If you make an
aggressive driving maneuver, the vehicle’s
transaxle automatically shifts to the lowest possible
gear to maximize vehicle performance. The
vehicle will automatically return to normal operation
when you return to normal driving patterns.
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.

If the regular brake system warning light is also
on, you do not have anti-lock brakes and there is
a problem with your regular brakes. SeeBrake
System Warning Light on page 229.
The anti-lock brake system warning light should
come on briey when you turn the ignition key to
RUN. If the light does not come on then, have it
xed so it will be ready to warn you if there is a
problem.
Low Tire Pressure Warning Light
This light will come on
briey when you turn
the ignition to RUN.This light will also come on when one or more of
your tires are signicantly underinated.
A CHECK TIRE PRESSURE DIC message will
accompany the light, seeDIC Warnings and
Messages on page 246
Stop and check your tires as soon as it is safe
to do so. If underinated, inate to the proper
pressure. SeeTires on page 402for more
information.
This light will ash for approximately 60 seconds
and then turn on solid if a problem is detected with
the Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 414
for more information.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is
required. Malfunctions often will be indicated by
the system before any problem is apparent. This
may prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered
by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of
your vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 353.

allows the system to be turned on or off. Once
in this display, press the set/reset button to select
between ON or OFF. If you choose ON, the
system will be turned on. If you choose OFF,
the system will be turned off. The UFRPA system
automatically turns back on after each vehicle

the vehicle is shifted out of PARK (P), the DIC
will display the PARKING ASSIST OFF message
as a reminder that the system has been turned
off. SeeDIC Warnings and Messages on page 246
andUltrasonic Front and Rear Parking Assist
(UFRPA) on page 202for more information.
FRONT TIRES or REAR TIRES
The pressure for each tire can be viewed in the
DIC. The tire pressure will be shown in either
pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the
DIC displays FRONT TIRES PSI (kPa) LEFT ##
RIGHT ##. Press the vehicle information button
again until the DIC displays REAR TIRES
PSI (kPa) LEFT ## RIGHT ##.
If a low or high tire pressure condition is detected
by the system while driving, a message advising
you to check the pressure in a specic tire will
appear in the display. SeeInation - Tire Pressure
on page 411andDIC Warnings and Messages on
page 246for more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle.
If this consistently occurs, see your dealer for
service.

RELEARN TIRE POSITIONS
After rotating the tires or after replacing a tire or
sensor, the Tire Pressure Monitor (TPM) system
must re-learn the tire positions. To re-learn the tire
positions, seeTire Pressure Monitor System on
page 414. SeeTire Inspection and Rotation on
page 418andDIC Warnings and Messages on
page 246for more information.

pressure is low, the low tire pressure warning light
comes on. SeeLow Tire Pressure Warning Light on
page 231.
