ParkSenseSystem Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense Rear Park
Assist system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the ParkSense Rear Park
Assist system.
•When you turn ParkSense off, the instrument cluster
will display “PARK ASSIST DISABLED.” Further-
more, once you turn ParkSense off, it remains off
until you turn it on again, even if you cycle the ignition
key.
•When you move the shift lever to the REVERSE
position and ParkSense is turned off, the instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSense system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM” and the
LED in the ParkSense switch will illuminate. If this
occurs after making sure the rear fascia/bumper is
clean and clear of snow, ice, mud, dirt, or other
obstruction, see your authorized dealer for service.
•Clean the ParkSense sensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt, or debris.
Failure to do so can result in ParkSense not working
properly. The ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
186 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Objects must not be within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the instrument cluster.
CAUTION!
•The ParkSenseRear Park Assist system is only a
parking aid and it is unable to recognize every
obstacle, including small obstacles. Parking curbs
might be temporarily detected or not detected at
all. Obstacles located above or below the sensors
will not be detected when they are in close prox-
imity.
(Continued)
CAUTION! (Continued)
•The vehicle must be driven slowly when using the
ParkSenseRear Park Assist system to be able to
stop in time when the obstacle is detected. It is
recommended that the driver looks over his/her
shoulder when using ParkSense.

NOTE:U.S. Federal regulations require that upon trans-
fer of vehicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has been
driven. If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero, and
a sticker must be placed in the door jamb stating what the
mileage was before the repair or service. It is a good idea
for you to make a record of the odometer reading before
the repair/service, so that you can be sure that it is
properly reset, or that the door jamb sticker is accurate if
the odometer must be reset at zero.

Rear Wheel Drive (RWD) / All Wheel Drive (AWD)
Displays (Base Cluster)
On vehicles equipped with a Base Instrument Cluster, the
odometer will display “2drivE” when the vehicle is in
Rear Wheel Drive (RWD), and “4drivE” when All Wheel
Drive (AWD) is activated.
If the odometer displays the “tCASE” warning message
after engine start up, or during driving, the AWD system
is not functioning properly and service is required.
NOTE:Vehicles equipped with Electronic Vehicle Infor-
mation Center (EVIC) will display “ALL WHEEL
DRIVE” and “REAR WHEEL DRIVE” when the appro-
priate condition exists. The EVIC will display “SERVICE
AWD SYSTEM” if the system is not functioning properly
and service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” for further information. gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
Lo tirE
When the appropriate tire pressure is low, the odometer
display will toggle between Lo and tirE for three cycles.

7. Tachometer
The red segments indicate the maximum permissible
engine revolutions per minute (RPM x 1000) for each gear
range. Ease up on the accelerator before reaching the red
area.
8. Engine Temperature Warning LightThis light will turn on and a single chime will
sound to warn of an overheated engine condition.
When this light turns on, the engine temperature
is critically hot. If the light turns on while driving, safely
pull over and stop the vehicle. The vehicle should be
turned OFF immediately and serviced as soon as pos-
sible. (Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information). 9. Anti-Lock Brake (ABS) Light — If Equipped
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is placed in the RUN position and may stay on for
as long as four seconds.
If the ABS Light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the Brake Warning Light is not on.
If the ABS Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock brakes. If the ABS Light does not turn on when
the ignition switch is placed in the RUN position, have
the light inspected by an authorized dealer.

12. Brake Warning LightThis light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction. In this case, the light will
remain on until the condition has been corrected.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level. The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H,” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H,” and you hear continuous chimes,
turn the engine OFF immediately and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintaining Your Vehicle”
and follow the warnings under the Cooling System

turn off. If the light remains lit with the engine running,
your vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.
Also, have the system checked by an authorized dealer if
the light does not come on during starting.
22. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
