CAUTION!
²The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
²The vehicle must be driven slowly when using the
Rear 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 the Rear Park Assist System.
²Clean the Rear Park Assist Sensors with water, car
wash soap, and a soft cloth. Do not use rough or
hard cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. (Refer to
ªTire Inflation Pressuresº under ªTires Ð General
Informationº and to ªTire Pressure Monitor System
(TPMS)º in Section 5 of this manual for more
information).5. Electronic Throttle Control (ETC) Warning Light Ð
If Equipped
This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected, the light will turn on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable
and not need towing, however see your authorized
dealer for service as soon as possible.
If the light is flashing when the engine is running, you
may experience power loss, an elevated/rough idle, and
increased brake pedal effort, and your vehicle may
require towing. Immediate service is required.
The light will turn on when the ignition switch is first
turned ON, and remain on briefly as a bulb check. This is
normal. If the light does not turn on during starting, have
the system checked by an authorized dealer.

6. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will turn on when the key is in the ON position before
engine start. If the light does not turn on when turning
the key from LOCK or ACC to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may turn on the light after engine
start. The vehicle should be serviced if the light stays on
through several of your typical driving cycles. In most
situations, the vehicle will drive normally and it will not
require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalyticconverter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 399 for more
information.)
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.

NOTE:As the coolant temperature gauge approaches
9H,9this indicator will illuminate and a single chime will
sound. Further overheating will cause the temperature
gauge to pass9H.9In this case, the indicator will flash
continuously and a continuous chime will sound, until
the engine is allowed to cool.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads ªH,º
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 ªH,º 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, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure Cap
paragraph.
23. Coolant Temperature Gauge
The temperature gauge indicates engine coolant tem-
perature. Any reading within the normal range indicates
that the cooling system is operating satisfactorily. The
