System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep the Rear Park Assist System operating prop-
erly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the Rear Park Assist System.
•When you turn off the Rear Park Assist System, the
instrument cluster will display “PARK ASSIST DIS-
ABLED.” Furthermore, once you turn off the Rear
Park Assist System, 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 the Rear Park Assist System is turned off,
a single chime will sound once per ignition cycle and
the instrument cluster will display “PARK ASSIST
DISABLED.”
•The Rear Park Assist System, when on, will MUTE the
radio when it is sounding a tone.
•If a Rear Park Assist 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 SYS-
TEM” and the LED in the Rear Park Assist switch will
illuminate. If this occurs, see your authorized dealer
for service.
CAUTION!
•The 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.(Continued)

5. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the PARK position. The light
should 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, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer. 6. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position, before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL 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 will
not require towing.
If the MIL flashes when the engine is running, serious
conditions may exist that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.

the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
13. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood. 14. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional 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 turned to the ON position, have the
light inspected by an authorized dealer.

20. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Indicator Light – If EquippedThe malfunction indicator for the Electronic
Stability Program (ESP) is combined with the
Brake Assist System (BAS). The yellow “ESP/
BAS Warning Light” in the instrument cluster
comes on when the ignition switch is turned to the ON
position. It should go out with the engine running. If the
“ESP/BAS Warning Light” comes on continuously with
the engine running, a malfunction has been detected in
either the ESP or the BAS system, or both. If this light
remains on after the several ignition cycles, and the
vehicle has been driven several miles/kilometers at
speeds greater than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE: The ESP Control System will make buzzing or
clicking sounds when it is active. This is normal; the sound will stop when the ESP becomes inactive following
a maneuver that caused the ESP activation.
21. SERV (Service) 4WD Indicator Light — If Equipped
The “SERV 4WD Indicator Light” will turn on
when the ignition key is turned to the ON
position and it will stay on for two seconds. If
the light stays on or turns on during driving, it
means that the 4WD system is not functioning properly
and that service is required.
22. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H, this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H, the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
208 UNDERSTANDING YOUR INSTRUMENT PANEL

If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.
23. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If 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 an authorized deal-
ership 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 an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
24. Transmission Temperature Indicator — If Equipped This light indicates that the transmission fluid
temperature is running hot. This may occur
with severe usage, such as trailer towing. If this
light turns on, safely pull over and stop the
vehicle. Then, shift the transmission into NEUTRAL and
run the engine at idle or faster until the light turns off. 25. Trip Odometer Button

26. 4WD Indicator — Vehicles Equipped with
Selec-TracII
This light alerts the driver that the vehicle is in
the full-time four-wheel drive auto mode. In
this mode, the system operates with a normal
torque split of 42% front axle and 58% rear axle.
It can redirect up to 100% of torque to the front or rear
axle, if necessary.
27. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer button” for additional
information.
NOTE: U.S. Federal regulations require upon transfer of
vehicle ownership, the seller certify the mileage the
vehicle has been driven. Therefore, if the odometer
reading is changed because of repair or replacement, be sure to keep a record of the reading before and after the
service so that the correct mileage can be determined.
Vehicle Warning Messages
When the appropriate conditions exist, messages such as
“door” (door ajar), “gATE” (liftgate ajar), “gLASS”
(flip-up glass ajar), “gASCAP” (fuel cap fault), “LoW
tirE” (low tire pressure), or “CHANgE OIL” will display
in the odometer.
LoW tirE
When the appropriate condition exists, the odometer
display will toggle between LoW and tirE for three
cycles.
NOTE:
If the instrument cluster is equipped with the
optional Electronic Vehicle Information Center (EVIC),
then most warnings will display in the EVIC.
