There are two heated seat switches that allow
the driver and passenger to operate the seats
independently. The controls for each seat are
located on a switch bank near the bottom
center of the instrument panel.
You can choose from HI, LO or OFF heat
settings. Amber indicator lights in each
switch indicate the level of heat in use. Two
indicator lights will illuminate for HI, one for
LO and none for OFF.Push the switch once to select HI-level heat-
ing. Push the switch a second time to select
LO-level heating. Push the switch a third
time to shut the heating elements OFF.
When the HI-level setting is selected, the
heater will provide a boosted heat level dur-
ing the initial stages of operation. Then, the
heat output will drop to the normal HI-level.
If the HI-level setting is selected, the system
will automatically switch to LO-level after
approximately 30 minutes of continuous op-
eration. At that time, the number of illumi-
nated LEDs changes from two to one, indicat-
ing the change. The LO-level setting will turn
OFF automatically after approximately
30 minutes.
NOTE:
When a heat setting is selected, heat will be
felt within two to five minutes.

tion or other physical condition must
exercise care when using the seat
heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
• Do not place anything on the seat or
seatback that insulates against heat,
such as a blanket or cushion. This may
cause the seat heater to overheat. Sit-
ting in a seat that has been overheated
could cause serious burns due to the
increased surface temperature of the
seat.

hicle” in “Starting And Operating” for fur-
ther information)
• Oil Change Required (with a single chime)
• ECO (Fuel Saver Indicator) — if equipped
Gear Shift Indicator (GSI) — If Equipped
The Gear Shift Indicator (GSI) system is en-
abled on vehicles with a manual transmis-
sion, or when a vehicle with an automatic
transmission is in manual shift mode. The
GSI provides the driver with a visual indica-
tion when the recommended gear shift point
has been reached. This indication notifies
the driver that changing gear will allow a
reduction in fuel consumption. When the up
shift indicator is shown on the display, the
GSI is advising the driver to engage a higher
gear. When the down shift indicator is shown
on the display, the GSI is advising the driver
to engage a lower gear.
The GSI indicator remains illuminated until
the driver changes gear, or the driving condi-
tions return to a situation where changing gear
is not required to improve fuel consumption.
Oil Change Required
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change
Required” message will display in the instru-
ment cluster display for approximately
10 seconds after a single chime has sounded
to indicate the next scheduled oil change
interval. The engine oil change indicator sys-
tem is duty cycle based, which means the
engine oil change interval may fluctuate de-
pendent upon your personal driving style.
Unless reset, this message will continue to
display each time you turn the ignition switch
to the ON position. To turn off the message
temporarily, push and release theMENUbut-
ton. To reset the oil change indicator system
(after performing the scheduled mainte-
nance), perform the following procedure:
WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicativeand precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first

— Brake Warning Light
This 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.
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 hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied 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 conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.

proaches "H," this indicator will illuminate
and a single chime will sound.
— Electronic Throttle Control (ETC)
Warning Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is run-
ning, the light will either stay on or flash
depending on the nature of the problem.
Cycle the ignition when the vehicle is safely
and completely stopped and the transmission
is placed in the PARK position. The light
should turn off. If the light remains on with
the vehicle running, your vehicle will usually
be drivable; however, see an authorized
dealer for service as soon as possible.
NOTE:
This light may turn on if the accelerator and
brake pedals are pressed at the same time.
If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing.
The light will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-tion and remain on briefly as a bulb check. If
the light does not come on during starting,

Light
This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition is placed in the ON/RUN or ACC/ON/
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 as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warn-
ing Light is not also on.If the ABS light does not turn on when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position, have the brake system in-
spected by an authorized dealer.
