If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to
the park position before turning off the
engine. If the wiper switch is left on and
the wipers freeze to the windshield,
damage to the wiper motor may occur
when the vehicle is restarted.
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You
might not see other vehicles or other
obstacles. To avoid sudden icing of the
windshield during freezing weather, warm
the windshield with the defroster before
and during windshield washer use.

Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Electronic
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 required.

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.
— Battery Charge Warning Light

This warning light will illuminate when the battery
is not charging properly. If it stays on while the
engine is running, there may be a malfunction with the charging system. Contact an authorized
dealer as soon as possible.

This indicates a possible problem with the
electrical system or a related component.
— Door Open Warning Light
This indicator will illuminate when a door is
ajar/open or not fully closed.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Electric Power Steering Fault Warning
Light
This warning light will turn on when there's a
fault with the Electric Power Steering (EPS)
system. Refer to “Electric Power Steering” in
“Starting And Operating” in the Owner’s
Manual for further information.
— Electronic Throttle Control (ETC)
Warning Light
This warning light will illuminate to indicate
a problem with the Electronic Throttle
Control (ETC) system. If a problem is
detected while the vehicle is running, 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 (P) position. The light should turn
off. If the light remains on with the vehicle
running, your vehicle will usually be drive -
able; 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 vehicle is
running, immediate 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 placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a
bulb check. If the light does not come on during
starting, have the system checked by an
authorized dealer.

WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.

Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended 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 Moni -
toring 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 tell -tale illuminates, 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 maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi
-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the instal -lation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be
compromised. Stop the vehicle, avoiding
sharp braking and steering. If a tire
puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.
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 operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using
an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealer to have your sensor
function checked.
