Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected, the cause
should be located and corrected immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

Tire Pressure Monitoring System (TPMS) Warning Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is displayed to indicate that the tire pressure is
lower than the recommended value and/or that slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immedi-
ately using the dedicated tire repair kit and contact
your authorized dealer as soon as possible.
Each 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. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.
218 UNDERSTANDING YOUR INSTRUMENT PANEL

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain 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 malfunc-
tion 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 illuminated. 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 installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale afterreplacing 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!
The TPMS has been optimized for the original equip-
ment 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 equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.4

WARNING!(Continued)
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning 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 “Anti-Lock Brake Warning Light” remains on or
comes 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 sys-
tem will continue to operate normally if the “Brake System
Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warn-
ing Light” does not come on when the ignition switch is
turned to the ON position, have the light repaired as soon
as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem detects an emergency braking situation by sensing the
rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the anti-lock
brake system (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure
during the stopping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be

320 STARTING AND OPERATING

Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
