Tire Pressure Monitoring System (TPMS) with Tire Fill Assist

Driving

Tire Pressure Monitoring System (TPMS) with Tire

Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the multi-information display.

Tire Pressure Monitoring System (TPMS) with Tire Fill Assist

Conditions such as low ambient temperature and

trigger the low tire pressure/TPMS indicator to come
on.

Warm weather can become under-inflated in
colder weather.

•

Cold weather can become over-inflated in warmer
weather.

The low tire pressure/TPMS indicator will not come
on as a result of over inflation.

The TPMS audibly and visually informs you of
changes in tire pressure of the individual tire that you
are adjusting using audible and visual indications.

If a change in tire pressure has been significant, the
system beeps and the hazard lights flash continuously
for five seconds when the specified tire pressure is
reached. Stop filling the tire.

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

Driving

Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation

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.

Accordingly, 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 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.

409

uu

When Driving

u

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

Driving

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 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 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.

Blind spot information System

*

Driving

Blind spot information System

*

Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”

When the system detects vehicles approaching from behind in adjacent lanes, the
appropriate indicator comes on for a few seconds, providing assistance when you
change lanes.

Important Safety Reminder

Like all assistance systems, blind spot information
system has limitations. Over reliance on blind spot
information system may result in a collision.

The blind spot information system alert indicator may
not come on under the following conditions:

•

A vehicle does not stay in the alert zone for more
than two seconds.

•

A vehicle is parked in a side lane.

•

The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).

•

An object not detected by the radar sensors
approaches or passes your vehicle.

•

A vehicle running in the adjacent lane is a
motorcycle or other small vehicle.

3

WARNING

Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on the blind spot
information system when changing lanes.

Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

For a proper blind spot information system operation:

•

Always keep the rear bumper corner area clean.

•

Do not cover the rear bumper corner area with
labels or stickers of any kind.

•

Take your vehicle to a dealer if you need the rear
bumper corner area or the radar sensors to be
repaired, or the rear bumper corner area is strongly
impacted.
