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.

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.

High Voltage Battery

Driving

High Voltage Battery

The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an extended period of time, the battery level may
get low. Keeping your vehicle’s battery level low can shorten the battery life. To
maintain the battery, drive your vehicle for more than 30 minutes to recharge the
battery at least once every three months.
To help maintain the battery life, when parking under the direct sunlight during
summer, try find a shaded area.

Brake System

302

Driving

Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The anti-lock brake system (ABS) helps you retain steering
control when braking very hard.

Foot Brake

1

Foot Brake

Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.

If you hear a continuous metallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a dealer. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibration of the brake pads against
the rotating brake disc.

Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply regenerative braking by taking
your foot off the accelerator pedal and downshifting
to a lower gear.

Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also confuse drivers behind you.

Anti-lock Brake System (ABS)

Driving

Anti-lock Brake System (ABS)

Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.

The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.

You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pedal. This is sometimes referred to as
“stomp and steer.”

■

ABS operation

You may hear an operating noise when the ABS is working. Keep holding the pedal
firmly down. On dry pavement, you will need to press on the brake pedal very hard
before the ABS activates. However, you may feel the ABS activate immediately if you
are trying to stop on snow or ice.

ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.

When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

■

ABS

Anti-lock Brake System (ABS)

NOTICE

The ABS may not function correctly if you use an
incorrect tire type and size.

When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.

The ABS does not reduce the time or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.

In the following cases, your vehicle may need more
stopping distance than a vehicle without the ABS:

•

When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.

•

When snow chains are installed.

The following may be observed with the ABS system:

•

Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while vehicle is
accelerates.

•

Brake pedal and/or the vehicle body vibration when
ABS activates.

These vibrations and sounds are normal to ABS
systems and are no cause for concern.

Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBS

TM

is designed to alert you when a

potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.

Important Safety Reminder
The CMBS

TM

is designed to reduce the severity of an

unavoidable collision. It does not prevent a collision
nor stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.

The CMBS

TM

may not activate or may not detect a

vehicle in front of your vehicle under certain
conditions:

camera equipped with this system.

1

How the system works

Rapid vibrations on the steering wheel alert you
when your vehicle speed is between 19 and 62 mph
(30 and 100 km/h) with an oncoming vehicle
detected in front of you.

When the CMBS

TM

activates, it may automatically

apply the brake. It will be canceled when your vehicle
stops or a potential collision is not determined.

The system starts monitoring the roadway ahead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.

The radar sensor is
in the front grille.

The CMBS

TM

activates when:

●

The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.

●

Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you.

The camera is
located behind the
rearview mirror.
