Driving

Tire Pressure Monitoring System (TPMS) with Tire 
Fill Assist

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 MID.

1

Tire Pressure Monitoring System (TPMS) with Tire Fill Assist

Conditions such as low ambient temperature and 
altitude change directly affect tire pressure and can 
trigger the low tire pressure/TPMS indicator to come 
on.

If the Low Tire Pressure/TPMS Indicator 
Comes On or Blinks

 P. 646

Tire pressure checked and inflated in:

•

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.

516

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.

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.

Foot Brake

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. Depress the brake pedal 
and 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.

Anti-lock Brake System (ABS)

NOTICE

The ABS may not function correctly if you use a tire of 
the wrong size or type.

If the 

ABS

 indicator comes on while driving, there 

may be a problem with the system.
While normal braking will not be affected, there is a 
possibility that the ABS will not be operating. Have 
your vehicle checked by a dealer immediately.

The ABS is not designed for the purpose of reducing 
the time or distance it takes for a vehicle to stop: It is 
designed to limit brake lockup which can lead to 
skidding and loss of steering control.

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

•

You are driving on rough or uneven road surfaces, 
such as gravel or snow.

•

The tires are equipped with tire chains.

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 
power system has been turned on and while the 
vehicle 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.

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 

behind the emblem.

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.
