uuBraking uBrake System
390
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress th e brake pedal hard in an emergency
situation. The anti-lock brake system (ABS ) helps you retain steering control when
braking very hard.

■Foot Brake1Foot 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 me tallic 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 deal er. 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 brak e pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal 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 conf use drivers behind you.

uuBraking uAnti-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 distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you w ill 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.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-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 ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

Brake Assist System
Designed to assist the driver by generati ng greater braking force when you depress
the brake pedal hard during emergency braking.
■Brake assist system operation
Press the brake pedal firmly for more powerful braking.
When brake assist operates, the pedal ma y wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Continued
Driving
Collision Mitigation Braking SystemTM (CMBSTM)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM 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.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:
2 CMBS
TM Conditions and Limitations P. 397
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 352
The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions. 2 CMBS
TM Conditions and Limitations P. 397
The system starts monitoring the roadway ah ead 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.

the stages before initiating the last stage.
