Keeps the brake applied after releasing the br ake pedal until the accelerator pedal is
pressed. You can use this system while the vehicle is temporarily stopped, such as
when you stop at a traffic light.

Activating the automatic brake hold system
on steep hills or slippery roads may still
allow the vehicle to move if you remove
your foot from the brake pedal.
If a vehicle unexpectedly moves, it may
cause a crash resulting in serious injury or
death.
Never activate the automatic brake hold
system or rely on it to keep a vehicle from
moving when stopped on a steep hill or
slippery roads.
3WARNING
Using the automatic brake hold system to
park the vehicle may result in the vehicle
unexpectedly moving.
If a vehicle moves unexpectedly, it may
cause a crash, resulting in serious injury or

Never leave the vehicle when braking is
temporarily kept by automatic brake hold

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d 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 distri bution 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 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 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.
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 your
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 turning the power
system on 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 may wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.

■When the system activates
At system’s earliest collision alert st age, you can change the distance (Long/
Normal /Short ) between vehicles at which alerts will come on through multi-
information display setting options.
2 List of customizable options P. 116
■Vibration alert on the steering wheel
When a potential coll ision to an oncoming detected vehicle is determined, the
system alerts you with rapid vibration on th e steering wheel, in addition to visual and
audible alerts.
u Take appropriate action to prevent a col lision (apply the brakes, operate the
steering wheel, etc.).
1 When the system activates
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.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS
TM Conditions and Limitations P. 434
The head-up warning uses a lens located at the front
end of the dashboard.
Do not cover the lens or spill any liquid on it.

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.
