uuWhen Driving uTire Pressure Monitoring System (TPMS)
Driving
To select the tire pressure monitor, set the power
mode to ON, and roll the right selector wheel
until you see the tire pressure screen.The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).
Tire Pressures Low /CHECK TIRE PRESSURE
is displayed when a tire has significantly low
pressure. The specific tire is displayed on the
screen.
■
Tire Pressure Monitor
1 Tire Pressure Monitor
The pressure displayed on the multi-information
display can be slightly diffe rent from the actual
pressure as measured by a gauge. If there is a
significant difference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the multi-information display do not go off after
you have inflated the tire to the specified pressure,
have the system checked by a dealer.
Tire Pressure Monitor Problem /CHECK TPMS
SYSTEM may appear if you drive with the compact
spare tire
*, or there is a problem with the TPMS.
If a change in tire pressure has been significant the
beeper and hazard warning lights may do lay in
sounding and flashing when the specific tire pressure
is reached.

BrakingBrake SystemUse the parking brake to keep the vehicle stationary when parked. You can
manually apply and release, or automatically release it.■Manual operations
Use the electric parking brake switch to apply or release the brake. Manually
releasing the parking brake using the switch helps your vehicle start slowly and
smoothly when facing down hill on steep hills.
■To apply manually
Pull the electric parking brake switch up gently
and securely. u The electric parking brake indicator
comes on.

Parking Brake
1Parking Brake
You may hear the elect ric parking brake system
motor operating from the rear wheel area when you
apply or release the parking brake, or set the power
mode to OFF. This is normal.
The brake pedal may slightly move due to the electric
parking brake system operation when you apply or
release the parking brake. This is normal.
You cannot apply or release the parking brake if the
battery goes dead. 2 Jump Starting P. 498
If you pull up the electric parking brake switch while
driving, all four brakes get applied, not the parking
brake.
In the following situations, the parking brake
automatically operates.•When the vehicle stops more than 10 minutes
while ACC with LSF
* is activated.
•When the driver’s seat belt is unfastened while your
vehicle is stopped automatically by ACC with LSF
*.
•When the engine is turned off while ACC with LSF
*
is activated.
•When the vehicle stops with the automatic brake
hold system activated for more than 10 minutes.•When the driver’s seat belt is unfastened while
your vehicle is stopped and brake hold is applied.•When the engine is turned off while brake hold is
applied.•When there is a problem with the Brake Hold
System.

uuBraking uBrake System
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.2 Brake Assist System P. 403
2 Anti-lock Brake System (ABS) P. 402■
Foot Brake
1Foot 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, the brake pads need to be
replaced. Have your vehicle checked by a dealer.
Constantly using the brake 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 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.

Keeps the brake applied after releasing the brake 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.■

WARNING
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 unexpec tedly 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.

WARNING
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
death.
Never leave the vehicle when braking is
temporarily kept by automatic brake hold
and always park the vehic le by putting the
transmission in

brake.
■Turning on the system
Fasten your seat belt
properly, then start the
engine. Press the

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)Helps prevent the wheels from locking up, and help s 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
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 under 6 mph (10 km/h), the ABS stops.■
ABS
1 Anti-lock Brake System (ABS)NOTICEThe 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 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 tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediatel y after starting the engine or
while driving. This is normal.

uuBraking uBrake Assist System
Driving
Brake Assist SystemDesigned to assist the driver by generating 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.■
