uuBrakinguBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A power assist helps
reduce the effort needed on the brake pedal. 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. 223

■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 metallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the 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. With manual transmission use a lower
gear for greater engine braking.
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.

uuBrakinguABS (Anti-lock Brake System)
Driving
ABS (Anti-lock Brake System)
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
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.
■ABS1ABS (Anti-lock Brake System)
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 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.

Auto Idle Stop
To help maximize fuel economy, Auto Idle Stop shuts off the engine when the
vehicle comes to a stop, depending on environmental and vehicle operating
conditions. The AUTO STOP indicator blinks at this time.The engine then restarts once the vehicle is
about to move again, and the indicator goes off.
If the driver’s door is opened while the
indicator is blinking, a buzzer sounds to notify
you that the Auto Idle Stop function is in operation.

Auto Idle Stop
To help maximize fuel economy, the engine automatically stops when the vehicle
comes to a stop, depending on environmental and vehicle operating conditions. The
AUTO STOP indicator blinks at this time. The engine then restarts once the vehicle is
about to move again when you depress the clutch pedal fully, and the indicator goes
off.
If the driver’s door is opened while the
indicator is blinking, a buzzer sounds to notify
you that the Auto Idle Stop function is in operation.

If the Auto Idle Stop operating time lasts long enough
to lower the 12 volt battery charge or the IMA battery charge, the engine may not restart automatically.
