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 an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.
2Brake Assist System P. 493
2 Anti-lock Brake System (ABS) P. 492
■Brake squeal
To satisfy the performance under a wide range of driving conditions, a high
performance braking system is equipped on your vehicle. You may hear the brake
squeal under certain conditions, such as vehicle speed, deceleration, humidity, and
so on. This is not a malfunction.
■Foot Brake1 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 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 vibr ation 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 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, a nd helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
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. Depress the brake
pedal and keep holding the pedal firmly dow n. 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 yo u 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 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 a tire of
the incorrect 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 wi ll 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 lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur 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
engine has been started 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.

Maintenance
Opening the Hood
1. Park the vehicle on a level surface, and set
the parking brake.
2. Pull the hood release handle under the
driver’s side lower corner of the dashboard.
u The hood will pop up slightly.
3. Push the hood latch lever (located under
the front edge of the hood to the center) to
the side and raise the hood. Once you have
raised the hood slightly, you can release the
lever.
4. Lift the hood up most of the way.

rest of the way and hold it up.
When closing, lower it to approximately 12
inches (30 cm), then pr ess down firmly with
your hands.1 Opening the Hood
NOTICE
Do not open the hood when the wiper arms are
raised. The hood will strike the wipers, resulting in
possible damage to the hood and/or the wipers.
NOTICE
Do not press the engine cover forcibly. This may
damage the engine cover and component parts.
When closing the hood, check that the hood is
securely latchedM
If the hood latch lever moves stiffly, or if you can
open the hood without lifti ng the lever, the latch
mechanism should be cl eaned and lubricatedM
Do not open the hood while the Auto Idle Stop
function is activated.
