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.

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, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
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.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

Brake Assist System
Designed 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 ma y wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.

Emergency Engine Stop
If you cannot stop the engine by pressing the ENGINE START/STOP button, do
either of the following operations:
• Press and hold the ENGINE START/STOP button for three seconds.
• Firmly press the ENGINE START/STOP button three times.
• The steering wheel will not lock. The po wer mode changes to VEHICLE OFF with
the shift lever in
(P, and to ACCESSORY with the shift lever in any position other
than
(P.
• Because turning off the engine also disables the power assist the engine provides
to the steering and braking systems, it w ill require significantly more physical
effort and time to steer and slow the ve hicle. Downshift gears and use both feet
on the brake pedal, if necessary, to slow the vehicle and stop immediately in a
safe place.
1 Emergency Engine Stop
Do not press the button while driving unless it is
absolutely necessary for th e engine to be switched
off.
