Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has 12-volt battery, no matter
which position the power mode is in.
Pull the electric parking brake switch up gently
and securely. u The indicator in the switch comes on.
u The parking brake and brake system
indicator (red) comes on.
■To release
The power mode must be in ON in order to
release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The indicator in the switch goes off.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing downhill on steep hills.
■Parking Brake1 Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead.
2 If the 12-Volt Battery Is Dead P. 671
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four wheels
are applied by the electric servo brake system until
the vehicle comes to a stop. The electric parking
brake then applies, and the switch should be
released.

Driving
Your vehicle is equipped with disc brakes at all four wh eels. 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.

■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 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.
Applying constant pressure to the brakes while going
down a long hill can cause the brakes to heat up,
resulting in a loss of stopping power.
Therefore, when descendi ng a long hill, release the
accelerator pedal and allow regenerative braking to
slow the vehicle down.
To adjust the rate of deceleration, use the
deceleration pa ddle selector.
When the high voltage battery has fully recharged,
regenerative braking may not be possible.

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.

Safety When Performing Maintenance
Some of the most important safety pr ecautions are given here. However, we
cannot warn you of every conceivable hazard that can arise in performing
maintenance. Only you can decide whether you should perform a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.

The condition of the battery is monitored by a
sensor located on the negative terminal of the
battery. If there is a problem with this sensor,
the driver information interface will display a
warning message. If this happens, have your
vehicle inspected by a dealer.
Check the battery termina ls for corrosion monthly.
If your vehicle's battery is disconnected or goes dead:
• The audio system is disabled.

uuCleaning uExterior Care
Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resi n-coated parts, they
may stain or the coating may peel. Prompt ly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.
