Starting and Operating Instructions
NOTICE
Continuing to drive with
worn-out brake pads could
result in costly brake repairs.
Improperly tightened wheel nuts
can lead to brake pulsation. When
tires are rotated, inspect brake
pads for wear.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
See "Specifications and Capacities"
in Section 4 for the proper wheel
nut torque.

Brake Adjustment

Every time you apply the brakes to
stop, your disc brakes adjust them-
selves for wear.

Brake Pedal Travel

See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that service is required.

Antilock Brake System

The antilock brake system helps
you maintain directional stability
on wet or slippery road surfaces. It
automatically controls the brake
operation when braking.
As you brake, the system receives
updates on wheel speed and
controls braking pressure at each
wheel separately to make the most
of available tire and road condi-
tions.
This occurs only during a brake
application which would have
caused one or more wheels to
lock. You don't have to 'pump' the
brakes. Just hold the brake pedal
down. You may feel or hear it
pulsate, but this is normal.
See "Antilock Brake System Warn-
ing Light" in Section 1 for more
information.
