BRAKE SYSTEM

If power assist is lost for any reason (for example,

repeated brake applications with the engine off), the

brakes will still function. However, you will experience a

substantial increase in braking effort to stop the vehicle.

If either the front or rear hydraulic system loses normal

braking capability, the remaining system will still func-

tion with some loss of overall braking effectiveness. This

will be evident by increased pedal travel during applica-

tion, greater pedal force required to slow or stop, and

activation of the “Brake Warning Light” and the “ABS

Warning Light” (if equipped) during brake use.

The brake system power assist is provided by a hydro-

boost unit which shares fluid with the power steering

system. You may experience some clicking or hissing

noises from the hydro-boost system during hard braking

conditions.

NOTE: Under cold temperatures, pedal effort will be

higher than normal until the power steering fluid reaches

operating temperature.
