Power steering
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is nor-
mal. It does not indicate power steering
system trouble.
Braking
„ Braking tips
T When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a re-
sult, brake stopping distance will be long-
er. To dry the brakes, drive the vehicle at
a safe speed while lightly depressing the
brake pedal to heat up the brakes.
T Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking.
T Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause
a loss of control of the vehicle. Keep driv-
ing straight ahead while gradually reduc-
ing speed. Then slowly pull off the road to
a safe place.
„ Brake system
T Two separate circuits
Your vehicle has a dual circuit brake sys-
tem. Each circuit works diagonally across
the vehicle. If one circuit of the brake sys-
tem should fail, the other half of the sys-
tem still works. If one circuit fails, the
brake pedal will go down much closer to
the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
T Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. If engine
manifold vacuum becomes insufficient,
such as when driving in a high-altitude
place, a vacuum pump assures a suffi-
cient vacuum to operate the brake boost-
er. Do not turn off the engine while driving
because that will turn off the brake boost-
er, resulting in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
Do not hold the steering wheel at the
fully locked position left or right for
more than five seconds. This may
damage the power steering pump.
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
