Toyota RAV4 1999 Operating Manual page 139

You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti- lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the "ABS" brake
pedal: When the anti- lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti- lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. Pump-
ing the brake pedal makes the stopping
distance longer.
The brake pedal pulsation caused by the
anti- lock brake system may indicate haz-
ardous road surface conditions. Although
the anti- lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti- lock brake system cannot overcome
the laws of physics that act on your ve-
hicle:
"
Braking capability is dependent on tire
friction with the road surface.
"
Even though the anti- lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering
speeds, or in violent maneuvers.
"
Avoid high speeds on wet roads. The
anti- lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti- lock brake
system, your vehicle may require a longer
stopping distance in the following cases:
"
Driving on rough, gravel or snow- cov-
ered roads.
"
Driving with tire chains installed.
"
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than
manufacturer's designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock brake system from operating at
full effectiveness.
