ANTI−LOCK BRAKE SYSTEM
The ant i−lock brake system i s designed
to help pr event lock−up of the wheels
during a sudden braking or braking on
slipper y road surfaces. This assists i n
providing directional stability and steer-
ing per formance of the vehi cle under
these circumst ances.
Effect ive way to press the ABS brake
pedal: When the ant i−lock brake system
funct ion i s in act ion, you may feel the
brake pedal puls ating and hear a noise.
In this s ituat ion, t o let the anti −lock
brake system work for you, just hold the
brake pedal down mor e firml y. Do not
pump t he brake in a panic st op. Thi s

mance.
The anti−lock brake system becomes op-
erati ve after the vehicle has accel erated
to a speed i n exces s of appr oxim ately 10
km/h (6 mph). It st ops operating when the
vehic le deceler ates to a s peed below
approxi mately 5 km/ h (3 mph).
Depress ing the brak e pedal on s lipper y
road surf aces suc h as on a manhole cov-
er, a st eel pl ate at a cons truc tion sit e,
joint s i n a bri dge, et c. on a rai ny day

tem.
You m ay hear a c lic k or motor sound in
the engi ne c ompartment for a few seconds
when the engine is st arted or jus t after
