Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h).
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure.
This action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
When accelerating on slippery surfaces the tire
may spin or slip. With the vehicle traction control
system (TCS), sensors detect these movements
and control the braking and engine output to help
improve vehicle stability while accelerating.
● When the traction control system is operat-
ing, the slip indicator in the instrument panel
blinks.
● If the slip indicator blinks, the vehicle is un-
der slippery conditions. Be sure to drive
carefully. See “Slip indicator light”and “Trac-
tion control system (TCS) off indicator light”
in the “Instruments and controls” section of
this manual.
● If a malfunction occurs in the system,
the
and indicator lights
come on in the instrument panel.
As long as these lights are on, the traction control
function is canceled. The vehicle will behave like
a vehicle without the system.
WARNING
● The traction control system is designed
to help improve driving stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
● If brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the traction control system
may not operate properly and the
indicator light may come on.
● Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs and bushings
are not standard equipment or are ex-
tremely deteriorated, the traction con-
trol system may not operate properly
and the
indicator light may come
on.
