Traction control system (tcs) (if so equipped) -20 – NISSAN 2009 Quest User Manual
Page 276
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
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 road traction.
● When the TCS is operating, the
indicator in the instrument panel blinks.
● If the
indicator blinks, the vehicle
may be under slippery conditions. Be sure to
drive carefully. See “Slip indicator light” and
“Traction Control System (TCS) off indicator
light” in the “Instruments and controls” sec-
tion 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 de-
signed to help maintain traction with
the road surface but does not prevent
accidents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces 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, bushings and
wheels are not standard equipment or
are extremely deteriorated, the Traction
Control System may not operate prop-
erly and the
indicator light may
come on.
