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.

● ABLS is a form of traction control using

sensors from the Anti-lock Brake System

(ABS) to transfer power from a slipping drive

wheel to a wheel with more traction. The

ABLS system applies braking to the slipping

wheel, which helps redirect power to an-

other wheel.

● On 4WD models the ABLS system operates

in both 4H and 4LO modes. If 4WD mode is

engaged, the ABLS system will operate for

both drive axles. On 2WD vehicles, the

ABLS system operates on the drive axle

only.

● The ABLS system is always ON unless the

system detects brake pad overheating. If

high brake pad temperature is detected, it

will turn OFF, but normal brake function will

continue. ABLS will function even when the

VDC system (if so equipped) is turned OFF.

WARNING

The ABLS system provides increased trac-

tion, but will not prevent accidents due to

abrupt steering operation or by careless

driving or dangerous driving practices.

Reduce vehicle speed and be especially

careful when driving and cornering on

slippery surfaces, and always drive

carefully.

The Vehicle Dynamic Control (VDC) system uses

various sensors to monitor driver inputs and ve-

hicle motion. Under certain driving situations, the

system will control braking and engine output to

help keep the vehicle on its steered path.

● When the Vehicle Dynamic Control (VDC)

system is operating, the SLIP indicator in

the instrument panel blinks.

● If the 4WD transfer case is shifted into 4LO

the

indicator light will come on and

the VDC system will be turned off. See

“Transfer case shifting procedures” earlier in

this section.

● If the SLIP indicator blinks, the road condi-

tions may be slippery. Be sure to adjust your

speed and driving to these conditions. See

“Slip indicator light”, and “Vehicle Dynamic

Control (VDC) off indicator light” in the “In-

struments and controls” section.

If the battery is removed or discharged, the Trac-

tion Control System may be disabled and the
SLIP and

indicator lights will not turn off

after 2 seconds when the ignition switch is turned

to the ON position.
Perform the following procedure to reset the

system:

● Start the engine and set the steering wheel

in the straight forward position.
