How to handle the sensor

The sensor for the Preview Function is common with Intelligent Cruise Control and is located below the front bumper.

To keep the Preview Function operating properly, be sure to observe the following:

.Always keep the sensor clean. Wipe with a soft cloth carefully so as not to damage the sensor.

.Do not strike or damage the areas around the sensor. Do not touch or remove the screw located on the sensor. Doing so could cause failure or malfunction. If the sensor is da- maged due to an accident, contact an INFINITI dealer.

.Do not attach a sticker (including transparent material) or install an accessory near the sensor. This could cause failure or malfunction.

ANTI-LOCK BRAKING SYSTEM (ABS)

WARNING

.The Anti-lock Braking System (ABS) is a sophisticated device, but it cannot pre-

vent accidents resulting from careless or dangerous driving techniques. It can help maintain vehicle control during braking on slippery surfaces. Remember that stopping distances on slippery surfaces will be longer than on normal surfaces even with ABS. Stopping dis- tances may also be longer on rough, gravel or snow covered roads, or if you are using tire chains. Always maintain a safe distance from the vehicle in front of you. Ultimately, the driver is responsible for safety.

.Tire type and condition may also affect braking effectiveness.

—When replacing tires, install the specified size of tires on all four wheels.

—When installing a spare tire, make sure that it is the proper size and type as specified on the Tire and Loading Information label. See “TIRE AND LOADING INFORMATION LABEL” in the “9. Technical and consumer information” section of this manual.

—For detailed information, see “WHEELS AND TIRES” in the “8. Maintenance and do-it-yourself”sec- tion of this manual.

The Anti-lock Braking System (ABS) con- trols the brakes so the wheels do not lock during hard braking or when braking on slippery surfaces. The system detects the rotation speed at each wheel and varies the brake fluid pressure to prevent each wheel from locking and sliding. By pre- venting each wheel from locking, the system helps the driver maintain steering control and helps to minimize swerving and spinning on slippery surfaces.

Using the system

Depress the brake pedal and hold it down. Depress the brake pedal with firm steady pressure, but do not pump the brakes. The ABS will operate to prevent the wheels from locking up. Steer the vehicle to avoid obstacles.

WARNING

Do not pump the brake pedal. Doing so may result in increased stopping distances.

Self-test feature

The ABS includes electronic sensors, elec- tric 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
