Precaution for Brake SystemINFOID:0000000005148094
CAUTION:
• Always use recommended brake fluid. Refer to MA-13, "
Fluids and Lubricants".
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosen e. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the ABS actuator and electric unit (con trol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
Refer to BR-30, "
Brake Burnishing Procedure" (front disc brake) or BR-35, "Brake Burnishing Proce-
dure" (rear disc brake).
WARNING:
• Clean brake pads and shoes with a waste cl oth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000005148095
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine
compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.
• When an error is indicated by ABS or another warning lamp, collect all necessary information from customer (what symptoms are present under what conditions) and check for simple causes before starting diagnosis.
Besides electrical system inspection, check boos ter operation, brake fluid level, and fluid leaks.
• If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts, stop-
ping distance or steering stability may deteriorate.
• If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness pinches, open circuits or improper wiring.
• If the following components are replaced with non-genuine components or modified, the VDC OFF indicator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorbers, struts, springs , bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, roto rs, calipers, etc.), components related to engine (muf-
fler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
• Driving with broken or excessively worn suspensi on components, tires or brake system components may
cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC system may not
operate properly.
• When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The noise is a result of the normal operation of the TCS and VDC.
• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as sharp curves on a freeway), the VDC may not operate no rmally, or the VDC warning lamp and the SLIP indi-
cator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the engine.

PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
• Intelligent Cruise Control is functionally limited. This never support careless driving and low visibility (rain,
fog, etc.). Drive the vehicle safely. Keep a safe distance between vehicles by decreasing the vehicle speed
according to the driving condition etc.
• Intelligent Cruise Control never stop the vehicle automatically. Intelligent Cruise Control is automatically released, and the buzzer sounds if any vehicle ahead is not detected when the vehicle speed is approxi-
mately 35 km (21.5 MPH) or less.
• Use this system when the vehicle speed does not ex tremely change. This system may not properly function
when any vehicle cuts in, or when the vehicle ahead suddenly applies the brake. Then, the warning (buzzer
and indication) activates.
• Never use Intelligent Cruise Control in the following conditions.
- A well-trafficed road, and a tight turn. It may cause any accident because the driving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road) The vehicle may lose the control by wheelspin.
- The vehicle drives in bad whether (rain, fog, snow etc.). The distance from the vehicle ahead is not detected pr ecisely if the whether condition is bad. Intelligent
Cruise Control is released automatically if the wiper activates in low or high speed.
- The vehicle receives bright light (sunshine etc.). The distance from the vehicle ahead is not detected pr ecisely if bright light enters in the vehicle.
- Raindrop or snow is on the sensor.
The distance from the vehicle ahead is not detected precisely if raindrop or snow attaches on the sensor.
- A steep downhill The setting vehicle speed may exceed if Intelligent Cr uise Control does not detect the vehicle ahead. The
brake may heat up in the vehicle-to-vehicle distance control mode.
- A repeated uphill and downhill Intelligent Cruise Control may not detect the vehicle ahead precisely. An accident may occur by tailgating.
- Maintaining proper vehicle distance is diff icult due to frequent acceleration/deceleration.
It may cause any accident because the driving does not fit to the road condition if keeping a proper vehicle-
to-vehicle distance is difficult.
- When entering in the highway interchange (swerving off the main line),
Unexpected accident may cause if the vehicle ahead drives slower
than the preset vehicle speed. The vehicle-to-vehicle distance con-
trol mode accelerates automatically because the vehicle ahead is
not detected on the lane if the own vehicle or the vehicle ahead
changes the lane.
• Intelligent Cruise Control does not activate to the parking vehicles, and vehicles driving extremely slower than the own vehicle. Never
hit the vehicle stopping at a tollgate, or the tail end of traffic jam.
• Intelligent Cruise Control does not activate to the vehicle edging way, and non-vehicle objects (passengers etc.).
• This function detects the reflector of the vehicle ahead. Intelligent Cruise Control may not detect the vehicle
ahead, and keep a proper vehicle-to-vehicle distance in the following conditions. Drive the vehicle according
to the driving condition.
- The vehicle ahead installs the reflector higher (trailer etc.).
- The rear of the vehicle ahead is extremely dirt.
- The vehicle ahead or vehicle on other lanes splashes water or snow on the road.
- The vehicle ahead provides dark exhaust gas. Smoke blocks the visibility.
- The vehicle ahead attaches film on the reflector. The vehicle ahead does not install the reflector. The reflec- tor is broken.
- Extremely heavy load is on the rear seat or in the cargo area.
- The vehicle drives on a repeated uphill and downhill
