brake rotor NISSAN FRONTIER 2014 D23 / 3.G Owners Manual

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance.
POWER STEERING BRAKE SYSTEM
5-34Starting and driving

When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
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 operating. 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 re-
quired while driving.●
ABLS system uses automatic braking to
transfer power from a slipping drive wheel to
the wheel on the same axle with more trac-
tion. The ABLS system applies braking to
the slipping wheel, which helps redirect
power to the other wheel.
● On 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system operates for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
● The ABLS system is always ON. In some
conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake func-
tion will continue. ABLS will function even
when the VDC system is turned OFF.
● The ABLS does not operate if both wheels
on a drive axle are slipping.WARNING
● The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering opera-
tion or by careless driving or dangerous
driving practices. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces. Al-
ways drive carefully.
●
Do not modify the vehicle’s suspension. If
suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not NISSAN ap-
proved for your vehicle or are extremely
deteriorated, the ABLS system may not
operate properly. This could adversely af-
fect vehicle handling performance, and
the slip indicator light may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the ABLS system may not
operate properly and the slip indicator
light may illuminate.
● If wheels or tires other than the NISSAN
recommended ones are used, the ABLS
system may not operate properly and
the slip indicator light may illuminate.

●Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or the
indicator light may
illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and the
indica-
tor light may illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, the
indicator light
may illuminate.
● When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
the
indicator light may illuminate.
Do not drive on these types of roads. ●
When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator may flash or
the
indicator light may illuminate.
This is not a malfunction. Restart the
engine after driving onto a stable
surface.
● If wheels or tires other than the NISSAN
recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or
the
indicator light may illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
WARNING
● Never rely solely on the hill descent
control system to control vehicle speed
when driving on steep downhill grades.
Always drive carefully and attentively
when using the hill descent control sys-
tem and decelerate the vehicle speed by
depressing the brake pedal if neces-
sary. Be especially careful when driving
on frozen, muddy or extremely steep
downhill roads. Failure to control ve-
hicle speed may result in a loss of con-
trol of the vehicle and possible serious
injury or death.
●
The hill descent control may not control
the vehicle speed on a hill under all load
or road conditions. Always be prepared
to depress the brake pedal to control
vehicle speed. Failure to do so may result
in a collision or serious personal injury.
The hill descent control system helps maintain
vehicle speed when driving under 15-21 MPH
(25-35 km/h) on steeper downhill grades. Hill
descent control is useful when engine braking
alone in 4H or 4L cannot control vehicle speed.
Hill descent control applies the vehicle brakes to
control vehicle speed allowing the driver to con-
centrate on steering while reducing the burden of
brake and accelerator operation.
