2011 NISSAN XTERRA ABS

This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
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. Remem-
ber 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 respon-
sible 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
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls 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 pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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, 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.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) . The speed varies according to road
conditions.
Starting and driving5-33

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 ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
approved for your vehicle or are ex-
tremely deteriorated, the ABLS system
may not operate properly. This could
adversely affect vehicle handling per-
formance, 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.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
5-34Starting and driving

A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs. Check with the
trailer and towing equipment manufacturers to
determine if they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the
surge brake, hitch or trailer manufacturer
to determine if and how this can be done.
Follow the instructions provided by the manufac-
turer for installing and using the weight-
distributing hitch system.
General set-up instructions are as follows:1. Park unloaded vehicle on a level surface. With the ignition on and the doors closed,
allow the vehicle to stand for several minutes
so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the center of
the vehicle. 3. Attach the trailer to the vehicle and adjust
the hitch equalizers so that the front bumper
height is within0-.5inches (0 – 13 mm) of
the reference height measured in step 2. The
rear bumper should be no higher than the
reference height measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If the
rear bumper is higher than the measured
reference height when loaded, the vehicle
may handle unpredictably which could
cause a loss of vehicle control and cause
serious personal injury or property
damage.
Sway control device
Sudden maneuvers, wind gusts, and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to make
sure the sway control device will work with the
vehicle, hitch, trailer and the trailer’s brake sys-
tem. Follow the instructions provided by the
manufacturer for installing and using the sway
control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb (909 kg) .
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 3,500 lb (1,510 kg) .
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 5,000 lb (2,272 kg) .
CAUTION
●Special hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches, ball mounts and
hitch balls for pickup trucks and sport
utility vehicles are available at a
NISSAN dealer.
● The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
● Do not use axle-mounted hitches.
