ABS NISSAN FRONTIER 2021 User Guide

Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds above3-6mph(5-10
km/h). The speed varies according to road
conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving. • The ABLS system uses automatic brak-
ing to transfer power from a slipping drive
wheel to the wheel on the same axle with
more traction. The ABLS system applies
braking to the slipping wheel, which helps
redirect power to the other wheel.
• On 4–Wheel Drive models the ABLS sys- tem operates in both 4H and 4LO modes.
If 4WD mode is engaged, the ABLS sys-
tem operates for both drive axles. On
2–Wheel Drive vehicles, the ABLS system
operates on the drive axle only.
• The ABLS system is always on. In some conditions, the system may automati-
cally turn the ABLS system off. If the sys-
tem is automatically turned off, normal
brake function will continue. ABLS will
function even when the Vehicle Dynamic
Control system is turned off.
• The ABLS does not operate if both wheels on a drive axle are slipping.

WARNING
• The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driv-
ing and cornering on slippery sur-
faces and always drive carefully.
• Do not modif y the vehicle's suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deterio-
rated, the VDC system may not oper-
ate properly. This could adversely af-
fect vehicle handling performance,
and the
indicator light may flash
or theindicator light may
illuminate.
• If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC sys-
tem may not operate properly and
both the
andindicator
lights may illuminate. •
If engine control related parts are not
NISSAN recommended or are ex-
tremely deteriorated, both the
andindicator lights may
illuminate.
• When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
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 light may
flash or theindicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
• If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate.
• The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.

5-36Starting and driving

4. If the fuse is openOA, replace it with an
equivalent good fuse
OB.
5. Reverse step 2 to reinstall fuse box cover.
6. If a new fuse also opens, have the elec- trical system checked and repaired. It is
recommended that you visit a NISSAN
dealer for this service.
NOTE:
Your vehicle may not be equipped with
all fuses listed on the fuse label.
Extended storage switch
If any electrical equipment does not oper-
ate, remove the extended storage switch
and check for an open fuse.
NOTE:
The extended storage switch is used for
long term vehicle storage. Even if the ex-
tended storage switch is broken it is not
necessary to replace it. Replace only the
open fuse in the switch with a new fuse. How to replace the extended storage
switch:
1. To remove the extended storage switch,
be sure the ignition switch is in the OFF
or LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
OAfound on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box
