2019 NISSAN FRONTIER PRO-4X service

∙ It is recommended that you visit aNISSAN dealer for work on and around
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical
test equipment and probing devices
should not be used on the preten-
sioner system.
∙ If you need to dispose of the preten- sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with the
seat belt retractor, the pretensioner(s) help
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt an-
chor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts. When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.

Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags and pretensioner(s) are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag warning light remains illu-
minated af ter inflation has occurred. These
systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.

If the ABS warning light illuminates while
the engine is running or while driving, it
may indicate the ABS is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system
then operates normally but without anti-
lock assistance. For additional information,
refer to “Brake system” in the “Starting and
driving” section of this manual.

2. If the brake fluid level is correct, havethe warning system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.

∙If the light does not illuminate with the
ignition switch placed in the ON posi-
tion, have the vehicle checked as soon
as possible. It is recommended that you
visit a NISSAN dealer for this service.
∙If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury or death.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure show on
the Tire and Loading Information label
located in the driver’s door opening to
turn the low tire pressure warning light
off. If the light still illuminates while
driving af ter adjusting the tire pres-
sure, a tire may be flat or the TPMS may
be malfunctioning. If you have a flat
tire, replace it with a spare tire as soon
as possible. If no tire is flat and all tires
are properly inflated, have the vehicle
checked. It is recommended that you
visit a NISSAN dealer for this service.
∙ When replacing a wheel without theTPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.

OPERATING TIPS
The sunload sensor1, located on the top
center of the instrument panel, helps the
system maintain a constant temperature.
Do not put anything on or around this sen-
sor.
∙ When the engine coolant temperature and outside air temperature are low, the
air flow from the foot outlets may not
operate for a maximum of 150 seconds.
However, this is not a malfunction. Af ter
the coolant temperature warms up, air
flow from the foot outlets will operate
normally. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.

3. While pulling up on the parking brakelever slightly, press the button
Band
lower the lever completely.
4. Before driving, be sure the brake warn- ing light goes out.
PRECAUTIONS ON CRUISE
CONTROL
1. ACCEL•RES switch
2. COAST•SET switch
3. CANCEL switch
4. ON•OFF switch
∙ If the cruise control system malfunc- tions, it cancels automatically. The SET
indicator light in the instrument panel
then blinks to warn the driver. ∙ If the SET indicator light blinks, turn the
ON•OFF switch off and have the system
checked. It is recommended that you
visit a NISSAN dealer for this service.
∙ The SET indicator light may blink when the ON•OFF switch is turned on while
pushing the ACCEL•RES, COAST•SET, or
CANCEL switch (located on the steering
wheel). To properly set the cruise con-
trol system, use the following proce-
dures.

WARNING
∙ While driving on a slippery surface, becareful when braking, accelerating or
downshif ting. Abrupt braking or ac-
celerating 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 as-
sist for the brakes will not work. Brak-
ing 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 lon-
ger 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 stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
