maintenance NISSAN FRONTIER 2023 User Guide

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.
To turn off the High Beam Assist system,
turn the headlight switch to the
posi-
tion or select the low beam position by
placing the lever in the neutral position.
Ambient image sensor maintenance
The ambient image sensorO1for the High
Beam Assist system is located in front of
the inside mirror. To maintain the proper
operation of the high beam assist system
and prevent a system malfunction, be sure
to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the ambient image sensor.
• Do not strike or damage the areas around the ambient image sensor. Do
not touch the sensor lens that is located
on the ambient image sensor. If the ambient image sensor is damaged
due to an accident, it is recommended that
you visit a NISSAN dealer.
Battery saver system
The battery saver system automatically
turns off the following lights af ter a period
of time when the ignition switch is placed in
the OFF position and the doors are closed:
• Headlights, when the headlight switch is
in the
orposition
• Interior lights, when lef t in the ON position (if so equipped)
Af ter the headlights automatically turn off
with the headlight switch in the
orposition, the headlights will illuminate
again if the headlight switch is moved to
the OFF position and then turned to the
orposition.
CAUTION
Even though the battery saver feature
automatically turns off the headlights
af ter a period of time, you should turn
the headlight switch to the OFF posi-
tion when the engine is not running to
avoid discharging the vehicle battery.

Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.Additional information:
• When using a wheel without the TPMS
such as a spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure of your tires are adjusted. Af ter
the tires are inflated to the recom-
mended pressure, the vehicle must be
driven at speeds above 16 mph (25 km/h)
to activate the TPMS and turn off the
low tire pressure warning light. Use a tire
pressure gauge to check the tire
pressure.
• The “Tire Pressure Low — Add Air” warning appears in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure is
detected. The “Tire Pressure Low — Add
Air” warning turns off when the low tire
pressure warning light turns off. • The “Tire Pressure Low — Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
• The “Tire Pressure Low — Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
• The Tire and Loading information label is located in the driver's door opening.
For additional information, see “Low tire
pressure warning light” (P. 2-17) and “Tire
Pressure Monitoring System (TPMS)” (P. 6-3).
5-6Starting and driving

•Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, see “Wet
brakes” (P. 5-118).
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, see “Maintenance
under severe operating conditions”
(P. 9-7).
WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If
the engine stops while the vehicle is
being driven, this could lead to a crash
and serious injury. When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch position will illuminate as follows:
Push center:
• Once to change to ACC.
• Two times to change to ON.
• Three times to return to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.
When the ignition switch cannot be placed
in the OFF position, proceed as follows:
1. Move the shif t lever to the P (Park)
position.
2. Push the ignition switch. The ignition switch position will change to the ON
position.
3. Push the ignition switch again to the OFF position.
The shif t lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the ignition switch cannot be moved
from the LOCK position.
