2021 NISSAN TITAN service indicator

4WD shif t indicator
The 4WD shif t indicator is located in the
vehicle information display.
While the engine is running, the 4WD shif t
indicator will illuminate the position se-
lected by the 4WD shif t switch.
•The 4WD shif t indicator may come on
while shif ting from one drive mode to
the other. When the shif ting is com-
pleted, the 4WD shif t indicator will stay
on.
• If the 4WD vehicle information display warning message comes on, the 4WD in-
dicator goes out.
CAUTION
• If the 4WD shif t indicator indication
changes to 2WD when the 4WD shif t
switch is shif ted to the 4H position at
low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the
indicator does not return to normal
and the 4WD vehicle information dis-
play warning message comes on,
have the system checked. It is recom-
mended that you visit a NISSAN
dealer for this service.

5-110Starting and driving

–In the 4LO position, stop the ve-
hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
• If the warning message is still on af-
ter the above operation, have your
vehicle checked as soon as possible.
It is recommended that you visit a
NISSAN dealer for this service.
• The transfer case may be damaged if
you continue driving with the warn-
ing message on. The E-Lock system can provide additional
traction and should only be used when a
vehicle has become or is becoming stuck.
This system operates by electronically
“locking” the two rear drive wheels to-
gether, allowing them to turn at the same
speed. The system is used when it is not
possible to free a stuck vehicle even when
using the 4LO position (4-Wheel Drive ve-
hicles).
When added traction is required, activate
the E-Lock system by pushing the switch
on. For additional information, see “Elec-
tronic locking rear differential (E-Lock) sys-
tem switch” (P. 2-59). Once the system fully
engages, the indicator light in the instru-
ment panel will remain on. When the sys-
tem is activated, both rear wheels will en-
gage, providing added traction.
The rear wheels may momentarily slip or
move to engage the system, and the sys-
tem will only engage up to approximately 4
mph (7 km/h). Once the vehicle is free, the
system should be turned off and driving
resumed.
The Anti-lock Braking System (ABS) is dis-
abled and the ABS warning light illumi-
nates when the E-Lock system is on.WARNING
• Never leave the E-Lock system on
when driving on paved or hard-
surfaced roads. Turning the vehicle
may result in the rear wheels slipping
and result in an accident and per-
sonal injury. Af ter using the E-Lock
system to free the vehicle, turn the
system off.
• Use the E-Lock system only in an
emergency when it is not possible to
free a stuck vehicle even when using
4LO. Never use the E-Lock system on
a slippery road surface such as snow
or ice surface. Using the E-Lock sys-
tem when driving in these road con-
ditions may cause unexpected
movement of the vehicle during en-
gine braking, accelerating or turning,
which may result in an accident and
serious personal injury.
• Observe the above warnings. Other-
wise, loss of normal steering control
may result. This may result in an ac-
cident and serious personal injury.

5-112Starting and driving

Be careful not to let anything get into the
washer nozzle
OD. This may cause clogging
or improper windshield–washer operation.
If something gets into the nozzle, remove it
with a needle or small pin
OC. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard. Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information on
the appropriate maintenance schedule re-
garding brake inspections, see "Mainte-
nance schedules" (P. 9-7).LDI2710

spected for wear, cracking,
bulging or objects caught in
the tread. If excessive wear,
cracks, bulging or deep cuts
are found, the tire(s) should be
replaced.
