2019 NISSAN FRONTIER PRO-4X differential

The E-Lock system can help provide added
traction if the vehicle is stuck or becoming
stuck.
To activate the E-Lock system:∙ The 4WD switch must be in the 4LO po- sition (4-Wheel Drive vehicles),
∙ The vehicle must be stopped or moving at 4 mph (7 km/h) or less, and
∙ The E-Lock system switch must be turned on. When the E-Lock switch is turned on, the
indicator light will flash until the system
engages. However, if all operation condi-
tions listed above are not met or the sys-
tem becomes disengaged, the indicator
light will continue to flash.
The Anti-lock Braking System (ABS) is dis-
abled and the ABS light illuminates when
the E-Lock system is on. Also, the Vehicle
Dynamic Control (VDC) system is disabled
and the VDC light illuminates when the
E-Lock system is on.
For additional information, refer to “Elec-
tronic locking rear differential (E-Lock) sys-
tem” in the “Starting and driving” section of
this manual for further explanation and
system limitations.

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, refer to
“Electronic locking rear differential (E-Lock)
system switch” in the “Instruments and
controls” section of this manual. Once the
system fully engages, the indicator light in
the instrument panel will remain on. When
the system is activated, both rear wheels
will engage, 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 (ABS) system is dis-
abled and the ABS light illuminates when
the E-Lock system is on. Also, the Vehicle

∙ Do not start or run the engine whilevehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
∙ Do not allow passengers to stay in the vehicle while it is on the jack.
∙ Never run the engine with a wheel(s) off the ground. It may cause the ve-
hicle to move.
Always refer to the illustration for the cor-
rect placement and jack-up points for your
specific vehicle model and jack type.
Carefully read the caution label attached
to the jack body and the following in-
structions. 1. Loosen each wheel nut 1 or 2 turns by
turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.
