Starting and driving -> Differential lock mode switch for Your Nissan Patrol SUV Sixth Generation (2010-2023)

DIFFERENTIAL LOCK MODE  
SWITCH (except for Mexico)  
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM  
WARNING:  
.
.
In 4WD AUTO and 4H mode, the rear  
differential lock-up device does not oper-  
ate when the differential lock mode  
switch is turned to the “ON” position.  
(The DIFF-LOCK indicator light will flash.)  
.
The Vehicle Dynamic Control (VDC) sys-  
tem is designed to help the driver main-  
tain stability but does not prevent  
accidents due to abrupt steering opera-  
tion at high speeds or by careless or  
dangerous driving techniques. Reduce  
vehicle speed and be especially careful  
when driving and cornering on slippery  
surfaces and always drive carefully.  
WARNING:  
Use the rear differential lock (DIFF-LOCK)  
only in an emergency when it is not  
possible to free  
a stuck vehicle even  
using the 4L position.

.
Do not modify the vehicle’s suspension. If  
suspension parts such as shock absor-  
bers, struts, springs, stabilizer bars, bush-  
ings and wheels are not NISSAN  
recommended for your vehicle or are  
extremely deteriorated, the VDC system  
may not operate properly. This could  
adversely affect vehicle handling perfor-  
mance, and the VDC warning light  
may illuminate.  
.
.
When the DIFF-LOCK is in operation, turn-  
ing the vehicle becomes hard and, espe-  
cially at high speeds, is dangerous.  
While DIFF-LOCK is on, the Anti-lock  
Braking System (ABS) warning light illu-  
minates. This indicates that anti-lock  
function may not fully operate.  
Do not operate the DIFF-LOCK when the  
vehicle is turning or when one side wheel  
is rotating. Otherwise the power train  
system parts could be damaged.  
Avoid quick starts while the DIFF-LOCK is  
in operation. Otherwise the power train  
system parts could be damaged.  
The rear differential lock (DIFF-LOCK) is de-  
signed to transmit engine power to the left and  
right wheels equally.  
If your vehicle is stuck in sand, snow, mud, etc.  
or one wheel is off the ground and the  
differential lock is not on, engine power is  
transmitted to one wheel causing it to spin,  
so leaving insufficient traction on the other  
wheel. The rear differential lock allows the left  
and right wheels to rotate as a unit, enabling  
your vehicle to free itself.

If brake related parts such as brake pads,  
rotors and calipers are not NISSAN re-  
commended or are extremely deterio-  
rated, the VDC system may not operate  
properly and the VDC warning light  
may illuminate.  
To lock the rear differential gear, reduce the  
vehicle speed below 7 km/h (4 MPH) and turn  
the 4WD shift switch to the 4L position. Then  
push the differential lock mode switch to the  
“ON” position. The differential lock (DIFF-LOCK)

When driving on extremely inclined sur-

LOCK), or during normal driving, push the  
differential lock mode switch to the “OFF”  
position. The DIFF-LOCK indicator light will turn  
off after the differential lock is released.

You may feel a pulsation in the brake pedal  
and hear a noise or vibration from under  
the hood. This is normal and indicates that

When the vehicle is stuck in mud or snow, the  
VDC system reduces the engine output to  
reduce wheel spin. The engine speed will be  
reduced even if the accelerator is depressed to  
the floor. If maximum engine power is needed  
to free a stuck vehicle, turn the VDC system off.

The computer has a built-in diagnostic feature  
that tests the system each time you start the  
engine and move the vehicle forward or in  
reverse at a slow speed. When the self-test  
occurs, you may hear a “clunk” noise and/or  
feel a pulsation in the brake pedal. This is

the steered path despite increased  
steering input)  
Push the VDC OFF switch again or restart the  
engine to turn ON the system.

certain road or driving conditions).  
The VDC system can help the driver to maintain  
control of the vehicle, but it cannot prevent loss  
of vehicle control in all driving situations.
