When the vehicle is stuck,
cSet the 4WD shift switch to 4H or 4LO.
cUse the Electronic Locking Rear Differential
(E-Lock) system (if so equipped) . Turn the
switch ON while the vehicle is stationary and
apply the throttle to try to free the vehicle.
cIf it is difficult to free the vehicle, rock the
vehicle back and forth between reverse and
drive gears.
cIf the vehicle is stuck deep in mud, place
stones or wooden blocks under the tires.
Then try the recovery procedures above. Tire
chains may be effective.
CAUTION
cDo not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
cAvoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
4WD shift switch operations
cShift the 4WD shift switch to either the
2WD, 4H or 4LO position, depending on
driving conditions.
cIf the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the key switch is
turned off while in the 4H or 4LO posi-
tion, you may feel a jolt. This is not
abnormal.cWhen the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the selector lever is shifted to N or
P. This occurs because the transfer
clutch is released and not because of a
malfunction.
CAUTION
cWhen driving straight, shift the 4WD
shift switch to the 2WD or 4H position.
Do not move the 4WD shift switch when
making a turn or reversing.
cDo not shift the 4WD shift switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears (D1 or D2) or
manual transmission (1st gear or 2nd
gear) for engine braking.
cDo not operate the 4WD shift switch
with the rear wheels spinning.
cBefore placing the 4WD shift switch in
the 4H position from 2WD, ensure the
vehicle speed is less than 62.5 MPH
(100 km/h) . Failure to do so can dam-
age the 4WD system.
cNever shift the 4WD shift switch be-
tween 4LO and 4H while driving.

cWhen the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in 4H. Be especially
careful when driving. If corresponding
parts are malfunctioning, the 4WD
mode will not be engaged even if the
4WD shift switch is shifted.
cDo not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift
switch to 2WD.
– in the 4LO position for automatic
transmission vehicles, stop the ve-
hicle and shift the transmission se-
lector to the N position with the
brake pedal depressed and shift the
4WD shift switch to 2WD.– in the 4LO position for manual trans-
mission vehicles, stop the vehicle
and shift the transmission shift lever
to the N position with the clutch
pedal depressed and shift the 4WD
shift switch to 2WD.
cIf the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.The E-Lock system can provide additional trac-
tion and should only be used when a vehicle has
become or is becoming stuck. This system oper-
ates by electronically “locking” the two rear drive
wheels together, 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 vehicles) .
When added traction is required, activate the
E-Lock system by pushing the switch ON. See
“Electronic Locking Rear Differential (E-Lock)
system switch” in the “Instruments and Controls”
section. Once the system fully engages, the indi-
cator 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 system will only
function 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 Brake (ABS) system is disabled
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 further brake and clutch fluid specification
information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
consumer information” section of this manual.
WARNING
Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated fluid
may damage the brake and clutch sys-
tems. The use of improper fluids can dam-
age the brake system and affect the vehi-
cle’s stopping ability.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid is
spilled, immediately wash the surface
with water.BRAKE FLUID
Check the brake fluid level in the reservoir. If the
fluid level is below the MIN line or the brake
warning light comes on, add Genuine NISSAN
Super Heavy Duty Brake Fluid or equivalentDOT
3fluid up to the MAX line. If fluid must be added
frequently, the system should be checked by a
NISSAN dealer.
CLUTCH FLUID
Check the clutch fluid level in the reservoir
(manual transmissions only) . If the fluid level is
below the MIN line, add Genuine NISSAN Super
Heavy Duty Brake Fluid or equivalentDOT 3fluid
up to the MAX line. If fluid must be added fre-
quently, the system should be checked by a
NISSAN dealer.
For further brake and clutch fluid specification
information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
