cIf it is difficult to free the vehicle, repeat
forward and backward movement to in-
crease the movement.
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, AUTO, 4H or 4LO position, depend-
ing on driving conditions.
cWith the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD)!50 : 50 (4WD)]. This results
in improved driving stability.
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 AUTO, 4H or4LO, 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, AUTO 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) for en-
gine 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 or AUTO,
ensure the vehicle speed is less than
62.5 MPH (100 km/h). Failure to do so
can damage the 4WD system.
cNever shift the 4WD shift switch be-
tween 4LO and 4H while driving.

cEngine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery sur-
faces with the 4WD shift switch set in
AUTO.
4WD shift indicator light
The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.
cThe 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on. If the indicator light does
not come on immediately, make sure
the area around the vehicle is safe, anddrive the vehicle straight, accelerate or
decelerate or move the vehicle in re-
verse, then shift the 4WD shift switch.
cIf the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
cWhen the 4WD shift switch is turned to
the AUTO position at low ambient tem-
peratures, the 4WD shift indicator light
may show 4H. If this happens, all four
wheels are driven as torque distribution
is in the 4H position. Be careful as the
vehicle may become difficult to turn.
When the vehicle is driven, the 4WD
shift indicator light should change to
AUTO.
cIf the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or 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 warning light comes on,
have the system checked by the nearest
NISSAN dealer.

5. Remove the wheel nuts and then remove the
tire.
Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of this
manual.
1. Clean any mud or dirt from the surface be-
tween the wheel and hub.
2. Carefully put the spare tire on and tighten
the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly as illustrated until
they are tight.4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated. Lower the ve-
hicle completely.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
cRetighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
98 ft-lb (133 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication interval.

Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed the maximum speed rating of the tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
For additional traction on icy roads, studded tires
may be used. However, some U.S. states and
Canadian provinces prohibit their use. Check
local, state and provincial laws before installing
studded tires. Skid and traction capabilities of
studded snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P275/60R20 size tires. Installation of
the tire chains/cables on P275/60R20 size
tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P265/70R18 size tires on
your vehicle.
Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on yourvehicle and are installed according to the chain
manufacturer’s suggestions.Use only SAE
class “S” chains.Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de-
signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate the
use of a winter traction device (tire chains or
cables) . The minimum clearances are determined
using the factory equipped tire size. Other types
may damage your vehicle. Use chain tensioners
when recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of the
tire chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully load-
ing your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise, your
vehicle may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See “Flat tire” in the “In case of emer-
gency” section in this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced.cThe original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
cTires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact a NISSAN
dealer.
