NISSAN recommends that towing dollies
be used when towing your vehicle or the
vehicle be placed on a flat bed truck as
illustrated.CAUTION
Never tow 4WD models with any of
the wheels on the ground as this
may cause serious and expensive
damage to the powertrain.

6-20In case of emergency
This section describes the procedure for
manually shifting the vehicle into the 4WD
mode (4L position) in case of an emer-
gency.
WHEN 4WD WARNING LIGHT ILLU-
MINATES
If the 4WD warning light illuminates while
driving, there may be a malfunction in the
4WD system. Stop the vehicle and have
the vehicle checked as soon as possible. It
is recommended you contact a NISSAN
dealer for this service. (See “NISSAN all-
mode 4WD®” (P.5-124).)
When the vehicle is stuck on an uneven
road (desert, mud, etc.) and the 4WD
warning light is illuminated, be sure to
place the 4WD shift switch in the 4L
position. If only the rear wheels are
spinning, this means that the transfer
has not switched to the 4L position
electrically.
If this situation occurs, contact a dealer or
road assistance service for help. If an
immediate service is not available, per-
form the following procedure to switch to
the 4L position manually and free the
vehicle.
CAUTION
Only perform this procedure in an
emergency.
If the vehicle is driven for a long
period of time over a long distance
with a component detached, foreign
material such as water, sand, etc.
may enter from the opening and this
may cause a malfunction in the
drivetrain system. After freeing a
vehicle that has become stuck, it is
recommended you contact a NISSAN
dealer for inspection and repair.
WARNING
.Ensure your safety before per-
forming the operations. The ve-
hicle may move unexpectedly.
. Place the ignition switch in the
OFF position, apply the parking
brake and let the vehicle cool
down.
. Do not perform the following
procedure immediately after
driving the vehicle. Parts such as
exhaust components, the trans- mission, etc. are very hot and
may cause a burn injury.
. Make sure that the parts that will
be operated as well as related
parts cool down before perform-
ing the operation.
. Burrs or projecting portions of
metal components may cause
unexpected injury to your fingers
or arms. Pay special attention in
regard to your safety while re-
moving and installing these
parts. Wear work gloves and pro-
tective arm covers.
CAUTION
While removing and installing the
parts, prevent the removed parts
from getting dirty with water, dirt or
sand. Protect the parts using a cover
such as a clean cloth, etc.

MANUAL SHIFTING (4WD models)

OPERATING PROCEDURE
Place the ignition switch in the OFF
position and apply the parking brake. Let
the vehicle cool down before performing
the following procedure.

4WD shift motor assembly
1. Check that the ignition switch is in theOFF position.
CAUTION
The following procedure includes the
removal of the electrical system
components. Therefore, make sure
that the ignition switch is in the OFF
position before proceeding.

4WD shift motor harness connector
2. Unlock the upper lockof the har-
ness connector of the 4WD shift motor
assembly, then remove the harness
connector.
3. Cover the connector to prevent it from getting dirty, and then fasten
the connector to the vehicle using a
suitable rope so that the connector
does not contact the exhaust muffler,
etc.

CAUTION
The connector must be fastened
securely. Not doing so may result in
damage to the connector due to
interference with other parts.

4. Remove the 4 boltsthat secure the
4WD shift motor using the wrench
that is equipped in the vehicle.
5. Remove the 4WD shift motor assem- bly.
CAUTION
Be careful not to allow the assembly
to contact water, dirt or sand.
SCE0962
6. Completely insert the wrench into the
internal gearof the transfer.
7. Fully turn the wrench clockwise
as
far as it will go. This shifts the transfer
to the 4L position.
8. Install the 4WD shift motor assembly. Securely tighten the 4 bolts using the
wrench.
CAUTION
.Do not connect the harness con-
nector of the 4WD shift motor
after the above procedure has
been performed.

.The 4 bolts are tightened to
temporarily install the 4WD shift
motor so that water, dirt or sand
does not enter inside the system.
Therefore, they should only be
tightened to the proper tighten-
ing torque. It is recommended
you contact a NISSAN dealer for
inspection and repair.
9. With the 4WD system in the 4L posi- tion, free the stuck vehicle. (See “Ve-
hicle recovery (freeing a stuck vehicle)”
(P.6-19) for details.)
CAUTION
After manually shifting the vehicle to
the 4L position, it is recommended
you contact a NISSAN dealer for
inspection and repair as soon as
possible.

the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-9) for wheel off-set
dimensions.
. Since the spare tire is not
equipped with the TPMS, when a
spare tire is mounted or a wheel
is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 1 minute. The light
will remain on after 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as possible. It is recommended you
visit a NISSAN dealer for these
services.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning. .
The use of retread tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias,
bias-belted or radial), and tread
pattern on all four wheels. Failure
to do so may result in a circum-
ference difference between tires
on the front and rear axles which
will cause excessive tire wear and
may damage the transmission,
transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
