6-16In case of emergency
When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations
for towing must be followed. Incorrect
towing equipment could damage your
vehicle. Towing instructions are available
from a NISSAN dealer. Local service op-
erators are familiar with the applicable
laws and procedures for towing. To
assure proper towing and to prevent
accidental damage to your vehicle,
NISSAN recommends that you have a
service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions.
WARNING
.Never ride in a vehicle that is
being towed.
. Never get under your vehicle after
it has been lifted by a tow truck.
CAUTION
.When towing, make sure that the
transmission, axles, steering sys-
tem and powertrain are in work-
ing condition. If any of these
conditions apply, dollies or a
flatbed tow truck must be used. .
Always attach safety chains be-
fore towing.
For information about towing your vehi-
cle behind a recreational vehicle (RV), see
“Flat towing” (P.10-29).
TOWING YOUR VEHICLE

VEHICLE RECOVERY (freeing a stuck
vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high
speed. This could cause them to
explode and result in serious in-
jury. Parts of your vehicle could
also overheat and be damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Attach the tow strap to the towing hook.
CAUTION
.Tow chains or cables must be
attached only to the main struc-
tural members of the vehicle or
the towing hooks. Otherwise, the
vehicle body will be damaged.
. Use the towing hook only to free
a vehicle stuck in sand, snow, mud, etc. Never tow the vehicle
for a long distance using only the
towing hook.
. The towing hook is under tre-
mendous force when used to free
a stuck vehicle. Never pull the
hook at an angle.
. Always pull the cable straight out
from the front or rear of the
vehicle.
. Pulling devices should be routed
so they do not touch any part of
the suspension, steering, brake or
cooling systems.
. Pulling devices such as ropes or
canvas straps are not recom-
mended for use in vehicle towing
or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstruc-
tions.
3. Turn the steering wheel right and left to clear an area around the front tires. 4. Slowly rock the vehicle forward and
backward.
.Shift back and forth between R(Reverse) and D (Drive).
.Apply the accelerator as little as possible to maintain the rocking
motion.
.Release the accelerator pedal be-
fore shifting between R and D.
.Do not spin the tires above 35 MPH(55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional tow-
ing service to remove the vehicle.
In case of emergency6-19

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.5-116).)
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.
FOUR-WHEEL DRIVE (4WD)
MANUAL SHIFTING (4WD models)

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to P (Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
, open the reservoir
tank cap and add coolant up to the MAX
level. If the reservoir tank is empty,
check the coolant level in the radiator
when the engine is cold. If there is
insufficient coolant in the radiator, fill the
radiator with coolant up to the filler
opening and also add it to the reservoir
tank up to the MAX level
.
Tighten the cap securely after adding
engine coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom- mended you visit a NISSAN dealer for
this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling
system repairs be performed by a NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
WARNING
.
To avoid the danger of being
scalded, never change the cool-
ant when the engine is hot.
. Never remove the radiator cap or
coolant reservoir cap when the
engine is hot. Serious burns could
be caused by high pressure fluid
escaping from the radiator.
. Avoid direct skin contact with
used coolant. If skin contact is
made, wash thoroughly with soap
or hand cleaner as soon as pos-
sible.
. Keep coolant out of reach of
children and pets. Engine coolant must be disposed of
properly. Check your local regulations.
