*1: Before moving the transmission selector or shift lever from neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedure is completed and the transfer gear is correctly
set in the 4LO position. If the vehicle is shifted into gear before the indicator is on steady, the transfer gear may grind, not engage correctly or stay in the neutral position.
- If the 4WD warning light illuminates, perform the following procedure to return the transfer case to correct operating condition.
1. Turn off the engine by turning the ignition switch9OFF9.
2. Start the engine.
- Check that the 4WD warning light turns off. If the 4WD warning light illuminates, have the system checked by a NISSAN dealer.
3. Apply the parking brake, for automatic transmission vehicles, depress the brake pedal and move the transmission selector to Neutral position. Formanual transmission vehicles, move the transmission shift lever
to Neutral position.
4. With the brake pedal depressed on automatic transmission vehicles or with the clutch pedal depressed on manual transmission vehicles, move the 4WDshift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the transmission selector or transmission shift lever from Neutral position.
*2: While changing in and out of 4LO, the ignition key must be ON and the vehicle’s engine must be running for a shift to take place and for the indicator lights (4WD shift and 4LO position indicator) to be operable.
Otherwise, the shift will not take place and no indicator lights will be on or flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shift the 4WD shift switch to 4LO. The
indicator light (if so equipped) will also turn on when 4LO is selected. See “Vehicle dynamic
control system” later in this section.

The 4WD shift indicator light is located in the
odometer 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.cIf the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
If the 4WD shift indicator light indication
changes to 2WD when the 4WD shift
switch is shifted to the 4H position at low
ambient temperatures, the 2WD mode
may be being engaged due to malfunc-
tioning 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.

cDrive the vehicle at speeds above 10 mph
(15 km/h) for at least 10 minutes.
cThe VDC OFF indicator light should go off
indicating the traction control system is op-
erational.
cIf you interrupt the reset procedure by turn-
ing the ignition off, you will need to restart
the reset procedure.
If after driving the vehicle for more than 10 min-
utes and theSLIPand
lights remain illumi-
nated in the instrument panel, have the vehicle
dynamic control system checked by a NISSAN
dealer.
If the vehicle is operated with the vehicle dynamic
control system off using the VDC OFF switch,
most VDC functions will be turned off. The VDC
system will still try to transfer power from a slip-
ping drive wheel to one with more traction when
the VDC system switch is OFF. The Slip indicator
will flash if wheel spin is detected. The ABS will
still operate with the VDC system off.
When the VDC system is operating, 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 the VDC system is working properly.
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 reverseat 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 normal and is not an
indication of a malfunction.
WARNING
cThe vehicle dynamic control system is
designed to help improve driving stabil-
ity but does not prevent accidents due
to abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the vehicle dynamic control
system may not operate properly and
the vehicle dynamic control off indica-
tor light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars
and bushings are not NISSAN approved
for your vehicle or are extremely dete-
riorated the vehicle dynamic controlsystem may not operate properly. This
could adversely affect vehicle handling
performance, and the VDC OFF indica-
tor light may come on.
cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the vehicle dynamic control system may
not operate properly and the VDC OFF
indicator light may come on. Do not
drive on these types of roads.
cWhen driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the vehicle dynamic control off
indicator light may illuminate. This is
not a malfunction. Restart the engine
after driving onto a stable surface
cIf wheels or tires other than the recom-
mended ones are used, the vehicle dy-
namic control system may not operate
properly and the vehicle dynamic con-
trol off indicator light may come on.
cThe vehicle dynamic control system is
not a substitute for winter tires or tire
chains on a snow covered road.

The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the
driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a hill.
Hill start assist will operate automatically under
the following conditions:
cThe selector lever is shifted to a forward or
reverse gear.
cThe vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds. After 2
seconds the vehicle will begin to roll back and hill
start assist will stop operating completely.
Hill start assist will not operate when the selector
lever is shifted to N or P or on a flat and level road.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. 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.

WARNING
cIf the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Serious vehicle
damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pressure
for all four tires. Adjust the tire pressure
to the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If you have
a flat tire, replace it with a spare tire as
soon as possible.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.

3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time when the coolant
temperature is high.6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, NISSAN recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it has
been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any unit is damaged, dollies must be
used.
cAlways attach safety chains before
towing.

Your new NISSAN has been designed to have
minimum maintenance requirements with longer
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your NIS-
SAN’s good mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide.” You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hiclesbeforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hoodCheck that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
