*1: Before moving the automatic transmission shift lever from neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WDshift
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 light illuminates, have the system checked by a NISSAN dealer.
3. Apply the parking brake, depress the brake pedal and move the automatic transmission shift selector lever to Neutral position.
4. With the brake pedal depressed, move the 4WD shift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the automatic transmission shift selector 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
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.cIf the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
cIf the 4WD shift indicator light indica-
tion 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
malfunctioning drive system. If the indi-
cator does not return to normal and the
4WD warning light comes on, have the
system checked by the nearest NISSAN
dealer.

The 4WD warning light is located in the meter.
The 4WD warning light comes on when the key
switch is turned to ON. It turns off soon after the
engine is started.
If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
cIf the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by a NISSAN
dealer as soon as possible.
cShifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.

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, stop the vehicle,
move the automatic transmission
shift selector lever to the N position
with the brake 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
engage 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.WARNING
cNever leave the E-Lock system ON
when driving on paved or hard-surfaced
roads. Turning the vehicle may result in
the rear wheels slipping and result in an
accident and personal injury. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.
cUse the E-Lock system only when free-
ing a stuck vehicle. Try the 4LO position
before using the E-Lock system. Never
use the E-Lock system on a slippery
road surface such as snow or ice sur-
face. Using the E-Lock system when
driving in these road conditions may
cause unexpected movement of the ve-
hicle during engine braking, accelerat-
ing or turning, which may result in an
accident and serious personal injury.

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .
When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
This action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brakepedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.cABLS is a form of traction control using
sensors from the Anti-lock Brake System
(ABS) to transfer power from a slipping drive
wheel to a wheel with more traction. The
ABLS system applies braking to the slipping
wheel, which helps redirect power to an-
other wheel.
cOn 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system will operate for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
cThe ABLS system is always ON unless the
system detects brake pad overheating. If
high brake pad temperature is detected, it
will turn OFF, but normal brake function will
continue. ABLS will function even when the
VDC system (if so equipped) is turned OFF.
WARNING
The ABLS system provides increased trac-
tion, but will not prevent accidents due to
abrupt steering operation or by careless
driving or dangerous driving practices.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces, and always drive
carefully.

will sound for only three seconds. Once the sys-
tem detects an object approaching, the tone will
sound again.
The RSS automatically turns on when the shift
selector lever is placed in R (Reverse) and the
ignition is ON. The RSS OFF switch on the
instrument panel allows the driver to turn the RSS
on and off. To turn the RSS off, the ignition must
be ON, and the shift selector lever in R (Reverse) .
An indicator light on the switch will illuminate
when the system is turned off. If the indicator light
illuminates when the RSS is not turned off, it may
indicate a failure in the RSS.
Keep the RSS sensors (located on the rear
bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the RSS.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.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate and warn you of it by the low tire pressure
warning light. This system will activate only when
the vehicle is driven at speeds above 16 MPH
(25 km/h) . For more details, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, “Tire
pressure information” in the “Display screen,
heater, air conditioner and audio systems” sec-
tion and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section.
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. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion 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, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Move the shift selector lever to P
(Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic
and clear of the vehicle.

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.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.
