main on as long as the switch is on. 3. When the seat is warmed or before you
leave the vehicle, be sure to turn the
switch off.
WARNING
Do not use or allow occupants to use
the seat heater if you or the occupants
cannot monitor elevated seat tempera-
tures or have an inability to feel pain in
body parts that contact the seat. Use of
the seat heater by such people could
result in serious injury.
CAUTION
∙ Do not use the seat heater for ex-tended periods or when no one is us-
ing the seat.
∙ Do not put anything on the seat which insulates heat, such as a blanket,
cushion, seat cover, etc. Otherwise,
the seat may become overheated.
∙ Do not place anything hard or heavy on the seat or pierce it with a pin or
similar object. This may result in dam-
age to the heater.
∙ Any liquid spilled on the heated seat should be removed immediately with
a dry cloth. ∙ When cleaning the seat, never use
gasoline, benzine, thinner, or any
similar materials.
∙ If any malfunctions are found or the heated seat does not operate, turn

WARNING
Pay special attention to your surround-
ings when using the clutch interlock
switch. The vehicle will move forward or
backward according to the gear
selected.
The clutch interlock (clutch start) switch
allows for starting the engine without de-
pressing the clutch pedal. This feature
helps you restart the engine if it stops un-
der difficult conditions. (For example, the
engine stops on a steep hill and a slight
movement forward or backward might be
dangerous.) To use the clutch interlock switch:
1. Set the parking brake.
2. Depress the brake pedal with your right foot.
3. Place your lef t foot on the brake pedal and release the parking brake.
4. Turn the ignition switch to the ON posi- tion.
5. Push and release the clutch interlock switch. The CANCEL light on the switch
will illuminate.
6. Turn the ignition to the START position to start the engine and, at the same
time, depress the accelerator pedal
with your right foot. As the vehicle be-
gins to move, take your lef t foot off the
brake. Once the engine has started, the
clutch interlock switch CANCEL light
shuts off. Do not use the interlock
switch to start the engine under nor-
mal driving conditions.
WARNING
The Rear Sonar System is a conve-
nience but it is not a substitute for
proper backing. Always turn and check
that it is safe to do so before backing up.
Always back up slowly.
The RSS (if so equipped) is active when the
ignition switch is placed in the ON position
and the shif t lever is in R (Reverse).
When sensors detect obstacles within 6 f t
(1.8 m) of the rear bumper, a beeping tone is
emitted.

WARNING
∙ Make sure the hood is completelyclosed and latched before driving.
Failure to do so could cause the hood
to fly open and result in an accident.
∙ If you see steam or smoke coming from the engine compartment, to
avoid injury do not open the hood.
FUEL-FILLER CAP
WARNING
∙ Gasoline is extremely flammable andhighly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames or
sparks near the vehicle when
refueling. ∙ Do not attempt to top off the fuel tank
af ter the fuel pump nozzle shuts off
automatically. Continued refueling
may cause fuel overflow, resulting in
fuel spray and possibly a fire.
∙ Use only an original equipment type fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious mal-
function and possible injury. It could
also cause the
Malfunction Indi-
cator Light (MIL) to come on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.
∙ Do not fill a portable fuel container in the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.

Pre-driving checks and adjustments3-11

If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, coolant, brake and clutch fluid (if so
equipped), and windshield-washer fluid
as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten the seat belt and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the key is placed in the ON posi-
tion. For additional information, refer to
“Warning lights, indicator lights and au-
dible reminders” in the “Instruments
and controls” section of this manual. 1. Apply the parking brake.

WARNING
∙ For 4WD equipped vehicles, do not at-tempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
∙ Do not attempt to test a 4WD equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing), or similar equipment even if
the other two wheels are raised off the
ground. Make sure you inform test fa-
cility personnel that your vehicle is
equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drive-
train damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
CAUTION
∙ Do not drive the vehicle in the 4H or4LO position on dry hard surface
roads. Driving 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 sur-
face roads:
– In the 4H position, shif t the 4WD shif t switch to 2–Wheel Drive
(2WD).
– In the 4LO position for automatic transmission vehicles, stop the ve-
hicle and shif t the shif t lever to the
N (Neutral) position with the brake
pedal depressed and shif t the 4WD
shif t switch to 2WD.
– In the 4LO position for manual transmission vehicles, stop the ve-
hicle and shif t the shif t lever to the
N (Neutral) position with the clutch
pedal depressed and shif t the 4WD
shif t switch to 2WD. ∙ If the warning light is still on af ter the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended that you visit a NISSAN
dealer for this service.
TRANSFER CASE SHIFTING
PROCEDURES

Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (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 for-
ward or reverse. When the self-test occurs,
you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal
and does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS warning
light on the instrument panel. The brake sys-
tem then operates normally but without
anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds above3-6mph(5-
10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving. ∙ The ABLS system uses automatic brak-
ing to transfer power from a slipping
drive wheel to the wheel on the same
axle with more traction. The ABLS sys-
tem applies braking to the slipping
wheel, which helps redirect power to
the other wheel.
∙ On 4–Wheel Drive models the ABLS sys- tem operates in both 4H and 4LO
modes. If 4WD mode is engaged, the
ABLS system operates for both drive
axles. On 2–Wheel Drive vehicles, the
ABLS system operates on the drive axle
only.
∙ The ABLS system is always on. In some conditions, the system may automati-
cally turn the ABLS system off. If the sys-
tem is automatically turned off, normal
brake function will continue. ABLS will
function even when the Vehicle Dy-
namic Control system is turned off.
∙ The ABLS does not operate if both wheels on a drive axle are slipping.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
Starting and driving5-37

∙ The system is designed as an aid tothe driver in detecting large station-
ary objects to help avoid damaging
the vehicle. The system will not detect
small objects below the bumper, and
may not detect objects close to the
bumper or on the ground.
∙ If your vehicle sustains damage to the rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate mea-
surement of obstacles or false alarms.
The RSS sounds a tone to warn the driver of
obstacles near the rear bumper when the
shif t lever is in R (Reverse). The system may
not detect objects at speeds above 3 mph
(5 km/h) and may not detect certain angu-
lar or moving objects.
The RSS detects obstacles up to 5.9 f t
(1.8 m) from the rear bumper with a de-
creased coverage area at the outer cor-
ners of the bumper (refer to the illustration
for approximate zone coverage areas). As
you move closer to the obstacle, the rate of
the tone increases. When the obstacle is
less than 10 in (25.0 cm) away, the tone will
sound continuously. If the RSS detects a
stationary or receding object further than
10 in (25.0 cm) from the side of the vehicle, the tone will sound for only 3 seconds.
Once the system detects an object ap-
proaching, the tone will sound again.
The RSS automatically turns on when the
shif t 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 shif t 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
malfunction 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 sen-
sors 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 in-
serting it into the key hole or use the re-
mote keyless entry key fob (if so equipped).
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
COLD WEATHER DRIVING
Starting and driving5-43

∙ If the low tire pressure warning lightilluminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
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 pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light still
illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
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. Shif t the manual trans-
mission into R (Reverse), or the auto-
matic transmission into P (Park).
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assis-
tance personnel that you need assis-
tance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
∙ Make sure the parking brake is se-curely applied and the manual trans-
mission is shif ted into R (Reverse), or
the automatic transmission into P
(Park).
∙ Never change tires when the vehicle is on a slope, ice or slippery areas. This is
hazardous.
∙ Never change tires if oncoming traffic is close to your vehicle. Wait for pro-
fessional road assistance.
