●Keep your engine tuned up.
● Follow the recommended scheduled main-
tenance.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
● Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(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 facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do 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.

5-50Starting and driving

●Do 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 or warning
message turn 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 lever to the N position with the

4WD shift switch to 2WD.
● If the warning light or warning message
is still on after the above operation,
have your vehicle checked as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
● The transfer case may be damaged if
you continue driving with the warning
light or warning message on. 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. For
additional information, refer to “Electronic locking
rear differential (E-Lock) system switch” in the
“Instruments and controls” section of this manual.
Once the system fully engages, the indicator 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
light
illuminates when the E-Lock system is on.
WARNING
● Never 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.
● Use the E-lock system only in an emer-
gency when it is not possible to free a
struck vehicle even when using 4LO.
Never use the E-Lock system on a slip-
pery road surface such as snow or ice
surface. 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.
● Observe the above warnings. Other-
wise, loss of normal steering control
may result. This may result in an acci-
dent and serious personal injury.

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to “Tire and loading
information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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 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 brake
pedal. 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. It is recommended that you visit a
NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above3-6mph(5
- 10 km/h). The speed varies according to road
conditions.
Starting and driving5-55

Do not attach stickers (including transparent ma-
terial) , install accessories or apply additional
paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you con-
sult a NISSAN dealer if the area around the sonar
sensors is damaged due to a collision.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 key fob (if so
equipped) .
ANTIFREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
antifreeze to assure proper winter protection. For
additional information, refer to “Engine cooling
system” in the “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 additional information, refer to “Bat-
tery” in the “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 additional information, refer to “Changing
engine coolant” in the “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. It is
recommended that you visit a NISSAN
dealer for the tire type, size, speed rating and
availability information.
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. 3. Tire chains may be used. For additional in- formation, refer to “Tire chains” in the “Do-it-
yourself” section of this manual.
COLD WEATHER DRIVING
Starting and driving5-65

CAUTION
●Do not push start this vehicle. The
three-way catalyst or engine may be
damaged.
● Automatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
● Three way catalyst equipped models
should not be started by pushing since
the three way catalyst may be damaged.
● Never try to start the vehicle by towing
it; when the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
WARNING
● Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps: 1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed. 3. If engine overheating is caused by climbing a
long hill on a hot day, run the engine at a fast
idle (approximately 1,500 rpm) until the tem-
perature gauge indication returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radiator
before opening the hood. If steam or coolant
is escaping, turn off the engine. Do not open
the hood further until no steam or coolant
can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
6. 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.7. 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. It
is recommended that you visit a NISSAN
dealer for this service. When towing your vehicle, all jurisdictional 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 operators are gen-
erally familiar with the applicable laws and proce-
dures 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 ser-
vice operator carefully read the following precau-
tions:
WARNING
●
Never ride in a vehicle that is being
towed.
● Never get under your vehicle after it has
been lifted by a tow truck.
● If your vehicle has front recovery hooks
as original factory equipment, do not
remove or modify them. If it was not
equipped with front recovery hooks, do
not install them. Either action could af-
fect proper operation of the front air
bag system resulting in injury or death.
CAUTION
● When towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any of these conditions apply, dollies or
a flatbed tow truck must be used.
● Always attach safety chains before
towing.
For additional information about towing your ve-
hicle behind a Recreational Vehicle (RV) , refer to
“Flat towing” in the “Technical and consumer
information” section of this manual.
