4WD shift indicator light
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.● The 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. ●
If 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.

The 4WD warning light is located in the meter. The 4WD warning light comes on when the igni-
tion switch is turned to ON. It turns off soon after
the engine is started.
If any malfunction occurs in the 4WD system
when the ignition 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 2 seconds) . Change the
4WD shift switch into 2WD and do not drive fast.
CAUTION
●
If the warning light comes on or blinks
slowly during operation, have your ve-
hicle checked by a NISSAN dealer as

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 vehicle in front of
you. Ultimately, the driver is respon-
sible 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 “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery 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 by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.
Starting and driving5-35

will sound for only 3 seconds. Once the system
detects an object approaching, the tone will
sound again.
The RSS automatically turns on when the shift
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 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 mal-
function in the RSS.
Keep the RSS sensors (located on the rear bum-
per fascia) free from snow, ice and large accumu-
lations 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 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 “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 additional information, refer to “Bat-
tery” in the “Maintenance and do-it-yourself” sec-
tion 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 “Maintenance and do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide 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 4 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 jurisdic-
tions 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.
COLD WEATHER DRIVING
Starting and driving5-41

●If 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 accident
and could result in serious personal in-
jury. Check the tire pressure for all 4
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.
● When a spare tire is mounted or a wheel
is replaced, 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. ●
Replacing tires with those not originally
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 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. Shift the manual transmission into R
(Reverse) , or the automatic transmission
into 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.
WARNING
●Make sure the parking brake is securely
applied and the manual transmission is
shifted into R (Reverse) , or the auto-
matic 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 profes-
sional road assistance.
6-4In case of emergency

3. Get out of the vehicle. Look and listen forsteam 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.
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 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.
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.

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money;
however, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition as well as its emis-
sions 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-
hicles
before they 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 economical 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” in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood
Check that the doors
