Warning messageWarning message comes on when:
Vehicle information display
4WD Error: See Owner’s Manual There is a malfunction in the 4–Wheel Drive system
FRT & RR tire size difference: See Owner’s Manual The difference in wheel rotation is large
CAUTION
• If the warning message comes on
during operation or rapidly af ter
stopping the vehicle for a while, have
your vehicle checked as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• Shif ting between 4H and 4LO is not
recommended when the 4WD warn-
ing message turns on.
• When the warning message comes
on, the 2WD mode may be engaged
even if the 4WD shif t switch is in 4H.
Be especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be en-
gaged even if the 4WD shif t switch is
shif ted.
• Do not drive the vehicle in the 4H or
4LO 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 message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
Starting and driving5-111

–In the 4LO position, stop the ve-
hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
• If the warning message is still on af-
ter 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 warn-
ing message on. The E-Lock system can provide additional
traction and should only be used when a
vehicle has become or is becoming stuck.
This system operates by electronically
“locking” the two rear drive wheels to-
gether, 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 ve-
hicles).
When added traction is required, activate
the E-Lock system by pushing the switch
on. For additional information, see “Elec-
tronic locking rear differential (E-Lock) sys-
tem switch” (P. 2-59). Once the system fully
engages, the indicator light in the instru-
ment panel will remain on. When the sys-
tem is activated, both rear wheels will en-
gage, providing added traction.
The rear wheels may momentarily slip or
move to engage the system, and the sys-
tem 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 Braking System (ABS) is dis-
abled and the ABS warning light illumi-
nates 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 per-
sonal injury. Af ter using the E-Lock
system to free the vehicle, turn the
system off.
• Use the E-Lock system only in an
emergency when it is not possible to
free a stuck vehicle even when using
4LO. Never use the E-Lock system on
a slippery road surface such as snow
or ice surface. Using the E-Lock sys-
tem when driving in these road con-
ditions may cause unexpected
movement of the vehicle during en-
gine braking, accelerating 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 ac-
cident and serious personal injury.

DIFFERENTIAL (E-Lock) SYSTEM (if
so equipped)
5-112Starting and driving

Self-test feature
The Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 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.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert,
drive safely and be in control of the ve-
hicle at all times. • 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 system applies
braking to the slipping wheel, which helps
redirect power to the other wheel.
• On 4–Wheel Drive (4WD) models the ABLS system operates in both 4H and 4LO
modes. If 4WD mode is engaged, the
ABLS system operates for both drive ax-
les. 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 Dynamic
Control system is turned off.
• The ABLS system does not operate if both wheels on a drive axle are slipping.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
Starting and driving5-117

WARNING
• The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering op-
eration or by careless driving or dan-
gerous driving practices. Reduce ve-
hicle speed and be especially careful
when driving and cornering on slip-
pery surfaces. Always drive carefully.
• Do not modif y the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN approved for your vehicle
or are extremely deteriorated, the
ABLS system may not operate prop-
erly. This could adversely affect ve-
hicle handling performance, and the
slip indicator light may illuminate.
• If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the ABLS sys-
tem may not operate properly and
the slip indicator light may
illuminate. •
If wheels or tires other than the
NISSAN recommended ones are
used, the ABLS system may not oper-
ate properly and the slip indicator
light may illuminate. The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
• Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power
is transferred to a non-slipping drive
wheel on the same axle.
• Controls brake pressure and engine out- put to reduce drive wheel slip based on
vehicle speed (traction control function).
• If the 4WD transfer case is shif ted into 4LO the
indicator light will come on and
the VDC system will be turned off. For
additional information, see “Using
4-Wheel Drive (4WD)” (P. 5-105).
• Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:– Understeer (vehicle tends to not follow the steered path despite increased
steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations.

WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.
7. Af ter the engine cools down, check the coolant level in the engine coolant reser-
voir 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 in-
structions are available from a NISSAN
dealer. Local service operators are gener-
ally familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, NISSAN recommends hav-
ing a service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle af ter it
has been lif ted by a tow truck.
• If your vehicle has front recovery
hooks as original factory equipment,
do not remove or modif y them. If it
was not equipped with front recov-
ery hooks, do not install them. Either
action could affect proper operation
of the front air bag system resulting
in injury or death.
CAUTION
• When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-
tion. Use dollies or flatbed if any of
the listed systems are not working.
• Always attach safety chains before
towing.
For additional information about towing
your vehicle behind a Recreational Vehicle
(RV), see "Flat towing for 2-Wheel Drive
(2WD) vehicle" (P. 10-55) or "Flat towing for
4-Wheel Drive (4WD) vehicle" (P. 10-55).
TOWING RECOMMENDED BY
NISSAN
NISSAN recommends towing your vehicle
based upon the type of drivetrain. For addi-
tional information, refer to the diagrams in
this section to ensure that your vehicle is
properly towed.
TOWING YOUR VEHICLE
In case of emergency6-13

Four-Wheel Drive (4WD) models
with automatic transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on a flatbed truck as illustrated.
CAUTION
Never tow 4WD models equipped with
an automatic transmission with any of
the wheels on the ground as this may
cause serious and expensive damage
to the transfer case and transmission.
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
LCE2141
6-14In case of emergency

•Always use tires of the same type,
size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) sys-
tem and 4WD system to malfunction
resulting in personal injury or death,
excessive tire wear and may damage
the transmission and differential
gears.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S on the tire sidewall.
Snow tires have better snow traction than
All Season tires and may be more appropri-
ate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, stud-
ded 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 CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tire
size. Other types may damage your vehicle.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain
must be secured or removed to prevent
the possibility of whipping action damage
8-42Do-it-yourself

•Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” (P. 8-35).
WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, 4WD,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speedom-
eter calibration, headlight aim and
bumper height. Some of these ef-
fects may lead to accidents and
could result in serious personal
injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four tires, install
the new tires on the rear axle. Placing
new tires on the front axle may cause
loss of vehicle control in some driving
conditions and cause an accident
and personal injury. •
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
see “Wheels and tires” (P. 10-9).
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain 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 this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
Do-it-yourself8-45

Your vehicle may be equipped with a full
size spare that is a different size or brand
than the tires originally installed on the ve-
hicle. This full size spare tire is intended for
temporary use only and should be re-
placed at the first opportunity.
Observe the following precautions if the
FULL SIZE TEMPORARY USE ONLY spare tire
must be used. Otherwise, your vehicle
could be damaged or involved in an acci-
dent:
WARNING
To help reduce the risk of a crash which
may result in personal injury or death:
• The TEMPORARY FULL SIZE spare tire
should be used for emergency use
only. It should be replaced with the
standard tire at the first opportunity
to avoid possible tire or differential
damage.
• Drive carefully while the TEMPORARY
FULL SIZE spare tire is installed. Avoid
sharp turns and abrupt braking while
driving. The vehicle driving perfor-
mance may be affected when driving
on wet or snow covered roads. •
When the TEMPORARY FULL SIZE
spare is installed, the following sys-
tems may not work correctly:
– Tire Pressure Monitoring System
(TPMS)
– Vehicle Dynamic Control (VDC)
System
• Periodically check the TEMPORARY
FULL SIZE spare tire inflation pres-
sure. Always keep the TEMPORARY
FULL SIZE inflated to the pressure
specification shown on the Tire and
Loading Information label.
• With the TEMPORARY FULL SIZE spare
tire installed do not drive the vehicle
at speeds faster than 50 mph (80
km/h).
• When driving on roads covered with
snow or ice, the TEMPORARY FULL
SIZE spare tire should be used on the
front wheels and the original tire
used on the rear wheels. Use tire
chains only on the drive wheels.
• Do not use the TEMPORARY FULL SIZE
spare tire on other vehicles.
• Do not use more than one TEMPO-
RARY FULL SIZE spare tire at the same
time. •

• Customer can identif y TEMPORARY
FULL SIZE spare tire condition by
checking the Tire and loading infor-
mation label located on the B-pillar.
CAUTION
• Do not use tire chains on a TEMPO-
RARY FULL SIZE spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Use of the TEMPORARY FULL SIZE
spare tire on a vehicle that has tires
larger than were originally equipped
can affect the 4WD system. This may
result in a circumference difference
between tires on front and rear axles
which can cause the 4WD system to
automatically place the vehicle in
2WD and flash the 4WD light. When
the TEMPORARY FULL SIZE spare tire
is replaces with a tire that matches all
other tires on the vehicle, and all tires
are properly inflated the 4WD system
will operate normally
