4WD shif t indicator
The 4WD shif t indicator is located in the
vehicle information display.
While the engine is running, the 4WD shif t
indicator will illuminate the position se-
lected by the 4WD shif t switch.∙ The 4WD shif t indicator may come on
while shif ting from one drive mode to
the other. When the shif ting is com-
pleted, the 4WD shif t indicator will
stay on. ∙ If the 4WD vehicle information display
warning message comes on, the 4WD
indicator goes out.
CAUTION
∙ If the 4WD shif t indicator indicationchanges to 2WD when the 4WD shif t
switch is shif ted to the 4H position at
low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the in-
dicator does not return to normal and
the 4WD vehicle information display
warning message comes on, have the
system checked. It is recommended
that you visit a NISSAN dealer for this
service.

5-50Starting and driving

– In the 4H position, shif t the 4WDshif t switch to 2WD.
– 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 ve-
hicle 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
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, 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 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 personal
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 system
when driving in these road conditions
may cause unexpected movement of
the vehicle during engine braking, ac-
celerating or turning, which may re-
sult in an accident and serious per-
sonal 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.

so equipped)
5-52Starting and driving

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit on vehicles equipped with a trip
computer (if so equipped), and the Tire
Pressure Low — Add Air warning appears in
the vehicle information display (if so
equipped), one or more of your tires is sig-
nificantly 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 be-
ing driven with low tire pressure, the TPMS
will activate 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 addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.
WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ If the low tire pressure warning light illuminates 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, TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately one minute. The light will re-
main on af ter one 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.

CAUTION
∙ Af ter wiper blade replacement, returnthe wiper arm to its original position;
otherwise it may be damaged when
the hood is opened.
∙ Make sure the wiper blades contact the glass; otherwise the arms may be
damaged from wind pressure.
Be careful not to let anything get into the
washer nozzle
D. This may cause clogging
or improper windshield–washer operation.
If something gets into the nozzle, remove it
with a needle or small pin
C. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard.

2. Location mark
WARNING
∙ Tires should be periodically in- spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced. ∙ The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
∙ Tires degrade with age and use. Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
∙ Improper service of the spare tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is recom-
mended 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 Information”
(Canada) in the Warranty Infor-
mation 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” in the “Technical and con-
sumer information” section of this manual.
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 Dynamic
Control (VDC) system, ground clear-
ance, body-to-tire clearance, tire
chain clearance, speedometer cali-
bration, headlight aim and bumper
height. Some of these effects may
lead to accidents and could result in
serious personal injury.
