High beam indicator light(blue)
This blue light comes on when the headlight high
beams are on and goes out when the low beams
are selected.
The high beam indicator light also comes on
when the passing signal is activated.
Hill descent control system onindicator light (if so equipped)
When the ignition switch is placed in the ON
position, this light comes on briefly and then turns
off.
The light comes on when the hill descent control
system is activated.
If the hill descent control switch is on and the
indicator light blinks, the system is not engaged.
If the indicator light does not come on or blink
when the hill descent switch is on, the system
may not be functioning properly. Have the system
checked by a NISSAN dealer.
For additional information, see “Hill descent con-
trol switch” later in this section and “Hill descent
control system” in the “Starting and driving” sec-
tion of this manual.
Malfunction Indicator Light(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The Malfunction Indicator Light may also come
on steady if the fuel-filler cap is loose or missing,
or if the vehicle runs out of fuel. Check to make
sure the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gallons
(11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual. Operation
The Malfunction Indicator Light will come on in
one of two ways:
● Malfunction Indicator Light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if
the LOOSE FUEL CAP warning message is
displayed in the odometer. If the fuel-filler
cap is loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a few
driving trips. If the
light does not turn
off after a few driving trips, have the vehicle
inspected by a NISSAN dealer. You do not
need to have your vehicle towed to the
dealer.
● Malfunction Indicator Light blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH (72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.

Turn signal/hazard indicatorlights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
Vehicle Dynamic Control(VDC) OFF indicator light
(if so equipped)
This indicator light comes on when the Vehicle
Dynamic Control off switch is pushed to OFF, the
transfer case is in the 4LO position (
model) , or when the Vehicle Dynamic Control
system is not functioning properly. This indicates
the Vehicle Dynamic Control system is not oper-
ating.
Push the Vehicle Dynamic Control off switch
again or restart the engine and the system will
operate normally. See “Vehicle Dynamic Control
(VDC) system” in the “Starting and driving” sec-
tion of this manual.
The Vehicle Dynamic Control light also comes on
when you turn the ignition key to the ON position.
The light will turn off after about 2 seconds if the
system is operational. If the light stays on or
comes on along with the SLIP indicator light while you are driving, have the Vehicle Dynamic
Control system checked by a NISSAN dealer.
If the battery is removed or discharged, the Ve-
hicle Dynamic Control system is disabled and the
VDC indicator light will not turn off after 2 sec-
onds when the ignition switch is turned to the ON
position. To reset the system, you must perform
the reset procedure. Refer to “Vehicle Dynamic
Control (VDC) system” in the “Starting and driv-
ing” section of this manual.
If the light does not go off after performing the
reset procedure, have the traction control system
checked by a NISSAN dealer.
While the Vehicle Dynamic Control system is
operating, you might feel slight vibration or hear
the system working when starting the vehicle or
accelerating, but this is normal.
The VDC system will be disabled and the VDC
light will illuminate when the electronic locking
rear differential (E-lock) system switch (if so
equipped) is turned on and the E-lock system is
engaged. If the E-lock system disengages or the
switch is turned off, the VDC system will be
enabled and the VDC light will turn off.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a disc brake pad requires replacement, it
makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the key is left in the ignition switch. Remove
the key and take it with you when leaving the
vehicle.

FUEL-FILLER CAP
WARNING
●Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
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
after 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 emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
malfunction indicator light
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. – Keep the pump nozzle in contact
with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●The LOOSE FUEL CAP warning mes-
sage will be displayed if the fuel-filler
cap is not properly tightened. Failure to
tighten the fuel-filler cap properly after
the LOOSE FUEL CAP warning message
is displayed may cause the
Mal-
function Indicator Light (MIL) to
illuminate.LPD0263

THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants. ●
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
all 4 tires to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
Starting and driving5-3

●Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
● Always drive with the floor mats in
place as the floor may become hot.
● Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
● Do not drive beyond the performance
capability of the tires, even with 4WD
engaged (if so equipped) .
● 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.
● Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
● If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same
speeds as passenger cars. Failure to
operate this vehicle correctly could re-
sult in loss of control and/or a rollover
accident. ●
Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
● Be sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
● Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “NISSAN Service and
Maintenance Guide.”
