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
(MIL) 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
●Do not use E-15 or E-85 fuel in your
vehicle. For further information see the
“Fuel Recommendation” in the “Techni-
cal and consumer information” section
of this manual.

3. Touch the ignition switch with the IntelligentKey as illustrated. (A chime will sound.)
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
4. Push the ignition switch while depressing the brake pedal within 10 seconds after the
chime sounds. The engine will start.
NOTE: ● When the ignition switch is pushed to the
ACC or ON position or the engine is started
by the above procedure, the Intelligent Key
battery discharge indicator appears in the
vehicle information display even when the
Intelligent Key is inside the vehicle. This is
not a malfunction. To turn off the Intelligent
Key battery discharge indicator, touch the
ignition switch with the Intelligent Key again.
● If the Intelligent Key battery discharge indi-
cator appears, replace the battery as soon
as possible. See “Battery Replacement” in
the “Maintenance and do-it-yourself” sec-
tion.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and windshield-washer fluid
as frequently as possible, or at least when-
ever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is pushed to the ON
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual.

Shift lock release
If the battery charge is low or discharged, the
shift selector may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift selector button pushed.
It will be necessary to jump start or have your
battery charged, see “Jump starting” in the “In
case of emergency” section. Contact your
NISSAN dealer or a professional towing service.
To move the shift selector, complete the following
procedure:1. Push the ignition switch to the LOCK posi- tion. 2. Apply the parking brake.
3. Using a protective cloth on the tip ofa3mm
screwdriver, remove the shift lock release
cover.
● If available, a plastic trim tool can also be
used.
4. Insert the small screwdriver in the shift lock release slot and push down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the trans-
mission as soon as possible.WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Overdrive (O/D) OFF switch (if so
equipped)
When the O/D OFF switch is pushed with the
shift selector in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light” in the “Instruments
and controls” section of this manual.
Use the Overdrive off mode when you need im-
proved engine braking.
To turn off the Overdrive off mode, push the O/D
OFF switch again. The
indicator light will
turn off.

Starting and driving5-17

Each time the engine is started, or when the shift
selector is shifted to any position other than D
(Drive) , the Overdrive off mode will be automati-
cally turned off.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid temperature
protection mode. If the fluid temperature be-
comes too high (for example, when climbing
steep grades in high temperature with heavy
loads, such as when towing a trailer) , engine
power and, under some conditions, vehicle
speed will be decreased automatically to reduce
the chance of transmission damage. Vehicle
speed can be controlled with the accelerator
pedal, but the engine and vehicle speed may be
limited.
Fail-safe
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safesystem may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction Indicator Light
(MIL)” in the “Instrument and controls” sec-
tion. This will occur even if all electrical
circuits are functioning properly. In this
case, place the ignition switch in the OFF
position and wait for 10 seconds. Then
push the switch back to the ON position.
The vehicle should return to its normal op-
erating condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially care-
ful when driving. If necessary, pull to the
side of the road at a safe place and allow
the transmission to return to normal op-
eration, or have it repaired if necessary.
1. To engage, firmly depress the foot brake.
2. To release:
●Move the shift selector to the P (Park)
position
● Firmly depress the parking brake pedal
and it will release.
● Before driving, be sure the brake warning
light goes out.

WARNING
●The camera unit may not be able to
detect properly under the following
conditions:
– On roads where there are multiple parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; or lane mark-
ers covered with water, dirt, snow,
etc.
– On roads where the discontinued lane markers are still detectable.
– On roads where there are sharp curves.
– On roads where there are sharply contrasting objects, such as shad-
ows, snow, water, wheel ruts, seams
or lines remaining after road repairs.
(The LDW system could detect these
items as lane markers.)
– On roads where the traveling lane merges or separates.
– When the vehicle’s traveling direc- tion does not align with the lane
marker. – When the road surface is very dark
due to weak ambient light or im-
paired tail lamp.
● When driving on a curved road, warning
will be late on the outside of the curve.
BSW/LDW TEMPORARY DISABLED
STATUS
Under the following condition, the BSW and/or
LDW system is turned off temporarily, the BSW
light (white) and/or LDW light (white) will blink,
and either of the following message will appear in
the vehicle information display:
● “Trunk is open”
● “Washer fluid is low”
When the above conditions are corrected, the
BSW and/or LDW system will resume automati-
cally.
BSW/LDW AUTOMATIC
DEACTIVATION
When dirt, rain or snow cannot be removed by
the automatic washer and blower and accumu-
lates on the camera, making it impossible to
detect the vehicles or the lane markers, the BSW
and/or LDW system will be turned off automati-
cally. The BSW light (white) and/or LDW light (white) will blink, and the “Unavailable : Clean
rear camera” will appear in the vehicle information
display.
Action to take:
If the message appears, park the vehicle in a safe
place, clean the camera unit with a soft cloth.
Then turn off and restart the engine.
When the BSW and/or LDW system malfunc-
tions, they will be turned off automatically, the
BSW light (orange) and/or LDW light (orange)
will illuminate and “Malfunction: Please see own-
ers manual” will appear in the vehicle information
display.
Action to take:
Stop the vehicle in a safe location, turn off and
restart the engine. If the BSW light (orange)
and/or the LDW light (orange) continues to illu-
minate, have the BSW and/or LDW system
checked by a NISSAN dealer.
Starting and driving5-25

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
much harder to operate. Have the
power steering system checked by a
NISSAN dealer.
The power steering system is designed to pro-
vide power assistance while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still per-
formed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the igni-
tion switch to the OFF position. The temperature of the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to over-
heat.
You may hear a noise from the front of the vehicle
when the steering wheel is operated. This is a
normal operational noise and is not a malfunction.
If the power steering warning light illuminates
while the engine is running, it may indicate the
power steering system is not functioning properly
and may need servicing. Have the power steering
system checked by a NISSAN dealer.
When the power steering warning light illumi-
nates with the engine running, the power assist
for the steering will cease operation but you will
still have control of the vehicle. At this time,
greater steering efforts are required to operate
the steering wheel, especially in sharp turns and
at low speeds.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
POWER STEERING
BRAKE SYSTEM
Starting and driving5-31

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.When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle 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 output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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 cannot prevent loss of
vehicle control in all driving situations.
