To lock, close the fuel-filler door securely and
lock the doors.
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. ●
The LOOSE FUEL CAP warning will ap-
pear if the fuel-filler cap is not properly
tightened. It may take a few driving trips
for the message to be displayed. Failure
to tighten the fuel-filler cap properly
after the LOOSE FUEL CAP warning ap-
pears may cause the
Malfunction
Indicator Light (MIL) to illuminate.
● Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate.
If the
light illuminates because
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 in-
spected by a NISSAN dealer.
● For additional information, see the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
in this manual.
● If fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
3-28Pre-driving checks and adjustments

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
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat 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
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

●Failure to operate this vehicle correctly
could result 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 front
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.”WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pushed 3 consecu-
tive times in quick succession or the igni-
tion switch is pushed and held for more
than 2 seconds.) If the engine stops while
the vehicle is being driven, this could lead
to a crash and serious injury.
When the ignition switch is pushed without de-
pressing the brake pedal, the ignition switch will
illuminate.
Push the ignition switch center:● once to change to ACC.
● two times to change to ON.
● three times to return to OFF.
The ignition switch will automatically return to the
LOCK position when any door is either opened or
closed with the switch in the OFF position.

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.
● Check that all doors are closed.
● Position seat and adjust head
restraints/headrests.
● 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 placed in the ON posi-
tion. See “Warning/indicator lights and au-
dible reminders” in the “Instruments and
controls” section of this manual.
BEFORE STARTING THE ENGINE
Starting and driving5-13

1. Apply the parking brake.
2. Move the shift lever to P (Park) or N (Neu-tral) . P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON position. Depress the brake pedal and push the igni-
tion switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After 5 or
6 seconds, stop cranking by pushing the
ignition switch to LOCK. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the accelerator pedal by depressing the
brake pedal and pushing the push-button
ignition switch to start the engine. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to the
OFF position and wait 10 seconds before
cranking again, otherwise the starter
could be damaged.
4. Warm-up
Allow the engine to idle for at least 30 sec-
onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the en-
gine running for a minimum of2-3minutes
before shutting it off. Starting and stopping
the engine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, shift the shift lever to the P (Park) position and push the ignition
switch to the OFF position. NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances. In these cases, the
battery may need to be charged to maintain
battery health.
REMOTE START (if so equipped)
Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift lever can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Press the ignition switch once to the ON position.
For additional information, see “NISSAN Intelli-
gent Key®” in the “Pre-driving checks and ad-
justments” section of this manual.

Shift lock release
If the battery charge is low or discharged, the
shift lever may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift lever button pushed. To move the
shift lever, perform the following procedure:1. Place the ignition switch in the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock release cover
Aus-
ing a suitable tool.
4. Push down the shift lock release
Busing a
suitable tool. 5. Press the shift lever button
Cand move the
shift lever to the N (Neutral) position
D
while holding down the shift lock release.
The vehicle may be moved to the desired
location. Replace the removed shift lock re-
lease cover after the operation. If the shift
lever cannot be moved out of the P (Park)
position, have a NISSAN dealer check the
CVT system as soon as possible.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Overdrive (O/D) OFF switch (if so
equipped)
When the O/D OFF switch is pushed with the
shift lever 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.
Each time the engine is started, or when the shift
lever 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.

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
harder to operate. Have the power
steering system checked by a NISSAN
dealer.
The power steering system is designed to pro-
vide power assist 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 electric power steering warning light
PS
illuminates while the engine is running, it may
indicate the power steering system is not func-
tioning properly and may need servicing. Have
the power steering system checked by a
NISSAN dealer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information see “Power steering
warning light” in the “Instruments and controls”
section. 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 driving5-27

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 can not prevent loss
of vehicle control in all driving situations.

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 NISSAN Intelligent Key®.
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “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 details, see “Battery” in the “Main-
tenance and do-it-yourself” section 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 details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide 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 four 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 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. 3. Tire chains may be used. For details, see “Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra washer fluid to refill the windshield-
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
● Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
COLD WEATHER DRIVING
Starting and driving5-33

3. Get out of the vehicle. Look and listen forsteam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant 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 State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures 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 service operator carefully read the following
precautions:
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.
