4. The indicator light for the pushed memory switch will come on and stay
on for approximately 5 seconds.
5. The chime will sound if the memory has been stored.
NOTE:
If a new memory position is stored in the
same memory switch, the previous
memory position will be overwritten by
the new stored position.
Confirming memory storage
Push the SET switch. ∙ If a memory position has not been stored in the switch (1 or 2) the indicator
light for the respective switch will come
on for approximately 0.5 seconds. ∙ If a memory position has been stored in

Linking an Intelligent Key to the
meter display (if so equipped)
Each Intelligent Key, up to a maximum of
four, can be linked to the meter display.
1. When the system is enabled, the recog- nized Intelligent Key is displayed at start
up, as well as within “Key-Linked Set-
tings”.
2. When the system is active, the meter setting items are memorized for each
Intelligent Key that has been enabled in
the system.
3. The auto drive positioner system is memorized automatically when the ig-
nition switch is turned from ON to OFF
by the Intelligent Key with no need to
set separate buttons for recalling and
memorizing positions.
4. If two Intelligent Keys are in the vehicle, the system will recognize the Intelli-
gent Key that was used most recently,
such as to unlock/lock the door. 5. If there is a desire to change to another
Intelligent Key while in the vehicle, the
user must place the ignition switch in
the OFF position and initiate communi-
cation from the desired Intelligent Key.
a. Ignition from ON position to the OFF
b. Unlock door with the desired Intelli- gent Key
c. The desired Intelligent Key number should appear on the meter display.
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automati-
cally move when the shif t lever is in the P
(Park) position. This allows the driver to
easily get in and out of the driver’s seat.
The driver’s seat will slide backward and
the steering wheel will move up:
∙ When the driver’s door is openedand the ignition switch is in the
OFF position.
∙ When the ignition switch is turned from ACC to OFF with the driver’s door open.
3-32Pre-driving checks and adjustments

Vehicle set-up1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shif t lever in the P (Park) position.
3. Place the ignition switch in the ON po- sition. Do not start the engine.
Operation 1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. ∙ If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators
flash three times. To correct the pres-
sure, push the core of the valve stem
on the tire briefly to release pressure.
When the pressure reaches the des-
ignated pressure, the horn beeps
once.
∙ If the hazard indicator does not flash within approximately 15 seconds af-
ter starting to inflate the tire, it indi- cates that the Easy-Fill Tire Alert is
not operating.
∙ The TPMS will not activate the Easy- Fill Tire Alert under the following con-
ditions:
– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
∙ If the Easy-Fill Tire Alert does not op- erate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.
As with any vehicle, loss of control could
result in a collision with other vehicles or
objects or cause the vehicle to roll over,
particularly if the loss of control causes
the vehicle to slide sideways.
Be attentive at all times, and avoid driving
when tired. Never drive when under the in-
fluence of alcohol or drugs (including pre-
scription or over-the-counter drugs which
may cause drowsiness). Always wear your
seat belt as outlined in the “Safety – Seats,
seat belts and supplemental restraint sys-
tem” section of this manual, and also in-
struct your passengers to do so.
5-8Starting and driving

CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
∙ Do not use a cleaner that uses strongacid or alkali contents to clean the
wheels.
∙ Do not apply wheel cleaners to the wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
∙ Rinse the wheel to completely remove the cleaner within 15 minutes af ter
the cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint. If you choose to use a tire dressing, take the
following precautions:
∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is
completely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifi-
cation sensor (if so equipped). This can
also affect the operation of the air bag
system and result in serious personal
injury.
CLEANING INTERIOR
7-4Appearance and care

When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:1. With the ignition in the OFF position, the shif t lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t
lever in the P (Park) position and with
the parking brake applied, fully apply
and release all pedals. The floor mat
must not interfere with pedal opera-
tion or prevent the pedal from return-
ing to its normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.
WARNING
Do not allow wet seat belts to roll up in
the retractor. NEVER use bleach, dye or
chemical solvents to clean the seat
belts, since these materials may se-
verely weaken the seat belt webbing.

belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
The fluid should be at the bottom of the
filler opening. Vehicles operated in high
temperatures or under severe conditions
require frequent checks of the battery fluid
level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, 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. Brake fluid level*:
Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level spot and
turning off the engine. Wait more than
15 minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
