OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.
The sunload sensor, located on the top of the
instrument panel on the driver’s side, helps the
system maintain a constant temperature. Do not
put anything on or around this sensor. The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. See “Air conditioner system refrigerant
and oil recommendations” in the “Technical and
consumer information” section of this manual.
A NISSAN dealer is able to service your “environ-
mentally friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
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 pressure
sensors.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
TPMS will not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate. Some examples are:
– Facilities or electric devices using similar radio
frequencies are near the vehicle.
– If a transmitter set to similar frequencies is being used in or near the vehicle.
– If a computer (or similar equipment) or a DC/AC converter is being used in or near the
vehicle.

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 ma-
neuvers, 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
Starting and driving5-5

To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces. Remember that stop-
ping distances on slippery surfaces will be
longer than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways maintain a safe distance from the
vehicle in front of you. Ultimately, the
driver is responsible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
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.
Starting and driving5-25

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. When the VDC system operates, the
indi-
cator in the instrument panel flashes so note the
following:
● The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
See “Slip indicator light” and ”Vehicle Dynamic
Control (VDC) off indicator light” in the ”Instru-
ments and controls” section.
If a malfunction occurs in the system, the
andindicator lights come on in the instru-
ment panel. The VDC system automatically turns
off when these indicator lights are on.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.

CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Shift the manual transmission into R
(Reverse) , or the CVT into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the manual transmission is
shifted into R (Reverse) , or the CVT is
shifted into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
Blocking wheels
Place suitable blocks1at both the front and
back of the wheel diagonally opposite the flat tire
2to prevent the vehicle from moving when it is
jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
WCE0044
In case of emergency6-3

●Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as am-
bient temperature.
● Rinse the wheel to completely remove
the cleaner within 15 minutes after 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 discoloration of the rub-
ber. If a tire dressing is applied to the tires, it may
react with the coating 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 coat-
ing 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 difficult to
remove) .
● Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/grooves.
● Allow the tire dressing to dry as recom-
mended by the tire dressing manufacturer. Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather surfaces with a clean, soft cloth damp-
ened in mild soap solution, then wipe clean with a
dry, soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather.
Before using any fabric protector, read the manu-
facturer’s recommendations. Some fabric pro-
tectors 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 classifica-
tion sensor. This can also affect the opera-
tion of the air bag system and result in
serious personal injury.
