temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when the previous climate setting
was turned off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
the air flow outlet will return to previous
settings, and operation will continue
normally. To exit, press any climate con-
trol button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. ∙ If you feel that the air flow mode you
have selected and the outlets the air is
coming out do not match, select
the

∙ When you change the air flow mode, you may feel air flow from the foot out-
lets for just a moment. This is not a
malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioner 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.

SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, refer to ”Sys-
tem maintenance” in the “Lane Departure
Warning (LDW)” section.
WARNING
Failure to follow the warnings and in-
structions for proper use of the LDW
system could result in serious injury or
death.
∙ This system is only a warning deviceto inform the driver of a potential un-
intended lane departure. It will not
steer the vehicle or prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the ve-
hicle in the traveling lane, and be in
control of the vehicle at all times. The LDW system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The LDW system monitors the lane mark-
ers on the traveling lane using the camera
unit
Alocated above the inside mirror.
The LDW system warns the driver that the
vehicle is beginning to leave the driving
lane with an indicator and a steering wheel
vibration. For additional information, refer
to “LDW system operation” in this section.

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. This can also affect the
operation of the air bag system and re-
sult in serious personal injury.
CAUTION
∙ Never use benzine, thinner or anysimilar material.
∙ Small dirt particles can be abrasive and damaging to leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes, pol-
ishes, oils, cleaning fluids, solvents,
detergents or ammonia-based clean-
ers as they may damage the leather’s
natural finish.
∙ Never use fabric protectors unless recommended by the manufacturer.
∙ Do not use glass or plastic cleaner on meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following precau-
tions:
∙ Hanging-type air fresheners can cause permanent discoloration when they
contact vehicle interior surfaces. Place
the air freshener in a location that al-
lows it to hang free and not contact an
interior surface. ∙ Liquid-type air fresheners typically clip
on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufactur-
er’s instructions before using the air fresh-
eners.
POWER MOONROOF (if so
equipped)
The sunshade is made from a tricot mate-
rial.
CAUTION
To help prevent damaging the moon-
roof while cleaning:
∙ Do not rub the material with a cloth. Doing so can damage the surface of
the material or cause a stain to
spread.
∙ Never use benzine, thinner or any similar chemical to clean the sun-
shade. This may discolor the moon-
roof and damage the surface.
