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.
Monitor, climate, audio, phone and voice recognition systems4-33

The sunload sensor (if so equipped) , located on
the top passenger’s side of the instrument panel,
helps the system maintain a constant tempera-
ture. Do not put anything on or around this sen-
sor.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. For additional information, refer to “Air
conditioner system refrigerant and oil recommen-
dations” 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 con-
ditioning system.
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, any air conditioner service
should be done only by an experienced
technician with proper equipment.
RADIO
With the ignition placed in the ACC or ON posi-
tion, press the
(power ON) or ON-OFF
button to turn the radio on. If you listen to the
radio with the engine not running, the ignition
should be placed in the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the vehicle
may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However, there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area and do not indicate any malfunction
in your NISSAN radio system.

not start right away, place the ignition
switch in the OFF position and wait 3 to
4 seconds before trying again.
8. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Continuously Variable Transmission
(CVT) models and Manual Transmission
(M/T) cannot be push-started or tow-
started. Attempting to do so may cause
transmission damage
● For Manual Transmission (M/T) models,
never try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle. If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps.
WARNING
●
Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
● Do not open the hood if steam is com-
ing out.

CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery. Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator.

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* (for serviceable batteries): Check
the fluid level in each cell. It should be between
the MAX and MIN lines. 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 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.
