cap is loose or missing, or if the vehicle runs out
of fuel. Check to make sure the fuel-filler cap is
installed and closed tightly, and that the vehicle
has at least 3 gallons (11.4 liters) of fuel in the
fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 sec-
onds and then blinks for 10 seconds when the
engine is not running, it indicates that the vehicle
is not ready for an emission control system
inspection/maintenance test. For additional infor-
mation, refer to “Readiness for
inspection/maintenance (I/M) test” in the “Tech-
nical and consumer information” section of this
manual.

Operation
The MIL will come on in one of two ways:● MIL on steady — An emission control system
malfunction has been detected. Check the
fuel-filler cap if the LOOSE FUEL CAP
warning appears in the vehicle information
display. If the fuel-filler cap is loose or miss-
ing, 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 inspected by a NISSAN
dealer. You do not need to have your vehicle
towed to the dealer.
● MIL blinking — An engine misfire has been
detected which may damage the emission
control system. To reduce or avoid emission
control system damage:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on steady.
Have the vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.

WARNING
Do not use or allow occupants to use the
seat heater if you or the occupants cannot
monitor elevated seat temperatures or
have an inability to feel pain in body parts
that contact the seat. Use of the seat
heater by such people could result in seri-
ous injury.
CAUTION
●The battery could run down if the seat
heater is operated while the engine is
not running.
● Do not use the seat heater for extended
periods or when no one is using the
seat.
● Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion or seat cover, etc. Otherwise, the
seat may become overheated.
● Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
● Any liquid spilled on the heated seat
should be removed immediately with a
dry cloth. ●
When cleaning the seat, never use
gasoline, benzine, thinner, or any simi-
lar materials.
● If any malfunctions are found or the
heated seat does not operate, turn the
switch off and have the system checked
by a NISSAN dealer.
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most driv-
ing conditions.
If the vehicle is stuck in mud or snow, the VDC
system reduces the engine output to reduce
wheel spin. The engine speed will be reduced
even if the accelerator is depressed to the floor. If
maximum engine power is needed to free a stuck
vehicle, turn the VDC system off.
To turn off the VDC system, push the VDC OFF
switch. The
indicator will come on.
