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
●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, 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 your NISSAN dealer.
● The battery could run down if the seat
heater is operated while the engine is
not running.
The vehicle should be driven with the VDC sys-
tem on for most driving 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.
Push the VDC OFF switch again or restart the
engine to turn on the system. For additional infor-
mation, refer to “Vehicle Dynamic Control (VDC)
