cautions on seat belt usage.
Supplemental air bag warning
light

bag or pre-tensioner seat belt systems need ser-
vicing and your vehicle must be taken to a
NISSAN dealer:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.cThe supplemental air bag warning light flashes
intermittently.
cThe supplemental air bag warning light does
not come on at all.

restraint system (air bag system) and/or the pre-
tensioner seat belts may not function properly.
For additional details see “Supplemental restraint
system” in the “Seats, restraints and supplemen-
tal air bag systems” section of this manual.

front air bag or supplemental side air bag
system (if so equipped) or pre-tensioner
seat belt system will not operate in an
accident.

Your vehicle has two types of security systems:
cNISSAN Vehicle Immobilizer System — NVIS
(if so equipped)
cVehicle security system (if so equipped)
NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS) (if so equipped)
The NISSAN Vehicle Immobilizer System (NVIS)
will not allow the engine to start without the use of
a registered NVIS key.
If the engine fails to start using a registered NVIS
key (for example, when interference is caused by
another NVIS key, an automated toll road deviceor automatic payment device on the key ring) ,
restart the engine using the following proce-
dures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position, and wait approximately 5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered NVIS key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered NVIS key on a
separate key ring to avoid interference from other
devices.
