Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Do not place objects with sharp
edges on the seat. Also, do not place
heavy objects on the seat that will
leave permanent impressions in the
seat. Such objects can damage the
seat or occupant classification sen-
sor (weight sensor). This can affect
the operation of the air bag system
and result in serious personal injury. •
Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensor. This can also
affect the operation of the air bag
system and result in serious personal
injury.
• Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
• No unauthorized changes should be
made to any components or wiring
of the supplemental air bag system.
This is to prevent accidental inflation
of the supplemental air bag or dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.

•Tampering with the front air bag sys-
tem may result in serious personal
injury. Tampering includes changes
to the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad
and above the instrument panel or
by installing additional trim material
around the air bag system.
• Removing or modif ying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury.
• Modif ying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that is not specifically designed to
assure proper air bag operation. Ad-
ditionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (weight sensor). •
No unauthorized changes should be
made to any components or wiring
of the seat belt system. This may af-
fect the front air bag system. Tam-
pering with the seat belt system may
result in serious personal injury.
• It is recommended that you visit a
NISSAN certified LEAF dealer for work
on and around the front air bag sys-
tem. It is also recommended that you
visit a NISSAN certified LEAF dealer
for installation of electrical equip-
ment. The Supplemental Restraint
System (SRS) wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the air bag
system.
• A cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion. When selling your vehicle, we request that
