 Do not attach anything to areas such as
the door, windshield glass, side door
glass, front, center and rear pillars, roof
side rail or assist grip. (Vehicles with
emergency tire puncture repair kit:
Except for the speed limit label P. 694)
 Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and
seriously injure or kill you, should the
SRS curtain shield airbag deploy.
 Vehicles without smart entry & start
system: Do not attach any heavy, sharp
or hard objects such as keys or acces-
sories to the key. The objects may
restrict the SRS knee airbag inflation or
be thrust into the driver's seat area by
the force of the deploying airbag, thus
causing a danger.
