WARNING
■Seat adjustment
●Be careful that the seat does
not hit passengers or luggage.
●To reduce the risk of sliding
under the lap bel t during a colli-
sion, do not recline the seat
more than necessary. If the seat
is reclined too far, the lap belt
may slide past the hips and
apply restraint forces directly to
the abdomen, or your neck may
contact the shoulder belt,
increasing the risk of death or
serious injury in the event of an
accident.
Adjustments should not be made
while driving as the seat may
unexpectedly move and cause
the driver to lose control of the
vehicle.
■When adjusting the seat posi-
tion or the ottoman (vehicles
with Ottoman seats)
Make sure to leave enough space
around the feet so as not to get
them caught.
■When using the ottoman
(vehicles with Ottoman seats)
●Do not sit on the ottoman. Seat
belts may not be properly worn
which may result in death or
serious injury.
●Stow the ottoman when you get
in and out of the vehicle or when
the ottoman is n ot in use to
avoid stumbling over it.
●Do not use the ottoman feature
when the vehicle is in motion.
The ottoman feature should
only be used when the vehicle
is stationary. If the ottoman fea-
ture is in use during an accident
the lap belt may slide past the
hips. This could also result in
restraint forces being applied to
the abdomen or your neck may
contact the shoulder belt,
increasing the risk of death or
serious injury.
