WARNING:
Riding with a reclined seatback
increases your chance of serious or
fatal injuries in the event of a collision or
sudden stop. The protection of your
restraint system (seat belts and airbags)
is greatly reduced by reclining your seat.
Seat belts must be snug against your
hips and chest to work properly. The
more the seatback is reclined, the greater
the chance that an occupant's hips will
slide under the lap belt or the occupant's
neck will strike the shoulder belt. Drivers
and passengers should always sit well
back in their seats, properly belted, and
with the seatbacks upright.
B100A01NF-AATSEAT WARMER (If Installed)The seat warmer is provided to warm the
front seats during cold weather. With the
ignition key in the "ON" position, push
either of the switches to warm the driver's
seat or the front passenger's seat.
During mild weather or under conditions
where the operation of the seat warmer is
not needed, keep the switches in the "OFF"
position.
o Each time you push the button, the
temperature setting of the seat is
changed as follows:
ONF038007
o The seat warmer defaults to the OFF
position whenever the ignition switch is
turned on.NOTE:o The seat warmer may not operate if
the ambient temperature is warm.
o If the seat warmer doesn't operate
when the ambient temperature is
lower than 75°F (24°C), it must be
checked at an authorized dealer.
OFF → HIGH (
) → LOW (
)

!
WARNING:
Do not turn on the seat warmers, if the
seat is occupied by someone who cannot
monitor the temperature and turn off the
seat warmer, if it becomes too warm.
The seat warmers should not be turned
on when children, the elderly, ill people,
and sleeping people occupy the seat.
