With this system, the front
passenger’s airbag is turned of f if
sensors detect a total weight of less
thanabout65lbs(30kg)intheseat.
(See page f or additional
inf ormation about how the f ront
passenger’s advanced airbag works.)
Even if the passenger’s f ront airbag
is turned of f , we strongly
recommend that children age 12 and
under ride properly restrained in a
back seat where they will be saf er.
Front airbags have been designed to
help protect adults in a moderate to
severe f rontal collision. To do this,
the passenger’s f ront airbag is quite
large, and it can inflate with enough
f orce to cause very serious injuries.
To help prevent airbag-caused
injuries to children, this vehicle has
an advanced airbag system.
According to accident statistics,
children of all ages and sizes are
saf er when they are restrained in a
back seat. The National Highway
Traffic Safety Administration and
Transport Canada recommend that
all children age 12 and under be
properly restrained in a back seat.
Children who ride in the second or
thirdrowarelesslikelytobeinjured
by striking interior vehicle parts
during a collision or hard braking.
Also, children cannot be injured by
an inf lating airbag when they ride in
the back. 25

Both f ront seats are equipped with
seat heaters. The ignition switch
must be in the ON (II) position to
usethem.Pushthefrontof the
switch, HI, to rapidly heat up the seat.
After the seat reaches a comfortable
temperature, select LO by pushing
the back of the switch. This will keep
the seat warm.In HI, the heater turns of f when the
seat gets warm, and turns back on
after the seat’s temperature drops.
In LO, the heater does not cycle with
temperature change.
Because of the sensors f or the side
airbag system, there is no heater in
the passenger’s seat-back.
Follow these precautions when using
the seat heaters:
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current f rom the
battery.
If the engine is lef t idling f or an
extended period, do not use the
seat heaters, even on the LO
setting. It can weaken the battery,
causing hard starting.
