WARNING
Be careful when using the seat warmer:
The heat from the seat warmer may be too
hot for some people, as indicated as
follows, and could cause a
low-temperature burn.
 Infants, small children, elderly people,
and physically challenged people
 People with delicate skin
 People who are excessively fatigued
 People who are intoxicated
 People who have taken sleep-inducing
medicine such as sleeping pills or cold
medicine
Do not use the seat warmer with anything
having high moisture-retention ability such
as a blanket or cushion on the seat:
The seat may be heated excessively and
cause a low-temperature burn.
Do not use the seat warmer even when
taking a short nap in the vehicle:
The seat may be heated excessively and
cause a low-temperature burn.
Do not place heavy objects with sharp
projections on the seat, or insert needles or
pins into it:
This could cause the seat to become
excessively heated and result in injury from
a minor burn.
CAUTION
Do not use organic solvents to clean the
seat. It may damage the seat surface and
the heater.
NOTE
Use the seat warmer when the engine is
running. Leaving the seat warmer on for
long periods with the engine not running
could cause the battery power to be
depleted.
If the ignition is switched off while the
seat warmer is operating (High, Mid or
Low) and then switched ON again, the
seat warmer will automatically operate
at the temperature set before switching
off the ignition.
The temperature of the seat warmer
cannot be adjusted beyond High, Mid
and Low because the seat warmer is
controlled by a thermostat.

▼Curtain Air Bags
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag inflates quickly and helps to
reduce injury mainly to the rear outboard
passenger's head caused by directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-63).
In a side impact:
Greater than moderate impact to one side of the vehicle will cause the curtain air bag on that
side only to inflate.

Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.
(With Front Passenger Occupant Classification System)
In a roll-over:
In response to a vehicle roll-over, both curtain air bags inflate.

Both curtain air bags will deploy after
the roll-over accident is detected.

A system malfunction or operation conditions are indicated by a warning.
