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.

WARNING
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep both doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close both the windows and
convertible top, lock the doors and the
fuel-filler lid and take the key with you
when leaving your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the fuel-filler lid,
always verify that they are securely closed:
Doors and the fuel-filler lid not securely
closed are dangerous, if the vehicle is
driven with a door and the fuel-filler lid not
securely closed, the d oor and the fuel-filler
lid could open unexpectedly resulting in an
accident.
Always confirm the safety around the
vehicle before opening a door and the
fuel-filler lid:
Suddenly opening a door and the fuel-filler
lid is dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
 Always
confirm the conditions around
the vehicle before opening/closing the
doors and the fuel-filler lid and use
caution during strong winds or when
parked on an incline. Not being aware of
the conditions around the vehicle is
dangerous because fingers could get
caught in the door and the fuel-filler lid
or a passing pedestrian could be hit,
resulting in an unexpected accident or
injury.
 If the power window does not go up or
down automatically because the battery
is dead, slowly open/close the power
window while pressing the glass inward.
Otherwise, the power window may
contact the convertible top/roof and the
door cannot be opened/closed resulting
in damage to the window.
