CAUTION
■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle.
•Even when the system is in use, the internal temperature may still
reach a high level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke or dehydra-
tion, or could result in death or serious injury.
•The wipers can be operated during system operation. Children or pets
left inside the vehicle may mistakenly operate these and cause an acci-
dent.
●Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
●Turn the wipers off. If the Remote Air Conditioning System operates while
the wiper switch is in the on position, the wipers may operate and objects
may get caught in the wiper blades.

operate unintentionally and objects may be drawn into the electrical cool-
ing fan.

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (→P. 4 6 9 )

Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
