ture setting or the inside temperature.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning system
is on
●In order to reduce the air conditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically. This may also reduce fuel consump-
tion.

IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Operation of the air conditioning system in Eco drive mode

●Working from top to bottom, liberally
apply water to the vehicle body, wheel
wells and underside of the vehicl e to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside temper-
ature.
The restoration time may become shorter when the coating is warmed by applying
warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■When using a car wash

door may lock and unlock repeatedly. In that case, follow the following correction proce-
dures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
