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.
Rear spoiler (if equipped) may not be washable in some automatic car washes. There
●
may also be an increased risk of damage to vehicle.
High-pressure car washes
■
As water may enter the cabin, do not bring the nozzle tip near the gaps around the
●
doors or perimeter of the windows, or spray these areas continuously.
Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
●
erly.
Notes for a smart entry & start system
■
If the door handle becomes wet while the electronic key is within the effective range, the
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 2 m (6 ft.) or more separate from the vehicle while the vehi-
●
cle is being washed. (Take care to ensure that the key is not stolen.)
Set the electronic key to battery-saving mode to disable the smart entry & start system.
