Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface, which
can harm your vehicle’s paint.
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows or door weather seals of your vehicle.
Before entering the automatic car wash, check that the fuel filler door on your vehi -
cle is closed properly.
Follow these guidelines when washing and waxing your Lexus:
●Working from top to bottom, libera lly apply water to the vehicle body,
wheel wells and underside of the vehi cle to remove any built up dirt
and dust. 
Wash the vehicle body using a sponge or sof
t cloth, such as a chamois.
●For hard-to-remove dirts, use car wash soap and rinse thoroughly with
water.
●Thoroughly dry your vehicle.
●Apply polish or wax only when the vehicle body is cool. 
Wax or polish your vehicle when the e
xisting coating of wax or polish
begin to deteriorate. A good way to determine this, is by checking to
see if water beads on the painted surfac e of your vehicle. If it does not
bead, that means the wax or polish is no longer protecting the finish,
and therefore should be reapplied.
