Maintenance and care ■
Brake caliper coating (F SPORT mod-
els)●
When using detergent, use neutral deter-
gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the
coating.●
Do not use detergent on the brake cali-
pers when they are hot.●
Wash detergent off immediately after
use.■
Bumpers and side moldings
Do not scrub with abrasive cleaners. ■
Front side windows water-repellent
coating (if equipped)●
The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side
windows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp
cloth as soon as possible.
• Do not use wax or glass cleaners that
contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to
remove condensation build up.●
When the water-repellent performance
has become insufficie nt, the coating can
be repaired. Contact your Lexus dealer.■
Plated portions
If dirt cannot be removed, clean the parts as
follows: ●
Use a soft cloth dampened with an
approximately 5% solution of neutral
detergent and water to clean the dirt off.
●
Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●
To remove oily deposits, use alcohol wet
wipes or a similar product. WARNING■
When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire. ■
When cleaning the windshield
Set the wiper switch to off.
