

Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle 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 water-
proof 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 coat-

ing 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 tem-

perature.

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 contains abrasives.

■

Automatic car washes

●

Before washing the vehicle:

• Fold the mirrors

• Turn off the power trunk lid
Start washing from the front of the vehicle.

Extend the mirrors before driving.

●

Brushes used in automatic car washes

may scratch the vehicle surface, parts

(wheel, etc.) and harm your vehicle’s

paint.

●

When it is necessary to set the engine

switch to ACCESSORY mode with the

shift position held in N, refer to P.178.

■

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.

■

When using a car wash

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

procedures to wash the vehicle:

●

Place the key in a position 2 m (6 ft.) or

more separate from the vehicle while the

vehicle 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.(

sure to observe the following precau-

tions.

• Do not use acidic, alkaline or abrasive

detergent

• Do not use hard brushes

• Do not use detergent on the wheels when

they are hot, such as after driving or park-

Where to go for maintenance service?

In order to maintain your vehicle in the best

possible condition, Lexus recommends that

maintenance service operations as well as

other inspections and repairs be carried out

by authorized Lexus retailers or Lexus

authorized repairers, or any reliable repair-

ers. For repairs and services covered by

your warranty, please visit an authorized

Lexus retailer or repairer, who will use gen-

uine Lexus parts in repairing any difficulties

you may encounter. There can also be

advantages in utilizing authorized Lexus

retailers or repairers for non-warranty

repairs and services, as members of the

Lexus network will be able to expertly assist

you with any difficulties you may encounter.
Your Lexus retailer or Lexus authorized

repairer, or any reliable repairer will per-

form all of the scheduled maintenance on

your vehicle reliably and economically due

to their experience with Lexus vehicles.

Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.

For full details of your maintenance sched-
ule, refer to the “Lexus Service Booklet” or
“Lexus Warranty Booklet”.

What about do-it-yourself mainte-
nance?

Many maintenance items are easy to do
yourself if you have a little mechanical abil-
ity and a few basic automotive tools.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you’re an experienced
do-it-yourself mechanic, we recommend
that repairs and maintenance be con-
ducted by any authorized Lexus retailer or
Lexus authorized repairer, or any reliable
repairer. Any authorized Lexus retailer or
repairer will keep a record of maintenance,
which could be useful should you ever
require Warranty Service. Should you
choose to select a qualified and equipped
professional other than an authorized
Lexus repairer to service or maintain your
vehicle, we recommend that you request
that a record of maintenance be kept.
