through indicators in your vehicle.
2-way communication is only available
if the garage door opener motor used
is a compatible device. (To check
device compatibility, refer to
www.homelink.com.)

Within 5 seconds after program-
ming the garage door opener has
been completed, if the garage door
opener motor is trained to Home-

indicators will flash rapidly (green)
and the light on the garage door
opener motor will blink twice, indi-
cating that 2-way communication is
enabled.

If the indicators do not flash, perform

and

“Smart” button on the garage door
opener motor. Within 5 seconds of
the establishment of 2-way com-
munication with the garage door
opener, both garage door opera-
tion indicators in the vehicle will
flash rapidly (green) and the light
on the garage door opener motor
will blink twice, indicating that

6-1.Maintenance and care

 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 opener and

closer

Start washing from the front of the vehicle.

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 win-

dows and the air suspension unit (if

equipped).

●

Before using the car wash, check that the

fuel filler door on your vehicle is closed

properly.

■

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 6 ft. (2 m) 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 access system

with push-button start. (

P.124)

■

Aluminum wheels

●

Remove any dirt immediately by using a

neutral detergent.

●

Wash detergent off with water immedi-

ately after use.

●

To protect the paint from damage, make

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-

tic, or containing wax on the uphol-

stery, as they may stick to the leather

surface if the vehicle interior heats up

significantly.

■

Water on the floor

Do not wash the vehicle floor with water.

Vehicle systems such as the audio system

may be damaged if water comes into

contact with electrical components such

as the audio system above or under the

Make sure to also remove dust and clogs

from the inner side of the air intake vent

grille.
If the filter is damaged, have it replaced by

your Lexus dealer.

Install the filter in its original posi-
tion, and then install the grille.

Start the hybrid system and check
that “Maintenance Required for
Traction Battery Cooling Parts See
Owner’s Manual” is no longer dis-
played on the multi-information dis-
play.

It may take approximately 20 minutes after

the hybrid system is started until the warn-

ing message disappears. If the warning

message does not disappear, have the

vehicle inspected by your Lexus dealer.

■

Scheduled maintenance of the air

intake vent is necessary when

In some situations such as when the vehicle

is used frequently or in heavy traffic or dusty

areas, the air intake vent may need to be

cleaned more regularly.
For details, refer to “Owner’s Manual Sup-

plement” or “Scheduled Maintenance”.

■

Cleaning the air intake vents

●

If the vehicle is driven with the air intake

vents and filters are clogged, the hybrid

battery (traction battery) may not be

cooled sufficiently, possibly causing an

increase in the fuel consumption and

damage to the hybrid battery (traction

battery).

●

Improper handling of the air intake vent

grilles and filters may result in damage to

them. If you have any concerns about

cleaning the filter, contact your Lexus

dealer.

■

If “Maintenance Required for Traction

Battery Cooling Parts See Owner’s

Manual” is displayed on the multi-infor-

mation display

●

It is possible the air intake vents or filters

are clogged due to accumulated dust.

Clean the air intake vents and filters,

referring to the cleaning method.

●

If the vehicle is driven continuously with

this message displayed, the hybrid bat-

tery (traction battery) may not be cooled

sufficiently, which may lead to the driving

distance by the electric motor becoming

shorter and damage to the hybrid battery

(traction battery). Clean the air intake

uum cleaner.

 Wipe off any excess dirt and dust

with a soft cloth dampened with

diluted detergent.

Use a diluted water solution of approxi-
mately 5% neutral wool detergent.
