■Before programming HomeLink®
During programming, it is possible
that garage doors, gates, or other
devices may operate. For this rea-
son, make sure that people and
objects are clear of the garage door
or other devices to prevent injury or
other potential harm.
 It is recommended that a new bat-
tery be placed in the remote control
transmitter for more accurate pro-
gramming.
 Garage door opener motors manu-
factured after 1995 may be
equipped with rolling code protec-
tion. If this is the case, you may need
a stepladder or other sturdy, safe
device to reach the “Learn” or
“Smart” button on the garage door
opener motor.

Steps 1 through 3 must be performed
within 60 seconds, otherwise the indi-
cator light will stop flashing and pro-
gramming will not be able to be

NOTICE
■To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels, etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, in sect droppings or
bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chip ped or scratched,
have it repaired immediately.
●To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
●Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged.
■When using a high pressure car wash
●When washing the vehicle, do not let
water of the high pressure washer hit
directly or the vicinity of the camera.
Due to the shock from the high pres-
sure water, it is possible the device may
not operate as normal.
●Do not bring the nozzle tip close to
boots (rubber or resin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged.
Also, do not continuously hold the nozzle
in the same place.
●Do not spray the lower part of the
windshield continuously.
If water enters the air conditioning sys-
tem intake located near the lower part of
the windshield, the air conditioning sys-
tem may not operate correctly.
●Do not wash the underside of the vehi-

3606-1. Maintenance and care
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle, such as on the floor, in the hybrid
battery (traction battery) air vents, and
in the luggage compartment.
Doing so may cause the hybrid battery,
electrical components, etc. to mal-
function or catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet.
( P.30)
An electrical malfunction may cause
the airbags to deploy or not function
properly, resulting in death or serious
injury.
●Vehicles with wireless charger: Do not
let the wireless charger ( P.335) get
wet. Failure to do so may cause the
charger to become hot and cause
burns or could cause electric shock
resulting in death or serious injury.
■Cleaning the interior (especially
instrument panel)
Do not use polish wax or polish cleaner.
The instrument panel may reflect off the
windshield, obstructing the driver’s view
and leading to an accident, resulting in
death or serious injury.
NOTICE

sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.

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
floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.214)
■Cleaning the inside of the rear win-
dow
