While the vehicle is moving, always keep the head, hands
and other parts of the body of all occupants away from the

Unattended children can become involved in serious
accidents.
Never sit on top of the vehicle around the roof opening.

BODY
271 Check the interior of your vehicle. Water and dirt can accumulate
under the floor mats and could cause corrosion. Occasionally check
under the mats to make sure the area is dry. Be particularly careful
when transporting chemicals, cleansers, fertilizers, salt, etc. These
should be transported in proper containers. If a spill or leak should
occur, immediately clean and dry the area.
Keep your vehicle in a well ventilated garage or a roofed place.
Do not park your vehicle in a damp, poorly ventilated garage.
If you wash your vehicle in the garage, or if you drive it in covered
with water or snow, your garage may be so damp it will cause
corrosion. Even if your garage is heated, a wet vehicle can corrode
if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus
Keep your vehicle clean by regular washing.
The following cases may cause weakness to the paint or corrosion
to the body and parts. Wash your vehicle as soon as possible.
When driving in a coastal area
When driving on a road sprinkled with antifreeze
When having stuck of coal tar, tree sap, bird droppings and
carcass of an insect.
When driving in the areas where there are a lot of smoke, soot,
dust, iron dust and chemical substance
When the vehicle becomes remarkably dirty with dust and mud
Handwashing your Lexus
Work in the shade and wait until the vehicle body is not hot to the
touch.
1. Rinse off loose dirt with a hose. Remove any mud or road salt
from the underside of the vehicle or in the wheel wells.
2. Wash with a mild carwash soap, mixed according to the
manufacturer ’s instructions. Use a soft cotton mitt and keep it wet
by dipping it frequently into the wash water. Do not rub hard let
the soap and water remove the dirt.
