Start washing from the front of the vehicle. Make sure to re-install the
antenna and extend the mirrors before driving.
Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Rain-sensing windshield wipers (if equipped): Turn the wipers off before
washing the vehicle. (P. 219)
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity
of the windows.
Before car wash, check that the fuel filler door on your vehicle is closed
properly.
Perform the following to protect the vehicle and maintain it in prime
condition.
Working from top to bottom, liberally 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 thor-
oughly with water.

Maintenance and care
iQ_WE_74014E
Aluminum wheels (if equipped)
Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners. Use the same mild detergent and wax as used on the paint.
Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.
Bumpers and side moldings
Do not scrub with abrasive cleaners.
CAUTION
When cleaning the windshield (vehicles with rain-sensing windshield
wipers)
When the upper part of the windshield where the raindrop sensor is
located is touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
Caution about the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in AUTO, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.

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 you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust,
iron powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
If the paint is chipped 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 on the surfaces of the lights.
Wax may cause damage to the lenses.
Antenna installation and removal precautions
Before driving, ensure that the antenna is installed.
When the antenna is removed, such as before entering an automatic car
wash, make sure to store it in a suitable place so as not to lose it. Also,
before driving, make sure to reinstall the antenna in its original position.
To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side
wiper arm upward first, and repeat for the passenger side. When returning
the wipers to their original position, do so from the passenger side first.
