484 7-1. Maintenance and care
NX300h_U_OM78007UCleaning and protecting the vehicle exterior ●
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 thoroughly with
water. ●
Wipe away any water. ●
Wax the vehicle when the waterproof 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 coating that is resistant to small surface scratches
caused in a car wash etc. ●
The coating lasts for 5 to 8 years after the coating has been performed. ●
The restoration time differs depending on the depth of the scratch and outside temper-
ature. The restoration time may become shor ter when the coating is warmed by apply-
ing warm water. ●
Deep scratches caused by keys or coins cannot be restored.●
Do not use wax that contain abrasives. ■
Automatic car washes ●
Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if equipped)
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. ●
Rear spoiler may not be washable in some automatic car washes. There may also be an
increased risk of damage to vehicle. ■
High pressure car washes ●
Do not allow the nozzles of the car wash to come within close proximity of the windows. ●
Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.Perform the following to protect the ve hicle and maintain it in prime condi-
tion:

Maintenance and care
NX300h_U_OM78007U NOTICE ■
To prevent paint deterioration and corrosio n on the body and components (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, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gaso line are spilled on the paint surface●
If the paint is chipped or scratche d, have it repaired immediately.●
To prevent the wheels from corroding, remo ve 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 su rfaces of the lights.●
Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses. ■
To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the dr iver 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. ■
When using an automatic car wash (vehicle s with rain-sensing windshield wipers)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers 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 fr om the high pressure water, it is possible
the device may not operate as normal. ●
Do not bring the nozzle tip close to followi ng parts and boots (Rubber or resin manu-
factured cover), or connectors. Parts may be damages if they come into contact with
high pressure water.

• Steering parts
• Suspension parts
