Maintenance of Painted Surface

Proper maintenance of the vehicle can prevent the vehicle from being corroded. The
most common causes of vehicle corrosion are as follows:

Saline and alkaline matters, dust and moisture are deposited at the positions hard
to be reached beneath the vehicle.

Paint or primer coats have been scratched by slight impact or stones and gravels.

Take care when driving in special areas and under special environment:

The dust of saline and alkaline matters or chemical substances on the road will
accelerate corrosion. Salt is also contained in the air in coastal regions or the
areas with industrial pollution.

High humidity will accelerate corrosion, especially in the circumstance where the
temperature is just above zero.

Some parts of the vehicle may be corroded because they are kept in a wet or
humid environment for a long time, even if other parts are kept dry.

Vehicle components which are not dried quickly due to the lack of correct
ventilation are liable to corrosion at a high ambient temperature.

The above-mentioned conditions indicate the significance of keeping clean of the
vehicle, especially the vehicle bottom, and of repairing the damaged paint coat and
protective coat as soon as possible.

The vehicle should be cleaned regularly to ensure the body is clean, thus preventing
the vehicle from rust. Wash your vehicle as follows to prevent corrosion:

If you have to drive the vehicle on saline and alkaline roads in winter, or if you live
by the sea, be sure to wash running parts of the vehicle at least once a month to
reduce corrosion.

High pressure or steam is very effective in washing the vehicle chassis and wheel
guards. However, direct washing the power battery below the chassis should be
avoided during washing. Pay special attention to the positions of these parts as it
is hard to see clearly the mud and dirt there. Simply wetting mud and debris
without removal will cause more serious hazards. Do not let dust block the lower
edges of doors, door sill plates and drain holes on all parts of the frame.
Otherwise, waterlogging at these positions will cause corrosion.

Wash the vehicle chassis thoroughly after winter.

Check paint and trims on the vehicle body.
If the paint coat is found with any chips or cracks, it should be repaired at once to
prevent corrosion starting from the positions of such chips or cracks.
If any chipping or cracking coat peels off from the metal surface, please contact a BYD
authorised service provider for repair.
