Winter driving essentials
■
Ensure that the antifreeze can provide the correct freezing protection.
●
Use the same antifreeze as the original model, and select the appropriate
antifreeze model for the cooling system based on the ambient temperature.
●
Any use of an improper antifreeze will damage the motor cooling system.
■
Check battery and cable conditions.
●
The capacity of the battery will be reduced in cold weather; therefore, the battery
should be fully charged for winter start.
■
The door locks must not be frozen by ice and snow.
●
Spray some de-icing agent or glycerin in the keyhole of the door to prevent
freezing.
■
Use a washing solution containing antifreeze.
●
These products can be available at BYD Auto Authorized Service Stations and all
auto parts stores.
●
The mixing ratio of water and antifreeze should be in accordance with the
manufacturer instructions.
Note
●
Do not use other substitutes as washing solution, otherwise it may damage the
paints on the body.
