Lights - BYD BYD5030XYZBEV1 Manual


Avoid depressing the brake pedal during braking. Slowly depressing the brake
pedal can increase the energy of regenerative brake and extend the driving range.
It is proved by test that the energy of regenerative brake can extend the driving
range by 10%~15%.

The power consumption of air conditioner also takes a part in the energy
consumption of the service vehicle. Therefore, when the air conditioner is started,
windows should be closed and the air speed should be suitable to reduce power
consumption of the air conditioner and extend the driving range of the complete
vehicle.

Calibration of headlights
Before delivery of a new vehicle from the factory, the headlights have been calibrated. If
you often use the vehicle to carry heavy objects, the headlights may need to be re-
calibrated. It is recommended to have headlights calibrated by a BYD authorised service
provider.
Moisture in lights

After heavy rain or washing, the headlights, tail lights or turn signals in exterior
rearview mirrors may have moisture appearing inside. This phenomenon is similar to
condensation on inner side of windows in raining and does not indicate a fault in your
vehicle.

Each light is a relatively confined and narrow space and when it is lit, its temperature
will become very high (cover, mirror and others are liable to deform at a high
temperature); therefore, heat dissipation is needed for the lights. To meet the
requirements of heat dissipation of the lights when lit, heat dissipation holes are
provided in each light housing for heat dissipation via convection with the surroundings.
A higher temperature difference will cause more active convection. During convection,
water vapor in the air will inevitably enter the light. Affected by factors such as sun
exposure, convection and bulb heating, water vapor in the air is liable to condense into
mist or water drops when encountering light surface with a lower temperature, known
as vehicle light condensation.
WARNING

When the headlight bulbs illuminate, they will become very hot. Grease, sweat or
scratches on the surface of the bulbs will cause the headlights to overheat and break.
