8-1 When Failure Occurs 227
WARM TIP

It is not recommended to tow your vehicle by using a towing hook. You'd better contact
a professional towing service provider or the organization providing roadside rescue
service that you have joined.

Only the towing hook delivered with the vehicle can be used. Otherwise, your vehicle
will be damaged. Do not tow the vehicle at its tail with all four wheels on the ground;
otherwise, your vehicle will be damaged.
Shutdown of Motor during Driving

Be sure to gradually slow down the vehicle and keep the vehicle running in a straight
line. Carefully drive the vehicle off the road and to a safe place.

Turn on the hazard warning lights.

Restart the motor.
Vehicle Over-temperature

If the motor coolant thermometer indicates over temperature, the motor is subject to
degradation in power performance, or a very loud knocking sound or bang-bang sound
is heard, the motor may be overheated. In this case:

Safely drive the vehicle off the road, stop the vehicle, turn on the hazard waning
lights, press the "P" button and pull up the EPB switch. Make sure that the A/C
system is turned off.

If coolant or vapour is spraying out of the radiator or expansion tank, stop the
motor, wait until no more vapour emits and then open the front compartment hatch.
If there is no coolant or vapour spraying out, keep the motor running and check
whether the radiator fan is working. If not, turn off the START/STOP button.

Check if visible coolant leaks from the radiator, hoses and underneath the vehicle.
However, it is normal to find water drops coming from a working air conditioner.

If coolant leaks are found, immediately shut down the motor. In this case, contact a
BYD authorised service provider.

If no visible coolant leaks are found, check the expansion tank of coolant. If coolant
level is found to be below the MIN mark, fill coolant into the expansion tank with the
motor running, to the level between MIN and MAX marks.
