maximum rated weight of the
towing hook; otherwise,
accidents and severe human
damage may be caused.
Towing may increase the brake
distance, so in trailer towing,
the safety distance should be
lengthened. At a speed of
10km/h (kilometer/hour), the
distance between your vehicle
and the preceding vehicle
should be at least the sum of
the lengths of your vehicle and
the trailer. Avoid emergency
braking; otherwise slipping
may cause vehicle folding and
make the vehicle out of control.
Tires
Make sure the tires have

proper pressure.
Keep the trailer tire pressure

at the pressure strength
defined by the trailer
manufacturer according to the
total weight of the trailer.

Running-in procedures
BYD Company suggests that all

new vehicles or vehicles with new
parts (engine, speed reducer,
differential, wheel bearing,
transmission shaft, etc.) not haul
trailers in the first 2,000km
(kilometer).
Maintenance
Trailer towing will increase the

load of the vehicle, so it should be
maintained more frequently.
How to save fuel and prolong the
vehicle service life
Fuel consumption can be reduced
easily and conveniently. It can also
lengthen the service life of the vehicle.
Following is some knowledge on
reducing the fuel and repair
expenditure:
Keep proper tire pressure. Tire

pressure insufficiency will lead to
tire wear and increase the fuel
consumption.
Do not place unnecessary

things on the vehicle. Too heavy
weight will increase the engine
load and lead to fuel consumption
increase.
Avoid long-time warming up

idling. Once the engine has
entered steady state, you can
start driving, but the operation
should be steady. It should be
noted that in cold weather, the
longer time is needed to warm up
the engine.
Accelerate slowly and steadily.

Avoid sudden start. Drive at
high-speed gear as soon as
possible.
Avoid long-time engine idling.

To wait for others when the traffic
is not busy, you'd better stop the
engine and, after the people have
come, start it again.
Avoid lug down or over-speed

operation of the engine. Select
proper speed gear shifts
according to the road conditions.
