Owner’s Instruction

Starting and Driving 3-7

Running-in procedures

●

BYD recommends that a car with
new transmission system (engine,
transmission,

differential

mechanism,

wheel

bearing,

transmission shaft) should not tow a
trailer within its initial 2000 km.

Maintenance

●

When the car tows a trailer, the car
has more load capacity. Therefore,
it

requires

more

frequent

maintenance.

How to Save Fuel and Lengthen
Service Life of the Car

It is easy and convenient to save fuel. It
also helps lengthen service life of the car.
Refer to the following tips to save fuel
fee and repair fee.

● Maintain proper tire pressure.

Insufficient tire pressure might cause
tire wearing and fuel wasting. (Refer
to description in chapter 7-2).

●

Do not place unnecessary load
on the vehicle. Overweight might
increase the engine load and
consume large quantity of fuel.

●

Avoid long-time warning up
idling. Once the engine operates
steadily, please drive steadily.
Preheating time in a cold day might
be longer.

●

Accelerate slowly and steadily.
Avoid fast starting. Please use high
speed gear while driving.

●

Avoid long-time engine idling. If
you have to wait for someone in a
area which is not busy, please turn
off the engine.

●

Avoid

lugging

down

or

over-speeding the engine. Please
select a proper speed gear in
accordance with road condition.

●

Avoid frequent acceleration and
deceleration. Frequent stop and
move wastes fuel.

●

Avoid unnecessary parking or

braking. Keep a steady speed.

Drive in accordance with traffic signal
lamps to reduce stopping times to the
minimum extent or drive on a highway
without traffic light. Keep a proper
distance from cars in the front of you to
avoid emergent braking. It will also
reduce brake wearing.


●

Avoid areas with busy traffic or
congestion as far as possible.

●

Do not place your foot on the
clutch pedal or the brake pedal.
Otherwise,

it

might

cause

premature wearing, overheating or
consumption of large quantity of
fuel.

●

Please maintain a proper speed
on a highway. The higher the
speed is, the more fuel the car
consumes. Slow the car speed to
save fuel.

●

Please maintain correct position
of the front wheel. Please avoid
bumping into road kerb. Drive

L3

Owner’s Instruction

Starting and Driving 3-8

slowly on bumpy road. If the front
wheel is not positioned accurately, it
will not only cause early wearing of
tire but also increase the engine
load. In another word, it will
increase oil consumption.

●

The chassis should be kept clean
and free of mud. It will not only
reduce car weight but also prevent
corrosion.

●

Adjust the car and keep it in the
optimistic

working

condition.

Dirty air filter, improper air valve gap,
dirty spark plug, dirty the engine oil
or lubricant, unadjusted brake might
affect the engine performance and
waste fuel. In order to maintain a
long service life of all parts and
reduce operation cost, please
provide regular maintenance. If the
car often travels in bad condition, it
requires

more

frequent

maintenance (refer to chapter 6).

FRIENDLY TIPS

When going down the slope, never
shut down the engine. If you turn off
the engine, power steering and

vacuum booster will not work.
Likewise, only when the engine is in
operation, exhaust pollution control
device can work normally.
