●Please make sure that there is no
snow, leaves or other barriers in the
inlet grille, to guarantee a normal
ventilation system of the vehicle.
●In case of an exhaust gas smell in
the vehicle, please immediately
check the cause and correct it.
Oil function
The oil mainly works for lubricating
and cooling the inside of the engine
to keep a normal working state.
Oil consumption
The engine will consume some oil
during a normal operation. In a
normal case, the engine consumes
oil due to the following causes:
●Lubricating the piston, piston ring
and cylinder: When the piston moves
down in the cylinder, it will leave a layer
of oil film. When the vehicle decelerates,
the high negative pressure will absorb
such oil into the combustion chamber.
Like part of oil film left on the cylinder
wall, this oil will be combusted by the
high-temperature combustion gas.
Keeping the oil level at the best level
is one of the key points for the normal
maintenance for a vehicle, which will not
weaken the function of the oil Therefore
it is very important to check the oil level
regularly You are recommended to
check the oil level every time you fill
oil

Brake System
It is a two-circuit brake system. In case
that one brake system loses effect, the
other one will still work. Meanwhile, it is
harder than usual to step down the
brake pedal and the brake distance
will also increase.
●Lubricating the intake valve stem:
The oil and the inlet air will be together
absorbed into the combustion chamber
and combust with the fuel. The
high-temperature waste gas will also
combust the oil used for lubricating
the exhaust valve stem.
The consumption of oil is related with
its viscosity, quality and the vehicle
use state.
The oil consumption will increase with
a high-speed driving, frequent
acceleration or deceleration.
More oil will be consumed due to the
piston, piston ring and cylinder wall
of a new engine, all of which have not
been run in.
Importance for checking the oil level
If a regular check at the oil level can
not be achieved a severe trouble
will be caused to the engine due
to a relatively low oil level.
,
Please refer to “Check the Oil Level”
in Section 7- 2 for detail.
Warning
Note
Do not drive the vehicle for a long
distance in case of only a brake
circuit working. Please immediately
repair the ineffective brake system.
Vacuum booster
It is used to assist the braking by the
inlet negative pressure of engine. In
case the engine stops during driving,
a pedal force bigger than usual is
required to stop the vehicle.
Note
●In case of a misfire of the engine, do
not step on the brake pedal repeatedly,
because every stepping will consume
of vacuum pressure.parts
●The brake will still be effective even
if the vacuum power is entirely lost.
However, the force to step on the
brake pedal will be much bigger than
usual and the brake distance will
also increase.
