Notice

Boiling coolant and vapor may eject
under pressure, which may cause serious
injury. Do not open coolant expansion
tank lid when engine and water is hot.
Antifreeze in engine coolant may hurt
skin and eyes. Therefore necessary
measures must be taken for avoiding
antifreeze touch with eyes and skin. If
coolant touches skin or eyes, wash with
adequate water. If pain does not disappear,

see a doctor in time. Antifreeze content in
coolant is not over than 60% and not less
than 50%. Do not use alcohol or
methanol or mix them with specified
coolant. In coolant mixture, do use soften
water,do not mix over coolant. If needs
frequent adding, contact nearest CSSS.
Check cooling system. USE antifreeze
and coolant specified by Chery Sedan
Company.

Engine Overheating

If engine water temperature gauge
indicates high readings or other reasons is
doubted for causing engine overheating,
stop vehicle and check.
Turn off A/C, let engine idle for several
minutes. Check if cooling fan operates.
If cooling fan does not operate, turn off
ignition switch, and ask for help from
CSSS.
If cooling fan operates, but no hot vapor
occurs, open engine hood, let engine idle

till cooling down.
If cooling fan operates but temperature
keeps high, turn off engine and let engine
cool down, then check coolant level. If
coolant level falls, check if water tank
hose, connecting hose, water tank and
pump leak.
If any leakage is detected, do not run
engine. Contact and declare to the nearest
CSSS.

Notice

Vapor from overheated engine may hurt
skin. Keep anybody away from such high
temperature vapor. Turn off engine and
let engine cool down. After vapor
disappear, open engine hood.
SPECIAL NOTICE:
DO NOT open coolant expansion tank
before cooling system cooling down to
avoid person hurt.

Brake Fluid

Brake fluid has high desiccation character.
If over humidity is sopped up, hydraulic
brake system performance may be
affected. Therefore brake fluid must be
replaced as specified schedule in this
manual.
Fluid level in container should under
MAX and over MIN scale.
Low fluid level indicates brake system
leakage or consumption. It must be
checked and repaired at nearest CSSS in
time.

Service Schedule

Capacity

Replace brake fluid
every 30,000km or 18
months. Under bad
conditions, it should be
replaced every 15,000
km or 9 months.

0.45L

Clean before refilling brake fluid, then
open reservoir cap. And refill brake fluid
to MAX scale. Tighten brake fluid
reservoir cap.

Notice

Brake fluid may hurts skin and eyes. Do
not let brake fluid splash on skin or eyes.
If brake fluid touches skin or eyes, wash
with water thoroughly. If pain does not
disappear, see a doctor immediately. For
circumstance protecting purpose, store
removed fluid in specified container.
Brake fluid replacing must be completed
at CSSS. If braking system is fouled,

braking system will deteriorate. Clean
brake fluid reservoir surrounding area
before removing reservoir cap. Use
specified brake fluid authorized by Chery
company.
SPECIAL NOTICE: Brake fluid is
harmful to painting. If brake fluid
splashes on vehicle painting, clean with
water immediately.

Transmission Fluid

Transmission fluid level can only be
checked when engine is off, vehicle is
stopped on level surside and transmission
is cool enough to tough with hand.

Open  fluid  return  cap.  Check 

transmission fluid level. Fluid level 

should 

reach 

bottom 

of 

filler 

lid.

Service and Maintenance

If the level is too low, then fill till
overflow from filler. Tighten fluid filler
lid plug.

Use transmission fluid specified
lubrication table. After installing filler lid,
inspect if leakage or damage exists.

Notice

Fluid temperature is high after driving.
Wait till fluid and filler lid cool down.
For circumstance protecting purpose,
store used fluid or container in specified
unit.

Air Filter

If vehicle is driven under dusty condition,
clean or replace air filter frequently
(comparing with interval recommended).

Notice

If air filter is not replaced for a long time,
it will deteriorate engine performance and
engine component and further damager
engine.

Service Interval

Every 15,000 km half year: replace.
Every 5,000 km or 3 months: clean.

Spark Plug

Check spark plug as specified schedule.
If heavy carbon deposit exits on spark
plug, strong spark cannot generate which
will cause inadequate engine power.

Clean carbon deposit on spark plug. Use
brush to clean electrode, then raze carbon

on insulation with small fill. Then blow
using compressed air. Upper insulation

must be cleaned. Adjust spark plug
clearance (standard clearance is 0.7

mm-0.9 mm).
Service Interval

Every3,0000 kmor18 months,replace.

Replacing Spark Plug
-Clean dust on spark plug seat.
-Remove high tension wire, then remove
spark plug using spark plug wrench.
-Install new or cleaned spark plug using

hand force, rotate spark plug clockwise
for several turns. If spark plug cannot
be smoothly rotated, remove it and try
again. Ensure proper engage between
plug thread and cylinder head thread.

-Tighten spark plug to specified torque
using plug wrench (standard torque: 25 N.
m).
Connect high-tension wire using right
sequence.

Notice

If engine spark plugs are installed
improperly or plugs of wrong brand are
installed, stumble engine operating may
be caused, and even engine components

may be damaged. To prevent engine or
other components damaging, follow
below items:
1.  Spark plug must be tightened to

specified torque. Spark plug cannot
be over tightened, otherwise
cylinder body threads may be
damaged;

2.  Align plug with hole when removing

or tightening.

3.  When install spark plug, tighten

using hand force first.

4.  Pull the sleeve when install spark

wiring, do not pull spark plug.

5.  Do no use spark plug of other brand.
6.  Do not foul spark plug hole.
7.  Use cares to avoid accidental

burning when remove spark plug
while engine is at high temperature.

Drive Belt

Install belt properly and ensure
appropriate belt tension, otherwise
generator, A/C and other system
operating may be affected. If drive belt is
worn, cracked or swelled, replace it.
Check belt tension: apply appropriate
thumb pressure at the middle and
measure if belt displacement is about
10mm.If belt is too loose, adjust and
repair at nearest CSSS.

Notice

DO NOT run engine when checking belt,
otherwise moving parts will be pressed,

broken and twisted.
