Service Precautions

Take care when check or repair vehicle to
prevent person injury or damage.
Read and comply following general
precautions when service vehicle:

Turn off engine and let engine cool down
when engine is hot.
Use car stand when work under vehicle.
Do work under vehicle when a jack
supports vehicle.
Fireworks, flame and electricity spark
should be far away from battery, all parts
related with fluid to avoid sudden

accident.
Do not reverse battery poles when
connecting.
Take care to avoid short on vehicle
battery, ignition wiring or high load
current or voltage.
Keep good ventilation when work in
closed condition as auto repairing
workshop (especially when engine is
running).
Avoid children touching used oil, coolant
and other fluid.
Use specified disposal unit when dispose
used oil, fluid and container.
Stop vehicle on level surface, shift
selector to neutral position and apply

manual brake when work under engine
hood while engine is running, otherwise
an sudden accident may be caused.
To avoid accident, turn off engine and
remove ignition key before working
under engine hood, unless engine ON is
required. If work under engine hood must
be performed while engine is running,
keep any possible matter (such as cope
and fabric) away from engine or cooling

Service and Maintenance

Engine oil checking procedures
Ensure engine oil at specified level and
right lubrication. Inspect oil level because
oil will consume when engine runs.
Vehicle must be stopp ed at level surface
when checking. Wait several minut es
when checking oil level ensuring oil
return oil pan. If engine is cold, it will
take a long time for oil returning.
Checking Oil Level: remove oil dipstick
and clean with discottony cloth, then
insert dipstick to full. Remove dipstick
and inspect if oil is between M IN and
MAX scale.

Check if dipstick is dirty.
If oil level is under M IN scale, add oil to
ensure oil level reaches M AX scale. Oil
should not surpass MAX scale, otherwise
oil consumption will increase which will
foul spark park and cause carbon deposit.

When add oil, use same brand and grade
oil with previous.

！Notice
Avoid frequent touch with engine oil;
otherwise skin illness will be caused.
Clean thoroughly after touching oil. Used
oil should be kept away from children.
Inadequate and over oil will cause engine
damage. Inspect engine oil timely and
frequently. Add oil as necessary. DO
NOT over add engine oil.

SPECIAL CAUTION:

For engine damage caused by inadequate
oil, manufacturer does not effect
warranty.
Replacing engine oil and oil filter
Replace engine oil up on t ime and m ileage
interval because oil may also deteriorate
with time besides engine running.
Under special conditions as frequent cold
starting and on-off switching in
municipal road surface, engine oil and oil
filter replacing interval shall shorten
accordingly (comparing with
recommended service schedu le)
Replace oil filter when replace oil.

dispose used oil as normal waste. Dispose
should be accordant to Chery Sedan
Special Service Station (CSSS) or local
safety disposal unit.

Coolant Level

Cooling system shall be filled with glycol
coolant. Under normal concentration,
coolant supplies good antisepsis and
antifreeze protection, therefore common
water cannot be used to replace cool ant
even in summer season.

When engine is cold, coolant shall be
within M AX and M IN scale on expansion
tank. Level rises with engine temperature
increasing and falls with engine coo ling.
If coolant level is under M IN scale, add
anti-freezing mixture of 50% water and

Wheel and tire

The tires fitted by the manufacturer
match the chassis and achieve op timum
running comfort and security.Before
exchanging other diverse type tires or
wheels, consult the server guested by
Chery Automobile to obtain technical
support. The using of improper tires or
wheel may cause an accident.

！Notice
The wrong tire size will gave rise to
contradiction between tires and body .If
you replace 145 / 65 RB tires with 155 /
65 RB ones; you need to alter steering
device components. Whenever replace
original type tires with other type ones,
you should consult chery automobile
guest service station.

Tire inflation

M easure tire pressure with the precise tire
gauge under low temperature..The

specified tire pressure is necessary for
driving comfort, traveling security and
tire life lengthening. Check the pressure
of tires (including wheel spare wheel)
every other 14 days or before
long-distance travel.

The air pressure may drop below the
specified minimum value and the
pressure will not descend when tires heat.
After air pressure examination, tighten up
the valve cap.

If the tire pressure do not comply with the
provisions, tire abrasion will be
accelerated and inf luence secur ity,
automobile operability, comfort and fuel

oil fuel oil efficiency. Too low air
pressure will give rise to tire radiation
and internal loss and result in tire crack
and tire flat during high-speed driving.
Undiscovered damage on the tire cannot
be eliminated by inflation pressure
adjustment.
Tire conditionThe tire shall not press on
the uneven side at parking. Driving on
sharp edge could bring about tire hidden
defect, which probably bring about the
danger of deflation. Drive on the rough
road with the appropriate angle slowly if
possible. Termly search tire damage
which can give rise to tire burst, such as
foreign impuritie, deflation, laceration,
fissures and crossrange salient. And
search hud damage. If there occurs
damage or inordinate wear, seek help
from Chery automobile guest service
station

Service and Maintenance

116

Inordinate wear is usually caused by the
following causes including tire pressure
in nonconformity with the provisions, no
periodic tire alternation, incorrect wheel
alignment, tire unbalance, emergent
braking or bad driving habit.

Tread wear indicator

Termly inspect tread pattern depth in
order to assist you in judging when to
replace the tire. There is bu ilt-in tire tread
wear indicator on the tire. When the tire
tread is 1.6 mm thick or less thicker, the
indicator will occur between the tread
patterns, and the position of the wear
indicator is displayed by longitudinal
indicator on the tire. Due to security
consideration, replace the tire if its tread
abrasion depth is 2~3 mm. Replace tires
in coup le, Select the correct fixing
sequence. Guarantee identical tire sizes,
identical type and identical technology of
the two tires on the same axle shaft and
the identical tread p atterns.

！Notice
Tire mixed using or inferior brand using
can make vehicle out of control and the
using of various sizes will harm
automobiles. Guarantee the same sizes
and type of the entire wheel. Use
specified tire by original factory. It is
extremely risky to use wear tire, junk tire
or damaged tire, even going to the length
of an accident If the following
circumstances occur, including tire tread

abrasion indicator exposure or tire
damage, please replace the tire. The used
tire is harmful to health and environments
and should not be disposed as house
garbage. It should be cleaned up with
locally specified security cleaning
mechanism

The wicked road

environments such as water , snow , ice
and grit will reduce towing force ,make
vehicle out of control, so under such
circumstances, driving should be slow.
Tire alternation
The service conditions of front and rear
wheel are different, so the abrasion status
is different too. It depends mainly on
running road surface, driving habit and so
on. For the front wheels abrase more
rapidly than the back wheels, in order to
avoid tire wear irregularity and lengthen
tire life , replace the tires ,adjust tire air
pressure and inspect wheel nut tightness
every other 5000 Km is necessary

Col

d enduring tire
If using cold enduring tire, 4 tires must be
assembled at the same time.Driving speed

should not exceed the specified highest
speed of a vehicle by tire manufacturer.
Using cold enduring tire must conform to
tire pressure specified by the tire

manufacturer.

！ NoticeUsing cold enduring tire can
cause adverse impact on the security and

Service and Maintenance

117

automotive dirigibility .Use standard tires
with the same sizes and the same type.
Don't use cold enduring tire so long as
road conditions permit.
Snow chain
According to the road location or mode,
alter tire chain regulation and inspect the
chain before installation. When install
chain on the tires, please necessarily
carefully observe the provisions by the
chain manufacturer.

Before chain

installation, please take away wheel
housing in case that the chain scratches
the wheel housing. Firmly fix the chain
on the front tires. It is advisable that it not
be used on the rear wheel. After running
of 0.5~1.0km,fasten the chain once again.

！NoticeUsing snow chain could bring
about adverse effect on automobile
manipulation, accordingly the speed of a
vehicle should not exceed 50 Km
/h(30mph )AK or in compliance with the
specified velocity limit( less than 50 Km
/h) by the manufacturer .if you heard the
chain

striking

vehicle body or

chassis ,immediately stop the vehicle
and fasten the chain When Using snow
chain , avoid sharp turn , impact
blow ,hurdling pit, wheel lockup and
braking , or follow the provisions by
chain manufacturer. The incorrect using
of Snow chain could gave rise to
interference between snow chain and
vehicle body.
