JAC S1. Service manual — part 8

Air conditioner (evaporator and
blower unit)

Air conditioner is inside of the evap鄄
orator, which is back of the glove
box. This unit can reduce foreign ma鄄
terials that come into vehicle and fil鄄
ter with air.

Main points for operation院

音 When you get into the vehicle,
and the temperature is high, you can
open the window to discharge warm
air.
音 When using the air conditioner,
close all the windows to block the
heat outside of the vehicle.
音 When driving on jammed region
slowly, you should shift to low gear.
This can increase the engine speed
and the speed of air conditioner

compressor.
音 When driving on steep road, you
should turn off the air conditioner to
avoid engine overheat.
音 In winter or in the season when air
conditioner is not often used, the air
conditioner must be operated once a
month. That will help lubricant circu鄄
lation and keep the normal operation
of the system.

Caution院
音 The air filter should be re鄄
placed every year or each
20,000 km (12,000 miles).If the
vehicle runs on bad road,such

as dusty or cragged road, the
air filter should be checked a鄄
gain and again, and it should be
replaced when necessary.
音 If the ventilating air reduces
suddenly, you must ask the au鄄
thorized JAC dealer to check.

FM receiving station

Ionosphere

Characteristics of JAC vehicle

52

AM and FM signals are sent from
transmitting stations around the city.
After the antenna of the radio re鄄
ceives the signal, the sound will be
sent out from microphone. If high sig鄄
nal touches your vehicle, the radio
can operate exactly. If the signal is
low or unclear, it may be related to
the distance, and related to the
building, bridge and other structures
that block off signal.

AM receiving station generally has

better receiving effect than FM, be鄄
cause AM wave is transmitted at low
frequency. These low frequency
waves can follow the ionosphere of
earth curvature.
In addition, they can get round barri鄄
er to provide better signal. Thus, in
wide range, AM signals can be bet鄄
ter received than FM radio signals.

FM radio receives high frequency
signals that can not bend with the
earth curvature. So, FM radio can on鄄

ly receive signal which is near to
service station. In the same way, FM
signal will be influenced by high
building, high mounting or other bar鄄
rier. These reasons may lead to un鄄
clear sound. The following phenome鄄
na are normal; do not regard them as
radio's malfunction.

音 Sometimes the sound is strong,
sometimes the sound is weak --
when your vehicle is far from service
station, the signal will become weak

(that is to say, sometimes the sound
will be strong, sometimes it will be
weak). If case of such phenomena,
we recommend you to choose other
service station with stronger signal.
音 Vibration/mute-- If the FM signal
is weak, or there is huge barrier be鄄
tween receiving station and vehicle,
vibration/mute will exist.
Lowering the volume can help to re鄄
duce this phenomenon, till the sound
is clear.

音 Change service station--After FM
signal becomes weak, the frequency
that is near to the vehicle and has
stronger signal begins to act. This is
because your radio more easily re鄄
ceives clear signal. In such case,
please choose other service station
with stronger signal.
音 Cancel multi-layer signal-- Sig鄄
nals received from several directions
can lead to bad hearing effect. The
reason is that the direct and repeat鄄
ing signals come from same service
station, or two service stations having
close frequency send out signal at
the same time. In such case, please
choose other service station.

Use multi-net mobile phone and
bidirectional wireless communi鄄
cation unit

If you use multi-net mobile phone in
the vehicle, audio device may send
out noise. That does not indicate fault
of the audio device. At this time,
please use the multi -net mobile
phone far away from audio device.

Caution院
音 If you use multi -net mobile
phone or radio in the vehicle, ex鄄
terior antenna must be suited for
the vehicle configuration. If you
use mobile phone or radio by in鄄
terior antenna, electric system of
the vehicle will be disturbed, and
safety system will be affected, too.

Protecting disk
Method for touching with hand

Seize the disk as per the figure, and
do not toss about the disc. When
seizing the disk, do not leave finger
print on the surface of the disc. If
there is scratch on the surface, the
content will not be completed. Do not
adhere tape, paper or label on the
disk; do not scrabble on the disk; do
not play bad, distorted or scratched
disc; otherwise the player will be

damaged seriously.

Storage

When the disc is not used, please
place it in the disk box and store in a
place where sunshine, high temper鄄
ature and high humidity can be
avoided. After the disc is automati鄄
cally ejected from player, do not use
your hand to hold or pull it out. After
inserting the disk or pressing the exit
button, do not pull out the disc from
the player immediately. If the disc is
pulled out before finishing the opera鄄
tion, it will rotate in the unit and will
be damaged. When the player is not
in the panel or the main switch is
turned off, do not try to insert disk.

Keeping the disk clean

Finger print, dust or dirt can cause
bad play. So, please use clean dish
cloth to keep it clean. If the surface
is too dirty, please use neutral deter鄄
gent to clean out.

Characteristics of JAC vehicle

When the ignition key is in "ON" or "
ACC" position, if you turn on the ra鄄
dio, the vehicle will receive AM and
FM signals from rear side glass.

Caution院
音 Do not clean the inner rear
middle glass with cleaning a鄄
gent having grinding function, or
scrap deposit with scraper.

Keep the normal operation of the
ventilation device, and the air suction
of the ventilation system must be set

Driving your vehicle

Warning院

Precaution about waste gas from
engine.
音 Waste gas discharged from
engine is very harmful to body,
and can even cause death.
Therefore, when discharged gas
is smelled in the vehicle, open
the window immediately. Such
waste gas contains carbon
monoxide, a colorless and
tasteless gas, which may result
in suffocation or even death.
音 Determine there is no leak鄄
age from the discharge system
When the vehicle is lifted for re鄄
placing engine oil or for other
purposes, check the discharge

system. If there is abnormal
noise from the discharge system
or the vehicle bottom has been
hit during driving, promptly have
the authorized JAC Dealer
check the discharge system.
音 Do not let the engine run in a
confined area
The engine must be stopped
during parking in garage. To
prevent moving of vehicle, do
not run the engine in the
garage.
音 Avoid idling the engine for
long time when there are pas鄄
senger in the vehicle. If people
are to stay in the vehicle for long
time with the engine running, set

the air admission device at "
Fresh" position and set the fan
speed to high, to allow fresh air
outside to enter the vehicle.
When the back door cannot be
closed because of the loaded
objects, take care during driv鄄
ing.
1. Close all windows.
2. Open the exhaust port.
3. Set the air intake pushbutton
at "Fresh" position, and the draft
pushbutton at "Foot" or "Face"
and a high speed for the fan.

in the middle of the windscreen, to
remove snow, ice, leaves or other
substances.

Precautions before starting the
engine:

1 . Check all tires, fuel, water and
other equipment of the vehicle that
may lead to an accident.
2. Check the hand brake after enter鄄
ing the vehicle.
3. Check all windows and lights for
cleanliness.
4. Check the inside and outside rear
view mirrors for cleanliness.
5. Check the positions of seats,
backs and seat head rests.
6. Lock all doors.
7. Check your fastened travel of your
safety belt and the safety belts of
other passengers.
8. Turn off lights and other compo鄄
nents not used.
9. When the ignition switch is at "ON"

position, all necessary warning lights
should operate, and confirm there is
sufficient fuel.
10. When the ignition key is at "ON"
position, check the functioning of the
warning light and the bulb.

Start the engine with combined
ignition switch

音 For vehicle with manual gears,
first set the shift lever to neutral, and
step on the clutch pedal.
音 For vehicle with automatic gears,
set the shift lever at "P" (parking).
音 To start the engine, insert the ig鄄
nition key and turn it to "START" po鄄
sition. The engine will start to run
when it is released. Do not leave the
ignition switch at "START" for over 15
seconds.

Warning院

音 Our vehicles are more likely
to collision than other vehicles.
音 The ground clearance of our
vehicle high, permitting it to run
over small path and other
cross -country ground. Avoid
sharp turns or movement, as
improper operation may result in
overturning.
音 Passengers failing to fasten
the safety belt are exposed to
the risk of death in case of seri鄄
ous collision.
