Position of ignition key

音 "START"
The engine will start to run when the
ignition key is turned to this position.
Release the ignition key after the en鄄
gine starts running.
音 "ON"
When the ignition key is at "ON" posi鄄
tion, the engine will start to ignite and
all components will start to work. If
the engine does not work, the ignition
key should not be kept at "ON" posi鄄
tion, as this will result in spontaneous
discharge and may destroy the igni鄄
tion system.
音 "ACC"
When the ignition key is at "ACC" po鄄
sition, some electric devices (radio)
can work.
音 "LOCK"

The ignition key can be inserted or
pulled out at this position.
To prevent theft, the steering wheel
can be locked using the ignition key.

Pull out the ignition key

Warning院

音 Do not turn off the engine or
remove the key when the vehicle
is running, as the steering wheel
is close to the ignition key.
1. Turn the ignition key to "ACC"
position.
2. Press and turn the ignition key
from "ACC" to "LOCK" position
counterclockwise.

Caution院
音 When the shift lever is moved
from 5th gear to 4th gear, it is
possible to enter the 2nd gear
by mistake. This will cause the
engine speed to increase and
the speedometer will enter the
red area.

clutch pedal and then release it
slowly. Frequently use the clutch
pedal before it returns to the original
place. During drive, do not rest your
foot on the clutch pedal. Do not park
the vehicle on the upper slope by
stepping on the clutch.

Precautions in driving

音 Never let the vehicle run under
inertia without engaging in gear
when going down a slope, as this is
extremely dangerous. You must run
the vehicle by engaging the trans鄄
mission.
音 Never keep the brake pedal
stepped on for long time. This will
overheat the brake and cause fault.
When going down a slope, decrease
the speed and engage into a low

gear. After completing this proce鄄
dure, the engine brake device will
help you decrease the speed.
音 Run the vehicle at decreased
speed after engaging in a low gear.
This can avoid over-speeding of en鄄
gine.
音 Please reduce the speed in strong
wind, as it will be easier to control
your vehicle at reduced speed.
音 Confirm that the vehicle is com鄄
pletely stopped before engaging the
reverse gear. To engage into the re鄄
verse gear, step on the clutch and
set it to neutral, and engage into the
reverse gear after 3 seconds.
音 When driving on a slippery
ground, take care during braking,
acceleration and shifting gear, as

sudden change of speed will cause
slipping of tires and loss of control.

Anti-blocking system

The anti -blocking system (ABS) is
designed to prevent blocking of
wheel in case of emergency braking.
The ABS control system can test the
vehicle speed and control pressure.
Therefore, the ABS can increase the
control ability of vehicle in case of e鄄
mergency or when driving on slip鄄
pery roads.

Reduce the speed when driving on
such roads. It is not permissible to
test the function of ABS by fast driv鄄
ing or making sharp turns.

Electric Brakeforce Distribution
(if installed)

The EBD is a unit to replace the ratio
valve which is used to keep the vehi鄄
cle running steadly during braking.In
the condition of normal braking, the
unit can balance the wheel speed; In
the conelition of difficult braking be鄄
cause the weight of vehicle accumu鄄
late front wheel, the rear wheel brake
need less forle.EBD can keep the
forle of braking rear wheel by using
the incease air pressure valve or de鄄
crease air pressure valve of ABS, to
keep the wheel steadly running and
brake effectively.

Note院
音 When the ABS system is oper鄄
ated, there may be slight vibration
when the brake is stepped on.
Noise from the engine may also
be heard when the brake is ap鄄
plied. This is normal, indicating
the normal functioning of the anti-
blocking system.

Warning院

音 It is impossible for the ABS to
prevent accident when driving on
a dangerous road. Although it can
provide effective control in case of
emergency, it cannot completely
avoid accident. Therefore, keep
space between vehicles, and
drive slowly when not on highway.
音 Driving on rugged ground or
ground with broken stones or snow.
音 Driving with chain fitted.
音 Driving on a highway with un鄄
even surface.

65

Tension control system (TCS)
(if installed)

For driving on a slippery ground, the
tension control system (TCS) can lim鄄
it the slippery of tires and to enable
steady start of the vehicle. This sys鄄
tem may increase the weight of the
vehicle and permit safe turning at
high speed.

Reducing accident

When the vehicle is started on a
slippery ground or turn at high
speed, this system can limit the high
speed rotation of wheels and avoid
loss of balance with wheels.

Suggestions

TCS cannot increase the brake per鄄
formance. Please reduce the speed

before making turns.

TCS mode

The indicators on the instrument
panel will stop displaying in TCS
mode.

Caution院
音 The TCS can control sliding
when the TCS indicator is flashing.
When the road is slippery or the
vehicle is running at high speed,
release the accelerator pedal and
keep the vehicle steady.

Warning院

音 The TCS system is a compo鄄
nent of the vehicle; and all
guarding devices should be put
into service in winter or on slip鄄
pery roads.

Note院
音 1) The TCS mode will be au鄄
tomatically started when the en鄄
gine is started again after being
stopped.
2) You may feel slight jittering of
the vehicle after appropriate ad鄄
justment of the tension control
device. This is only the effect of
control of brake and not an
anomaly.
3) When the engine is started,
you can hear a click noise from
the engine compartment, and
this is only the sound from the
tension control device.
4) The accelerating device may
not function when the vehicle is
running on muddy or snowy
ground.

Indicator and warning light

The indicators will flash when the ig鄄
nition key is turned on or the vehicle
is started. If it does not flash, have it
checked by the authorized dealer.
The warning light will indicate a warn鄄
ing in case of anomaly with the TCS
device.
When the TCS indicator works, park
the vehicle at a safe place. Start the
engine again to check if the TCS in鄄
dicator continues to work.
If the indicator still works after the en鄄
gine is started, have it checked by
the authorized JAC dealer.

Safe driving of all wheel drive
vehicles

(1) Fasten the safety belt.
(2) Never attempt to make a try when
the vehicle design and driver skill is
not suitable for running on cross -
country ground.
(3) Reduce the speed in strong wind,
as your vehicle is likely to be affect鄄
ed by strong wind. Reducing the
speed can avoid loss of control.
(4) Check the brake system after
driving in rainy days or on a road
with slurry. Drive slowly and step on
the brake pedal in several times until
it works normally.
(5) Never drive on road with much
water (for example brooks, rivers and
lakes).

(6) The braking distance between an
all wheel drive vehicle and a four -
wheel drive vehicle is slightly differ鄄
ent, therefore proper space between
vehicles should be kept when driving
on a road extremely difficult to drive.
(7) The driving torque is controlled
by four wheels, therefore the tire
quality can directly affect the driving
condition of the all wheel drive vehi鄄
cle. Determine the quality and size of
all tires.
音 All tires should be replaced at the
same time.
音 Turn the tires and check the air
pressure of tires under normal condi鄄
tions.
(8) The tire chains should be fitted on
the front tires.

Note院
音 When the TCS is flashing, the
tension control system will auto鄄
matically reduce the driving force.

67

(9) If a front or rear wheel is trapped
in a pit, never roughly turn the wheel,
as this may damage the all wheel
drive system.

Limited-slip differential (if in鄄
stalled)

The limited-slip differential controls on鄄
ly the rear wheels. The functions of the
limited-slip differential are as follows:
Similar to an ordinary differential, it
can make the speed of wheels on
two sides different at turning. A limit鄄
ed-slip differential differs from an
ordinary one in that if the driving
force for the wheel on one side is
lost, it can provide more driving force
to the rear wheel on the other side.

Use the brake correctly

Caution院
音 When an all wheel drive vehi鄄
cle is lifted by a lifting device,
never start the engine or turn the
wheel. Contacting a rotating
wheel with the ground is dan鄄
gerous and may result in dam鄄
age to the vehicle.
音 If the front or rear wheel
starts to rotate in the pit, the ac鄄
celerator pedal may be stepped
on. But running the engine at
high speed for long time should
be avoided, as this may dam鄄
age the all wheel drive system.

Warning院

音 Avoid sharp turning.
音 Never turn the steering wheel
at high speed.
音 Loss of control when driving
on expressway may lead to
overturning
音 In case of serious collision,
passengers not with safety belts
fastened will suffer higher death
rate than those with safety belts
fastened.
音 The usual cause of loss of
control is disengaging of two or
more wheels or excessive turn鄄
ing by the driver.
音 Never turn sharply for leaving
the express lane. Reduce the
speed before changing lanes.

Warning院

音 Never load goods higher than
the back seat cover, or the
overloaded goods may damage

JAC dealer.
音 Never run the vehicle down
slope before setting the gear.
Keep the gear and use the brake
to run at reduced speed. Use a low
gear to get better braking effect.
音 Never keep the braking pedal
stepped on over long time, and
do not rest your foot on the brak鄄
ing pedal over long time during
driving. This will overheat the en鄄
gine and lost the effective func鄄
tion, and will also wear the brake
components.
音 In case of tire leakage during
driving, use the brake to keep the
vehicle steady. Park the vehicle at
a safe place when it is slowed

down to a certain extent.
音 In some cases, the manual
brake may be found frozen at
startup, such as snow or ice de鄄
posit around the vehicle or the
rear brake, or when the brake has
got wetted. If there is the possi鄄
bility of freezing, set the shift gear
to the reverse position (manual
transmission), and block the rear
wheel to prevent the vehicle from
rolling.
音 Do not keep the accelerator
pedal stepped on over long time
when going up slope. This may
overheat the transmission. Please
use the foot brake or parking
brake.

in an emergency braking or an
accident.
音 After parking, apply the manu鄄
al brake and confirm that the
manual brake indicator is lit.
音 Ground with water may wet the
brake. The brake may also get
wet during vehicle cleaning. Driv鄄
ing a vehicle with wet brakes is
extremely dangerous, as such
brakes cannot accurately brake
the vehicle or may sway the vehi鄄
cle to one side.To dry the brake,
increase the temperature until it
can function normally. If it cannot
be restored, stop the manipula鄄
tion and contact the authorized
