2. OVERVIEW
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit has the same code. When the ignition key with the integrated transponder is turned to
the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if correct, allows
your vehicle to start the engine.

4. START FUNCTION
1) Immobilizer Function
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the engine.
The transponder inside the key communicates with the immobilizer installed in the key box, and the
system permits the engine to start after confirming the encrypted coding from the engine ECU.
For the vehicle with the immobilizer, there can be a problem in starting the vehicle or the system
error:Immobilizer unit sends
encrypted code to
transponder (2)
Sends an encrypted signal to
unit as a response (3) Randomly transmitted code is changed to
an encrypted signal in immobilizer unit (4)
System compares signal from transponder and
encrypted signal in immobilizer unit (5)
When two or more immobilizer keys come into contact with (each) other(s).
When the key is close to any device sending or receiving electromagnetic fields or waves other
than Ssangyong products.
When the key is close to any electronic or electric devices such as lighting equipment, security
keys or security cards.
When the key is close to a magnetic or metal object or a battery. a.

Immobilizer and Warning Lamp ▶
This indicator comes on when the ignition key is
communicating with the engine control unit
(during engine starting) and goes out after
starting the engine.
When turning the ignition key to the "ON"
position, the ECU (engine control unit) transmits
the challenge message to the immobilizer unit.
(This is to verify whether the key is valid. If the
verification fails, it transmits re-verification signals
3 times for 2 seconds. If three re-verifications fail,
it stops verification and starts re-verification after
10 seconds.) (1)
ECUOnly when the two signals are identical, it recognizes the
key as the authorized one and transmits the positive
message to the ECU. (6)
The ECU enable the engine to be started. (7)
Do not drop or shock to the transponder in the key as it may be damaged.
With a damaged transponder, the engine cannot be started.
When you erase the code or register an extra key, please attend on the site.
In any cases, the immobilizer system can not be removed from the vehicle. If you attempt to
remove it and damage the system, starting will be impossible, so never attempt to remove,
damage or modify it.
The remote engine starter cannot be installed to the vehicle equipped with the immobilizer system. ·

3. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy days,
set the switch to the OFF position. Especially during the winter time, check if the wiper blades are not
frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield can
be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid when
the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -
-
-
-
When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly. It
could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition
switch OFF when not in use.
Irregular operation (abrupt operation) ▶
Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to work
irregularly. Therefore, in this case, replace the wiper blade with a new one. -
