Maintenance ▶
If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a malfunction
in the charge system including the battery. Therefore, carrying out the system check is needed.
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the battery
cables with the ignition key turned to ON or ACC position, several electric units can be damaged due
to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted with
soapy water. -

Do not move the shift lever to Neutral position while driving with the cruise control turned on.
Otherwise, it may result in system malfunction or accidents.
Always be prepared to use the brake or accelerator pedal for safe driving while the cruise control
system is running.
The actual speed can be different from the set speed momentarily when driving on a uphill or
downhill. So, it is recommended to disable the cruise control function on a uphill or downhill. hen
driving on a steep hill use the engine brake and foot brake properly to protect the vehicle system
and for a safe driving.
Ensure that the safe distance is maintained and use the brake pedal if needed. 1.

(1) Abnormal Cancellation of the Cruise Control
Sharp acceleration or deceleration
- 50 km/h faster than set speed
- 25 km/h faster than set speed for one minute
- 70 km/h slower than set speed
- 65 km/h slower than set speed for 3 minutes
When the cruise control lever is faulty.
When the brake switch and the brake light switch input signal are implausible. 1.

When the cruise control function is cancelled abnormally or intermittent problems occur, stop the vehicle
and turn off the ignition switch and remove the key to reset the system. After a while, turn on the ignition
switch again to operate the cruise control system.

7) Immobilizer Control
(1) 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 have 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 the vehicle to start the engine.
For details, refer to Chapter "BCM".

Key approval process ▶
When turning the ignition switch to ON position, the power is supplied to BCM and ECU. ECU
communicate with the immobilizer key to check if it is valid crypto code. If it is valid, ECU start to control
the engine when turning the ignition switch to START position.
The system has 10 seconds of valid time-out period. If the engine does not start in this period, the key
approval process should be done again.
