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. -

5) ECO Cruise Control
ECO cruise is ready and ECO cruise indicator on the instrument cluster comes on when pushing down
the cruise control lever. To activate the ECO cruise mode, push down the cruise control lever again. To
cancel the ECO cruise mode while in operation, push down the cruise control lever again. The ECO
cruise mode is canceled and the indicator goes out.
What is ECO Cruise mode?
In this mode, the smooth acceleration to the set cruise speed can be achieved by optimized fuel
consumption.

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".

warning lamp)

Operation of charge warning lamp
ECU checks the generating voltage from alternator and circuit conditions and sends the warning lamp ON
signal to meter cluster through CAN line.Basic control logic according to the driving conditions
Engine ECU determines the engine loads according to the fuel injection volume and engine speed. It
charges the battery by increasing the generating voltage during deceleration. To improve the fuel
economy by reducing the alternator load during acceleration, engine ECU decreases the generating
voltage and consumes the battery voltage.
