4) Basic Inspection
(1) Horn operation
Listen for the horn sound when pressing the horn pad on the steering wheel. -
(2) Brake operation
Check if there is any abnormal noise, unusually long braking distance, or uneven braking force. If the
brake warning lamp does not go out even after starting the engien or are flashing during driving,
have the brake system checked immediately.
Check the brake pipes and hoses for connection, oil leak, crack or interference after changing the
position of tires. When replacing the tires, check the brake disc for surface condition and wear.
Check the parking brake cable and brake operation. Shorten the checking interval if the parking
brake is used frequently. -

-
(3) Exhaust system
Be aware to any changes in sound or smell from the exhaust system. These may be caused by leak or
overheat. Have the exhaust system checked and repaired immediately.
Inspect the exhaust system including catalytic converter. Inspect all the components and body frame
near the exhaust system. -
-
(4) Tires
Unusual vibration of the steering wheel and seats or pulling to one side on the straight and level roads
may indicates the uneven tire inflation pressure or poor wheel balance. -
(5) Steering and suspension system
Inspect the front and rear suspension and the steering system for damage, looseness or missing
parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for
connection, leak, crack and chafing. Inspect the drive axle boot and seals for damage, tear or leak.
Replace or repair the system if necessary. -
(6) Engine oil
Check the oil level when the engine is still warm and add the specified engine oil if necessary. -
(7) Coolant
Check the coolant level in the coolant reservoir, coolant conditions (contamination, foreign material),
and hoses for damage and leak. Replace or add the Ssangyong genuine coolant, if needed. -
(8) Engine drive belt
Check all drive belts on the engine for wear, crack and looseness. Retighten or replace the belt, if
needed. -

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. -

Measuring the voltage drop between lines
Measure the voltage drop between alternator B+ and battery B+. -
Specified valuebelow 0.3V
If the value is out of the specified value, check the terminal and clamp for looseness.
Checking the charge warning lamp
Check if the charge warning lamp goes out.
If the charge warning lamp does not go off, inspect the electric circuit.
Start the engine and check if the charge warning lamp keeps off. 1.

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.
