INSPECT Check    
DANGER Risk of injury in the form of trapping or crushing, or even severing of limbs, if caught in windshield wiper mechanism  Always remove ignition key when working on windshield wiper mechanism. AS82.30-Z-0001-01A
NOTES When working on raised driver-side wiper arm (1) or front passenger side wiper arm (2) it has to be observed that they do not fall onto the windshield to prevent it from being damaged.    
1 Move wiper system from parked position IMPORTANT To do this, turn on ignition (circuit 15 or circuit 15R) and turn wiper switch to position "Two". After the wiper system has left the parked position, turn off ignition and turn back wiper switch to position "Zero".  
2 Manually position wiper system into reverse position IMPORTANT Distance between driver-side wiper blade and A-pillar (A) approx. 35 mm, distance between front passenger side wiper blade and A-pillar (B) approx. 350 mm.  
    IMPORTANT For left-hand drive vehicles, measured from the upper wiper blade end of the driver-side wiper blade (1) and the front passenger side wiper blade (2) to the inside of the left A-pillar.
For right-hand drive vehicles, measured from the upper wiper blade end of the driver-side wiper blade (1) and the front passenger side wiper blade (2) to the inside of the right A-pillar.
 
3 Remove wiper blades IMPORTANT See Operating Instructions  
4 Clean wiper blade mounts on driver-side wiper arm (1) and front passenger side wiper arm (2)    
5 Measure angle of incidence of driver-side wiper blade (1) and front passenger side wiper blade (2) to windshield and record NOTES When changing from reverse position to parked position it has to be observed that the driver-side wiper arm (1) and the front passenger side wiper arm (2) do not have any direct contact to the windshield to prevent it from being scratched. AR82.30-P-6000-01Q 
    IMPORTANT Cover driver-side wiper arm (1) and front passenger side wiper arm (2) with appropriate means.

IMPORTANT Notes on wiper arm adjustment   AH82.30-P-0001-01A
7.1 Adjust angle of incidence of driver-side wiper arm (1) or front passenger side wiper arm (2) in parked position In the event that the test values deviate from the tolerance range in reverse position or in parked position and reverse position: AR82.30-P-6100-01Q 
    IMPORTANT Distort driver-side wiper arm (1) or front passenger side wiper arm (2) by at least the value of the tolerance deviation in reverse position.  
    The specified adjustment values are only valid for left-hand drive vehicles. For right-hand drive vehicle, the particular sign has to be changed.
