RISK OF DEATH, RISK OF EXPLOSION/RISK OF FIRE, RISK OF INJURY & RISK OF POISONING - AS82.10-Z-0001-01A
Do not come into contact with parts that are under high voltage. Persons with active electronic implants
(e.g. heart pacemakers) must never work on xenon headlamps. Switch off entire lighting system. Wear
insulated safety shoes, safety glasses and protective gloves. Remove highly inflammable materials from
the hazard area. Ensure sufficient ventilation in the working area.
Potential risks
Risk of death
Due to the high voltages involved, contact with live components at the xenon headlamps could be life
threatening!
Electric shocks can cause fibrillation of the heart or even cardiac arrest.
In addition, respiratory muscles may cramp up and result in respiratory failure.
Serious, possibly life-threatening, brain function disruptions are also possible.
It ma
y take a few minutes for the consequences of an electrical shock to manifest themselves.

Risk of explosion/risk of fire
Highly flammable materials in the vicinity of damaged, energized xenon bulbs may result in explosion or cause
fires.
Risk of injury
UV light may escape when operating xenon bulbs not properly installed in the xenon headlamps. This UV light
may cause damage to the eyes (conjunctival infection) and to skin burns (sunburns) if skin is unprotected.
In both intact or faulty xenon headlamps, hot or glowing components may cause serious burn injuries if they
come into contact with unprotected skin or eyes.
Glass splinters produced by the destruction of xenon bulbs may cause cut injuries in unprotected skin and
unprotected eyes.
Risk of poisoning
When xenon bulbs are destroyed, serious health problems may be caused if the mercury vapors produced are
inhaled or if mercury compounds or toxic salts are ingested or absorbed through the skin. Possible
consequences include nausea, vomiting and gastrointestinal disruptions as well as degradation of the kidneys
and the central nervous system. Skin and eye damage may also result.
Safety precautions/instructions
Persons with electronic implants (e.g. pacemakers) must never work on xenon headlamps.
Wear safety shoes (with rubber soles).
Prior to working on xenon headlamps (e.g. replacing parts, hooking up test equipment, etc.), the complete
lighting system must be switched off and the xenon headlamps must be disconnected from the on-board
electrical system.
If the xenon headlamps are switched on, never touch components under high voltage.
If the xenon headlamps are switched on, maintain a clearance of at least 30 mm to components under high
voltage.
Avoid all contact with hot components.
Wait at least 3 min after switching off xenon bulbs before touching them.
Do not damage or destroy xenon bulbs.
Safety precautions/instructions
Never operate xenon bulbs unless they are properly installed in xenon headlamps with UV-absorbing
headlamp lenses.
Keep all highly flammable materials away from working area.
Wear suitable protective gloves and safety glasses.
Ensure that the workplace is sufficiently ventilated.

First aid measures
Electrical shock
Switch off current, bring injured person to safety.
Immediately notify an emergency physician.
Perform mouth to mouth respiration, if necessary.
Perform cardiopulmonary resuscitation, if necessary.
Burn injuries
Cool affected skin area with cold water.
Cover burn wounds with sterile dressing.
Consult a physician.
Cut injuries/skin injuries
Stop the bleeding.
Dress cut/skin injury.
Consult a physician.
Foreign object in eye
Cover affected eye with a sterile dressing.
Cover both eyes to calm them.
Consult an eye doctor immediately.
Eye contact with mercury vapors/toxic salts
Flush eyes with lukewarm water.
Cover eye with sterile dressing.
Consult an eye doctor immediately.
Eye contact with UV light
Consult an eye doctor immediately.
Poisoning caused by inhaling mercury vapors
Take victim to fresh air.
Consult a physician immediately.

Consult a physician immediately.
Always consult a medical service or physician after administering first aid.
INJURY HAZARD FROM PINCHING AND CRUSHING, IN EXTREME CASES EXTREMITIES CAN EVEN BE CUT OFF
WHEN CAUGHT IN WINDSHIELD WIPER MECHANISM. - AS82.30-Z-0001-01A
Always remove ignition key before working on windshield wiper mechanism.
Injury hazard
When working in the area of the windshield wiper mechanism with the ignition key in position "1" or "2" the
wiper arm or wiper linkage can be pushed out of its end position and start running unintentionally . This can
result in severe injuries by cutting, pinching or crushing body parts.
Rules of behavior/protective measures
Always remove ignition key before working on windshield wiper mechanism.
Secure operating range of mechanism against reaching in.
Keep sufficient distance away from moving parts.
Supervise hazard area.
Wear tight fitting clothing and hair net.

82 119 We receive at the diagnostic
centers of the plants more and
more xenon control units and
xenon lamps which are o.k.
To avoid this high number of
problem parts with no
reproducible faults, we would ask
you to use the following
procedure for troubleshooting:
1 Perform diagnosis according to
instructions in WIS.
Model 202, 208, 210AD82.10-P-1001AZ
If the fault cannot be
recognized or the faulty
component determined: ?
2 Interchange the xenon lamps
(right to left).
For the time being do not
replace system components.
If the fault of the xenon lamp
still exists: ?
3 Remove/install/replace xenon
lamp.
If the fault remains in the
headlamp the cause may be the
xenon control unit or a fault on
the vehicle side.
We are aware of the fact that
this procedure may possibly lead
to another stay in the workshop o
f
the vehicle in question.
However, we see no other
alternative if the redebiting of
warranty and goodwill costs is to
be avoided.
