• Note national regulations.

1.2 Removing sealant

• Hydrochloric acid is created when PVC sealing material is heated to temperatures in excess of 180ºC.
• Remove PVC sealant with a rotating wire brush only or heat material with a hot air blower to max. 180ºC and remove with a spatula.
• Ensure that all enclosed areas are well ventilated or are provided with direct extractor facilities.

1.3 Arc welding and brazing

IMPORTANT: The extremely bright arc during welding may cause serious injury to the eyes if appropriate protective measures are not taken.

• Use a special welding screen* for the relevant welding method (MAG or MIG).
• Partition off the work bays with beam protection screens*.
• Use a welding-emissions extractor facility*.
• The welder must wear protective clothing* and gloves* which are suitable for welding (i.e. flame-proof).
• A fire extinguisher must be located within reach of the welding area.
• Do not carry out any welding work in the proximity of a fuel tank e.g. when it is installed.
• Note national regulations.

1.4 Working with chemical products (adhesive, cleaning agents, fillers, etc.)

Heed the manufacturer's material safety data sheets.

IMPORTANT: Handling chemical products may result in allergic skin and breathing reactions.

• Do not eat, drink or smoke while working with these products.
• Avoid direct contact with eyes and skin.
• Wear safety goggles, protective gloves and if necessary an apron.
• Ensure that all enclosed areas are well ventilated or extract fumes directly.
• Use a breathing apparatus with a suitable filter type when ventilation is insufficient.
• Wear impermeable protective clothing.
• Immediately change contaminated work clothing.
• After finishing work, wash your hands thoroughly and apply protective skin cream.
• Always keep an eye douche on hand, change the water regularly (once a month).
• Store bonding products in a secure cabinet only.
• Keep bonding products away from naked flames and other ignition sources.

First Aid

If product comes in contact with eyes, immediately flush with running water for about 10 -15 minutes. Seek the advice of eye specialist.

In the event of skin contact and where applicable an allergic skin reaction, clean the affected areas immediately with soap and water and then apply silicone-free skin cream. If necessary, consult a doctor.

If an adhesive product is swallowed, rinse mouth/parts of mouth thoroughly with running water. Drink 1-2 glasses of water. Do not induce vomiting. Consult a doctor.

After inhaling adhesive vapors ensure ample supply of fresh air. Stay calm. Keep air passages open. Consult a doctor.

Safety Information For Working On Vehicles With Automatic Engine Start-Stop Function (MSA)

WARNING: If the engine hood/bonnet contact is pulled upwards (workshop mode), the information "switch closed" is output. The automatic engine start-stop function is active.

An automatic engine start is possible.

Observe safety precautions when working on MSA vehicles

Before carrying out practical work on the engine, always ensure that the MSA functionality is deactivated so as to prevent automatic engine starting while work is being carried out in the engine compartment.

MSA function is deactivated by

• Deactivate MSA by means of button (1) in passenger compartment
• Open seat belt buckle and driver's door

Fig. 64: Identifying MSA Button

• Open engine bonnet/hood and ensure that engine hood/bonnet contact is not in workshop mode
  • Workshop mode
    A = 10 mm
  • Basic setting (engine hood/bonnet open)
    B = 7 mm
• To make sure that the engine hood/bonnet contact is at the basic setting, if necessary press the hood/bonnet contact up to the limit position before starting work and slowly release.
