1.1 Safety Precautions when Working on
Fuel Supply System
Note the following When Working on the Fuel System:
WARNING
Very hot fuel can cause burns.
♦ In extreme cases, the temperature of the fuel lines and fuel
can reach up to 100 °C (212 °F) after stopping the engine.
Let the fuel cool down before opening any line connec‐
tions, otherwise there is a danger of scalding.
♦ Wear safety gloves.
♦ Wear protective eyewear.
There Is a Risk of Injury Due to the Fuel Being under Pressure.
The fuel system is under pressure. Injuries are possible from fuel
spraying out.
Before opening the fuel system:
– Wear protective eyewear.
– Wear safety gloves.
– Reduce the pressure: place clean cloths around the connec‐
tion point and carefully open the connection point.
Risk of a Fire Due to Leaking Fuel.
When the battery is connected, the door contact switch activates
the fuel pump when opening the driver door. Leaking fuel can
ignite and start a fire.
– Before opening the fuel system, interrupt the power supply to
the fuel pump.

1.2 Safety Precautions when Working on
Vehicles with Start/Stop System
There Is a Risk of Injury Due to the Engine Starting Unexpectedly.
The engine can start unexpectedly on vehicles with an activated
Start/Stop System. A message in the instrument cluster indicates
whether the Start/Stop System is activated.
– Deactivate the Start/Stop System: switch off the ignition.
1.3 Safety Precautions during Road Test
with Testing Equipment
There Is a Risk of Injury Caused by Unsecured Testing Equip‐
ment.
If the front passenger airbag deploys during an accident, unse‐
cured testing equipment becomes a dangerous projectile.
– Secure the testing equipment on the rear seat.
or
– Have a second technician operate the testing equipment on
the rear seat.
1.4 Safety Precautions when Working on
Cooling System
Risk of Scalding Due to Hot Coolant
The cooling system is under pressure when the engine is warm.
Risk of scalding due to hot steam and hot coolant.
– Wear safety gloves.
– Wear protective eyewear.
– Reduce the pressure by covering the coolant expansion tank
cap with a cloth and carefully opening it.
