3 Safety precautions
3.1 Working on the fuel system
When working on the fuel system note the following warnings:
WARNING
The fuel system operates at extremely high pressure. This can
cause injury.
♦ The fuel pressure in the high-pressure section of the in‐
jection system must be reduced to a residual pressure
prior to opening the system.
♦ Wrap a clean cloth around the connection and carefully
loosen the connection to allow the residual pressure to
dissipate.
– Procedure before opening high-pressure section of injection
system ⇒ Rep. gr. 24 .
Observe the following to prevent injuries to persons and damage
to the injection and ignition system:
♦ Always switch off the ignition before connecting or discon‐
necting electrical wiring for the injection or ignition system or
tester cables.
♦ Always switch off ignition before washing engine.
♦ Faults are stored in engine control units if electrical connectors
were unplugged and engine was started: „Generate readiness
code“ in „Guided Functions“ ⇒ Vehicle diagnostic tester .
Caution
To prevent irreparable damage to the electronic components
when disconnecting the battery:
♦ Observe notes on procedure for disconnecting the battery.
♦ Always switch off the ignition before disconnecting the
battery.
– Disconnect battery ⇒ Rep. gr. 27 .
3.2 Procedure before opening high-pres‐
sure section of injection system
WARNING
♦ The injection system consists of a high-pressure section
(maximum approx. 120 bar) and a low-pressure section
(approx. 6 bar).
♦ The fuel pressure in the high-pressure section must be
reduced to a residual pressure of approx. 6 bar prior to
opening the system. Procedure ⇒ Rep. gr. 24 .

3.3 Working on the cooling system
When working on the cooling system note the following warnings:
WARNING
Hot steam/hot coolant can escape - risk of scalding.
♦ The cooling system is under pressure when the engine is
hot.
♦ To allow pressure to dissipate, cover filler cap on coolant
expansion tank with cloth and open carefully.
Caution
Overheating can occur if the filler cap is not fitted properly.
♦ The filler cap must engage positively and audibly when it
is closed.
3.4 Using testers and measuring instru‐
ments during a road test
Note the following if testers and measuring instruments have to
be used during a road test:
WARNING
Accidents can be caused if the driver is distracted by test
equipment while road-testing, or if test equipment is not prop‐
erly secured.
Persons sitting in the front passenger's seat could be injured if
the airbag is triggered in an accident.
• The use of test equipment while driving causes distraction.
• There is an increased risk of injury if test equipment is not
secured.
♦ Test equipment must always be secured on the rear seat
with a strap and operated from the rear seat by a second
person.
3.5 Working on the exhaust system
When working on the exhaust system please note the following:
Caution
Avoid damage to flexible joint.
♦ Do not bend flexible joint more than 10°.
