General safety regulations

To prevent personal injury and material damage to the vehicle,

observe the following:

WARNING

Risk of injury and accident by accidental engagement of gear

while engine is running.

♦ Before working on vehicle with engine running, shift se‐

lector lever into position “P” and apply parking brake.

Please note the following to avoid personal injury and damage to

or destruction of electrical and electronic components:
♦ Connect and disconnect measuring and testing devices only

with the ignition switched off.

Caution

Danger of destruction of electronic components when battery

is disconnected.

♦ Take the necessary measures when disconnecting the

battery.

♦ Disconnect battery only after the ignition has been switch‐

necting and connecting battery .

3.2

Safety precautions when working on ve‐

hicles with high-voltage system

Note

In the event of queries or uncertainties regarding the terms "“elec‐

trically informed person”, “high-voltage technician”, “high-voltage

expert”" or the hybrid system, the relevant importer must be con‐

tacted prior to the start of all work.

Before work on the high-voltage system is started, a high-voltage

technician must de-energise the high-voltage system ⇒  Electrical

system .
The types of work for which the high-voltage system has to be de-

energised are indicated in the list entitled “Work on the high-

WARNING

You can suffer an electric shock.
An electric shock can be fatal.
Observe  general  warning  instructions  for  work  on  the  high-

93 ; General warning instructions for work on the high-voltage

system .

♦ The system must first be de-energised by a high-voltage

technician before any work is done on the high-voltage

system and before any repair work is done on the body.

The types of work for which this is necessary are indicated

in the table “Work for which the high-voltage system must

be de-energised:”.

♦ All work on vehicles with a high-voltage system must only

be carried out by electrically instructed persons. The work

must be supervised by a high-voltage technician.

WARNING

Handling high-voltage cables:

♦ Do not support yourself or your tools on high-voltage ca‐

bles and their components.

♦ Work involving metal-removing, deforming and sharp-

edged tools in the vicinity of high-voltage components and

cables is prohibited.

♦ Work involving heat sources such as welding, soldering,

hot air and thermal bonding in the vicinity of high-voltage

components and cables is prohibited.

♦ High-voltage cables must not be extensively bent or

kinked.

♦ In the event of queries or uncertainties, contact your re‐

sponsible high-voltage technician (HVT).

which test and measuring equipment is

used

Please note the following if test and measuring equipment is re‐

quired during a road test:

WARNING

Accident hazard as a result of distraction and inadequate se‐

curing of test and measuring equipment.
Danger as a result of activation of front passenger airbag in

event of an accident.

• Operation of test and measuring equipment while driving

results in distraction.

• Greater injury hazard as a result of unsecured test and

measuring equipment.

♦ Always strap test and measuring equipment in place on

rear seat and have a 2nd person operate them.

box -J743-

WARNING

System is under pressure!

♦ The mechatronic unit for dual clutch gearbox -J743- has

a pressure accumulator that maintains a system pressure

of up to 60 bar.

♦ The cover of the mechatronic unit for dual clutch gearbox

-J743- and the pressure accumulator must not be opened.

Note

The pressure of the pressure accumulator is software-controlled and is set by means of the pump to a nominal

pressure of max. 60 bar. At a pressure of 60 bar the pump is switched off. If the pressure drops to 42 bar due

to gear shifting operations, the pump is switched on again. In the event of software errors the generated pressure

might amount to 75 bar. At 75 bar the pressure relief valve opens automatically.
