Danger of electric shock
G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high- voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. All of the vehicle's high-voltage electrical sys-
tem components are marked with yellow
warning stickers which warn you about high
voltages. The cables of the vehicle's high-
voltage electrical system are orange.
When towing a vehicle after an accident, be
sure to observe the following sections:
R Transporting the vehicle (Y page 295)
R Towing the vehicle with the front axle raised
(Y page 295)
R Towing a vehicle with both axles on the
ground (Y page 294)
Read the important safety instructions on
towing away (Y page 292).
The ignition must be switched off when car-
rying out general tasks, such as changing
bulbs or checking the coolant level. Automatic switching off of the vehicle's
high-voltage electrical system If the restraint systems are activated during
an accident, the vehicle's high-voltage elec-
trical system is automatically deactivated.
This is to ensure that you do not come into
contact with high voltage.
Automatic protection from switching
on of the vehicle's high-voltage electri-
cal system The vehicle's high-voltage electrical system is
not activated when the vehicle is started if:
R a serious electrical insulation malfunction
is detected in the vehicle's high-voltage
electrical system.
R an electrical connection in the vehicle's
high-voltage electrical system is discon-
nected.
Automatic switching off of the charging process The charging process is deactivated automat-
ically if:
R the high-voltage battery is fully charged
The charging process is interrupted automat- ically if:
R a serious electrical insulation malfunction
is detected in the vehicle's high-voltage
electrical system.
R an electrical connection in the vehicle's
high-voltage electrical system is discon-
nected.
High-voltage switch-off device !
The high-voltage system must only be
switched off at vehicle standstill by spe-
cially trained service engineers. Otherwise
the high-voltage system may be damaged. Int
roduction
23 Z

Your vehicle is equipped with a high-voltage
switch-off device :which can be used to
switch off the vehicle's high-voltage electrical
system.
Mobile phone antenna !
It is not permitted to retrofit a mobile
phone antenna.
Trailer tow hitch !
Retrofitting a trailer tow hitch is not per-
missible.
Warning Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your
vehicle may not be heard by other road users
until it is very close to them, or it may not be heard at all. This is particularly the case if
other road users have not yet seen your vehi- cle but are instead relying on hearing. Drive
with particular care, allowing for the possibil-
ity that other road users may behave unpre-
dictably.
The vehicle is equipped with a sound gener-
ator. The sound generator is activated so that
other road users can hear your vehicle better. The sound generator is activated at speeds of under 20 mph (30 km/h) and switches off
automatically at higher speeds. Declarations of conformity
Vehicle components which receive
and/or transmit radio waves USA:
"The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly approved by the party responsible for com-
pliance could void the user’s authority to
operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ-
ing interference that may cause undesired
operation of the device." Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. G
WARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result, the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter 24

Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may
light up continuously or flash. In addition,
there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 7seat belt
warning lamp lights up for six seconds each
time the drive system is started. If the front
doors are closed and the driver or front-
passenger seat belt has not been fastened,
the 7 seat belt warning lamp lights up
again after the six seconds. As soon as the
driver's and front-passenger seat belts are
fastened or a front door is opened again, the
7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the drive system is started, an additional
warning tone will sound. The warning tone Occupant safety

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes G
WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special- ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of your
passenger to have deployed air bags replaced and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash. G
WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera- tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist workshop.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear a
bang, and a small amount of powder may also be released. The 6restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it may cause short-term breathing difficulties in
people with asthma or other respiratory prob-
lems. To avoid this, you may wish to get out of
the vehicle or open the windows as soon as it is safe to do so.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) contain perchlorate mate- rial, which may require special handling and
regard for the environment. National guide-
lines must be observed during disposal. In
California, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm .
Method of operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the
Emergency Tensioning Devices during a fron- tal or rear collision.
An Emergency Tensioning Device can only be
triggered, if:
R the ignition is switched on
R the components of the restraint system are
operational; see "Restraint system warning
lamp" (Y page 41)
R the belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of the restraint system are activated independ-
ently of each other in certain frontal collision
situations: 54
