To prevent damage to the hybrid drive
system please observe the following
instructions:
R only deactivate the hybrid drive system
manually in the following situations.
R work on the hybrid drive system may only
be carried out at a qualified specialist
workshop, even when it has been deac-
tivated manually.
Deactivate the hybrid system manually if:
R the 6 restraint system warning lamp in
the instrument cluster lights up after an
accident
R the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
R the vehicle is badly damaged and has to be
towed or transported
X If possible, move the vehicle out of the
danger zone: shift the transmission into
position N.
X Release the electric parking brake.
X Roll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
The vehicle is locked automatically when the
ignition is switched on and the wheels are
turning. There is therefore a risk of being
locked out if the vehicle is being pushed or
tested on a dynamometer.
X Switch the ignition off.
X Shift the transmission to position P.
Apply the electric parking brake
(Y page 220).
Secure the vehicle against rolling away
(Y page 465).
X To use the high-voltage switch-off
device: open the bonnet. X
Press release clip :in the direction of the
arrow and pull it out.
X Pull high voltage switch-off device ;apart
until it engages in the stop position.
If the hybrid drive system has been deactiva- ted due to reasons mentioned above, have it
checked at a qualified specialist workshop
before reactivation.
High-voltage battery G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceeda critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
WARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with the skin, eyes or clothing. Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery. If the
vehicle is idle for lengthy periods leave the Hybrid vehicles

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 28). Key
Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double lock function by deactivat-
ing the interior motion sensor (see the sepa-
rate COMAND Online or Audio 20 operating
instructions). The doors can then be opened
from the inside after the vehicle has been
locked from the outside. The anti-theft alarm
system is triggered if the door is opened from
the inside. Switch off the alarm (Y page 90).
All countries: G
WARNING
If children are left unsupervised in the vehicle, they can:
R open doors and endanger other persons or
road users
R climb out and be injured by the traffic
R operate vehicle equipment and, for exam-
ple, trap themselves.
Children could also set the vehicle in motion, for example by:
R releasing the parking brake
R shifting the automatic transmission out of
park position P
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. Always
keep the key out of reach of children. G
WARNING
If you attach heavy or large objects to the key, the key could be unintentionally turned in the
ignition lock. This could cause the engine to
be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key into the ignition lock.
! Keep the key away from strong magnetic
fields. Otherwise, the remote control func-
tion could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the key: R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
Vehicles with KEYLESS-GO start function: do not keep the key in the luggage compart- 94

Starting procedure using the Start/
Stop button The Start/Stop button is only available on
vehicles with KEYLESS-GO or the KEYLESS-
GO start function.
The Start/Stop button can be used to start
the vehicle manually without inserting the key
into the ignition lock. The key must be in the
vehicle and the Start/Stop button must be
inserted in the ignition lock. This mode for
starting the engine operates independently of
the ECO start/stop automatic engine start
function.
You can start the engine if a valid key is in the vehicle. Switch off the engine and always take
the key with you when leaving the vehicle,
even if you only leave it for a short time. Pay
attention to the important safety notes. X

General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pull-
ing away.
The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking feature, see the Digital Owner's Manual.
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the
parking lock released. If you do not depress
the brake pedal, the DIRECT SELECT lever can still be moved but the parking lock remains
engaged.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
