Activating HOLD X
Make sure that the activation conditions
are met.
X Depress the brake.
X Depress the brake again quickly until
HOLD appears in the display.
HOLD is activated. You can release the
brake pedal.
i If depressing the brake pedal the first
time does not activate HOLD, wait briefly
and then try again. G
Risk of accident
The vehicle's brakes are applied when
HOLD is activated. For this reason, deacti-
vate HOLD if the vehicle is to be set in
motion by other means (e.g. in a car wash
or by towing).
Deactivating HOLD HOLD is deactivated if:
R
you
accelerate when the selector lever is in
position D or R
R you move the selector lever to position P
R you release the brakes completely and
apply them again with a certain amount of pressure until the
HOLD message in the
multi-function display goes out G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD
must never be operated or deactiva-
ted by a passenger or from outside the
vehicle.
HOLD does not replace the parking brake
and must not be used for parking.
The HOLD braking effect is cancelled and
the vehicle can start moving if:
R HOLD is deactivated by depressing the
accelerator pedal or the brake pedal
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure
R the electrical system in the engine com-
partment, the battery or the fuses are
tampered with
R the battery is disconnected G
Risk of accident
If you wish to leave the vehicle or park it,
deactivate HOLD and secure the vehicle
against rolling away. You will see a warning message in the multi-
function display if HOLD is activated and:
R
the
driver's door is opened and you release
the seat belt
R the ignition is switched off
R the bonnet is opened
Selector lever in park position
X Move the selector lever to P
to prevent the
vehicle from rolling away.
HOLD is deactivated. The warning message
in the multi-function display goes out.
A horn will also sound at regular intervals if
HOLD is activated and you:
R stop
the engine and open the driver's door
R open the bonnet
The horn draws your attention to the fact that
the vehicle has been parked while HOLD is
still activated. The sound becomes louder if
you attempt to lock the vehicle. The vehicle
is not locked until HOLD is deactivated.
i If the ignition has been switched off, the
engine cannot be restarted until HOLD is
deactivated.
If there is a fault in the system or power supply
while HOLD is activated, the Brake immedi-
ately message appears in the multi-function Controls

Do
not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the war-
ranty.
Low outside temperatures The flow properties of diesel may be insuffi-
cient at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be
refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.
If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (e.g. in Mediterranean
regions) is available, you should add an
amount of flow improver to the fuel corre-
sponding to the outside temperature. Mix the additive with the diesel in good time,
before the flow properties of the diesel
become
insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel
engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor-
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehi-
cle is in motion. The bonnet could other-
wise open.
Opening G
Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become
very hot.
To
avoid the risk of burns, only touch those
components described in the Owner’s Man-
ual and observe the relevant safety notes. G
Risk of injury
The radiator fan between the radiator and
the engine can start automatically, even if
the
key has been removed from the ignition
lock. For this reason you must not reach
into the turning area of the fan. You could
otherwise sustain an injury.
