steered when the SmartKey is removed from
the starter switch.
Switching off the engine
Important safety notes
GWarning
Do not turn off the engine before the vehicle
has come to a complete stop. With the engine
not running, there is no power assistance for
the brake and steering systems. In this case,
it is important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle.
Vehicles with manual transmission
XShift to either first gear or reverse gear R.XTurn the SmartKey to position 0 in the
ignition lock and remove it.

Vehicles with automatic transmission
XApply the parking brake firmly.XShift the transmission to position P.
Using the SmartKey
XTurn the SmartKey to position 0 in the
ignition lock and remove it.
The immobilizer is activated.
i The SmartKey can only be removed if the
transmission is in position P.
Using KEYLESS-GO
XPress the Start/Stop button (Y page 132).
When the driver's door is closed, the Start/
Stop button is in position 1. When the
driver's door is opened, the Start/Stopbutton moves to position 0. This
corresponds to removing the SmartKey.
If you attempt to turn off the engine when the
selector lever is not in position P, a warning
signal sounds.
Observe the messages in the multifunction
display.
i In an emergency, you can turn off the
engine while the vehicle is in motion by
pressing and holding the Start/Stop button
for three seconds.
If you have started the engine with the Start/
Stop button and it cannot be switched off as
described:
Xremove the Start/Stop button from the
ignition lock.Xinsert the SmartKey into the ignition lock.
The engine stops. The ignition lock is in
position 0.
Parking brake
GWarning
Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to lock
up. You could lose control of the vehicle and
cause an accident. In addition, the vehicle's
brake lights do not light up when the parking
brake is engaged.
GWarning
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children could
release the parking brake and/or shift the
automatic transmission out of park position
P (manual transmission: shift into the neutral
position), either of which could result in an
accident and/or serious personal injury.

GWarning
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that safe
braking is substantially impaired. This could
result in an accident.
! Vehicles with 4MATIC: a function or
performance test may only be carried out
on a two-axle dynamometer. If you are
planning to have the vehicle tested on such
a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further
information first. Otherwise, the drive train
or the brake system may suffer damage.
! Vehicles with 4MATIC: as the ESP®
system operates automatically, the engine
and the ignition must be switched off
(SmartKey in position 0 or 1 in the ignition
lock or Start/Stop button in position 0 or
1 ) while the parking brake is being tested
on a brake dynamometer.
Braking maneuvers triggered automatically
by ESP ®
may seriously damage the brake
system.
! Vehicles with 4MATIC: as the ESP®
system operates automatically, the engine
and the ignition system must be switched
off (SmartKey in position 0 or 1 in the
ignition lock or Start/Stop button in
position 0 or 1) when:
R testing the parking brake on a brake
dynamometer.
R you intend to have the vehicle towed with
the front axle raised.
Braking maneuvers triggered automatically
by ESP ®
may seriously damage the brake
system.
If your brake system is only subjected to
moderate loads, you should regularly test
your brake system's function by forcefully
depressing the brake pedal when driving at
high speed. This will give the brake pads
better grip.
GWarning
Make sure that you do not endanger other
road users when you apply the brakes.
You can find a description of Brake Assist
(BAS) on ( Y page 62).
High-performance brake system for
AMG vehicles
The high-performance brake system is only
installed on the C 63 AMG.
GWarning
New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide optimum braking efficiency. Until that
time, you may need to use increased brake
pedal pressure while braking. Please be aware
of this and adjust your driving and braking
accordingly during this break-in period.
Excessive high-demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition
messages in the multifunction display.
Especially for high performance driving, it is
important to maintain and have the brake
system checked regularly.
The high-performance brake system is
designed for heavy loads. This may lead to
noise when braking. This will depend on:
R speed
R braking force
R environmental conditions, such as
temperature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.

GWarning!
The rear view camera is only an aid and may
display obstacles
R from a distorted perspective
R inaccurately
R may not display obstacles at all
The rear view camera does not relieve you of
the responsibility to be cautious. Take care
and pay careful attention. The rear view
camera may not show objects which are
R very close to the rear bumper
R under the rear bumper
R above the trunk handle
You are responsible for safety at all times and
must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of, and beside the vehicle. Otherwise
you could endanger yourself and/or others.
GWarning!
The rear view camera either will not function
or will not function to its full capability if
R the trunk lid is open
R it is raining very hard, snowing or foggy
R it is night or you are parking/maneuvering
your vehicle in an area where it is very dark
R the camera is exposed to a very bright white
light
R the immediate surroundings are
illuminated with fluorescent light (the
COMAND system display can flicker)
R there is a sudden change in temperature,
e.g. if you drive into a heated garage from
the cold (lens condensation)
R the camera lens is dirty or covered
R the rear of your vehicle is damaged
In this case, have the position and setting
of the camera checked by a qualified
specialist workshop. Mercedes-Benz
recommends that you contact a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering.
Activating the rear view cameraXMake sure that the SmartKey is in
position 2 in the ignition lock.XMake sure that the "rear view camera"
function is selected in COMAND (see the
separate operating instructions for
COMAND).XEngage reverse gear.

If the coolant temperature rises above
248 ‡(120 †), do not drive any further as
this could damage the engine.
Tachometer
The red band in the tachometer indicates the
engine's overrevving range.
! Do not drive in the overrevving range, as
this could damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
The outside temperature display is in the
multifunction display.
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Changes in the outside temperature are
displayed after a short delay.
