Make sure the seat belt retracts
completely. Otherwise the seat belt and/or
latch plate could get caught or pinched in
the door or in the seat mechanism. This can
damage the seat belt and impair its
effectiveness, and/or cause damage to the
door and/or door trim panel. Such damage
is not covered by the Mercedes-Benz
Limited Warranty.
Damaged seat belts must be replaced.
Contact an authorized Mercedes-Benz
Center.
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale 7 will always illuminate for
6 seconds to remind you and your passenger
to fasten your seat belts.
If the driver’s seat belt is not fastened when
the engine is started, an additional warning
chime will sound. The warning chime goes out
after approximately 6 seconds or once the
driver’s seat belt is fastened.
If after these 6 seconds the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) is not fastened with both
doors closed,
R the seat belt telltale 7 remains
illuminated for as long as either the driver’s
or passenger’s seat belt is not fastened.
R and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a
maximum of 60 seconds or until the
driver’s and passenger’s seat belt are
fastened.
If you and/or your passenger release the
seat belt during driving, the seat belt
telltale 7 starts flashing and the
warning chime sounds as described before.
If the driver’s or the passenger’s seat belt
remains unfastened after 60 seconds, the
warning chime stops sounding, the seat
belt telltale 7 stops flashing but
continues to be illuminated.
After a vehicle standstill, the warning chime
is reactivated and the seat belt telltale
7 is flashing again if the vehicle speed
once exceeds 15 mph (25 km/h).
The seat belt telltale 7 will only go out if
both the driver’s and the passenger’s seat
belt (with the passenger seat occupied) are
fastened, or the vehicle is standing still and a
door is opened.
For more information, see “Practical hints”
( Y page 35).
Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts are equipped with ETDs and
seat belt force limiters.
The ETDs are designed to activate in the
following cases:
R in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R in side impacts exceeding the system’s
preset deployment threshold on the far
side of the impact
R in certain vehicle rollovers
R if the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” ( Y page 44)
The ETDs will only activate if the seat belts are
fastened (latch plate properly inserted into
buckle).
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit

Driving safety systems
Introduction
This section contains information about the
following driving safety systems:
R ABS ( Antilock Brake System)
R Adaptive Brake
R BAS ( Brake Assist System)
R EBP ( Electronic Brake Proportioning)
R ESC ( Electronic Stability Control)
R Trunk Wing
Safety notes
GWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance from other road users
and objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
i In winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
ABS
GObserve Safety notes, see page 61.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
XKeep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
Driving safety systems61Safety and securityBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 61Z

functions as a reminder to take extra care
while driving.
Emergency brake maneuverXKeep continuous full pressure on the brake
pedal.GWarning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
BAS
GObserve Safety notes, see page 61.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
GWarning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
ESC
GObserve Safety notes, see page 61.
The Electronic Stability Control (ESC) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESC recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESC works to stabilize the vehicle. The ESC is
especially useful while driving off and on wet
or slippery road surfaces. The ESC also
stabilizes the vehicle during braking and
steering maneuvers.
The ESC warning lamp ÷ in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is
running.GWarning!
Never switch off the ESC when you see the
ESC warning lamp ÷ flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESC cannot
prevent accidents resulting from excessive
speed.
! Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0 or 1, or SmartKey in starter switch
position 0 or 1) when the electronic parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with the rear axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.

! The ESC will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i The cruise control switches off
automatically when the ESC engages.
Electronic Traction System (ETS) GObserve Safety notes, see page 61.
The ETS (Electronic Traction System) is a
component of the ESC. The ETS improves the
vehicle’s ability to utilize available traction,
especially under slippery road conditions by
applying the brakes to a spinning wheel.
When you switch off the ESC, the ETS is still
enabled.
Switching ESC SPORT on or off
GWarning!
ESC SPORT should not be switched on during
normal driving.
Switching ESC SPORT on will result in the
following:
R no restriction to engine torque
R system-supported traction control is
limited
ESC SPORT is designed for driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch on ESC SPORT.
Do not switch on ESC SPORT when a spare
wheel is mounted.
To improve the vehicle’s traction, switch on
ESC SPORT. This allows the drive wheels to
spin and thus cut into surfaces for better grip,
for example
R when driving with snow chains
R in deep snow
R in sand or gravelGWarning!
Switch off ESC SPORT and switch on the ESC
immediately if the aforementioned
circumstances do not apply anymore.
Otherwise ESC SPORT will only stabilize the
vehicle to a limited extent when it is starting
to skid or a wheel is spinning.
When you switch on ESC SPORT
R the ESC stabilizes the vehicle only to a
limited extent
R the engine output is limited, but only to the
extent that allows the drive wheels to spin
and thus cut into surfaces for better grip
R the ETS will still apply the brakes to a
spinning wheel
R the ESC continues to operate when you are
braking hard
R the cruise control cannot be activated
R the cruise control switches off if activated
i When ESC SPORT is switched on and one
or more drive wheels are spinning, the ESC
warning lamp ÷ in the instrument
cluster flashes. However, the ESC will then
stabilize the vehicle only to a limited extent.

GWarning!
The ESC should not be switched off during
normal driving.
Disabling of the system will result in the
following:
Rno restriction to engine torque
Rloss of system-supported traction control
“ESC OFF” is designed for driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch off the ESC.
To improve the vehicle’s traction, switch off
the ESC. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
Rwhen driving with snow chains
Rin deep snow
Rin sand or gravel
GWarning!

warning lamp å in the instrument
cluster comes on.
The message ESC-OFF appears in the
multifunction display.
GWarning!
When the ESC OFF warning lamp å is on,
the ESC is switched off.
When the ESC warning lamp ÷ and the
ESC OFF warning lamp å are on
continuously, the ESC is not operational due
to a malfunction.
When the ESC is switched off or not
operational, vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESC.
! Avoid spinning of a drive wheel for an
extended period with the ESC switched off.
This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
XSwitching on: With the engine running,
press ESC switch : briefly.
The ESC OFF warning lamp å in the
instrument cluster goes out. The message
ESC-ON appears in the multifunction
display.
EBP
GObserve Safety notes, see page 61.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.
GWarning!
If the EBD malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addition, Adaptive Brake provides the hill-
start assist system (Y page 293).
For more information on the brake system,
see (Y page 349).
Trunk Wing
GObserve Safety notes, see page 61.
The Trunk Wing enhances the vehicle’s
driving stability. It adapts the aerodynamics
of the vehicle to the driving conditions
according to the speed.
Trunk Wing switch : should be used for
cleaning only, see “Trunk Wing”
(Y page 360). It is not needed for Trunk Wing
operation.
The Trunk Wing extends at a vehicle speed of
above 75 mph (120 km/h) automatically.
Trunk Wing switch : flashes for as long as
the Trunk Wing extends. It remains
illuminated in red when the Trunk Wing is fully
extended.
Driving safety systems65Safety and securityBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 65Z

The Trunk Wing remains extended as long as
the vehicle speed is above 50 mph
(80 km/h).
Once the vehicle speed is below 50 mph
(80 km/h), the Trunk Wing retracts
automatically. Trunk Wing switch : flashes
for as long as the Trunk Wing retracts. It goes
out when the Trunk Wing is fully retracted.
Anti-theft systems
Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
Activating
XWith KEYLESS-GO: Turn off the engine and
open the driver’s door.
XWith SmartKey: Remove the SmartKey
from the starter switch.
Deactivating
XSwitch on the ignition.
iStarting the engine will also deactivate
the immobilizer.
In the event that the engine cannot be
started (yet the vehicle’s battery is
charged), the system is not operational.
Contact an authorized Mercedes-Benz
Center or call 1-800-FOR-MERCedes (in the
USA) or 1-800-387-0100 (in Canada).
Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
Ra door
Rthe trunk
Rthe hood
The alarm will stay on even if the activating
element, a door, for example, is closed
immediately.
The alarm system will also be triggered when
Rthe vehicle is opened with the mechanical
key
Ra door is opened from the inside
Rthe trunk is opened with the emergency
release button
To cancel the alarm after it has been
triggered, see “Canceling the alarm”
(Y page 67).
iIf the alarm stays on for more than
30 seconds, the mbrace system initiates a
call to the Customer Assistance Center
automatically. The mbrace system will
initiate the call provided that
Ryou have subscribed to the mbrace
service
Rthe mbrace service has been activated

Safety InstructionsGWarning
For safety reasons, only enter a destination
when the vehicle is stationary. When the
vehicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
COMAND calculates the route to the
destination without taking account of the
following:
R Traffic lights
R Stop and right-of-way-signs
R Lane merging
R Parking or stopping prohibited areas
R Other road and traffic rules and regulations
R Narrow bridges
GWarning
COMAND may give incorrect navigation
commands if the data in the digital map does
not correspond with the actual road/traffic
situation. Digital maps do not cover all areas
nor all routes within an area. For example, if
the traffic routing has been changed or the
direction of a one-way road has been
reversed.
For this reason, you must always observe
applicable road and traffic rules and
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system.
GWarning
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your
attention from driving and increase your risk
of an accident.
Updating the Map Software
The digital data for the map software will
become obsolete, just like conventional road
maps. Optimum route guidance by the
navigation system is only achieved with up-
to-date map software. Information on new
map software versions is available from an
authorized Mercedes-Benz Center.
You can have the map software updated there
by means of a DVD or perform the update
process yourself.
Notes on DVD Discs
R Only touch the discs at the edges.
R Handle the discs with care in order to
prevent reading errors.
R Avoid scratching, leaving fingerprints and
dust on the discs.
R Use a commercially available cleaning cloth
to clean discs. Always wipe in a straight line
from the inside outwards, never in a circular
motion.
R After use, put the discs back into the box.
R Protect the discs from heat and direct
sunlight.
Update Sequence
The sequence includes the following stages:
R Loading DVD into the DVD changer
R Update process
i The update process may take between 60
and 150 minutes, depending on the size of
the map software.
If possible, perform the update when the
vehicle is stationary. The DVD read speed
is faster when the vehicle is stationary than
when the vehicle is moving and the update
therefore takes less time. If you perform
the update with the engine off and the
