Introduction

The following text is published as required of
manufacturers under Title 49, Code of U.S. Fed-
eral Regulations, Part 575 pursuant to the
"National Traffic and Motor Vehicle Safety Act of
1966".
If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA) in addition to notifying Mercedes-Benz USA, LLC.
If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order
a recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz
USA, LLC.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go tohttp://
www.safercar.gov; or write to: Administrator,
NHTSA, 400 Seventh Street, SW., Washington,
DC 20590.
You can also obtain other information about
motor vehicle safety at:

Limited Warranty
!
Observe the notes in this Operator's Manual
regarding the correct operation of your vehi-
cle and possible damage to the vehicle. Dam-
age to the vehicle which is caused by violation
of these notes is not covered by the
Mercedes-Benz implied warranty or the new
or used-vehicle warranty.
QR code for rescue card
The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident, rescue services can use
the QR code to quickly find the appropriate res- cue card for your vehicle. The current rescue
card contains the most important information
about your vehicle in a compact form, e.g. the
routing of the electric cables.
You can find more information under
www.mercedes-benz.de/qr-code.
Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are necessary for
your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made
possible by electronic control units.
Electronic control units contain data storage
systems that can temporarily or permanently
save technical information concerning the vehi-
cle's condition, component stress and mainte-
nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, for example:
Roperating states of system components (e.g.
fill levels, battery status, tire pressure)
Rstatus messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi-
cation of whether seat belts are fastened)
Rmalfunctions and defects in important system
components (e.g. lights, brakes)
Rinformation about events leading to vehicle
damage
Rsystem responses in special driving situations
(e.g. air bag deployment, intervention of sta-
bility control systems)
Rambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit function, these data are used by manufacturers
to detect and rectify malfunctions and to opti-
mize vehicle functions. Most of these data are
volatile and processed only in the vehicle itself.
Only a small part of the data is stored in event or malfunction memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees or third parties. Services can include
repair services, maintenance processes, war-
ranty cases and quality assurance measures.
The data is read out via the legally prescribed
diagnostics connection in the vehicle. The rele-
vant offices in the service network or third par-
ties collect, process and use the data. These
data document the vehicle's technical states,

The spinning of the wheels results in a cut for
better traction on loose surfaces.

RPRE-SAFE®is unavailable

EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 57).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 196) as well as display
messages (Ypage 172).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also fea-
tures the hill start assist function (
Ypage 107).
Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
XTo activate with KEYLESS-GO start-func-
tion or KEYLESS-GO: switch the ignition off
and open the driver's door.
XTo activate with the SmartKey: remove the
SmartKey from the ignition lock.
XTo deactivate: switch on the ignition.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Anyone
can start the engine if a valid SmartKey has been
left inside the vehicle.
iThe immobilizer is always deactivated when
you start the engine.
In the event that the engine cannot be started
(yet the vehicle's battery is charged), the sys-
tem 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).
ATA (anti-theft alarm system)
XTo arm: lock the vehicle with the SmartKey or
KEYLESS-GO.
Indicator lamp :flashes. The alarm system
is armed after approximately 15 seconds.
XTo disarm: unlock the vehicle with the Smart-
Key or KEYLESS-GO.
or
XWith KEYLESS-GO start function or vehi-
cles with KEYLESS-GO: press the Start/
Stop button.

When the locator lighting is activated via the
multimedia system, it lights up when it is dark
after the vehicle is unlocked with the SmartKey.
Information on activating and deactivating the
locator lighting can be found in the Digital Oper-
ator's Manual.
XTo open the tailgate:press and hold the
F button until the tailgate opens.
KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a Smart-
Key in the vehicle (
Ypage 107).
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the
SmartKey with you. You can combine the func-
tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
& button on the SmartKey.
The driver's door and the door at which the han-
dle is used, must both be closed. The SmartKey
must be outside the vehicle. When locking or
unlocking with KEYLESS-GO, the distance
between the SmartKey and the corresponding
door handle must not be greater than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen using the tailgate unlocking sensor
Rwhen the external door handles are touched
Rduring convenience closing
XTo unlock the vehicle: touch the inner sur-
face of the door handle.
XTo lock the vehicle: touch sensor surface :
or ;.
Make sure that you do not touch the inner
surface of the door handle.
XConvenience closing feature: touch
recessed sensor surface ;for an extended
period.
Further information on the convenience clos-
ing feature (
Ypage 77).
Deactivating and activating
If you do not intend to use the vehicle for a lon-
ger period of time, you can deactivate KEYLESS-
GO. The SmartKey will then use very little power,
thereby conserving battery power. For the pur-
poses of activation/deactivation, the vehicle
must not be nearby.
XTo deactivate: press the&button on the
SmartKey twice in rapid succession.
The indicator light on the SmartKey flashes
twice briefly then one long flash, then KEY-
LESS-GO is deactivated (
Ypage 68).
XTo activate: press any button on the Smart-
Key.
or
XInsert the SmartKey into the ignition lock.
KEYLESS-GO and all of its associated features
are available again.
KEYLESS-GO start function
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a Smart-
Key in the vehicle (
Ypage 107).
