operation of the vehicle systems. This can
impair the operating safety of your vehicle
while driving. There is a risk of an accident.
Do not connect any equipment to the on-
board diagnostics connection. G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostics
connection can obstruct the area around the
pedals. The equipment or the cables could
come between the pedals in the event of
sudden braking or acceleration. This may
affect the function of the pedals. There is a
risk of an accident.
Do not attach any equipment or cables in the
driver's footwell.
! If the engine is switched off and
equipment on the diagnostics connection
is used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to
emissions monitoring information being
reset. This may lead to the vehicle failing to
meet the requirements of the next emissions
test during the main inspection. Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.

your vehicle. Their purpose is to alert you and
others to various dangers. Therefore, do not
remove any warning stickers unless the
sticker clearly states that you may do so.
If you remove any warning stickers, you or
others could fail to recognize certain dangers
and be injured.
When driving your vehicle observe the
following information:
R the safety notes in this manual
R the Technical Data section in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles Problems with your vehicle

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
R BAS ( Brake Assist System)
R ESP ®
(Electronic StabilityProgram)
R EBD ( electronic brakeforcedistribution)
R ADAPTIVE BRAKE Important safety notes
G
WARNING
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 54

flashes. ESP
®
only stabilizes the vehicle to a
limited degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is only restricted to a limited
degree, and the drive wheels are able to
spin. The spinning wheels produce a
cutting effect for better traction.
Characteristics when ESP ®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 0089warning lamp in the
instrument cluster does not flash. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction. EBD (electronic brake force
distribution)
Observe the "Important safety notes" section
(Y page 56).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. G
WARNING
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
Observe the "Important safety notes" section
(Y page 54).
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also features the hill start assist
function ( Ypage 115). For further
information, see Driving tips (Y page 131). Theft deterrent locking system
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
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.
X To activate with KEYLESS-GO: switch the
engine off and open the driver's door.
X To activate with the SmartKey: remove
the SmartKey from the ignition lock.
X To deactivate: switch on the ignition.
i The immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be
started when the starter battery is fully
charged, the immobilizer may be faulty.
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)
