ESP
®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 54).
ETS traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
When ESP ®
is deactivated, the åESP®
OFF
warning lamp lights up continuously.
When SPORT handling mode is activated, the
M warning lamp lights up in the instrument
cluster.
When the åandh warning lamps light up
continuously, ESP ®
is not available due to a mal-
function.
Observe the information on warning lamps
(Y page 197) and display messages which may
be shown in the instrument cluster
(Y page 172).
Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly. Characteristics of ESP
® General notes
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X when pulling away, only depress the acceler-
ator pedal as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its previ-
ously selected status. Example:if ESP®
was
deactivated before the engine was switched off,
ESP ®
remains deactivated when the engine is
switched on again.

ESP ®
is activated every time the engine is star-
ted, regardless of whether ESP ®
was deactiva-
ted before the engine was switched off. G
WARNING
If you deactivate ESP ®

WARNING
When SPORT handling mode is activated,
there is a greater risk of skidding and acci-
dents.

In the following situations, it may be better to
activate SPORT handling mode or deactivate
ESP ®
:
R when snow chains are used
R in deep snow
R on sand or gravel
R on closed roads when the vehicle's own over-
steering and understeering characteristics
are desired
Driving in SPORT handling mode or without
ESP ®
requires a highly qualified and experi-
enced driver.
Activate ESP ®
as soon as the situations descri-
bed above no longer apply. ESP ®
will otherwise
not be able to stabilise the vehicle if the vehicle
starts to skid or a wheel starts to spin.

EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
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 (Y page 197) as well as display
messages (Y page 174). 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 (Y page 104).Protection against theft

Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the outside, the double lock function is activated as stand-
ard. It is then not possible to open the doors
from inside the vehicle. You can deactivate the
double lock function by deactivating the interior
motion sensor (Y page 62). The doors can then
be opened from the inside after the vehicle has
been locked from the outside. The anti-theft
alarm system is triggered if the door is opened
from the inside. Switch off the alarm
(Y page 60).
All countries: G
WARNING
If children are left unsupervised in the vehicle, they can:
R open doors and endanger other persons or
road users
R climb out and be injured by the traffic
R operate vehicle equipment and, for exam-
ple, trap themselves.
Children could also set the vehicle in motion, for example by:
R releasing the parking brake
R shifting the automatic transmission out of
park position P
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave children unattended in the vehicle. Always
keep the key out of reach of children.
G
WARNING
If you attach heavy or large objects to the key, the key could be unintentionally turned in the
ignition lock. This could cause the engine to
be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key into the ignition lock.
! Keep the key away from strong magnetic
fields. Otherwise, the remote control function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the key: R with electronic devices, e.g. a mobile phone
or another key
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can impair the key's function.
Vehicles with KEYLESS-GO start function: do
not keep the key on the luggage compartment
cover or in the luggage compartment. Other-
wise, the key may not be detected, e.g. when
starting the engine using the Start/Stop button.
A check that periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in or in the
direct vicinity of the vehicle. This occurs, for
example:
R during engine start
R during driving
R when using HANDS-FREE ACCESS
R when the external door handles are touched
R during convenience closing Key
