Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance may increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button ( Ypage 79). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
ESP ®
detects when a wheel spins or the vehi-
cle starts to skid. ESP ®
stabilises the vehicle
by targeted braking of individual wheels and
by limiting engine power. It assists you when
pulling away on wet or slippery roads. ESP ®
also stabilises the vehicle during braking.
When ESP ®
intervenes, the vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrument
cluster flashes, proceed as follows:
R only depress the accelerator pedal as far
as necessary when pulling away.
R adapt your driving style to suit the pre-
vailing road and weather conditions.
The vehicle could otherwise go into a skid.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot override
the laws of physics.
! The ignition must be switched off (key in
position 0or 1in the ignition lock), if: R
the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front
axle raised
Application of the brakes by ESP ®
could
otherwise destroy the brake system on the
front axle.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly. Steering assistant STEER CONTROL
The steering assistant STEER CONTROL helps
you by transmitting a noticeable steering
force to the steering wheel in the direction
required for vehicle stabilisation. This steer-
ing assistance is provided in particular if:
R both right wheels or both left wheels are on
a wet or slippery road surface when you
brake
R the vehicle starts to skid
You have control over the steering at all
times. G
Risk of accident
If there is an ESP ®
malfunction, you will not
receive any steering assistance from the Safety

When active parking assist is cancelled, you
must steer again yourself.
Trailer towing* For vehicles with a trailer coupling, the mini-
mum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use active parking assist.
Once the electrical connection is established
between your vehicle and the trailer, active
parking assist is no longer available. Park-
tronic is deactivated for the rear area. ECO start/stop function*
The ECO start/stop function automatically
switches off the engine as soon as you stop
the vehicle and restarts the engine as soon as
you prepare to pull away again. Each time the
engine is started using the key, the ECO
start/stop function is activated.

Troubleshooting
223Problem Possible cause/consequence Suggested solutions
The indicator lamp in the
F/
1 rear-window heating button
is flashing. The rear-window heat-
ing has switched itself off prema-
turely or cannot be switched on. The on-board voltage is too low,
because too many consumers are
switched on. X
Switch off consumers that are not required, e. g. reading lamp or
interior lighting.
Once the battery is sufficiently charged, the rear window heating
will switch back on automatically. Vehicles with automatic child
seat recognition on the front-
passenger seat:
The
5 PASSENGER AIRBAG
OFF warning lamp on the centre
console is lit. A special Mercedes-Benz child
seat with automatic child seat
recognition has been fitted to the
front-passenger seat. The front-
passenger airbag has therefore
been disabled as desired.
G
Risk of injury
There is no child seat fitted to the
front-passenger seat. The auto-
matic child seat recognition is
malfunctioning. X
Remove electronic equipment from the front-passenger seat, for
example
R
notebook
R mobile phone
R cards with transponders, e.g. ski passes or access passes
If the 5 PASSENGER AIRBAG OFF warning lamp is still lit:
X Visit a qualified specialist workshop. You have started the engine with
the key. The indicator lamp in the
ECO start/stop function* button
does not light up or goes out
again after a short time. You have deactivated the ECO
start/stop function*. X
Activate the ECO start/stop function* again. The ECO start/stop function*is
not available due to a fault. X
Visit a qualified specialist workshop. Practical advice
