switched on. The lamp goes out when the
engine starts running.
Braking If ABS intervenes when braking, you will feel
a pulsating in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. BAS (Brake Assist System)
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if
the BAS driving safety system is malfunction-
ing, the 003Dwarning lamp lights up while the
engine is running (Y page 221).
BAS operates in emergency braking situa-
tions. If you depress the brake quickly, BAS
automatically increases the brake pressure,
thereby reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. EBD (electronic brake force distribu-
tion)
G
WARNING
If EBD has malfunctioned, the rear wheels can
still 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.
EBD monitors and controls the brake pres-
sure to the rear wheels. This enables EBD to
improve handling during braking.
Observe the information on warning and indi-
cator lamps (Y page 221). ESP
®
(Electronic Stability Program)
Observe the important safety guidelines for
the driving safety system (Y page 56). G
WARNING
If ESP ®
is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Only operate the vehicle briefly (maxi-
mum of 10 seconds) on a brake dynamom-
eter. The key must be turned to position 1
in the ignition lock during this time. You
could otherwise damage the drive train or
the brake system.
! Do not run the vehicle on a roller dyna-
mometer (e.g. for performance tests). If
you must operate the vehicle on a roller
dynamometer, please consult a qualified
specialist workshop in advance. You could
otherwise damage the drive train or the
brake system.
If ESP ®
is malfunctioning, the 0089warning
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 221).
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
If you select the drive program S+on a vehicle
with an AGILITY SELECT switch, ESP ®
only
stabilizes the vehicle to a limited degree. Driving safety systems

G
WARNING
Other road users may ignore or fail to hear the
warning tone of the reverse warning feature.
There is a risk of injury if you fail to ensure
that the area in which you are maneuvering is
clear.
Make sure that there are no persons or
objects in the area in which you are maneu-
vering. It may be necessary to enlist the help
of a second person when maneuvering.
The reverse warning feature is a system
designed to assist you in ensuring the safety
of other road users.
A warning signal sounds to alert other road
users when reverse gear is engaged. The vol-
ume of the warning tone can be reduced for
night-time driving.
X To reduce the volume of the warning
tone: engage reverse gear twice in quick
succession.
The warning tone is now quieter.
i The warning tone sounds at a normal vol-
ume by default. The volume of the warning
tone has to be reduced each time you
engage reverse gear if necessary. ECO Start on Euro 6 engines
Important safety notes G
WARNING
If ECO Start is activated, the engine can be
started unintentionally, e.g. by accidentally
depressing the clutch pedal. If work is being
carried out on the engine under these circum-
stances, there is a risk of injury from moving
engine parts.
Deactivate ECO Start before work is carried
out on the engine. G
WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off

WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking
brake when the vehicle is stationary. X
To apply the parking brake: pull brake
lever 0043up as far as the last possible
detent.
The 0066 warning lamp in the instrument
cluster lights up if the engine is running.
i On vehicles with a folding brake lever, you
can then press lever 0043down to the stop.
X To release the parking brake: on vehicles
with a folding brake lever, first pull brake
lever 0043up to the stop.
X Raise brake lever 0043slightly and press
release knob 0044.
X Guide brake lever 0043down to the stop.
The 0066 indicator lamp in the instrument
cluster goes out.
Exceptionally, if the service brake fails, the
parking brake can be used to brake the vehi-
cle in an emergency.
X Emergency braking: press and hold
release button 0044and carefully apply brake
lever 0043. Switching off the engine

WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of
an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
! If the coolant temperature is very high,
e.g. after driving on hilly roads, leave the
engine running at idle speed for about
two minutes before turning it off.
This allows the coolant temperature to
return to normal.
