WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING

cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
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 key with you and lock the vehicle. Never leave
children unattended in the vehicle.

The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or the system is malfunc-
tioning, it may not be possible to apply the
released parking brake. X If this is the case, park the vehicle only on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the transmission to position
j.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or if
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake carries out a function check at regular intervals when the engine is
switched off. Noises that occur are normal. Parking

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in cold weather, in stop-start traffic, on short jour-
neys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style

General notes The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort. The damping is adjusted individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection of SportorComfort
The suspension setting is adjusted using the
corresponding button on the centre console.
i The mode can also be set using the AMG
DYNAMIC SELECT controller (Y page 152).
If the ignition is switched off for less than four
hours, the previously selected drive program is
activated when the engine is next started. If the
ignition is switched off for more than four hours,
Comfort mode is activated when the engine is
next started.
Sport mode The firmer setting of the suspension tuning in
Sport
mode ensures even better contact with
the road. Select this mode when employing a
sporty driving style, e.g. on winding country
roads.

Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and an obsta- cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in the manoeuvring area while manoeu-
vring and parking in/leaving parking spaces.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a lorry or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction. Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. Parking Assist
PARKTRONIC measures the minimum detec-
tion range to an obstacle from the bumper,
not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you:
R switch on the ignition
R shift the transmission to position h,kor
i for vehicles with automatic transmission
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds.
Vehicles with a trailer tow hitch: Parking
Assist PARKTRONIC is deactivated for the rear
area when you establish the electrical connec-
tion between your vehicle and a trailer.
Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods vehicles :
Sensors on the front bumper, left-hand side
(example)
The sensors must be free of dirt, ice and slush.
Otherwise, they may not function correctly.
Clean the sensors regularly, taking care not to
scratch or damage them (Y page 311). Driving systems
