Electric parking brake
General notes G
WARNING
If you leave children unattended in the vehi-
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 automatic transmission to position
P.
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. Applying or releasing manually X

High-performance and ceramic brakes
(Mercedes-AMG vehicles) The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
is dependent on:
R speed
R braking force
R environmental conditions, such as tempera-
ture and humidity
The wear of individual brake system compo-
nents such as the brake pads/linings or brake
discs depends on individual driving style and
operating conditions.
For this reason, it is impossible to state a mile-
age (service life) that will be valid under all cir-
cumstances. An aggressive driving style will
lead to high wear. You can obtain more infor-
mation on this from a qualified specialist work-
shop.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after several hundred kilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Always be aware of this and adapt your
driving and braking accordingly during the run-
ning-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. If you regularly drive at high speeds, it is particularly important to have the brake system
checked and maintained regularly. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth on
the road surface, there is a danger of aquaplan-
ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in
the event of heavy rain or in conditions in which aquaplaning can occur:
R lower your speed
R avoid tyre ruts R
avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may cause the maximum permissible water
depth to be exceeded.
These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the vehicle body
R you should drive no faster than walking pace Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter. 166

Important safety notes i
RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
i RACE START is only available in
Mercedes‑ AMG vehicles.
RACE START enables optimum acceleration
from a standing start. For this, a suitably high- grip road surface is required; the tyres and vehi-
cle must also be in good condition. G
WARNING
If you use RACE START, individual tyres may
get into a spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.

Parking tips:
R On narrow roads, drive as closely as possible
past the parking space
R Parking spaces that are littered or overgrown
might be identified or measured incorrectly
R Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately
R Pay attention to the PARKTRONIC
(Y page 186) warning messages during the
parking procedure
R You can intervene in the steering procedure
to correct it at any time. Active Parking Assist
is then deactivated
R When transporting a load that protrudes from
your vehicle, you should not use Active Park-
ing Assist
R Never use Active Parking Assist when snow
chains are fitted
R Always pay attention to the specified tyre
pressure for your vehicle. This has a direct
influence on the parking characteristics of the vehicle
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Objects located above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken into account when the parking procedure is cal-culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident. If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
Further information on the detection range
(Y page 185).
Active Parking Assist does not assist you with
parking in spaces at right angles to the direction of travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park
Active Parking Assist does not assist you with
parking in spaces that are parallel or at right
angles to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer :

no longer work properly in such cases.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext to =and behind :your vehicle, as
shown in the picture.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time Warning lamp

Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
