which is not of an equivalent quality could
affect your vehicle's operating safety.
High-performance and ceramic brake
system (Mercedes-AMG vehicles)
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
RSpeed
RBraking force
RAmbient conditions, e.g. temperature and
humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain more informa-
tion on this from a qualified specialist work-
shop.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal. Keep this in mind, and adapt
your driving and braking accordingly during
this break-in period.
Excessive heavy braking results in corre-
spondingly high brake wear. Observe the
brake system warning lamp in the instrument cluster and note any brake status messages
in the multifunction display. Especially for
high performance driving, it is important to
maintain and have the brake system checked
regularly.
Checking brake lining thickness
You can measure the break pad/lining thick-ness using a test gauge. Color-coding (green
or red) on the test gauge allows you to deter-
mine whether the brake pad/lining thickness
is still sufficient. The test gauge is in the vehi- cle document wallet in the glove box.

178Driving tips
Driving and parking
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the park-
ing space as possible.
RParking spaces that are littered or over-
grown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(
Ypage 200) warning messages during the
parking procedure.
RYou can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Parking
Important safety notes
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 calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early.
GWARNING
If there are objects above the detection range, Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
GWARNING
Active Parking Assist merely aids you by inter- vening actively in the steering. If you do not
brake there is a risk of an accident.
Always apply the brakes yourself when
maneuvering and parking.
Detecting parking spaces
Example: detected parking space
Active Parking Assist is switched on automat-ically when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
When driving at speeds below 19 mph
(30 km/h) you will see parking symbol ;as
a status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right =or the left :also
appears.
By default, Active Parking Assist only displays
parking spaces on the front-passenger side.
Parking spaces on the driver's side are dis-
played as soon as the turn signal on the driv-
er's side is activated. If you wish to park in a

the driver's side must remain on. The turn
signal must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing theabutton on the multi-
function steering wheel.
Active Parking Assist will only detect parking
spaces:
Rthat are parallel to the direction of travel
Rthat are at least 59 in (1.5 m) wide
Rthat are at least 40 in (1.0 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it.
