Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There isarisk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinityofthe wheel
arches when the vehicle is being lowered.
The vehicle lowers when you press the button
for selecting the suspension tuning or the
AMG button.The vehicle also lowers if it is
stationary.
!If Sport or Sport+suspension tuning has
been selected, thevehicle's ground
clearance decreases. Makesure that no
objectsbecome trapped or that thevehicle
does notbecome damaged, for example,
on the curb.
iThe vehicle level may change visibly at the
rear axle if you park the vehicle and the
outside temperature changes.Ifthe
temperature drops, the vehicle level
lowers; with an increase in temperature,
the vehicle level rises.
Changing the rear axle ride height
This function is only available for the CLS 63
AMG 4MATIC.
The vehicle level at the rear axle depends on
the selected suspension tuning and the
vehicle speed.
The vehicle level at the rear axle changes
during the journey depending on the selected
suspension tuning:
RComfort: +0.4 in (+10 mm)
RSport+and Sport: -0.6in(-15 mm)
When switching from Comfort to Sport or
Sport +, the rear axle lowers by approximately
1.0 in (25 mm). When switching from Sport
or Sport+toComfort, the rear axle raises by
approximately 1.0 in (25 mm). This level
change also takes place when the vehicle is
stationary.
If you drive faster than 105 mph(170 km/h),
the rear axle ride height is set toamedium
level. Thisincreases driving safety and
reduces airresistance. If you then drive at
speeds below 93 mph (150 km/h), the rear
axle ride height is readjusted to the selected
suspension tuning.

Load compensation
The vehicle can compensatedifferences in
thevehicle level by raisingorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
Radoor or the trunk lid/tailgate is opened
Rthe parked vehicle is unlocked
For larger level changes, the engine must be
running.
4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front,for vehicle speed, for braking in good
time and for staying in your lane.
Ifadrive wheel spins due to insufficientgrip:
ROnly depress the accelerator pedalasfar
as necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehiclewith one axle
raised. This may damage the transfer case.
Damageofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remaineitheronthe ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires(M+S tires), with snow
chains if necessary.
4MATIC ensures that allfour wheels are
permanently driven. Together with ESP®,it
improves the traction of yourvehicle
wheneveradrive wheel spins due to
insufficient grip.
PARKTRONIC
Important safetynotes
PARKTRONIC is an electronic parkingaid with
ultrasonic sensors. It indicates visually and
audibly the distancebetween your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacementfor your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exitingaparkingspace. When
maneuvering, parkingorpulling out of a
parkingspace, make sure that thereare no
persons, animals or objects in the area in
which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detectsuch objects
when they are in theimmediatevicinity of
thevehicle. You could damagethe vehicle
or the objects.
The sensors may not detect snow and other
objectsthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck orapneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to positionD,RorN
Rrelease the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown 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 toaparking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 195) warning messages during the
parking procedure.
RYou can intervene in the steeringprocedure
to correctitatany time. Active Parking
Assist will then be canceled.
RWhen transportingaload 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
alwayscorrect. This hasadirectinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthatare paralleltothe direction of travel
Rthat are on straight roads, not bends
Rthat are on the same levelasthe road,e.g.
not on the pavement
Detectingparking spaces
Objects located above the height range of
Active Parking Assist willnot 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.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may causeacollision asaresult. There is
arisk of an accident.
