or in the immediate vicinity of the wheel
arches when the vehicle is being lowered.
GWARNING
Vehicles with level control:
The vehicle is slightly lowered if:
Ryou have selected comfort suspension
tuning and
Ryou lock the vehicle within approximately
60 seconds of switching off the engine
You and people in the vicinity of the wheel
arch or the underbody may thus become
trapped. There isarisk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you lock
the vehicle.
!The vehicle is lowered by about 15 mm if:
Ryou have selected "Comfort tuning"
Ryou switch off the engine and then
Ryou lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
If you lock the vehicle within 60 seconds of
switching the engine off, it lowers slightly to
the selected Comfort suspension mode.
Your vehicle regulates its height
automatically.All-round level control ensures
the best possible suspension and constant
groundclearance, even withaladen vehicle.
When you drive fast,the vehicle is lowered
automatically to improve drivingsafetyand to
reducefuel consumption.
The followingvehicle levels are possible:
Rnormal
Rraised: the vehicle is raised by about
0.80 in (20 mm) when compared with the
normal level
Rlowered: the vehicle is raised by about
0.40 in (10 mm) when compared with the
normal level
iThese changes in level are so slight that
you are hardly aware of them.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set
automatically:
Rat speeds above 70 mph (113km/h)

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.

Driving and parking

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

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.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
