AMG button. The vehicle also lowers if it is
stationary.
! If Sport or Sport + suspension tuning has
been selected, the vehicle's ground clear-
ance decreases. Make sure that no objects
become trapped or that the vehicle has not
been damaged, for example, on the kerb.
i The vehicle level may change visibly at the
rear axle if you park the vehicle and the
outside temperature changes. If the tem-
perature drops, the vehicle level lowers;
with an increase in temperature, the vehi-
cle level rises.
Changing the rear axle ride height
This function is only available for the CLS 63
AMG 4MATIC and CLS 63 AMG Shooting
Brake.
The vehicle level at the rear axle depends on
the selected suspension tuning and the vehi-
cle speed.
The vehicle level at the rear axle changes dur-
ing the journey depending on the selected
suspension tuning:
R
Comfort: +10 mm
R
Sport + and Sport: -15 mm
When switching from Comfort to Sport or
Sport +, the rear axle lowers by approximately
25 mm. When switching from Sport or Sport +
to Comfort, the rear axle raises by approx-
imately 25 mm. This level change also takes
place when the vehicle is stationary.
If you drive faster than 170 km/h, the rear
axle ride height is set to a medium level. This
increases driving safety and reduces air
resistance. If you then drive at speeds below
150 km/h, the rear axle ride height is read-
justed to the selected suspension tuning.
Load compensation
The vehicle can compensate differences in
the vehicle level by raising or lowering the
rear axle. This is the case, for example, if peo-
ple get out or if luggage is being loaded.
Load compensation takes place if:
R
a door or the boot lid/tailgate is opened
R
the parked vehicle is unlocked
For larger level changes, the engine must be
running.
4MATIC (permanent all-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 con-
ditions. 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 the lane.
If a drive wheel spins due to insufficient grip:
R
when pulling away, only depress the accel-
erator pedal as far as is necessary
R
accelerate less when driving
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP
® , it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
