Important safety notes G
WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
betwee nthe vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered. G
WARNING
The vehicle is lowered if:
R you have selected the Comfort or Sport
suspension tuning and
R lock the vehicle after switching off the
engine
Persons in the vicinity of the wheel arch or the
underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you switch
off the engine. !
The vehicle is lowered by approximately
10 mm if:
R you have selected the Sport or Comfort
suspension tuning and
R you switch off the engine and then
R lock the vehicle
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.
Vehicle level Level control adapts the vehicle level
automatically to the current operating and
driving situation. Level control ensures the
best possible suspension and constant
ground clearance, even with a laden vehicle.
This improves driving safety and fuel
consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system (Y
page 212).
Due to the sportier suspension settings
compared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
In Comfort and Sport driving modes, after
locking the vehicle it lowers to the Sport+
level. When locking the vehicle at the raised
level, the vehicle does not lower.
The settings will remain stored after you
switch off the engine. When starting the
engine, the selected setting, e.g. AMG
adaptive suspension system Comfort, is
restored.
i The vehicle level may change visibly if you
park the vehicle and the outside
temperature changes. If the temperature
drops, the vehicle level lowers; with an
increase in temperature, the vehicle level
rises. 216

Information on driving
If the vehicle is heavily loaded, chec kthe tire
pressures and correct them if necessary.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you
suspect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires 400

description under "Mounting a wheel"
(Y page 424). Rotating the wheels

WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed at a qualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mounting awheel" section
(Y page 424).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, the tires should then be rotated
every 3000 to 6000 miles (5000 to
10,000 km), or earlier if the tire wear requires
this. Do not change the direction of wheel
rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tire pressure and,
if necessary, restart the tire pressure loss
warning system or the tire pressure monitor. Changing
