2017 MERCEDES-BENZ S-Class COUPE towing

Comfort tuning
In comfort mode, the driving characteristics of
your vehicle are more comfortable. Therefore,
select this mode if you favor a more comfortable
driving style. Select comfort mode also when
driving fast on straight roads, e.g. on straight
stretches of highway.

Mercedes-AMG vehicles: theAMG Suspen‐
sion System COMFORTmessage appears in
the multifunction display.
All other models: theAIRMATIC COMFORT
message appears on the multifunction dis-
play.
If the driving speed is higher than 75 mph
(12 0km/ h), the vehicle is automatically low-
ered by another 0.4 in (10 mm) compared to the
normal level in comfort mode.
All vehicles except Mercedes-AMG vehicles:
if the driving speed is higher than 100 mph
(160 km/h) and "Comfort" mode is activated,
the vehicle is automatically lowered by 0.4 in
(20 mm).
Load compensation
The vehicle can compensate differences in the
vehicle level by raising or lowering the axles.
4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP®, it improves
the traction of your vehicle whenever a drive
wheel spins due to insufficient grip. 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.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate 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 Limited Warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
In 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.
PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distance between your vehicle and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. When maneuvering, parking or pulling
out of a parking space, make sure that there are
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 detect such objects when they are in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.

General notes
Apart from certain country-specific variations,
the vehicles are not equipped with a tire-change
tool kit. If your vehicle is equipped with a tire-
change tool kit, it is located in the stowage well
under the trunk floor. Some tools for changing a
wheel are specific to the vehicle. For more infor-
mation on which tire changing tools are required
and approved to perform a wheel change on
your vehicle, consult a qualified specialist work- shop.
Necessary tire-changing tools can include, for
example:
RJack
RWheel chock
RLug wrench
RRatchet wrench
RAlignment bolt
