Dynamic Damping Control
The concept The tuning of the suspension can be changed
with the system.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 124.
SPORT Consistently sporty tuning of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning of the shock absorbers formore comfort.
Servotronic
The concept The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel and/or comfortable steering is con‐
veyed.
Variable sport steeringThe variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.Seite 123Driving stability control systemsControls123

Tire treadSummer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Information Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle mal‐
functions:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. If tire dam‐
age is suspected while driving, immediately re‐
duce speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to
the nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed.◀
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. Do not re‐
pair damaged tires, but have them replaced.◀
Changing wheels and tires
Mounting Have mounting and wheel balancing carriedout by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.
