Switching on/off and interrupting
cruise control
Switching on Press the button on the steering wheel.
The indicator lamps in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switching off Deactivated or interrupted system

actively intervene by braking and, if necessary,
with evasive maneuvers; otherwise, there is the
danger of an accident occurring.◀
If switching off the system while stationary,
press on the brake pedal at the same time.
Press the button on the steering wheel.
▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.
Interrupting the system
Press the button on the steering wheel.
If interrupting the system while stationary, press
on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:▷When the brakes are applied.▷When the clutch pedal is depressed.▷When transmission position D is disen‐
gaged.▷When DTC Dynamic Traction Control is ac‐
tivated or DSC is deactivated.▷When DSC is actively controlling stability.▷If the safety belt and the driver's door are
opened when the vehicle is standing still.▷If the system has not detected objects for an
extended period, e.g., on a road with very lit‐
tle traffic without road edge line markings.▷If the radar sensor is dirty.
Maintaining/storing the speed
Press the button.
Or:
Press the rocker switch while the system is in‐
terrupted.

When the system is switched on, the current
speed is maintained and stored as the desired
speed.
It is displayed in the speedometer and briefly
displayed in the instrument cluster, Displays in
the speedometer, refer to page 134.
When cruise control is maintained or stored,
DSC Dynamic Stability Control is switched on, if
necessary.
Changing/maintaining speed
The rocker switch can be pressed while the sys‐
tem is interrupted in order to maintain and store
the current speed.
Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; other‐
wise, there is the danger of an accident occur‐
ring.◀
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed if the road is
clear.
▷Each time the rocker switch is pressed to the
point of resistance, the desired speed in‐
creases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker switch is pressed past
the point of resistance, the desired speed

celerates the vehicle without requiring pres‐
sure on the accelerator. After the rocker
switch is released, the vehicle maintains its
final speed. Pressing the switch beyond theSeite 133Driving comfortControls133

xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
3510: tire age
Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
Tire age
DOT … 3510: the tire was manufactured in the
35th week in 2010.
Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Federal
Safety Requirements in addition to these
grades.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded
150 would wear one and one-half, 1 g, times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and may depart significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces of asphalt and concrete. A tire marked C may
have poor traction performance.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydro‐
planing, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus‐
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades Band A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or in
combination, can cause heat buildup and pos‐
sible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 202, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.Seite 199Wheels and tiresMobility199

Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains.
Snow chain detection
The concept
When using snow chains, you should set
whether you are driving with or without snow
chains via the iDrive.
The snow chain detection system supports you
by automatically showing the detected state on
the Control Display.
When snow chains are in use, the rear axle steer‐
ing of the Integral Active Steering is deactivated
automatically.
At speeds above the maximum permitted speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
Activating the status
1."Settings"2."Tire chains"3."Tire chains installed"Automatic detection
If functioning properly:▷Snow chains are mounted. The setting is not
activated
.
After you drive a short distance, a Check
Control message is shown and the state is
activated automatically.
Confirm the automatic activation.
▷Snow chains are not mounted. The setting
is activated

At speeds above 30 mph/50 km/h, a Check
Control message is displayed. Deactivate
the status manually.
If not functioning properly:

The automatic detection system is malfunc‐
tioning. Activate the status manually.
Activating/deactivating rear axle
steering
If the status indicating that snow chains are in
use is activated, the rear axle steering is deacti‐
vated automatically.
At speeds above 30 mph/50 km/h, the rear axle
steering is activated again, even though snow
chains are in use.
