light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press 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 Press 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 selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed
Press button.
Or:
Press the rocker reel while the system is inter‐
rupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.

Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Tire age DOT … 4314: the tire was manufactured in the
43th week of 2014.
Recommendation
Regardless of wear and tear, 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 TreadwearTraction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral 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 signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
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 surfaces 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,
hydroplaning, 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.
Sustained high temperature can cause the ma‐
terial 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 passengerSeite 201Wheels and tiresMobility201

Information about the approved snow chains
are available from the service center.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷225/55 R 17.▷245/45 R 18.▷245/40 R 19.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing 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 needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.
