Radar sensor
A radar sensor is located in the front bumper
for detecting vehicles on the road ahead of the
vehicle.
A dirty or covered sensor may hinder the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.
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 marking in the speedometer is
set to the current speed.
Cruise control can be used.
Switching off Deactivated or interrupted system
If the system is deactivated or inter‐
rupted, actively intervene by braking, steering
and, if necessary, with evasive maneuvers; oth‐
erwise, there is the danger of an accident oc‐
curring.◀
If switching off the system while stationary,
press on the brake pedal at the same time.
Press the button.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.
Interrupting When active, press the button.
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 transmission position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated 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 little traffic without road edge line
markings.▷If the detection range of the radar is dis‐
rupted, for example, by dirt or heavy fog.
Maintaining/storing the speed

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
system is interrupted in order to maintain and
store the current speed.

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when transmission position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Transmis‐
sion position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as the brake or accelerator pedal is
depressed, the engine is automatically coupled
to the transmission again.
Hints Coasting is a component of the ECO PRO, re‐
fer to page 171, driving mode.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and
supports the fuel-conserving effect of coast‐
ing.
Safety mode
The function is not available if one of the fol‐
lowing conditions is satisfied.
▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are satisfied:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in transmission posi‐
tion D.▷Engine and transmission are at operating
temperature.
Display
Display in the instrument cluster The mark in the bar display be‐
low the tachometer is backlit in
blue and is located at the zero
point. The tachometer approxi‐
mately indicates idle speed.
The coasting point indicator is illuminated at
the zero point during coasting.
Indications on the Control Display
The Coasting driving condition is displayed in
EfficientDynamics Info while this driving mode
is active.

Tire Identification NumberDOT code: DOT xxxx xxx 1013
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
1013: tire age
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
Tire age DOT … 1013: the tire was manufactured in the
10th week 2013.
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 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 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 re‐
quired 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
possible tire failure.
If necessary, have the vehicle towed.◀Seite 185Wheels and tiresMobility185

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 necessary.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
