Launch Control
The concept
Launch Control enables optimum acceleration
on surfaces with good traction.
Component wear
Do not use Launch Control too often; oth‐
erwise, this may result in premature wear of
components due to the high stress placed on
the vehicle.◀
Activate Launch Control
Launch Control is available when the engine is
warmed up, that is, after uninterrupted driving of
at least 6 miles/10 km.1.Deactivate Dynamic Stability Control, refer
to page 107.2.Select Sequential mode with driving pro‐
gram 3.3.With the engine running, lightly apply the
brakes with the left foot.4.While the vehicle is stationary, press the se‐
lector lever forward and hold it.
A flag symbol appears in the instrument
cluster.5.Fully depress the accelerator pedal.

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at individual wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.Seite 106ControlsDriving stability control systems106

Activating DSCPress the button.
DSC OFF and the DSC OFF indicator lamp
go out.
Via M Drive1."Settings"2."M Drive 1" or"M Drive 2"3. Select the symbol.4."DSC OFF"
To open M Drive with the selected settings,
press the corresponding button on the steering
wheel:
▷▷
A message appears in the instrument cluster.
This message is confirmed by pressing the but‐
ton again.
Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
Hill Start Assistant
The Hill Start Assistant provides assistance with
starting off on a hill, Drive-off assistant, refer to
page 106.
Active M differential
The concept
The active M differential assures continuously
variable locking of the rear axle differential de‐
pending on the driving situation. This prevents
individual rear wheels from spinning even when
DSC is switched off and in M Dynamic Mode, so
that optimum traction is always assured in all
driving situations.
The driver is responsible adapting his or her
driving behavior to the situation.
Electronic Damper Control
EDC
The concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs
Setting options for calibrating the shock absorb‐
ers:▷"Comfort": comfort-oriented.▷"Sport": balanced out.▷"Sport Plus": consistently sporty.

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.Seite 243Wheels and tiresMobility243
Online Edition for Part no. 01 40 2 900 735 - 03 12 490

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.◀
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer 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 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 required
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 ob‐
jects lodged in the tread, and tread wear.
Notes
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-pro‐
file tires.
