Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys‐
tems being monitored.
A Check Control message consists of indicator
and warning lights in the instrument cluster
and, in some circumstances, an acoustic signal.
Indicator/warning lights
The indicator and warning lights can light up in
a variety of combinations and colors in display
area 1 or 2.
Several of the lights are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
The symbol indicates that Check Control
messages have been stored. The Check Control
messages can be displayed later.
What to do in case of a malfunction
The meaning of each light in the event of a
malfunction and tips on how to respond are
provided in the list, refer to page 194.

General information
When the driver's door is opened with the igni‐
tion switched off, the exterior lighting is auto‐
matically switched off when the light switch is
in position 0, 2, or 3.
Switch on the parking lights if necessary, switch
position 1.
Parking lights
Switch position 1: the vehicle lights light up on
all sides.
Do not use the parking lights for extended peri‐
ods; otherwise, the battery may become dis‐
charged and it would then be impossible to
start the engine.
When parking, it is preferable to switch on the
one-sided roadside parking lights, refer to
page 70.
Low beams Switch position 2: the low beams are lit when
the ignition is switched on.
Automatic headlight control
Switch position 3: the low beams are switched
on and off automatically depending on the am‐
bient light, e.g., in tunnels, in twilight, or if
there is precipitation. Adaptive Light Control is
active.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on independ‐
ent of the ambient lighting conditions when
you switch on the front fog lights.Seite 69LampsCONTROLS69

The exterior lighting goes out automatically af‐
ter the vehicle is switched off.
System limits
The automatic headlamp control cannot serve
as a substitute for your personal judgment of
lighting conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lights manually un‐
der these conditions.

Initialization is completed while the car is
traveling without feedback being given.Indication of a flat tire
The warning lights come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or a major loss in tire
inflation pressure.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 162, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Fol‐
low the information on run-flat tires and con‐
tinued driving with these tires. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the inflation pressure in
all four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 162, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If identification of flat tire damage is not
possible, please contact a dealer’s serviceSeite 78CONTROLSSafety78
Online Edition for Part no. 01 40 2 964 433 - VI/15
Performing a reset
Perform a system reset after adjusting the tire
inflation pressure to a new value and after
changing a tire or wheel.1.Start the engine, but do not start driving.2.Press the button on the turn indicator lever
repeatedly until "SET/INFO" is displayed.3.Press and hold the button until the display
changes.4.Press the button repeatedly until the sym‐
bol for the Tire Pressure Monitor and "AC‐
TIVE" are displayed. The Tire Pressure Mon‐
itor can be reset with "RESET".5.Press and hold the button until "RESET‐
TING" is displayed.6.Drive away.
After a short trip at over 20 mph/30 km/h,
the set tire inflation pressures are adopted
as target values. The reset is completed au‐
tomatically as you drive.
The trip can be interrupted at any time.
When driving resumes, the reset is contin‐
ued automatically.
Low tire pressure message
The warning lights come on in yellow
and red. A Check Control message is
displayed. In addition, a signal sounds.
▷There is a flat tire or substantial loss of infla‐
tion pressure on the indicated wheel.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 162, are la‐
beled on the tire sidewall with a circular
symbol containing the letters RSC.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
Seite 80CONTROLSSafety80
Online Edition for Part no. 01 40 2 964 433 - VI/15
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.Seite 83SafetyCONTROLS83

Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems.
When using the features and systems described
here, adhere to local regulations.
Antilock Brake System
ABS
ABS prevents locking of the wheels during braking.
Steerability is maintained even during full brak‐ ing. This increases active driving safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force distribution EBVThe system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
CBC Cornering Brake Control When braking in curves or during a lane
change, driving stability and steering response
are improved further.
Brake assistant
When the brakes are applied rapidly, this sys‐
tem automatically produces the maximum
braking force boost. In this way, the system
helps keep the braking distance as short aspossible. This system utilizes all of the benefits
provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of full braking.
Dynamic Stability Con‐
trol DSC
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 to the individual
wheels.
Adapt your driving style to the situation, for an
appropriate driving style is always the responsi‐
bility of the driver.
DSC is operational every time you start the en‐
gine.
WARNING
When driving with roof load, e.g. with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is risk of
accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC when
driving with roof load. ◀Seite 84CONTROLSDriving stability control systems84
Online Edition for Part no. 01 40 2 964 433 - VI/15
Deactivating DSC
Press the switch until the DSC OFF indicator
lamp lights up in the speedometer and DSC OFF
appears in the tachometer. DSC is deactivated.
Intervening measures to stabilize the vehicle
and give it forward momentum are no longer
executed.
When driving with snow chains or to rock the
vehicle free of snow, it may be useful to deacti‐
vate DSC temporarily.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the switch again; the DSC indicator lamps
in the display elements go out.
Indicator/warning lights The indicator lamp in the tachometer
flashes: DSC is controlling the drive
forces and brake forces.
The indicator lamp lights up: DSC and DTC has
failed.
The indicator lamp in the speedometer
lights up and DSC OFF appears in the
tachometer.
DSC and DTC deactivated.
Dynamic Traction Con‐
trol DTC
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces.▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground.▷When driving with snow chains.Seite 85Driving stability control systemsCONTROLS85
