The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driv‐
er's side when the vehicle is at a standstill.
When driving in reverse, only the turning lamp
is active.
Self-leveling headlamps The self-leveling headlamps compensate for
acceleration and braking operations in order
not to blind the oncoming traffic and to achieve
optimum illumination of the roadway.

Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on
the position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Con‐
trol Display.
Calibrating the front seats A corresponding message appears on the
Control Display.1.Move the respective seat forward all the
way.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disap‐
pears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury
or damage to objects.◀
Rollover protection system The concept
The rollover protection system is automatically
activated in the event of a sufficiently serious
accident or if the longitudinal axis is tilted ex‐
cessively. The safety frames located behind
the rear headrests extend within fractions of a
second.
Supplementing the reinforced front windshield
frame, the rollover protection system further
increases passenger safety.
Maintaining movement space
Always keep the movement space of the
rollover protection system clear. Otherwise,
there may be damage or injuries when the roll‐
over protection system is triggered.◀
Triggered rollover protection system After deployment or damage
After deployment of the rollover protec‐
tion system or in the event of damage, have
the system checked and replaced.
Have this work performed only by your service
center; otherwise, it cannot be ensured that
this safety feature will function properly.◀
Do not move convertible top
When the rollover protection system is
extended, do not move the convertible top.
Otherwise, damages or injuries may result.◀
If the rollover protection system was not
placed under any stress after an automatic
triggering, it can be pushed back by hand, e.g.
to close the convertible top. Three people are
necessary for this.1.Push the lever to the side and hold it in this
position.2.Push down the safety frame.3.Release lever.4.Hold down the safety frame.Seite 99SafetyControls99

5.Proceed likewise with the second safety
frame.6.Close the convertible top
In the event of malfunctions, deactivation
or after deployment
Only have the airbags checked, repaired or dis‐
mantled and the system scrapped by your
service center. Non-professional attempts to
service the system could lead to failure in an
emergency or undesired triggering of the air‐
bag, either of which could result in injury.◀
Malfunction A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM
The concept The system monitors tire pressure in the four
mounted tires. The system warns you if there
is a significant loss of pressure in one or more
tires. For this purpose, sensors in the tire
valves measure the tire pressure and tire tem‐
perature.
Hints Tire damage due to external factors
Sudden tire damage caused by external
influences cannot be indicated in advance.◀
Pay attention to the other information and indi‐
cations under Tire inflation pressure, refer to
page 191, as well when using the system.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire pressure loss is not en‐
sured.
Reset the system again after each correction
of the tire inflation pressure and after every tire
or wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display
The current status of the Tire Pressure Moni‐
tor TPM can be displayed on the Control Dis‐
play, e.g., whether or not the TPM is active.1."Vehicle Info"2."Vehicle status"3. "Tire Pressure Monitor"
The status is displayed.
Status display The tire and system status is indicated by the

Check Control message is displayed.
▷There is a flat tire or a major loss in
tire inflation pressure.▷No reset was performed for the system.
The system therefore issues a warning
based on the tire pressures before the last
reset.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 201, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a low inflation pressure is indicated,
DSC Dynamic Stability Control is switched on
if necessary.
Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, it is possible that a reset was not
carried out for the Tire Pressure Monitor. In
that case, carry out a reset.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Use of tire sealant, e.g., the Mobility Sys‐
tem, may damage the TPM wheel elec‐
tronics. In this case, have the electronics
checked at the next opportunity and have
them replaced if necessary.
Run-flat tires
Maximum speed
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.Seite 101SafetyControls101
Online Edition for Part no. 01 40 2 910 721 - VI/13

If the tire inflation pressure in all four tires
is correct, it is possible that a reset was not
carried out for the Tire Pressure Monitor. In
that case, carry out a reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Required inflation pressure check
message
A Check Control message is displayed.
Check the tire inflation pressure and carry out
a reset of the system.
In some cases, a wheel was changed without
having carried out a reset.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported even though the tire inflation pres‐
sures are correct.
The tire pressure depends on the temperature
of the tire. If the tire temperature rises, e.g.,
due to driving or because of the heat of the
Sun, the tire inflation pressure increases also.
The tire pressure is reduced when the tire
temperature falls again. This behavior may
cause a warning to be issued if temperatures
fall very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure can be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Disturbance by systems or devices with
the same radio frequency: after leaving the
area of the disturbance, the system auto‐
matically becomes active again.Seite 102ControlsSafety102

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
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 indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.
FTM Flat Tire Monitor
The concept The system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐ tion of the tire inflation pressure and afterevery tire or wheel change.
Status display The current status of the Flat Tire Monitor canbe displayed on the Control Display, e.g.,
whether or not the FTM is active.1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.

Run-flat tires, refer to page 201, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.

Collision warning
Depending on how the equipment is equipped,
the collision warning system consists of one of
the two systems:▷Collision warning with City Braking func‐
tion, refer to page 108;▷Collision warning with braking function, re‐
fer to page 106
Collision warning with
braking function
The concept The system issues a warning if there is immi‐
nent danger of a collision and also includes a
braking function.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor in
conjunction with a camera.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. The time
of these warnings may vary depending on the
current driving situation.
Detection range
It responds to stationary or moving objects
that are within the detection range of the radar
system.
