Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the opti‐
mal protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to
keep the danger of injury to your hands or
arms as low as possible if the airbag is trig‐
gered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not cover
with adhesive labels or coverings, and do
not attach holders such as for navigation in‐
struments and mobile phones.▷Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷Make sure that occupants keep their heads
away from the side airbag and do not rest
against the head airbag; otherwise, injuries
can occur if the airbags are triggered.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system.
This also applies to steering wheel covers,
the dashboard, the seats, the roof pillars
and the sides of the headliner. ◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered;
otherwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
the service center or a workshop that has the
necessary authorization for handling explo‐
sives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
undesired triggering of the airbag, either of
which could result in injury. ◀
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the airbag
system
When the ignition is switched on, thewarning lamp in the instrument cluster
lights up briefly and thereby indicates
the operational readiness of the entire airbag
system and the belt tensioner.

accepted as reference values. The resetting
process is completed automatically during driv‐
ing.
The trip can be interrupted at any time. If you
drive away again, the reset resumes automati‐
cally.
Low tire pressure message The yellow warning lamp lights up. A
Check Control message is displayed.
▷There is a flat tire or a major loss in
tire inflation pressure.▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire

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 nec‐
essary.
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.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 173, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire using the Mobility Sys‐
tem, refer to page 173.
Use of tire sealant, e.g., the Mobility Sys‐
tem, may damage the TPM wheel electron‐
ics. 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.
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 depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending 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 prop‐
erties. ◀
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. ◀
Message when the system was not
reset
A Check Control message is displayed.
The system has detected a wheel change, but
no reset was carried out
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and carry out a
reset of the system.
System limits The system does not function properly if a reset
has not been carried out, e.g., a flat tire is re‐
ported even though the tire inflation pressures
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 tem‐
perature 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, such as a
compact wheel, is mounted: have the serv‐
ice center check it if necessary.▷Malfunction: have the system checked by
your service center.Seite 76ControlsSafety76

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.

SymbolMeasureThe vehicle lights up red: prewarning.
Increase braking and distance.The vehicle flashes red and an acous‐
tic signal sounds: acute warning.
You are requested to intervene by
braking or making an evasive maneu‐
ver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During a warning, the maximum brak‐
ing force is used. A prerequisite for the brake
booster is a sufficiently fast and sufficiently
strong actuation of the brake pedal. In addi‐
tion, if there is a risk of collision, the system can
assist with a slight braking intervention. The in‐
tervention can bring a vehicle traveling at slow
speed to a complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on and
Dynamic Traction Control DTC is activated.
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively
moving the steering wheel.
Tow-starting and towing
When tow-starting and towing the vehi‐
cle, switch off the Intelligent Safety systems;
otherwise, improper behavior of the braking
function of individual systems could result in an
accident. ◀
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring. ◀
Detection range The system's detection capabilities are limited.
This may result in the warning not being issued
or being issued late.
For example, the following situations may not
be detected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.▷Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.▷If the camera in the mirror is dirty or ob‐
scured.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant dimming because of on‐
coming light, for example, from the sun low
in the sky.
Prewarning sensitivity
Depending on the set prewarning time, this
may result in increased false warnings.

Driving comfortVehicle 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 vehi‐
cle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Camera-based cruise con‐
trol, ACC
The concept
This system can be used to select a desired
speed that the vehicle will maintain automati‐
cally on clear roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
A camera on the interior rear view mirror is
used to detect vehicles driving ahead.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
As soon as the road is clear, it accelerates to the
desired speed.
The speed is also maintained on downhill gradi‐
ents, but may not be maintained on uphill
slopes if engine power is insufficient.
General information
Depending on the set drive mode, refer to
page 88, the characteristics of the cruise con‐
trol can change in certain areas.Hints
Personal responsibility
Even an active system does not release
the driver from personal responsibility for the
driving process, especially for lane tracking, adaptation of speed, distance and driving style
to the traffic conditions.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Monitor the driving process, the surrounding
area and what is occurring in traffic continu‐
ously and attentively and actively intervene as
required, e.g., by braking, steering or making
an evasive maneuver. ◀
Unfavorable weather conditions
Unfavorable weather conditions, e.g.,
rain, snowfall or slush, may result in worsened
detection of vehicles as well as short-term in‐
terruptions with already detected vehicles.
Drive attentively, and react to the current traffic
events. Intervene actively when necessary, e.g.,
by braking, steering or making an evasive ma‐
neuver, otherwise, there is danger of an acci‐
dent. ◀
