Indication of a flat tireThe yellow warning lamp lights up. A
Check Control message is displayed.
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
normal tires or run-flat tires.
Run-flat tires, refer to page 214, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's 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.
Observe the information on run-flat tires and
continued driving with these tires.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits
A natural, even tire inflation pressure loss in all four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
Sudden serious tire damage caused by exter‐
nal circumstances cannot be recognized in ad‐
vance.
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: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.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.
The tire pressure gage of the Mobility Sys‐
tem, refer to page 215, can possibly 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 service
center or another qualified service center
or repair shop.2.Replace the damaged tire with the emer‐
gency wheel as needed or fix it where ap‐
plicable with the Mobility System.
Run-flat tires
Maximum speed
You may 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, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:

Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the follow‐
ing functions:
▷Front-end collision warning with City Brak‐
ing function, refer to page 116.▷Front-end collision warning with braking
function, refer to page 119Front-end collision warning
with City Braking function
The concept The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range
It responds to objects if they are detected by
the system.

InformationWARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem limits, warnings or reactions of the system
may not be output or they may be output too
late or incorrectly. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing

ing function. There is risk of an accident.

SymbolMeasureSymbol lights up red: prewarning.

signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with some braking intervention if there is risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Detection range
The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:▷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.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.Seite 118ControlsSafety118
