the corresponding wheel changes. This will be
detected and reported as a flat tire.
The system does not measure the actual inflaj
tion pressure in the tires.
Functional
requirements
The system must have been initialized when
the tire inflation pressure was correct; otherj
wise, reliable flagging of a flat tire is not asj
sured. Initialize the system after each correcj tion of the tire inflation pressure and afterevery tire or wheel change.
Status
display
The current status of the Flat Tire Monitor can be displayed on the Control Display, for examjple, whether or not the FTM is active.1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
When initializing, the set tire inflation presj
sures serve as reference values in order to dej
tect a flat tire. Initialization is started by conj
firming the tire inflation pressures.
Do not initialize the system when driving with
snow chains.
On the Control Display:
1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine but do not drive off.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving, which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication
of
a
flat
tire
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.1.Reduce your speed and stop cautiously. Avoid sudden braking and steering maneujvers.2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 208, are laj
beled with a circular symbol containing the letters RSC marked on the tire's sidewall.
WARNING
A damaged regular tire with low or missj
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-
flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if
the vehicle is not equipped with run-flat tires.
Follow the information on run-flat tires and
continued driving with these tires.'

Actions
in
the
event
of
a
flat
tire
Normal
tires1.Identify the damaged tire.
Check the air pressure in all four tires, e.g., using the tire pressure gage of a tire repair
kit.
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 dealerss servicecenter or another qualified service center
or repair shop.2.Repair the flat tire, e.g., with a tire repair kit
or by changing the tire.
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 maneuj vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires atthe 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:
The possible driving distance with a flat tire
depends on cargo load, driving style and road
conditions.
A vehicle with an average load has a possible driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differj
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering maj
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance dej
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lonj
ger depending on the driving speed, road conj
ditions, external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are longer and the self-steering properties will
change. There is a risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.'

Safety
information
WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj
tem may not be output or they may be output
too late or incorrectly. There is a risk of an acj
cident. Adjust the driving style to the traffic conditions. Watch traffic closely and activelyintervene in the respective situations.'

The system sounds a warning before an immij
nent collision and actuates brakes independj
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 approach control warning is available even
if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the approach control warning and
braking are delayed in order to avoid false sysj
tem reactions.
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
Objects are responded to if they are detected
by the system.

Prewarning
This warning is issued, e.g., when there is the impending danger of a collision or the distanceto the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute
warning
with
braking
function
Acute warning is displayed in case of the immij nent danger of a collision when the vehicle apj
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking interj
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 brakj
ing force is used. Prerequisite for the brake
booster is sufficiently quick and hard stepping on the brake pedal. The system can assist with
some braking intervention if there is a risk of a

collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if vej
hicle stability has not been restricted, e.g., by deactivating the DSC Dynamic Stability Conj
trol.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by acj
tively moving the steering wheel.
Object detection can be restricted. Observe
the limitations of the detection range and funcj tional restrictions.

Under those circumstances it reacts to peoplewho are within the detection range of the sysj
tem.
Detection
range
The detection area in front of the vehicle is divjided into two areas:
'yCentral area, arrow 1, directly in front of thevehicle.'yExpanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are loj
cated within the central area. A warning is isj
sued about pedestrians who are located within the extended area only if they are moving inthe direction of the central area.
