Do not move hardtop
When the rollover protection system is
extended, do not move the hardtop. Other‐
wise, 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 hardtop. The protective function of
the system is then restored.1.Pull the release lever in the safety frame up
and hold it, arrow 1.2.Push the safety frame down, arrow 2.3.Release the release lever only if the safety
frame was pushed back almost completely.4.Push the safety frame down until it notice‐
ably engages. To do this, the safety frame
must be pressed far into its holder; high
levels of force are required.
Do not bend via the safety frame
Should the safety frame not have
snapped in place when it is released, then
it moves back up with jerking movements.
When it is released, do not bend via the
safety frame; otherwise, there is a risk of
injury with a safety frame that is not en‐
gaged.◀
Slowly reduce pressure on the safety
frame in order to test whether it is latched.5.Proceed likewise with the second safety
frame.Malfunction
A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM The concept
The system monitors tire inflation 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 inflation pressure
and tire temperature.
Hints Tire damage due to external factors
Sudden tire damage caused by external
circumstances cannot be recognized in ad‐
vance.◀
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 188.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment 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 (TPM)"Seite 100ControlsSafety100
Online Edition for Part no. 01 40 2 956 860 - X/14

The status is displayed.Status control display
Tire and system status are indicated by the
color of the wheels and a text message on the
Control Display.
All wheels green
System is active and will issue a warning rela‐
tive to the tire inflation pressures stored during
the last reset.
One wheel is yellow
A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow A flat tire or major drop in inflation pressure in
several tires.
Wheels, gray
The system cannot detect a flat tire. Reasons
for this may be:▷The system is being reset.▷Malfunction.
Status information
The status control display additionally shows
the current tire inflation pressures and possibly
tire temperatures. It shows the actual values
read; they may vary depending on driving style or weather conditions.
Carry out reset
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
On the Control Display and on the vehicle:
1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive off.5.Reset tire inflation pressure:"Perform
reset".6.Drive away.
The tires are shown in gray and the status is
displayed.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The reset is
completed automatically while driving.
After a successfully completed Reset, the
wheels on the Control Display are shown in
green and "Tire Pressure Monitor (TPM)
active" is displayed.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
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.▷No reset was performed for the system.
The system therefore issues a warning
based on the tire inflation 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 196, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's 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.◀
A low tire inflation pressure might turn on DSC

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 shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. Then perform the reset.
If an identification is not possible, please
contact the service center.2.Fixing a flat tire, where applicable 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 shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. 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 cargo load, driv‐
ing 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 differ‐
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 ma‐
neuvers or driving 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 shorter or lon‐
ger depending on the driving speed, road con‐
ditions, 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.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are
longer and the self-steering properties will
change.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a 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 tire inflation pressure check
message
A Check Control message is displayed in the
following situations▷The system has detected a wheel change,
but no reset was done.▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.Seite 102ControlsSafety102
Online Edition for Part no. 01 40 2 956 860 - X/14

System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when 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 inflation pressure can be de‐
tected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.
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 vehicle
that 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.Seite 103SafetyControls103

FTM Flat Tire MonitorThe concept
The system detects tire inflation pressure loss
on the basis of rotation speed differences be‐
tween the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. This will be
detected and reported as a flat tire.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every 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.
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
When initializing the once set inflation tire
pressures serve as reference values in order to
detect a flat tire. Initialization is started by con‐
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 - 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 maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 196, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's 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 needed.
System limits Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized
in advance.◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:
