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 172.
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.

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, de‐
pending on the model, tire temperatures. It
shows the actual values read; they may vary depending on driving style or weather condi‐
tions.
Carry out reset Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.

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.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. To correct the tire in‐
flation pressure3.Repair flat tire with the Mobility System or
replace the damaged wheel.

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.
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‐
