convertible top is opened. <
If it is no longer possible to operate the cover 
after it has been actuated several times in 
immediate succession or after the cover has 
remained in an interm ediate position for a 
longer period, then the  convertible top drive has 
overheated. If possible, close the convertible top and allow 
the drive unit to cool for a few minutes.
Operating while driving
You can open or close the convertible top while 
driving, as long as the car is not moving faster 
than approx. 25 mph/40 km/h.
If you accelerate to ov
er 30 mph/50 km/h while 
the convertible top is moving, the procedure is 
interrupted.
While operating the convertible top, pay 
close attention to the surrounding traffic; 
otherwise, an accident may happen. Try to 
avoid operating the convertible top while 
reversing the vehicle since the rear view is very 
limited during the convertible top's movement. 
Do not operate the convertible top while driving 
in windy conditions. Do not drive faster than 
30 mph/50 km/h; otherwise, damage to the 
vehicle can occur. <

electrical consumers in order to preserve the 
battery. <
Radio readiness and ignition off
All indicator and warnin g lamps as well as 
displays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas; 
otherwise, the inhalati on of toxic exhaust 
gases can cause loss of consciousness and 
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly 
toxic gas. Never leave an unattended vehicle 
with the engine running; otherwise, such a 
vehicle represents a po tential safety hazard.
Before leaving the car with the engine running, 
place the transmission in  neutral or move the 
selector lever to positi on P and forcefully apply 
the parking brake to prevent the car from 
moving. <
Do not wait for the engine to warm up while the 
vehicle remains stationary. Start driving right 
away, but at moderate engine speeds. Avoid frequent starting in quick succes-
sion as well as repeated start attempts in 
which the engine does no t start. Otherwise, the 
fuel is not burned or  incompletely burned and 
there is a danger of overheating and damaging 
the catalytic converter. <

System limitations
Sudden serious tire damage caused by 
external influences ca
nnot be indicated in 
advance.<
The system does not function correctly if it has 
not been reset. For example, a flat tire may be 
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat 
tire:
> When a wheel without TPM electronics is 
installed.
> Interference with TPM  by other systems or 
devices with the same transmission 
frequency.
Status display
The current status of the Tire Pressure Monitor 
TPM can be displayed on the Control Display, 
e.g., whether or not the TPM is active.
1. "Vehicle Info"
2. "Vehicle status"
3. "Tire Pressure Monitor - TPM"
The status is displayed.
Status indicator on the Control Display
The color of the tires represents the status of 
the tires and the system.
A change in the tire in flation pressure during 
driving is taken into account.
A correction is only re quired when this is 
indicated by the TPM.
Green wheels
The inflation pressure corresponds to the 
desired state.
"TPM active" appears in  the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire.
All wheels yellow
> There is a flat tire or substantial loss of tire 
pressure in several tires.
> The system was not reset after a wheel 
change and thus issues a warning based on 
the inflation pressure s initialized last.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
>TPM is being reset.
> Interference from systems or devices that 
use the same radio frequency.
> Malfunction.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed, 
reset the system.
