"Tire Pressure Monitor - TPM"
The status is displayed.
Malfunction
The yellow warning lamp flashes and 
then lights up continuously. The tires 
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can 
be detected.
A message like this is displayed in the following 
situations:
>
In case of a malfunction:
Have the system checked
>
If a wheel without TPM electronics is 
mounted, e.g. a compact wheel
*
>
If TPM is temporarily interfered with by 
other systems or devices which use the 
same radio frequency
Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring 
Systems
Each tire, including the spare (if provided), 
should be checked monthly when cold and 
inflated to the inflation pressure recommended 
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehi-
cle has tires of a different size than the size indi-
cated 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 underinflated. 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 underinflated tire 
causes the tire to overheat and can lead to tire 
failure. Underinflation also reduces fuel effi-
ciency 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 underinflation 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 indicator to indicate when 
the system is not operating properly. The 
TPMS malfunction indicator is combined with 
the low tire pressure telltale. When the system 
detects a malfunction, the telltale will flash for 
approximately one minute and then remain con-
tinuously illuminated. This sequence will con-
tinue upon subsequent vehicle startups as long 
as the malfunction exists. When the malfunc-
tion 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 
replacement or alternate tires or wheels on the 
vehicle that prevent the TPMS from functioning 
properly. Always check the TPMS malfunction 
telltale 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.
Active steering*
The concept
The active steering actively varies the steering 
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies 
the steering force required for steering depend-
ing on the vehicle's speed.
When you are driving in the low road speed 
range, e.g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
