Self-leveling suspension*
Malfunction
The warning lamp for self-leveling 
suspension lights up yellow and a 
message is shown on the Control 
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at 
the front, and possibly also on one side – rear 
left compared to rear right –, proceed to the 
nearest BMW Sports Activity Vehicle Center or 
a workshop that works according to BMW 
repair procedures with correspondingly trained 
personnel. Drive with appropriate caution in the 
meantime. The vehicle has reduced ground 
clearance and driving comfort may be notice-
ably reduced. Even if the orientation of the vehi-
cle is normal, when a malfunction is indicated 
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a 
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in 
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change 
in the rolling circumference and therefore the 
rotation speed of the corresponding wheel. The 
system detects this change and reports it as a 
flat tire.
Function requirements
In order to assure the reliable reporting of a flat 
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after 
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.
<
System limits
The Flat Tire Monitor cannot indicate 
sudden severe tire damage caused by 
outside factors and does not detect a natural, 
even pressure drop in all four tires.
<
In the following situations, the system could be 
delayed or malfunction:
>
System has not been initialized
>
Driving on snowy or slippery road surface
>
Sporty driving style: slip in the drive wheels, 
high lateral acceleration
>
Driving with snow chains
*
When you are driving with the compact wheel
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving, 
which can be interrupted at any time. 
When driving resumes, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
or with the 
compact wheel
