The tire monitoring system warns the driver if the tire  
pressure is too low.  
· Periodically check the tires for signs of wear or damage.  
Never exceed the maximum speed or the ca  
authorized load capacity of the mounted tires.  
The following tire monitoring systems are available for this  
vehicle:  
Too low tire pressure increases fuel consumption and  
tire wear.  
Tire monitoring system  
— Monitors various parameters while driving  
(including the rolling circumference) of all four tires using the  
ABS sensors (indirect measurement).  
When driving at high speed for the first time with new  
tires, the tires may spread slightly and, as a consequence,  
an air pressure warning may occur.

The reference pressure of the tire monitoring system is the  
recommended pressure for the tires fitted at the factory,  
measured when the tires are cold and with the vehicle fully  
loaded. The reference pressure corresponds to the data on the  
tire pressure sticker ÿ p. 342.

regularly to ensure that they have the correct pressure and  
that they show no signs of damage, such as punctures, cuts,  
cracks or dents. Remove foreign bodies that have been able to  
get stuck in the profile of the tire as long as they have not  
penetrated into it.  
If the correct pressure has been set in all four tires, the tire  
monitoring system must be readjusted ÿ p. 334. This is how  
the reference pressure is adapted to the current tire pressure.

WARNING  
,
Please note on  
page 334.  
at the beginning of this chapter,  
The intelligent technology of the tire monitoring system cannot  
overcome the limits imposed by physical laws and only works  
within the limits of the system. Improper handling of wheels  
and tires can cause sudden loss of pressure, detachment of  
the tread and even a tire blowout.  
Description of operation  
Among other things, the tire monitoring system compares  
the revolutions of each wheel and thus its rolling circumference  
using the ABS sensors.  
Rolling circumference can change:  
· Regularly check the tire pressure and always maintain  
the indicated values ÿ p. 342. If the pressure is too low,  
the tire could get so hot that

— If an emergency wheel is fitted.  
— If one wheel per axle has been changed.  
— Depending on the version, press the function

— Press the Tires feature button  
— Press the SET function button  
.
In the case of a sporty driving style, when driving  
on rough roads or in winter conditions, or when  
driving with snow chains, the tire monitoring system  
may take time to warn or not at all. do it.  
.
— If the pressure of all four tires corresponds to the  
required values, press the Confirm function button  
.
OR: Press the Cancel function button to cancel the  
process. The current tire pressure will not be saved  
and the system will not adapt.  
If the rolling circumference of the tires changes, the  
system alerts you with the warning light on the  
instrument panel.  
After a long drive (at least 20 minutes) at different  
speeds, the system automatically adapts the new values  
and monitors them.  
The recommended pressure for factory-fitted tires can  
be found on the tire pressure sticker on the driver's  
door pillar ÿ p. 342.  
The system must be adapted again in the following  
three cases:  
The pressure of all the tires must be checked monthly,  
including the spare or emergency wheel, when they are  
cold. The pressure must correspond to that prescribed  
by the vehicle manufacturer, which is stated on the tire  
pressure sticker. If the size of the fitted tires differs from  
those indicated on the type plate or on the tire pressure  
sticker, the correct pressure must be found.  
— If the tire pressures have changed  
ticos.  
— If any wheels have been changed.  
— If the wheels have been exchanged, e.g. For example, from  
the front to the rear axle.  
Adapt the system only when all tires have the correct  
pressure, measured when they are cold. To measure  
ta.  
the tire pressure, the vehicle must have been stationary  
for 3 hours or not have driven more than a few kilometers  
The tire monitoring system is not a substitute for regular  
tire maintenance and inspection. The driver is responsible  
for maintaining the correct tire pressure at all times, even  
if the system has not yet warned of too low pressure.

The tire monitoring system does not work  
when the ESC or ABS has a malfunction ÿ p. 204.  
The tire monitoring system also has a fault indicator  
After a warning that a tire pressure is too low,  
switch the ignition off and on again. Only then  
that is linked to the warning lamp. If the system has a  
fault, after switching on the figlansihtioens ftohreawpaprrnoixn.g1lamminpute,

then stays on.  
If the tire monitoring system indicates a malfunction, it  
will not be able to monitor tire pressure correctly. System  
failure can have various causes, e.g. For example,  
replacing a wheel or a tire. After replacing a wheel or tire,  
check whether the warning light indicates a system fault  
to ensure that the system is working properly ÿ p. 337.

Observe the legal provisions of the respective country  
regarding the tire pressure monitoring system.  
If a set of tires without sensors or whose sensors are  
not compatible with the vehicle is mounted on the  
vehicle, the control indicator flashes for approx. 1 minute,  
then stays on. Tire pressures will not be monitored. It is  
not possible to disconnect the system.  
Adjusting the tire pressure After any  
significant change in the vehicle's state of charge , the  
tire pressure must be checked and adjusted. The  
recommended tire pressure for the vehicle is listed on a  
sticker on the driver's door pillar or on the inside of the  
fuel filler flap.

Selecting the type of tires If you  
change to tires of other dimensions, it may be  
necessary to adapt the theoretical pressure to the new  
tires. If no adaptation is necessary, the selection menu  
will not be available.  
After switching on the ignition, the last measured tire  
pressures are first displayed; when the drive starts, the  
display is updated. If the pressure is too low, the affected  
tires and their actual values are marked ÿ fig. 240.

When the tires are not moving, the sensors do not send

WARNING  
WARNING  
If the pressure is not the same in all tires or is too low, the tires  
could be damaged or fail, loss of vehicle control could result in  
accidents, serious injury or death.  
· The pressure sensors are attached to special aluminum  
valves that are firmly screwed. When checking and correcting  
tire pressure, do not bend these valves.  
· If the warning light illuminates, stop immediately and check  
all tires ÿ p. 342.  
· If the caps are missing from the tire valves, the valves and  
sensors could be damaged. For this reason, always ride  
with them completely screwed on. Do not use metal caps.  
· If the pressure is not the same in all tires or is too low, it may  
increase tire wear, worsen driving stability and increase  
braking distance.  
· Do not use “Comfort” caps either, as they are not hermetic  
and could damage the sensors.  
· If the pressure is not the same in all tires or is too low, a tire  
could suddenly fail or burst, and you could lose control of  
the vehicle.

with bolt-on rims.  
Tires are the most stressed vehicle components and,  
in turn, the most underestimated. However, they are  
very important, since their narrow support surfaces are

· Do not use used wheels or tires without knowing their history.  
Used wheels and tires may be damaged, sometimes  
inconspicuously, which could cause tire damage, failure  
and loss of control of the vehicle.  
The useful life of the tires depends on their pressure,  
their handling and their correct mounting, as well as  
the driving style.
