tion pressure table on page 299), for example,
if higher inflation pressure is necessary when
transporting heavy loads, etc.
This is done in the vehicle's menu system. See
page 189 for a description of the menu system.
To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure and
put the ignition in mode I or II (see page
83 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settings Tyre pressure
4. Press OK/MENU, select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph
(40 km/h) continuously for at least
10 minutes.
> When the calibration message is no
longer displayed, TPMS has been reca-
librated to the new inflation pressure.
Activating/deactivating TPMS (Canadian
models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
83 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select

4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as
optional equipment. The vehicle must be
equipped with the Tire Pressure Monitoring
System (TPMS) if tires of this type are installed.
Tires of this type have specially reinforced
sidewalls that make it possible to continue
driving to a limited extent even though the tire
has lost some or all of its inflation pressure.
These tires are mounted on special rims (nor-
mal tires can also be mounted on these rims).
If an SST tire loses inflation pressure, the yel-
low TPMS symbol illuminates in the instrument
panel and a text message is also displayed. If
this happens, reduce speed to not more than
50 mph (80 km/h). The tire should be replaced
as soon as possible.
Drive carefully; it may be difficult to determine
which tire is damaged. To find the damaged
tire, check the inflation pressure in all four tires.
WARNING
• SST tires should only be mounted by
service technicians who are familiar
with tires of this type.
• SST tires may only be mounted on vehi-
cles equipped with TPMS.
• Do not drive faster than 50 mph
(80 km/h) if TPMS indicates that a tire
has lost inflation pressure.
• Do not drive farther than 50 miles
(80 km) before replacing a damaged
SST tire.
• Drive carefully and avoid e.g., hard
braking or fast turns.
• SST tires must be replaced if they are
damaged. A tire of this type cannot be
repaired.
