384 Operation
Tires and wheels
Reactivating the Run Flat Indicator
The tire inflation pressure monitor must be
reactivated in the following situations:

if you have changed the tire inflation
pressure

if you have replaced the wheels or tires

if you have installed new wheels or
tires
Using the tire placard on the driver’s
door B-pillar or, if available, the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is
correct.
Switch on the ignition (page 39).
Make sure the standard display menu
appears in the multifunction display
(
page 166).
Press buttonk orj repeatedly
until the following message appears in
the multifunction display:
Press the reset button on the instru-
ment cluster (
page 156).
The following message will appear in
the multifunction display:
Restart
Run Flat Indicator?
Warning!G
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the placard on the driver’s
door B-pillar or fuel filler flap.
The Run Flat Indicator does not replace reg-
ular checks of the tire inflation pressures
since a gradual pressure loss in all four tires
cannot be detected by the Run Flat
Indicator.
The Run Flat Indicator is not able to issue a
warning due to a sudden dramatic loss of
tire inflation pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
ing the brakes and avoiding abrupt steering
maneuvers.
Warning!G
The Run Flat Indicator can only warn you in
a reliable manner if you have set the correct
tire inflation pressures for each tire.
If an incorrect tire inflation pressure was
set, the system will monitor the pressure
according to the incorrect value.

387 Operation
Tires and wheels
Reactivating the TPMS
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Using the tire placard on the driver’s
door B-pillar (
page 376) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
page 360), make sure the tire
inflation pressure of all four tires is cor-
rect.
Switch on the ignition (page 39).
Press buttonè orÿ on the
multifunction steering wheel repeat-
edly until the standard display menu
appears in the multifunction
display (
page 166).
Press thej or kbutton repeat-
edly until you see the following mes-
sage:
Tire pressure monitor
active
Menu: R-button
Press the reset button (page 156).
The following message will appear in
the multifunction display:
Restart tire
pressure monitor?
Press the æbutton.
The following message will appear in
the multifunction display:
Tire pressure monitor
restarted
After driving a few minutes the current
tire inflation pressure values are
accepted as reference pressures and
then monitored.
If you wish to cancel activation:
Press the çbutton.
Warning!G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might loose control over the vehicle.
iReactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the placard on the driver’s door
B-pillar (
page 376). Some vehicles may have
supplemental tire pressure information for driv-
ing at high speeds (
page 381) or for vehicle
loads less than the maximum loaded vehicle con-
dition (
page 382). If such information is pro-
vided, it can be found on the inside of the fuel
filler flap.

390 Operation
Tires and wheels
Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
(
page 166).
Press thej or kbutton repeat-
edly until you see the current inflation
pressures for each tire appear in the
display or the following message ap-
pears in the display
Tire pressure
displayed after
driving for
a few minutes
Press the reset button (page 156).
The following message will appear in
the multifunction display:
Restart tire
pressure monitor?
Press the æbutton.
The following message will appear in
the multifunction display:
Tire pressure monitor
restarted
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s
specified range. Afterwards the current
tire inflation pressures are accepted as
reference pressures and then moni-
tored.
If you wish to cancel activation:
Press the çbutton.Potential problems associated with
underinflated and overinflated tires
Underinflated tires
Underinflated tires can:

cause excessive and uneven tire wear

adversely affect fuel economy

lead to tire failure from being
overheated

adversely affect handling
characteristics
iReactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the placard on the driver’s door
B-pillar (
page 376). Some vehicles may have
supplemental tire pressure information for driv-
ing at high speeds (
page 381) or for vehicle
loads less than the maximum loaded vehicle con-
dition (
page 382). If such information is pro-
vided, it can be found on the inside of the fuel
filler flap.
Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
