Tire pressure monitoring system*
Applies to vehicles: with tire pressu re monitoring system
General notes ' J
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom ­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has t ires of a d ifferent size
than the size indicated on the vehicle placard or tire inflation pres­
sure label, you should determine the proper tire inflation pressure
for those ti res.)
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that i lluminates a low tire
pressure tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low tire pressure telltale illu­
minates, you shou ld stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflat ion also reduces fuel efficiency and t ire tread
life, and may affect the vehic le's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il luminat ion of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS ma lfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the tellta le wi ll
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the ma lfunction 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 insta
llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly. Always
check the TPMS malfunction tellta le after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels a llow the TPMS t o continue to funct ion
properly. •
Applies to vehicles: with tire pressur e monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire p ressure monitoring system senses a significant
loss of air pressure in one or severa l tires, text messages and ye llow
sy mbo ls appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated
=> page 13 .
Th e warning light l also i lluminates in the case of a system
malfunction.
Be aware tha t tire pressure is a lso dependent on the temperature of
the tire . For every 18 °F (1 O °C) increase in tire temperature, tire pres ­
sure increases by about 1.5 psi (0 .1 ba r). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly ca li­
b rated, tire pressure on all four tires shou ld be checked a t regu lar
interva ls, adjusted if necessary, and saved in the proper setting
(reco mmended pressure) :::>
page 266.
The tire pressure is shown either on the driver's side 8 -pi llar or on
the inside of the fuel fi ller flap. _..

-Inspect all tires.
- Change the tire if necessary~ page
272.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated .
In addition, the tire symbol ,_, appears in the display together with
the message
Please check tire pressure=> page 265, fig. 185.
After a few seconds, the message disappears again. If you would
like to show the message again, press the Set/Check button
=>
page 8, fig. 2 @ .
[ i ] Tips
• In the case of an intentional loss of air pressure, such as when
readjusting tire pressure, the pressure must be stored again after­
ward =>
page 266.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The yellow symbol disappears when the tire pressure is
corrected and the new pressure is stored in the system=>
page 266.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition, you must then initialize the new tire pressures in the tire pressure moni­
toring system =>
page 267. •
Applies to vehicles: with tire pr essu re mon itoring system
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring .
1 1 1 J
Fig. 186 Car: Tire pres­
sure monitoring
system
In order for the tire pressure monitoring system to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, such as when the load condition of your vehicle changes. Proceed as follows:
Correcting tire pressure
- Check the pressure in the tires.
- Adjust air pressure as needed to comply with the infor- mation on the label located on the label located either on
the driver's side 8 -pillar or on the inside of the fuel filler
flap .
Saving tire pressures
-Turn on the ignition.
- Press the button~ fig. 186 for approximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times. ..,.

•
All pressure warning indicators in the display will be canceled.
Fo llowing each intent ional change in specified pressures, tire pres­
sures must be saved again .
After the pressures are saved, the tire pressure monitoring system
measures the current tire pressures and saves them as the new
specified pressures.
[ i] Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located either on the driver's side B -pillar or on the
inside of the fuel filler flap. The tire pressure label lists the recom­
mended cold tire inflation pressures for the vehicle at its maximum
capacity weight and the tires that were on your vehicle at the time
it was manufactured. For recommended tire pressures for normal
load conditions, please see chapter~
page 247.
• The tire pressure monitoring system helps the driver monitor tire
pressures, but the driver is still responsible for maintaining the
correct tire pressure. •
Applies to vehicles: with tir e pressure monitor ing system
Wheel change
If a wheel is changed, the wheels that were exchanged
have to be reprogrammed.
- Turn on the ignition.
- Press the button=>
page 266, fig. 186 for approximately 5
seconds. You will hear a beep and the symbol in the
button flashes three times.
Programming is necessary:
• after the tires have been rotated on the vehicle, or the spare tire
is used, •
if tires with new wheel sensors are used.
All pressure warning indicators in the display will be canceled. The
system malfunction error message will not disappear until the
vehicle is underway. With pressing the button~
page 266, fig. 186,
the reprogramming of the new sensors and storing of actual pres­
sures starts . This learning phase can take up to 10 minutes driving
time.
During the learning process the tire pressure monitoring system is
not available. •
Applies to vehic les: with tir e pr essure monitor ing system
Malfunctions *
A malfunction can have various causes.
Fig. 187 Display:
System malfunction
If the '-warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additionally the
~ f ig. 187 symbol appears in the display, the
tire pressure monitoring system is not available . This can have
various causes.
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed. .,,_
