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. _..

& WARNING
• When the t ire pres sure monitoring sy stem warning light is l it ,
one or more of your tire s is significantly underinflated . You should
stop and che ck your tires as soon as possible , and inflate them to
the proper pres sure as ind icated on the vehicle's tire pressure
label :::::,
page 247 . Driving on a signifi cantly unde rinflated tire
causes the tire to overheat and can lead to tire failure. Underinfla­
tion also is likely to impair the vehicle's handling and stopping ability .
• Do not adju st tire pressure when tire temperature is e xcess ive.
This could lead to serious tire damage and even cause the tire to
burst , with the additional dan ger of an accident.
W For the sake of the environment
D riving with u nder inflated tires r educes fue l effi ciency and ti re
tread life.
[ i J Tip s
• Each tire, including the spare , should be checked monthly when
t he tempe rat ure of the t ires is a bout t he sa me as amb ient a ir
temperature and set to the recommended inflation pressure as
speci fied o n the ti re pre ssure label :::::,

• The factory supplied spare whee l is equipped with a sensor for
t he ti re press ure m onit ori ng sys te m. As long as the spare w hee l is
not mounted, the t ire pressure of this tire wil l not be monitored .
• T he tire pressure mon itori ng system help s t he d river mo nitor ti re
pressures, but the driver is stil l responsible for maintaining the
c orrect tire press ure.
• T ire pressure must only be adjusted when the temperature of the
ti res is abou t th e sam e as ambie nt air te mperatu re.
• When t ires a re replaced, the sen so rs and valves shou ld not be
e xcha nged . T he va lve co re, nut, va lv e sea ling and sea l was her (replacement kit) needs to be replaced
. If necessary, the valve and
t he wheel electr onics have to be rep laced.
• I f you should put different whee ls and tires on your vehic le (e.g.

[ 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 .

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. •

& WARNING
Always store jacking equipment, spare wheel in the luggage
compartment. Tighten screw for the spare wheel securely. Under
no circumstances should you store the spare wheel or jack and
tools unsecured in the passenger compartment. This could cause
serious personal injury to passengers in the vehicle in case of a
collision.
• The compact spare tire is for temporary use only and is so
marked on the sidewalls.
• Do not drive at speeds exceeding 50 mph (80 km/hi with the
compact spare wheel mounted. Also rapid acceleration, hard
braking and hard cornering must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, loss of vehicle control and injury to vehicle occu­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose the chain, as well as
control of the vehicle .
• If you have a flat front tire in road conditions which require
snow chains, first remove the undamaged rear wheel and mount
the compact spare wheel in its place. Then remove the damaged
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. This wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure promptly.
• Never use two or more compact spare tires at the same time.
0 Note
When using the compact spare wheel, note the following: •
After installing the compact spare wheel, the tire inflation pres­
sure should be checked and, if necessary, increased to 60 psi (4 .2
barl.
• The load carrying capacity is marked on the tire sidewal ls and
must not be exceeded .
• After installing the compact spare wheel, make sure that you
remount the flat tire in its storage area properly .
• The compact spare tire should be properly remounted in its
storage area as soon as the standard road tire can be replaced.
• Because the compact spare tire was specifically designed for
your vehicle, it must not be used on any other vehicle . Likewise,
compact spare wheels from other vehic les must not be used on your
vehicle.
• The compact spare tire must not be mounted on any other
wheels, nor must standard tires, snow tires, wheel covers or trim
rings be used with the compact spare wheel. If such use is
attempted, damage to these items or other vehicle components
may occur.
[ i] Tips
Check the inflation pressure of the compact spare tire (60 psi/4 .2
bar) periodically to keep the tire ready for use .•
