Checking the tire pressures
Important safety notes Observe the notes on tire pressure
( Y
page 387).
Information on air pressure for the tires on your
vehicle can be found: R
on the vehicle's Tire and Loading Information
placard on the B-pillar ( Y
page 394)R
in the tire pressure table in the fuel filler flap
( Y
page 189)R
in the "Tire pressure" section Checking tire pressures manually To determine and set the correct tire pressure,
proceed as follows: X
Remove the valve cap of the tire that is to be
checked. X
Press the tire pressure gage securely onto the
valve. X
Read the tire pressure and compare it to the
recommended value on the Tire and Loading
Information placard or the tire pressure table
( Y
page 387). X
If the tire pressure is too low, increase the tire
pressure to the recommended value. X
If the tire pressure is too high, release air. To
do so, press down the metal pin in the valve,
using the tip of a pen for example. Then check
the tire pressure again using the tire pressure
checker. X
Screw the valve cap onto the valve. X
Repeat these steps for the other tires.
Tire pressure monitor
General notes If a tire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the tire
pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only
functions if the corresponding sensors are
installed in all wheels.
Information on tire pressures is displayed in the
multifunction display. After a few minutes of
driving, the current tire pressure of each tire is
shown in the Service menu of the multifunction
display; see illustration (example).
For information on the message display, refer to
the "Checking the tire pressure electronically"
section ( Y
page 392).390

Important safety notes
G WARNIN G
Eac h tire, includin g th e spar e (if provided),
should be checke d at least once every two
week s when cold and inflated to th e pressur e
recommended by th e vehicl e manufacturer
on th e Tir e and Loading Information placard
on th e driver' s door B-pillar or th e tire pres-
sur e label on th e inside of th e fuel filler flap . If
your vehicl e has tires of a differen t siz e than
th e siz e indicated on th e Tir e and Loading
Information placard or, if available, th e tire
pressur e label, you should determine th e
proper tire pressur e for those tires .
As an added safet y feature, your vehicl e has
been equipped wit h a tire pressur e monitoring
system (TPMS) that illuminate s a low tire pres-
sur e telltale when on e or mor e of your tires
are significantly underinflated. Accordingly,
when th e low tire pressur e telltale lights up,
you should stop and chec k your tires as soo n
as possible , and inflat e them to th e proper
pressure. Drivin g on a significantly underin-
flated tire causes th e tire to overheat and can
lead to tire failure.
Underinflation also reduce s fuel efficiency
and tire tread life , and may affec t th e vehicle's
handlin g and stopping ability. Pleas e note that
th e TPM S is no t a substitut e for proper tire
mainte
nance , a nd it is th e d river' s responsi-
bilit y to maintai n correc t tire pressure, eve n if
underinflation has no t reached th e level to
trigge r illumination of th e TPM S low tire pres-
sur e telltale.
Your vehicl e has also been equipped wit h a
TPM S malfunction indicator to indicat e when
th e system is no t operating properly. The
TPM S malfunction indicator is combined wit h
th e low tire pressur e telltale. When th e sys-
te m detects a malfunction , th e warning lamp
will flas h for approximately a minute and then
remain continuously illuminated. This
sequenc e will be repeated every time th e vehi-
cle is started as lon g as th e malfunction
exists. When th e malfunction indicator is illu- minated, th e system may no t be able to detec t
or signal low tire pressur e as intended.
TPM S malfunction s may occur for a variet y of
reasons, includin g th e installation of incom-
patible replacemen t or alternate tires or
wheels on th e vehicl e that preven t th e TPM S
from functioning properly. Always chec k th e
TPM S malfunction telltale after replacing on e
or mor e tires or wheels on your vehicl e to
ensur e that th e replacemen t or alternate Tires
and wheels allow th e TPM S to continue to
function properly.
It is th e driver' s responsibilit y to set th e tire
pressur e to that recommended for cold tires
whic h is suitable for th e operating situation
( Y
page 387). Not e that th e correc t tire pressur e
for th e curren t operating situation must first be
taught-in to th e tire pressur e monitor. If there is
a substantial loss of pressure, th e warning
threshold for th e warning message is aligned to
th e referenc e value s taught-in . Restart th e tire
pressur e monitor after adjusting th e pressur e of
th e cold tires ( Y
page 392). The curren t pres-
sures are saved as ne w referenc e values. As a
result , a warning message will appear if th e tire
pressur e drops significantly.
The tire pressur e mon ito r does no t w
arn you of
an incorrectl y set tire pressure. Observ e th e
note s on th e recommended tire pressur e
( Y
page 387).
The tire pressur e monitor is no t able to warn you
of a sudde n loss of pressure, e.g. if th e tire is
penetrated by a foreign object. In th e event of a
sudde n loss of pressure, brin g th e vehicl e to a
halt by braking carefully. Avoid abrup t steering
movements.
The tire pressur e monitor has a yellow warning
lamp in th e instrumen t cluste r for indicating
pressur e loss or a malfunction . Whether th e
warning lamp flashes or lights up indicates
whether a tire pressur e is to o low or th e tire
pressur e monitor is malfunctioning :R
if th e warning lamp is lit continuously, th e tire
pressur e on on e or mor e tires is significantly
to o low. The tire pressur e monitor is no t mal-
functioning . R
if th e warning lamp flashes for aroun d a
minute and then remain s lit constantly, th e
tire pressur e monitor is malfunctioning .
In addition to th e warning lamp , a message
appear s in th e multifunction display. Observ eTire pressure 391

G WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel
bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
G WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
( Y
page 405).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
wheel.
! Mercedes-AMG vehicles: during removal
and repositioning of the wheel, the wheel rim
can strike the ceramic-brake disc and dam-
age it. Therefore, you should proceed care-
fully and get a second person assist to you.
Alternatively, you can use a second alignment
bolt.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt. X
