Tire Pressure - Mercedes-Benz E-Class Coupe 2022 Operator's Manual

Some tire pressure tables only show the rim diam-
eter instead of the complete tire size, e.g. R18
The rim diameter is part of the tire size and can
be found on the tire side wall ( page 320).

Checking t Chec king the tir he tire pr e pressur essure manually e manually
Read the tire pressure recommended for the
#
current operating conditions from the Tire and
Loading Information placard or the tire pres-
sure table. Observe the notes on tire pressure.
Remove the valve cap of the tire to be

checked.
Press the tire pressure gauge securely onto

the valve.
Read the tire pressure.
#
If the tire pressure is lower than the recom-
#
mended value, increase the tire pressure to
the recommended value.
If the tire pressure is higher than the recom-
#
R18. mended value, release air. To do so, press
down the metal pin in the valve, e.g. using the
tip of a pen. Then, check the tire pressure
again using the tire pressure gauge.
Screw the valve cap onto the valve.

ANGER GER Risk of accident due to incorrect

tire pressure

Each tire, including the spare (if provided),
should be checked monthly when cold and
in ated to the in ation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire in ation pressure label. (If
your vehicle has tires of a di erent size than
the size indicated on the vehicle placard or
tire in ation pressure label, you should deter-
mine the proper tire in ation pressure for
those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
page 306)
/
sure telltale when one or more of your tires is
page 308)
signi cantly under-in ated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and in ate them to the proper pres-
sure. Driving on a signi cantly under-in ated
em
tire causes the tire to overheat and can lead
e monitor oring syst ing system em to tire failure. Under-in ation also reduces fuel
e ciency and tire tread life, and may a ect
the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if under-in ation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
