Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive ove r a pot­
ho le or hit a curb while parking . It is usua lly
not possible to see whether the radial tires
used today are under inflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
" long." See
c::> page 233 , Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold ," le t air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the l oad (passengers and luggage) and kind of
driving you plan to do .
I f the pressure in any tire is too low, note the
diffe rence between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the cor rect pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as lis ted on the on
your veh icle and in this manual and the k ind
of dr iv ing you pla n to do .
Never e xceed th e ma ximum inflatio n pres ­
sure li sted on th e tire s id ewall for an y rea ­
son .
Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the req uired ti re pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the driver's side B-pi llar . - Tu
rn the va lve stem cap counter -clockwise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressu res should only be checked
and adj usted when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When should I check the tire pr essure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
the refore be che cked at least once a mo nth
and always before sta rting a jo urney. Do not
f orget to c heck the ti re p ress ure for the spare
whee l
c::> page 247.
When should I adjust the tire pressures?
Adjust the t ire pr essure to the load you are
ca rrying. After cha ng ing a whee l
or replacing
whee ls you have to adjust the ti re p ress ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres­
s u re monitoring system
c::> page 243 .
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RIJ appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping abi lity.
- Inco rrect tire pressures and/or underin ­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout a nd sudden de­
f lation, ca using loss of veh icle cont ro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The appli cable pressure values are locat ­
ed on a sticker on the dr iver's side B-pil-

signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.

s age
Using the ABS sensors, the tire pressure moni­
toring system compa res the tire tread circum­
ference and vibration characteristics of the in­
dividual tires .
If the pressure changes in one
or more tires, th is is indicated in the instru­
ment cluster display with an indicator light
IE and a message ¢ fig. 161 . If only one t ire
is affected, the location of that t ire will be in­
d icated. The message turns off after a few mi­
nutes. You can disp lay the message again
¢ page 28.
The tire pressures must be stored in the menu
d isplay aga in each time the pressures change
(switching between part ia l and full load pres­
sure) or after chang ing or replac ing a tire on
your ve hicle ¢
page 245. The tire pressure
monitoring system on ly monitors the ti re
press ure you have stored . You can find the rec­
ommended tire pressures for your vehicle on the
labe l on the driver's doo r pillar

Tire tread circumference and vib ration charac­
teristics can change and cause a tire pressure
warning if:
- I f the tire pressure in one or more ti res is
t oo low.
- The tire has structural damage.
- The tire was replaced or the t ire pressure
changed and it was not stored again
