24 2 T ire s and wheel s
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle.
I t is important to check the tire pressu re when
the tires a re cold.
- Read the requ ired t ire pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the drive r's side 8-p illar.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressu re gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold. The
sl igh tly ra ised p ressu res of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the ti re pres sure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before start ing a jou rney. Do not
fo rget to check the tire pressure for the spare
wheel
i::!> page 258.
When should I adju st the tire p re ss ure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
sto re t he new ti re press ures in the t ire pres­
sure mon itor ing system*
i::?> page 253.
_8 WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
contro l, co llision, ser ious persona l injury
or even death.
- When the warning symbo l
RI] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability. -
Incorrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
flation, caus ing loss of veh icle control.
- The driver is responsible for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­ ed on a sticke r on the dr iver's s ide 8-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the t ire pres­
sure mon itor ing* system can work cor­
rectly.
- The use of incorrect t ire p ressure va lues
can lead to acc idents or other damage.
Therefore it is essential t hat the drive r
observe the spec ified tire pressure values
for the tires and the correct pressures for
the function of the t i re press ure monitor­
ing system*.
- Always inflate tires to the recommended
and correct ti re press ure before driving
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ress ure and add
a ir as req uired.
Q) Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory insta lled
valve stem caps o n all whee ls are sec urely
mounted on the valve.

2 58 What do I do n ow ?
Space-saving spare tire (compact spare
tire)*
Applies to vehicles: with space-saving spare tire

Tak ing out th e spar e tir e
• Lift the cargo floor by the plastic handle
¢fig. 194.
• Hook the handle into the luggage compart­
ment weather strip.
• Turn the large screw¢
fig. 194 counter­
clockwise.
• Take out the spare tire .
• Always store the vehicle too l kit, the jack*
and the repla ced ti re in the l uggage com­
partment~
page 130.
• Unhook the cargo floor before clos ing the
rear lid.
Using the spare tire (compact spare tir e)
The compact spare tire is on ly intended for
emergenc ies until you can reach a repair shop.
Replace it as quickly as poss ible with a stand­
ard wheel and tire.
There are some restrictions on the use of the compact spare tire. The compact spare t ire
has been des igned specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare tire from another type of vehicle .
Snow chains
Fo r technical reasons, the use of snow chains
on the compa ct spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare whee l w ith ti
re instead of a rear tire. Install the snow
chains on the rear tire and use it to replace
the defect ive front t ire.
A WARNING
=
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
d icators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as poss ible with the
normal whee l and tire.
-Afte r mounting the compact spare tire,
the t ire pressure must be checked as
soon as possible. The tire pressure of the
compact spare t ire must be 4. 2 bar; oth­
e rwise, you risk having an a cciden t.
- D o not dr ive faste r th an 50 mph (80 km/
h). Yo u ris k havi ng a n accident.
- Avoid full-thrott le acceleration, heavy
b rak ing, and fast corne ring. You risk hav­
i n g a n accident.
- Neve r d rive using more than one spa re
wheel and ti re. You r is k having an acci­
dent.
- Normal summer or win ter t ires must not
be mou nte d on the compa ct spare wheel
rim.
- For technical reasons, the use of t ire
chains on the spare tire is not permit ted .
If it is necessary to drive with t ire chains,
the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The new ly available front wheel
must then be installed in place of the
rear whee l with the flat tire. Installing
the t ire chain before mounting the whee l
and tire is recommended.
