Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space
Rparking spaces that are littered or overgrown
might be identified or measured incorrectly
Rparking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
Rsnowfall or heavy rain may lead to aparking
space being measured inaccurately
Rpay attention to the Active Parking Assist
PARKTRONIC warning messages during the
parking procedure (
Ypage 151)
Rwhen transportin gaload which protrudes
from your vehicle, you should not use Parking
Guidance
Rnever use Parking Guidance with snow chains
or an emergencys pare wheel fitted
Rmake sure that the tire pressures are always
correct. This hasadirect effect on the steer-
ing instructions
Rthe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in fronta nd
behind it and the conditions of the location. In
some cases, Parking Guidance may guide you
too far or not far enough into aparking space.
In some cases, it may also lead you across or
ont othe curb. If necessary, cancel the park-
ing procedure with Parking Guidance.
Detecting parking spaces

MOExtended tires (tires with run-flat
characteristics)
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires.
MOExtended tires may only be use dinconjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes-
Benz.
Notes on driving with MOExtended tires with a
flat tire (
Ypage2 47).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommendedt hat you additionally
equip you rvehiclew ithaTIREFIT kit if you mount
tires that do not feature run-fla tcharacteristics,
e.g. winter tires. ATIREFIT kit can be obtained
from aqualified specialist workshop.
Winter operation
General notes
Have you rvehiclew inter-proofed at aqualified
specialist workshopatt he onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypage2 80).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on you rvehicle
to M+S tires .Using summe rtires at very cold
temperatures coul dcaus ecracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damaged tires can caus etire inflation pres-
sure loss. As aresult, you coul dlose control of
you rvehicle. There is arisk of accident.
Check the tires regularl yfor signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibleg rip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e266).
XVehicles for Canada: restart the tire pres-
sure loss warning system (Ypag e267).
XRestart the tire pressure monitor
(Ypag e267).

spare wheel (
Ypag e285).
Snowc hains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.
262Wintero peration
Wheels and tires

To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralwaysinstall snow chains in pairs to the
rear wheels.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz,ora re ofacorresponding
standard of quality. For more information,
please contact aqualified specialist workshop.
If you inten dtomount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations (
Ypage 284).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to aroad that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
You may wish to deactivate ESP
®when pulling
away with snow chains installed (Ypage 60).
You can thereby allow the wheels to spin in a
controlled manner ,achieving an increased driv-
ing force (cutting action).
Information about driving with an emergency
spare wheel (

Tire pressure
Tire pressur especifications
Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correctt he tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specification sare vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factor ycan be found on the
labels described here.
Operation with an emergency sparew heel:
information on operation with an emergency
spare wheel can be found in the general notes in
the "Emergency spare wheel" section
