261 Operation
Tires and wheels
Important guidelines

Only use sets of tires and rims of the
same type and make.


Tires must be of the correct size for the
rim.


Break in new tires for approximately
60 miles (100 km) at moderate
speeds.


Regularly check the tires and rims for
damage.


If vehicle is heavily loaded, check tire
pressure and correct as required.


Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).


When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Life of tires
The service life of a tire is dependent upon
various factors including but not limited to:

Driving style


Tire pressure


Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure that the tires rotate in the direc-
tion specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.
Warning!
G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.

262 OperationTires and wheelsChecking tire inflation pressure
Correct the tire pressure only when tires
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and
cold tires as well as for various operating
conditions.Tire pressure changes by approximately
1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure where the
temperature is different from the outside
temperature.
Tire temperature and tire pressure are also
increased while driving, depending on the
driving speed and the tire load.Check the spare tire periodically for condi-
tion and inflation. Spare tires will age and
become worn over time even if never used,
and thus should be inspected and replaced
when necessary.Warning!
G
If the tire pressure repeatedly drops

check the tires for punctures from for-
eign objects


check to see whether air is leaking from
the valves or from around the rim
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed in the fuel filler flap.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.

264 OperationWinter driving
Winter drivingBefore the onset of winter have your vehi-
cle winterized at an authorized
Mercedes-Benz Center. This service in-
cludes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a pre-mixed windshield washer
solvent / antifreeze which is formulated
for below freezing temperatures
(page 357).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to ensure
that the engine can be started even at
low ambient temperatures.


Tire change. We recommend M+S rat-
ed radial-ply tires on all four wheels for
the winter season.
Winter tires
Always use winter tires at temperatures
below 39°F (4°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS and the ESP in win-
ter operation.
For safe handling, ensure that all mounted
winter tires are of the same make and have
the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-
tices are available from your tire dealer or
from any authorized Mercedes-Benz
Center.Warning!
G
Winter tires with a tread depth under 0.16 in
(4 mm) must be replaced. They are no long-
er suitable for winter operation.
Warning!
G
If you use your spare tire* when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.

309 Practical hints
Where will I find...?
In the case of a flat tire, you may tempo-
rarily use the Minispare wheel when ob-
serving the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km/h).


Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.


Do not operate vehicle with more than
one Minispare wheel mounted.
More information can be found in the
“Technical data” section (
page 345).Minispare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel or other
steel rims
!Wheel bolts2 must be used when
mounting the Minispare wheel. The use
of any wheel bolts other than wheel
bolts 2 for the Minispare will physically
damage the vehicle's brakes.
Warning!
G
Be sure to use the original length wheel
bolts when remounting the original wheel af-
ter it has been repaired.

324 Practical hintsFlat tire

Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Engage the steering wheel lock in the
straight ahead position and set the
parking brake.

Move the selector lever toP.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the Minispare wheel
In case of a flat tire, you may temporarily
use the spare wheel when observing the
following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km/h).


Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.


Do not operate the vehicle with more
than one spare wheel mounted.Preparing the vehicle
Prepare the vehicle as described on
(
page 324).

Take the wheel wrench and the jack
out of the trunk (
page 307).

Take the Minispare wheel out of the
trunk (
page 307).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks on the downhill side
blocking both wheels of the other axle.
Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The spare wheel should only be used tempo-
rarily, and should be replaced with a regular
road wheel as quickly as possible.
