tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified
government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance. G
Warning!
If ice has formed on the road, tire traction will
be
substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperature is close to the freezing point.
Mercedes-Benz recommends winter tires
(Y page 251) with a minimum tread depth of
approximately 1
/ 6 in (4 mm) on all four wheels
for the winter season to ensure normal
balanced handling characteristics. On
packed snow, they can reduce your stopping
distance compared to summer tires.
Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
! Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
Temperature G
Warning!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause excessive heat build-up and possible tire
failure.
The temperature grades are A (the highest),
B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law. Rotating tires
G
Warning!
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires
(different tire dimensions front vs. rear),
tire rotation is not possible. G
Warning!
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft
(150 Nm).
Only use genuine Mercedes-Benz wheel bolts
specified for your vehicle’s rims.
Tire rotation can be performed on vehicles
with tires of the same dimension all around.
If your vehicle is equipped with tires of the
same dimension all around, tires can be
rotated, observing a front-to-rear rotation
pattern that will maintain the intended
rotation (spinning) direction of the tire
(Y page 240).
In some cases, such as when your vehicle is
equipped with mixed-size tires (different tire Tires and wheels

X
Tighten the five wheel bolts evenly,
following the diagonal sequence illustrated
(: to A), until all bolts are tight. Observe
a tightening torque of 110 lb-ft (150 Nm). G
Warning!
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
X Fully collapse the jack to storage position,
see ( Y page 272).
X Store the jack and the other vehicle tools
in the designated storage space.
For information on storing the spare wheel
after it has been replaced by a regular road
wheel, see ( Y page 272).
i The damaged road wheel cannot be
stored in the spare wheel well under the
cargo compartment floor. It should be
transported in the cargo compartment
wrapped in a protective wrap.
i USA only:
Do not restart the tire inflation pressure
monitor until a full size wheel/tire with
functioning sensor has been placed back
into service on the vehicle. MOExtended system
The MOExtended system allows you to
continue driving your vehicle even if there is
a total loss of pressure in one or more tires. You may only use the MOExtended system in
conjunction with the tire pressure loss
warning system (
Y page 231) or the
Advanced TPMS (Y page 232).
The maximum distance in emergency mode
depends on the vehicle’s load. It is 50 miles
(80 km) if the vehicle is partially loaded and
18 miles (30 km) if the vehicle is fully loaded.
The point at which the maximum driving
distance in emergency mode begins is when
the warning message appears in the
multifunction display indicating that there is
a loss of tire inflation pressure.
X Do not exceed the maximum speed of
50 mph (80 km/h). G
Warning!
In emergency mode, your vehicle’s driving
characteristics are diminished in such
situations as:
R driving around curves
R while braking
R while accelerating rapidly
Therefore, your driving style must be adapted
accordingly. Avoid abrupt steering and driving
maneuvers, as well as driving over obstacles
(road curbs, potholes, or off-road areas). This
is especially important if the vehicle is heavily
loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can be
significantly shorter or, if the vehicle is driven
cautiously, somewhat longer.
Do not continue driving in emergency mode if
R you notice knocking sounds
R the vehicle starts to shake
R smoke develops and you smell rubber
R ESP ®
is intervening continuously
R you notice tears on the tire sidewalls 330

Notes
! Only
use tires which have been tested and
approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are developed
to provide best possible performance in
conjunction with the driving safety systems
on your vehicle such as the ABS or the
ESP ®
. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO = Mercedes-Benz Original
equipment tires
R MOE
= Mercedes-Benz Original Extended
(tires with limited run-flat
characteristics) original equipment tires
Using tires other than those approved by
Mercedes-Benz may result in damage that
is not covered by the Mercedes-Benz
Limited Warranty.
For information on driving with MOExtended
tires, see the “Practical hints” section
(Y page 330).
