278 OperationDriving instructionsTire traction
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
temperatures are close to the freezing
point.Mercedes-Benz recommends M+S rated
radial-ply tires with a minimum tread depth
of approximately
1/6in (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 as compared with sum-
mer tires.
Stopping distance, however, is still consid-
erably greater than when the road is not
covered with snow or ice. Exercise appro-
priate caution.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme 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.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or
personal injury and possible death, for you
and for others.

Warning!
G
Manually closing the retractable hardtop is a
complicated and technically demanding pro-
cedure and should only be performed by an
authorized Mercedes-Benz Center or quali-
fied technician. Attempting to manually
close the retractable hardtop may cause
damage to the retractable hardtop and/or
personal injury.
Warning!
G
To prevent possible accidents, drive the ve-
hicle only with the retractable hardtop either
completely closed and locked, or fully low-
ered into its storage compartment.

395 Practical hints
Flat tire
Lowering the vehicle
Lower vehicle by turning the crank
counterclockwise until vehicle is rest-
ing fully on its own weight.

Remove the jack.
1-5 Wheel bolts

Tighten the five wheel bolts evenly in
the direction of the arrow, following the
diagonal sequence illustrated
(1to5), until all bolts are tight.
Observe a tightening torque of
80 lb-ft (110 Nm).

Fully collapse the jack.

Place the vehicle tool kit, electric air
pump, and the jack back in the storage
compartment under the trunk floor.

Wrap the damaged wheel in the protec-
tive sheet provided with the spare
wheel and put the wheel in the trunk.
Warning!
G
Inflate the collapsible tire using the electric
pump (
page 393) before
lowering the ve-
hicle.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
80 lb-ft (110 Nm).iThe flat tire may be transported in the
trunk when the retractable hardtop is
closed.
