vehicle (e.g. smoke or fire in the vehicle,
vehicle in a dangerous road location), please
do not wait for voice contact after you have
pressed the emergency button. Carefully
leave the vehicle and move to a safe loca-
tion. The Response Center will automatically
contact local emergency officials with the
vehicle’s approximate location if they
receive an automatic SOS signal and cannot
make voice contact with the vehicle occu-
pants.
279 Operation
Tires and wheels
Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:
Driving style
Tire pressure
Distance driven
Direction of rotation
Unidirectional tires offer added advan-
tages, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of tire rotation.
Checking tire inflation pressure
Correct the tire pressure only when tires
are cold.
Regularly check your tire pressure at
intervals of no more than 14 days.
If the tires are warm you should only
correct the tire pressure if it is too low for
current operating conditions.
A table on the fuel filler flap lists the
specified tire inflation pressures for warm
and cold tires as well as for various
operating conditions.
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.
Warning!
G
If the tire pressure drops repeatedly:
Check the tires for punctures from
foreign objects.
Check to see whether air is leaking from
the valves or from around the rim.
280 OperationTires and wheels
Tire pressure changes by approx. 1.5 psi
(0.1 bar) per 18°F (10°C) of air tempera-
ture change. Keep this in mind when
checking tire pressure where the tempera-
ture is different from the outside tempera-
ture.
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
b e c o m e w o r n o v e r t i m e e v e n i f n e v e r u s e d ,
and thus should be inspected and replaced
when necessary.
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. Overinflated tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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 indi-
cated by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
282 OperationWinter drivingBefore the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:
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 premixed windshield washer
solvent/antifreeze which is formulated
for below freezing temperatures
(page 381).
Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.
Tire change. Mercedes-Benz recom-
mends 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.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum
effectiveness of the ABS, ESP and 4MATIC
in winter operation.
For safe handling, make sure 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
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.Warning!
G
Winter tires with a tread depth under
1/6in
(4 mm) must be replaced. They are no
longer 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.
325 Practical hints
Where will I find ...?
In the case of a flat tire, you may
temporarily use the Minispare 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
replaced as appropriate.
Do not operate vehicle with more than
one Minispare wheel mounted.
For more information, see “Rims and Tires”
(
page 367).Minispare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel or other
steel rims (located in vehicle tool kit)
!Wheel bolts2 must be used when
mounting the Minispare wheel or other
steel rims. The use of any wheel bolts
other than wheel bolts2 for the
Minispare wheel or other steel rims will
physically damage the vehicle’s
brakes.Warning!
G
Make sure to use the original length wheel
bolts when remounting the original wheel
after it has been repaired.
342 Practical hintsFlat tire
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flasher
(page 113).
Turn the steering wheel so that the
front wheels are in the straight ahead
position.
Set the parking brake (
page 55).
Move the gear selector lever toP.
Turn off the engine (
page 57).
Remove the SmartKey from the starter
switch.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the Minispare wheel
Preparing the vehicle
Prepare the vehicle as described on
(page 342).
Take the wheel wrench, the wheel
bolts, and the jack out of the storage
compartment behind the left trim panel
(page 321).
Take the Minispare wheel out of the
storage compartment underneath the
cargo compartment floor
(page 324).
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. Adapt your driving style accord-
ingly.
The Minispare wheel is for temporary use
only. When driving with spare wheel
mounted, ensure proper tire pressure and
do not exceed a vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the Minispare
wheel replaced with a regular road wheel.
Never operate the vehicle with more than
one Minispare wheel mounted.
iOpen door only when conditions are
safe to do so.
