Warning!G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road, and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
vehicle is covering a distance of
44 feet (approximately 14 m) every second.

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.

Remove unnecessary loads.

Allow engine to warm up under low
load use.

Avoid frequent acceleration and decel-
eration.

Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the Maintenance System. Contact
an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly area.
Drinking and drivingPedals
Warning!G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal ac-
cident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
and injury.

442 Technical data
Rims and tires
!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
ABS or 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:

MO = Mercedes-Benz Original equipment
tires
AMG vehicles:
Does not apply to all approved tires on AMG
vehicles. For information on tested and
approved tires for AMG vehicles, contact an
authorized Mercedes-Benz Center.

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.
iFor information on driving with MOExtended
tires, see “MOExtended system*” (
page 421).
!Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as

poor handling characteristics

increased noise

increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit
dimensional variations and different tire defor-
mation characteristics that could cause them to
come into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may be
the result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire
inflation pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire inflation pressure information for driving at
high speeds (
page 313) or for vehicle loads
less than the maximum loaded vehicle condition
(
page 313). If such information is provided, it
can be found on the placard located on the in-
side of the fuel filler flap.The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your
vehicles with winter tires. Winter tires are not
available as standard or optional factory
equipment, but can be purchased from an
authorized Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Performance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. Contact an authorized
Mercedes-Benz Center for more information.
