Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures.
Remove unnecessary loads.
Remove roof rack when not in use.
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 Service
Booklet and as required by the FSS.
Contact your authorized
Mercedes-Benz Center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
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 judgement.
The possibility of a serious or even fatal
accident 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
Keep driver’s foot area clear at all times.
Objects stored in this area may impair pedal
movement.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.

250 OperationAt the gas station
Open fuel filler flap by pushing at the
point indicated by the arrow.
The fuel filler flap springs open.
Turn fuel cap to the left and hold on to
it until possible pressure is released.
Take off cap and set it in the recess on
fuel filler flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.
Only fill your tank until the filler nozzle
unit cuts out – do not top up or overfill.
Replace fuel cap by turning it to the
right.
You will hear when fuel cap is
tightened.
Close fuel filler flap.Warning!
G
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel
pump nozzle, which could cause personal
injury.
iOnly use premium unleaded gasoline
with a minimum Posted Octane Rating
of 91 (average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump.
More information on gasoline can be
found in the Factory Approved Service
Products pamphlet.
Flexible Fuel Vehicles are identified by
a label reading Premium gasoline or
E85 only! on fuel filler flap.
For more information, see “Flexible
Fuel Vehicles” (
page 354).
iLeaving the engine running and the fuel
cap open can cause the? malfunc-
tion indicator lamp to illuminate.
For more information, see “Practical
hints” (
page 276).

261 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.
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.
Page 262 of 400
262 OperationTires and wheelsTire 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
become worn over time even if never used,
and thus should be inspected and replaced
when necessary.
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3 000
to 6 000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the
degree of tire wear. The same direction of
tire rotation must be retained.Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and
ensure proper tire inflation pressure.
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.Warning!
G
Rotate front and rear wheels only if they are
of the same size.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
80 lb-ft (110 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

342 Technical dataRims and Tires
Rims and TiresOnly use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims 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 deformation characteris-
tics 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 tire inflation
pressure table is located on the fuel
filler flap of the vehicle. The tire pres-
sure should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

Premium unleaded gasoline
Fuel requirements
Only use premium unleaded meeting
ASTM standard D 439:
The octane number (posted at the
p um p) m us t be 91 mi n. It i s an a vera ge
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M)/2. This is also known as the
ANTI-KNOCK INDEX.Unleaded gasoline containing oxygenates
such as Ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of Methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of Ethanol and Methanol is
not allowed. Gasohol, which contains 10%
Ethanol and 90% unleaded gasoline, can
be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
!To maintain the engine’s durability and
performance, premium unleaded gaso-
l i n e m u s t b e u s e d . I f p r e m i u m u n l e a d e d
is not available and low octane fuel is
used, follow these precautions:
Have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible.
Avoid full throttle driving and abrupt
acceleration.
Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded
with a light load such as two
persons and no luggage.
Do not exceed
2/3 of maximum
accelerator pedal position if the
vehicle is fully loaded or operating
in mountainous terrain.
iFlexible Fuel Vehicles (identified by a
label reading Premium gasoline or
E85 only! are designed to operate on
premium unleaded gasoline or Ethanol
fuel (E85) or any mixture of these two.
See notes on Flexible Fuel Vehicles
(page 354).
