259 Operation
At the gas station
At the gas station
The fuel filler flap is located on the
right-hand side of the vehicle towards the
rear. Locking/unlocking the vehicle with
the remote control or the SmartKey with
KEYLESS-GO* automatically locks/un-
locks the fuel filler flap.

Remove the key from the starter
switch.

Open the fuel filler flap by pushing at
the point indicated by the arrow.
The fuel filler flap springs open.

Turn the fuel cap to the left and hold on
to it until possible pressure is released.

Take off the cap and set it in the recess
on the fuel filler flap.
To prevent fuel vapors from escaping
into the open air, fully insert filler noz-
zle unit.

Only fill your tank until the filler nozzle
unit cuts out – do not top up or over-
fill.

Replace the fuel cap by turning it to the
right.
You will hear when the fuel cap is tight-
ened.

Close the fuel filler flap.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials. Never allow sparks,
flame or smoking materials near gasoline!
Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.

Tire inflation pressure
More information on tire inflation pressure
can be found in the "Operation" section
(
page 269).
iUse only 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.iLeaving the engine running and the fuel
cap open can cause the ?lamp to
illuminate.

271 Operation
Tires and wheels
Activating the tire inflation pressure
monitor
You must activate the tire inflation pres-
sure monitor in the following cases:

If you have changed the tire pressure


If you have replaced the wheels or tires


If you have installed new wheels or
tires

Be sure that the tire pressure is cor-
rectly set.

Press the ÿ button on the steering
wheel repeatedly until the standard dis-
play menu appears (
page 126).

Press the kbutton until the infla-
tion pressure of each tire appears in
the multifunction display.

Press the reset knob (
page 22).
The following message will appear in
the multifunction display:
Check current tire pressure?
.

Press the æ button for
Yes
.
The following message will appear in
the multifunction display:
Tire pressure
monitor activated
Press. display after
driving a few mins.
Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected in-
flation pressures. Always adjust tire inflation
pressure according to the label affixed on
the fuel filler cap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden loss
of pressure (e.g. tire puncture caused by a
foreign object). In this case bring the vehicle
to a halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.
iIf transporting a deflated road wheel or
additional wheel sensors in the vehicle,
the tire inflation pressure monitor
should not be reactivated until the de-
flated wheel or additional wheel sen-
sors have been removed from the
vehicle. Otherwise, the deflated wheel
or additional sensors could confuse the
tire inflation pressure monitor system
and cause it to malfunction.

293 Practical hints
What to do if …
Problem
Possible cause
Suggested solution
?
The yellow "CHECK ENGINE"
malfunction indicator lamp
comes on while driving.
There is a malfunction in:

The fuel injection system


The ignition system


The exhaust system


The fuel system
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.

Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the front left
area of the footwell next to the park-
ing brake.
Your gas tank is empty.

After refuelling, start the engine three
or four times in succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.
<
The red seat belt warning lamp
blinks for a brief period after
starting the engine.
The warning lamp reminds you to fasten seat
belts.

Fasten your seat belt.
W
The yellow fuel tank reserve
warning lamp lights up while
driving.
The fuel level has gone below the reserve
mark.
Gas cap not closed tight.

Refuel at the next gas station
(page 259).

361 Technical data
Rims and tires
Rims and tires
Use only 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
Same-sized tires
!Moreover, tires and rims not approved
by Mercedes-Benz may under load ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle can 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 fill-
er cap of the vehicle. The tire pressure
should only be adjusted on cold tires.
Follow the tire manufacturer’s mainte-
nance recommendation included with
the vehicle.

370 Technical dataFuels, coolants, lubricants etc.Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. You should have it replaced every
15 years or 150 000 miles (250 000 km),
whichever comes first.
Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level. To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze [equivalent to freeze
protection to approx. - 22°F (-30°C)]. If
you use a solution that is more than 55%
anticorrosion/antifreeze [freeze protec-
tion to approx. - 49°F (-45°C)], the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.

372 Technical dataFuels, coolants, lubricants etc.Windshield and headlamp washer system
Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The washer fluid reservoir has a capacity of
approx.:

7.4 US qt. (7 l) in vehicles with a head-
lamp cleaning system* or heated reser-
voir


4.8 US qt. (4.5 l) in vehicles without a
headlamp cleaning system

Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer
solvent / antifreeze, depending on am-
bient temperatures).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing, use
MB Windshield Washer Concentrate "S"
and water:


1 part "S" to 100 parts water
[40 ml "S" to 1 gallon (4 liters) water].
For temperatures below freezing use
MB Windshield Washer Concentrate "S"
and commercially available premixed
windshield washer solvent / antifreeze:


1 part "S" to 100 parts solvent
[40 ml "S" to 1 gallon (4 liters) solvent].
Warning
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may burn.
You can be seriously burned.
