Notes on techhnical data

You should have all work on electrical

and electronic components carried out

at a qualiꢀed specialist workshop.

When operating two-way radios in the

vehicle, always connect them to the low-

reꢁection exterior antenna.

WARNING Risk of accident due to

improper operation of two-way radios

NOTE Invalidation of the operating permit

due to failure to comply with the instruc-

tions for installation and use

If you use two-way radios in the vehicle

improperly, their electromagnetic radiation

can disrupt the vehicle's electronics. This is

the case in the following situations, in particu-

lar:

The data stated only applies to vehicles with

standard equipment. You can obtain further infor-

mation from an authorized Mercedes-Benz Cen-

ter.

The operating permit may be invalidated if the

instructions for installation and use of two-way

radios are not observed.

#

Only use approved frequency bands.

R

The two-way radio is not connected to an

exterior antenna.

#

Observe the maximum permissible out-

put power in these frequency bands.

R

The exterior antenna is installed incor-

rectly or is not a low-reꢁection antenna.

Notes on installing two-way radios

This could jeopardize the operating safety of

the vehicle.

&

WARNING Risk of accident due to

improper work on two-way radios

#

Have the low-reꢁection exterior antenna

installed at a qualiꢀed specialist work-

shop.

If two-way radios are manipulated or retroꢀt-

ted incorrectly, the electromagnetic radiation

from the two-way radios can interfere with the

vehicle electronics and jeopardize the operat-

ing safety of the vehicle.

If you have accidentally refueled with the

wrong fuel:

Impairment of the longevity and performance

of the engine.

Note the instructions about operating ꢁuids

(/ page 328).

Do not switch on the vehicle.

If unleaded premium grade gasoline is unavail-

able and you have to refuel using unleaded

regular gasoline:

#

Consult a qualiꢀed specialist workshop.

*

NOTE Damage caused by the wrong fuel

If the available fuel is not suꢄciently low in sulfur,

this can produce unpleasant odors.

Even small amounts of the wrong fuel could

result in damage to the fuel system, the

engine and the emission control system.

#

Only ꢀll the fuel tank to half full with

unleaded regular gasoline and reꢀll as

soon as possible with unleaded premium

grade gasoline.

Only refuel with fuel that has at least the octane

number speciꢀed in the information label in the

fuel ꢀller ꢁap. Otherwise, engine output can be

reduced and fuel consumption increased.

#

Only refuel with low-sulfur spark-ignition

engine fuel.

#

Do not drive at the maximum design

speed.

For maximum engine output: Only refuel using

premium-grade unleaded gasoline with at least

91 AKI/95 RON.

This fuel may contain up to 10% ethanol by vol-

ume. Your vehicle is suitable for use with E10

fuel.

#

Avoid sudden acceleration and engine

speeds over 3000 rpm.

If the recommended fuel is not available, you may

also temporarily use regular unleaded gasoline

with an octane number of at least 87 AKI/

91 RON. This may reduce engine output and

increase fuel consumption.

Never refuel with one of the following fuels:

In some countries, the fuel available may not have

suꢄcient additives. Deposits could build up in the

fuel injection system as a result. In this case, in

consultation with an authorized Mercedes-Benz

Center, mix the fuel with the cleaning additive rec-

ommended by Mercedes-Benz. Observe the notes

and mixing ratios indicated on the tank.

WARNING ‑ Risk of ꢀre and injury from

antifreeze

&

WARNING Risk of an accident due to

vapor pockets forming in the brake system

* Recommended for the lowest possible fuel con-

sumption.

If antifreeze comes into contact with hot com-

ponent parts in the engine compartment, it

may ignite.

The brake ꢁuid constantly absorbs moisture

from the air. This lowers the boiling point of

the brake ꢁuid. If the boiling point is too low,

vapor pockets may form in the brake system

when the brakes are applied hard.

To achieve the lowest possible fuel consumption,

it is recommended to use the engine oil speciꢀca-

tions marked in the table for the lowest SAE vis-

cosity class. Observe any possible restrictions of

the approved SAE viscosity classes.

#

Allow the engine to cool down before

adding antifreeze.

#

Make sure that no antifreeze spills out

next to the ꢀller opening.

This causes the braking eꢃect to be impaired.

#

Have the brake ꢁuid renewed at the

speciꢀed intervals.

#

Thoroughly clean oꢃ any antifreeze from

component parts before starting the

vehicle.

Only use coolant that has been premixed
