AdBlue

(vehicles with a diesel engine only)

▌Notes on AdBlue

Observe the notes on operating uids

(/ page 725).

AdBlue

is a water-soluble uid for the NOx

exhaust gas aertreatment of diesel engines.

It may be improper or punishable in some coun-

tries to operate a vehicle that uses no AdBlue

one that does not comply with the specications

of this Owner's Manual.

NOTE Malfunctions due to the dilution of

AdBlue

or the use of additive-enhanced

AdBlue

The function of the NOx exhaust gas aer-

treatment can be impaired by the use of

unsuitable denoxication agents.

Only use AdBlue

in accordance with

ISO 22241.

Do not dilute AdBlue

with water.

Do not use additive-enhanced AdBlue

NOTE Damage and malfunctions due to

impurities in AdBlue

Consequences of impurities in AdBlue

increased emission values

damage to the catalytic converter

NOx exhaust gas aertreatment malfunc-

tions

Avoid impurities in AdBlue

AdBlue

residues crystallise aer a period of

time, and contaminate the surfaces with which

they come into contact. Clean the dirty surfaces

with water as soon as possible.

When you open the AdBlue

tank, small amounts

of ammonia vapour may escape. Do not inhale

any ammonia vapours that may be released. Only

ll the AdBlue

tank in well-ventilated areas.

AdBlue

consumption

The average AdBlue

consumption is between 1%

and 5% of fuel consumption. Like fuel consump-

tion, AdBlue

consumption is highly dependent

upon driving style and operating conditions. For

this reason, your vehicle's actual consumption g-

ures in day-to-day operating conditions may dier

from the average consumption gures calculated.

The frequency at which you will have to top up

AdBlue

will also vary. Have the AdBlue

supply

checked at a qualied specialist workshop before

making journeys outside Europe. Before a longer

stay outside Europe, consult a qualied specialist

workshop.

Notes on brake uid

Observe the notes on operating uids

(/ page 725).

WARNING Risk of an accident due to

vapour pockets forming in the brake sys-

tem

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,

vapour pockets may form in the brake system

when the brakes are applied hard.

This impairs the braking eect.

Have the brake uid renewed at the

specied intervals.

Have the brake uid regularly replaced at a quali-

ed specialist workshop.

Only use a brake uid approved by Mercedes-

Benz according to MB-Freigabe or MB-Approval

331.0.
