MERCEDES-BENZ E CLASS COUPE 2023 Owners Manual

Change immediately out of clothing thathas come into contact with fuel.Flexible-fuel vehicles can be refueled with the fol-lowing fuel types:
= premium-grade unleaded gasoline
= E85 fuel
= a mixture of E85 fuel and premium-grade
unleaded gasoline
Flexible-fuel vehicles can be identiNed by the
Ethanol up to E85 sticker on the inside of the fuel
Nller Oap.
Depending on the country, the fuels you can use in your vehicle may diMer from the information in
the Operator\bs Manual. The fuels that have been
approved for your vehicle can be found on the
instruction label on the inside of the fuel Nller Oap.Fuel

q Information on fuel quality for vehicles with gas-
oline engine
Observe the notes on operating Ouids
(  page 347).
*NOTE Damage caused by the wrong fuel
Even small amounts of the wrong fuel could
result in damage to the fuel system, the
engine and the emission control system.
Only refuel with low-sulfur spark-ignition
engine fuel.
This fuel may contain up to 10% ethanol by vol- ume. Your vehicle is suitable for use with E10 fuel.
Never refuel with one of the following fuels: = diesel
= Gasoline with more than 10% ethanol by
volume, e.g. E15, E85, E100
= Gasoline with more than 3% methanol by
volume, e.g. M15, M30, M85, M100
= Gasoline with additives containing metal
If you have accidentally refueled with the
wrong fuel:Do not switch on the vehicle.Consult a qualiNed specialist workshop.
If the available fuel is not suPciently low in sulfur,
it may produce unpleasant odors.
Refuel using only fuel that has at least the octane number speciNed on the information label on the
fuel Nller Oap ( page 161).
For maximum engine output: refuel using only pre-
mium-grade unleaded gasoline with an octane
number of at least 91 AKI/95 RON.
As a temporary measure, if the recommended fuel is not available, you may also refuel with regular
unleaded gasoline of at least 87 AKI/91 RON. This may reduce engine output and increase fuelconsumption.
Never refuel using gasoline of an even lower RON.
Technical data349

*NOTE Premature engine wear through
unleaded regular gasoline
Impairment of the longevity and performance
of the engine.
If unleaded premium grade gasoline is unavail- able and you have to refuel using unleaded
regular gasoline:
Only Nll the fuel tank to half full with
unleaded regular gasoline and reNll as
soon as possible with unleaded premium
grade gasoline.Do not drive at the maximum design speed.Avoid sudden acceleration and engine
speeds over 3000 rpm.
Further information on fuel is available at the fol- lowing locations:
= At a gas station
= At a qualiNed specialist workshop

qInformation on additives in gasoline (vehicles
with gasoline engine)
Observe the notes on operating Ouids
(  page 347).*NOTE Damage from use of unsuitable
additives
Even small amounts of the wrong additive may
lead to malfunctions occurring.
Only add cleaning additives recommen-
ded by Mercedes-Benz to the fuel.
Mercedes-Benz recommends that you use brand-
name fuels with additives.
In some countries, the fuel available may not have
suPcient additives. Deposits could build up in the
fuel injection system as a result. In this case, in consultation with a Mercedes-Benz Service Cen-ter, mix the fuel with the cleaning additive recom-
mended by Mercedes-Benz. Observe the notes and mixing ratios indicated on the tank.

rect oil Nlter, incorrect oil or additivesDo not use engine oils or oil Nlters other
than those which meet the speciNcations
necessary for the prescribed service
intervals.Do not alter the engine oil or oil Nlter in
order to achieve longer change intervals than prescribed.Do not use additives.Have the engine oil changed aser the
prescribed intervals.Mercedes-Benz recommends having the oil
changed at a qualiNed specialist workshop.

Notes on brake Ouid
Observe the notes on operating Ouids
(  page 347).
&WARNING Risk of an accident due to
vapor pockets forming in the brake system
The brake Ouid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake Ouid. If the boiling point is too low,
vapor pockets may form in the brake system when the brakes are applied hard.
This causes the braking eMect to be impaired.
Have the brake Ouid renewed at the
speciNed intervals.Technical data351

Have the brake Ouid regularly replaced at a quali-
Ned specialist workshop.
Only use a brake Ouid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval 331.0.

ual*The front passenger air bag and the front passenger knee air bag have been disabled even though an adult or a person of adult build is on the front passenger seat. If additional forces are applied to the seat, the weight the system detects
may be too low.&WARNING Risk of injury or fatal injury due to a disabled front passenger airbag
If the front passenger airbag is disabled, the front passenger airbag will not be deployed in the event of an accident
and cannot perform its intended protective function.
A person in the front passenger seat could then, for example, come into contact with the vehicle\bs interior, espe-
cially if the person is sitting too close to the cockpit.
Make sure, both before and during the journey, that the status of the front passenger airbag is correct.Stop the vehicle immediately in accordance with the traPc conditions.Make sure that no objects are trapped under the front passenger seat.Check the status of the automatic front passenger air bag shutoM ( page 48).If necessary, consult a qualiNed specialist workshop immediately.Front Passenger Airbag
