MERCEDES-BENZ E CLASS WAGON 2023 Owners Manual

Never refuel using gasoline of an even lower RON.*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.

qInformation on additives in gasoline (vehicles
with gasoline engine)
Observe the notes on operating Ouids
(  page 366).*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 qualiNed specialist workshop
(e.g. an authorized 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.

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

SAE viscosity class in each case; observe possible restrictions of
the approved SAE viscosity classes)
To achieve the lowest possible fuel consumption, it is recommended to use the engine oil speciNca-
tions marked in the table with the lowest SAE vis-
cosity class. Possible restrictions of the approved SAE viscosity classes must be observed.

Notes on brake Ouid
Observe the notes on operating Ouids
(  page 366).
&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.370Technical data

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 47).If necessary, consult a qualiNed specialist workshop immediately.Front Passenger Airbag
