mended for your vehicle.
!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions:
ROnly fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and engine
speeds over 3,000 rpm.

CLA 250, CLA 250 Sport, CLA 250 4MATIC,
CLA 250 Sport 4MATIC: as a temporary meas-
ure, if the recommended fuel is not available,
you may also use regular unleaded gasoline with
an octane rating of 88 AKI/93 RON.
All other models: as a temporary measure, if
the recommended fuel is not available, you may also use regular unleaded gasoline with an
octane rating of 87 AKI/91 RON. This may
reduce engine performance and increase fuel
consumption. Avoid driving at full throttle and
sudden acceleration. Never refuel using gaso-
line with a lower AKI.
Information on refueling (
Ypage 138).
Additives
!Operating the engine with fuel additives
added later can lead to engine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran- ded fuels that have additives.
The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as a result. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Engine oil
General notes
!Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products (
Ypage 309).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main- tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
