Gasoline additives

A major concern among engine
manufacturers is carbon build-up caused by
gasoline. Mercedes-Benz recommends only
the use of quality gasoline containing
additives that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives carbon deposits can
build up, especially on the intake valves and
in the combustion area, leading to engine
performance problems such as:
Warm-up hesitation
R
Unstable idle
R
Knocking/pinging
R
Misfire
R
Power loss
R
In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives, the
use of Mercedes-Benz approved additives is
recommended.
Contact an authorized Mercedes-Benz Center
or visit www.mbusa.com (USA only) for a
listing of approved products. Follow
directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
!
Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties.

AdBlue
®
AdBlue is a non-flammable, non-toxic,
colorless and odorless, water-soluble liquid.
®
! Only use AdBlue
ISO 22241. Do not blend with additives.
! Rinse surfaces that have come into
contact with AdBlue
with a moist cloth and cold water
immediately. If AdBlue
already, use cold water and a sponge.
®
AdBlue residues will crystallize and soil
the affected surfaces.
High ambient temperatures
®
If AdBlue in the reservoir heats up to above
122‡ (50†) for a long period of time, for
example due to direct sunlight, ammonia gas
vapors may escape when opening the
®
AdBlue tank.
G
Warning!
When opening the filler cap of the AdBlue
tank ammonia gas vapors may escape. Refill
®
AdBlue in a well ventilated area only.
Ammonia gas vapors have a pungent odor and
are particularly irritating for your skin,
mucous membranes, and eyes. Inhaling
ammonia gas vapors will cause burning eyes,
nose, and throat, as well as coughing and
watering eyes.
Low ambient temperatures
®
AdBlue freezes at a temperature of
approximately 12‡ (-11†). Your vehicle is
factory equipped with an AdBlue
system. The vehicle can thus be operated at
temperatures below 12‡ (-11†).
