Mercedes-Benz GL-Class 2011 Owners Manual - Manual (Page 370)

! Rinse surfaces that have come into
contact with AdBlue ® immediately with
water or remove AdBlue ® using a damp
cloth and cold water. If the AdBlue ® has
already crystallized, use a sponge and cold
water to clean it. AdBlue
® residues
crystallize after time and contaminate the
affected surfaces.
High outside temperatures
If AdBlue ® is heated to above 122 ‡ (50 †)
for an extended period of time, e.g. due to
direct sunlight on the AdBlue
® tank,
AdBlue ® may start to decompose. Ammonia
vapors develop as a result.
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 outside temperatures
AdBlue ® freezes at a temperature of
approximately 12 ‡(11 †). The vehicle is
equipped with an AdBlue
® preheating system
at the factory. Winter operation can thus be
guaranteed even at temperatures below
12 ‡(–11 †).
Additives
! Use only AdBlue ® complying with ISO
22241. Do not use any additives with
AdBlue
® and do not thin AdBlue ® with
water. This may destroy the BlueTEC
exhaust gas aftertreatment system.
Damage resulting from the use of additives
or water is not covered by the Mercedes-
Benz Limited Warranty.
Purity
Assuring the purity of AdBlue ® is particularly
important with respect to avoiding
malfunctions in the exhaust gas
aftertreatment system.
If AdBlue
® is pumped out of the AdBlue ® tank,
e.g. during repair work, it must not be
returned to the tank. The purity of the fluid
can no longer be guaranteed.
! Impurities in AdBlue ® , e.g. due to other
service products, cleaning agents or dust,
lead to increased emission values, system
malfunctions, catalytic converter damage
or damage to the BlueTEC system.
Engine oil
Points to remember
The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. For this reason, only use
engine oils and oil filters that are approved for
vehicles with a service system.
Contact an authorized Mercedes-Benz Center
or visit
http://www.mbusa.com (USA only)
for a list of approved engine oils and oil filters.
! Never use engine oil or an oil filter of a
specification 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 prescribed. Otherwise,
you may cause damage to the engine or
exhaust gas aftertreatment; this is not
covered by the Mercedes-Benz Limited
Warranty.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
Mercedes-Benz recommends MOBIL OIL.
The table shows which engines oil have been
approved for your vehicle.
