Transfer case
!
Performance tests may only be carried out
on a 2-axle dynamometer. The brake system
or transfer case could otherwise be damaged.
Contact a qualified specialist workshop for a
performance test.
!Because ESP®is an automatic system, the
engine and ignition must be switched off
(SmartKey in position 0or 1or Start/Stop
button in position 0or 1) when the electric
parking brake is being tested on a brake dyna-
mometer (maximum 10 seconds).
Braking triggered automatically by ESP
®may
seriously damage the brake system.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as
doing so will damage the transmission.

DEF (BlueTEC vehicles only)
General notes
To function properly, BlueTEC exhaust gas after-
treatment must be operated with the reducing
agent DEF. Adding DEF is one of the tasks per-
formed during maintenance. Under normal operating conditions, a tank of DEF lasts until
the next service due date.
When the supply of DEF is almost used up, the
Check Additive See Operator's Manualmessage is shown in the multifunction display.
If you drive the vehicle faster than 10 mph
(16 km/h), the
Check Additive See Opera‐
142Refueling
Driving and parking

tor's Manualmessage goes out after approx-
imately one minute.
When the DEF supply drops to a minimum, the
Remaining Starts: 16
message is shown in
the multifunction display.
If the Remaining Starts: 16
message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is not
refilled, you will subsequently be unable to
start the engine.
XAdd at least 1 gal (3.8 l)of DEF.
XSwitch on the ignition for at least 60 seconds.
XStart the engine.
iHave the DEF tank refilled at a qualified spe-
cialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. You can
obtain further information from an authorized
Mercedes-Benz Center or, if necessary, contact
Roadside Assistance (
Ypage 26).
If the outside temperature is below 12 ‡(Ò11 †)
it may be difficult to top up. If DEF is frozen and
there is an active warning indicator, it may not
be possible to add DEF. Park the vehicle in a
warmer place, e.g. in a garage, until DEF has
become fluid again. It will then be possible to
add DEF again. Alternatively, have the DEF tank
refilled at a qualified specialist workshop.
Further information about BlueTEC exhaust gas aftertreatment and DEF is available at any
authorized Mercedes-Benz Center.
Important safety notes
DEF is a water-soluble fluid for the exhaust gas
aftertreatment of diesel engines. It is:
Rnot poisonous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small
amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence a burning sensation in your eyes, nose and
throat. Coughing and watering of the eyes are
possible.
Do not inhale ammonia vapors. Fill the DEF tank
only in well-ventilated areas. DEF must not come into contact with your skin,
eyes or clothing and must not be swallowed.
Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the following:
RRinse DEF from your skin immediately with
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with clean
water. Seek medical assistance without
delay.
RIf DEF has been swallowed, rinse your mouth
out immediately. Drink plenty of water. Seek
medical assistance without delay.
RChange out of clothing contaminated with
DEF immediately.
!Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
!The vehicle must be parked on level ground
to fill the DEF tank. The DEF tank can only be
filled as intended with the vehicle parked on a
level surface. This avoids false level readings.
Filling the tank is not permitted if the vehicle
is not parked on a level surface. There is a
danger of overfil
ling, which could result in
damage to components of the BlueTEC
exhaust gas aftertreatment.
!Rinse surfaces that have come into contact
with DEF immediately with water or remove
DEF using a damp cloth and cold water. If the
DEF has already crystallized, use a sponge
and cold water to clean it. DEF residues crys-
tallize after time and contaminate the affec-
ted surfaces.
!DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to the
fuel tank, this can lead to engine damage.
For further information on DEF, see
(
Ypage 355).

overfilling. DEF may leak if overfilled. Mercedes-
Benz offers a special disposable hose with over-
fill protection. You can obtain this from any
authorized Mercedes-Benz Center. DEF is avail-
able in a variety of containers and receptacles.
Only use the disposable hose with the
Mercedes-Benz DEF refill canisters.
DEF refill bottle
!Only screw on the DEF refill bottle hand-
tight. Otherwise, the thread of the DEF refill
bottle could be damaged and DEF could leak
out.
XUnscrew the protective cap from DEF refill
bottle :.
XPlace DEF refill bottle :on the filler neck as
shown and screw it on clockwise until hand-
tight.
XPress DEF refill bottle :towards the filler
neck.
The DEF tank is filled. This may take up to one
minute.
iWhen DEF refill bottle :is no longer
pressed, filling stops and the bottle may be
taken off again after being only partially emp-
tied.
XRelease DEF refill bottle :.
XTurn DEF refill bottle:counter-clockwise
and remove it.
XScrew the protective cap onto DEF refill bot-
tle : again.
DEF refill canisters are available at many gas
stations or at a qualified specialist workshop.
Refill bottles without a threaded cap do not pro-
vide overfill protection. DEF may leak if overfil-
led. Mercedes Benz offers special refill bottles
with a threaded seal. These are available at any
authorized Mercedes-Benz Center.

Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found in the Maintenance Booklet.
