Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. Country-specific differen-
ces are possible. Note that your vehicle
may not be fitted with all features descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 22). Running-in notes
Important safety notes
New brake pads/brake pads and discs that
have been replaced only achieve optimum
braking effec tafter several hundred kilome-
tres of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedal. The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gea ringood time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain. After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
Additional running-in notes for AMG vehicles:
R
Do not drive at speeds above 140 km/h for
the first 1,500 km.
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Avoid driving off-road before the differen-
tial oil change at 3,000 km.
R Drive the vehicle mainly in drive program
Cfor the first 1,500 km.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle differen-
tial lock
To improve the protection of the differential,
change the oil after a run-in distance of
3,000 km. This oil change will lengthen the
service life of the differential. Have the oil
change carried out at a qualified specialist
workshop. Driving

AdBlue
®
Important notes on use To function properly, BlueTEC exhaust gas
aftertreatment 1
mus tbe operated with the
reducing agent AdBlue ®
.
When the supply of AdBlue ®
is almost used
up, the Refill AdBlue See Owner's Man‐
ual message is shown in the multifunction
display. Awarning tone also sounds.
If the Refill AdBlue No start in: .. km message is shown in the multifunction dis-
play, you can still driv ethe vehicle over the
distance shown. Awarning tone also sounds.
If the AdBlue ®
is no ttopped up, you will sub-
sequently be unable to start the engine.
After receiving the warning message, it is
preferable to fill the AdBlue ®
tank with
10 litres of AdBlue ®
.Int his way, you can
ensure that the AdBlue ®
supply lasts until the
next regular service date.
Further information about BlueTEC exhaust
gas aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Ben zService
Centre.
Topping up AdBlue ®!
Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatmen tsystem.
! In order to fill the AdBlue ®
tank, the vehi-
cle mus tbe parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven
surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatmen tcom-
ponents. !
Do not fill the AdBlue ®
container with a
pump nozzle.
! If there are steep gradients while driving
off-road, a sufficient filling level in the
AdBlue ®
tank must be ensured. Make sure
for this reason that there is a minimum fill
level of ten litres before driving off-road.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank.IfA dBlue®
is
added to the fuel tank, this can lead to
engine damage.
If you open the AdBlue ®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.

must not come into contact with
your skin, eyes or clothing.
R If you ge tAdBlue ®
in your eyes or on your
skin, rinse thoroughly without delay using
clear water.
R If AdBlue ®
has been swallowed, rinse your
mouth out immediately with plenty of clean
water, and drink plenty of water.
R Change immediately out of clothing conta-
minated with AdBlue ®
.
R If you notice allergic reactions, visit a doc-
tor immediately.
Keep AdBlue ®
away from children.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
If the outside temperature is below Ò11 †, it
may be difficult to top up. If AdBlue ®
is frozen
and there is an active warning indicator, top-
ping up may not be possible. Park the vehicle
in a warm place, e.g. in a garage, until
AdBlue ®
has become liquid again. Topping up
is then possible again. Alternatively, have the
AdBlue ®
tank refilled at a qualified specialist
workshop.
Have the AdBlue ®
supply checked at a quali-
fied specialist workshop before the following
types of journeys:
R journeys abroad outside of Europe
R off-road driving
X If necessary, have AdBlue ®
topped up.
Before a longer stay outside of Europe, con-
sult a qualified specialist workshop.

New brake pads/linings
New brake pads/brake pads and discs that
have been replaced only achieve optimum
braking effect after several hundred kilome-
tres of driving. Compensate for the reduced
braking effect by applying greate rforce to the
brake pedal.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety.
High-performance brake system for
AMG vehicles The high-performance brake system is
designed for high loads. This may lead to
noise when braking. This is dependent on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity.
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage (service life) that will be valid under
all circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your Mercedes-
Benz Service Centre.
Parking brake G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. This increa-
ses the risk of skidding and an accident. Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When you apply the parking brake to brake
the vehicle, the brake lamps do not light up.
If you drive on wet roads or dirt-covered sur-
faces, road salt and/or dirt could get into the
parking brake.
In order to prevent corrosion and a reduction
in the braking power of the parking brake,
observe the following:
R pull the parking brake upwards with the
release button depressed from time to time
before beginning the journey
(Y page 164).
R drive for approximately 100 m at a maxi-
mum speed of 20 km/h. Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. Driving on slippery surfaces
! If possible, do not let the drive wheels
spin. Otherwise, you could damage the
drive train.
