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. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions 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 23). Key
Important safety notes
G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key or with KEY-
LESS-GO, the double lock function is activa-
ted as standard. It is then not possible to open
the doors from inside the vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people requiring special assistance. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion sensor before
you lock the vehicle. The doors can then be
opened from the inside after the vehicle has
been locked from the outside. G
WARNING
If children are left unsupervised in the vehicle,
they could: R
open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. G
WARNING
If a key ring is too heavy or too large, the
weight acting on the key could cause it to turn
in the ignition lock or catch on the steering
wheel. This could cause the engine to be
switched off suddenly. You may lose control
of the vehicle and cause an accident. Do not
attach any heavy or large key rings to the key
that is inserted in the ignition.
R Do not keep the key:
-with electronic devices, e.g. a mobile
phone or another key
- with metallic objects, e.g. coins or metal
foil
- inside metallic objects, e.g. a metal case
This can affect the key's functionality.
Keep the key away from strong magnetic
fields. Otherwise, the remote control function
could be affected. 76

Problems with the transmission
Problem Possible causes/consequences and
M Solutions
The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist work-
shop immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into secondgear and reverse gear.
X Stop.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least ten seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
X Have the transmission checked at a qualified specialist work-
shop immediately. Releasing the parking lock manually
! Do not use any sharp-edged objects to
remove the selector lever gaiter from the
centre console. This could damage the
selector lever gaiter. X
Apply the parking brake.
X Prise out selector lever gaiter :with a flat,
blunt object (e.g. a screwdriver wrapped in cloth) from the right-hand edge. Pull selec-
tor lever gaiter
:up and out.
X Press release button ;down and simul-
taneously move the selector lever out of
position P.
The selector lever can now be moved freely
until it is returned to position P.
In the event of an electrical fault, it is possible
to release the selector lever lock manually to
move it out of position P. This occurs if the
vehicle is towed away, for example. Refuelling
Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. Refuelling

Coasting (evaluation of total decelera-
tion)
The bar fills up: The bar depletes:
Drive with care,
keep your distance
from the vehicle
ahead and remove
your foot from the
accelerato
rpedal in
good time: the vehi-
cle can coast with-
out braking Frequent braking
i
An economical driving style depends in
particular on driving at moderate speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendations.
R drive in drive program E(vehicles with
automatic transmission).
i On long journeys at constan tspeed, such
as on the motorway, only the "Constant"
category bar changes.
i The ECO display sums up the driving
behaviour from the start to the end of the
journey. As a result, the bars change
dynamically at the start of the journey. Dur-
ing long journeys there are fewer changes.
For more dynamic changes, perfor maman-
ual reset.
For further informatio nonECO display, see
(Y page 234). Short journeys
! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This may lead to fuel
collecting in the engine oil and cause
engine failure. Therefore, if you frequently
drive short distances, you should take a 20 minute trip on a motorway or rural road at
least every 500km. Braking
Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or
select shift range 1,2or 3on vehicles with
automatic transmission.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to prevent the
vehicle from gaining speed. This relieves the
load on the brake syste mand prevents the
brakes from overheating and wearing too
quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave
your foo tonthe brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There
is a risk of an accident.
Never use the brake pedal as a footrest.Do
not simultaneously depress both the brake
pedal and the accelerato rpedal while driving. 180
