Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving

Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Driving and operating141Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Notice
If AdBlue must be refilled at very low
temperatures, the refilling of AdBlue may not be detected by the system.
In this case, park the vehicle in a
space with a higher ambient
temperature until AdBlue is
liquefied.
Notice
If engine starting is prohibited due to low AdBlue level, we recommend
refilling the tank completely or with a
volume of at least ten litres of AdBlue (depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than ten litres), otherwise the system may not detect a refill.
Notice
When unscrewing the protective cap from the filler neck, ammonia fumes
may emerge. Do not inhale as the fumes have a pungent smell. The
fumes are not harmful by inhalation.
The vehicle must be parked on a level surface.
The filler neck for AdBlue is located
behind the fuel filler flap, located on
the left-hand side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the left- hand door is opened.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.
Capacities 3 215.

In case of incorrect refilling, do not switch on ignition. Seek the
assistance of a workshop
immediately.
4. Fully insert the pump nozzle into the filler neck and switch it on.
5. When refilling is complete, mount the protective cap and turn
clockwise until it engages.
6. Close fuel filler flap and left-hand door.
AdBlue canister Notice
Only use the designated AdBlue
canisters for refilling, to prevent a
topping-up of too much AdBlue.
Additionally, the fumes in the tank
are captured in the canister and do
not emerge.
Notice
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Open left-hand door and pull fuel filler flap to open.
3. Unscrew protective capanticlockwise from the filler neck.

144Driving and operatingCaution
It is inadvisable to drive with hand
resting on the selector lever.
Upshift 3 97.
Stop-start system 3 133.
Brakes
The brake system comprises two independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
If control indicator R illuminates in
the instrument cluster while driving
and a corresponding message
appears in the Driver Information
Centre 3 100, there is a fault in the
braking system. Seek the assistance
of a workshop immediately.Control indicator R 3 96.
Vehicle messages 3 101.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off, the system performs a self-test which may be audible.
Control indicator u 3 97.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates while
146Driving and operatingfor a further two seconds. The brakesrelease automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system 3 133.
Ride control systems
Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding message also appears in the Driver
Information Centre 3 100.
When TC is active b flashes.9 Warning
