Driving and operating151Driving hints
Control of the vehicle
Never coast with engine not
running
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a danger to yourself and others. All
systems function during an Autostop.
Stop-start system 3 154.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.Use only floor mats which fit properly
and are fixed by the retainers on the
driver's side.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 114.Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging of the vehicle battery.
Diesel particle filter 3 157.
Ignition switch positions Turn key:
Driving and operating1611. Continuously drive the vehiclefor 10 minutes making sure that
vehicle speed is always higher
than 20 km/h.
2. If AdBlue refill is detected successfully, AdBlue supply-
driven limitations will disappear.
If AdBlue refill is still not detected,
seek the assistance of a workshop.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue may not be
detected by the system. In this
event, park the vehicle in a space
with a higher ambient temperature
until AdBlue is liquefied.
Note
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 AdBlue tank should be filled
completely. This must be done if the
warning message regarding
prevention of an engine restart is
already displayed.The vehicle must be parked on a level surface.
The filler neck for AdBlue is located
behind the fuel filler flap, which is located at right rear side of the
vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked.
1. Remove key from ignition switch.
2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.
3. Release the fuel filler flap by pushing the flap 3 203.
4. Unscrew protective cap from the
filler neck.
5. Open AdBlue canister.
6. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
7. Lift the canister until it is empty, or
until the flow from the canister has stopped. This can take up to five
minutes.
8. Place the canister on the ground to empty the hose, wait 15
seconds.
9. Unscrew the hose from the filler neck.
10. Mount the protective cap and turn
clockwise until it engages.
Note
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before
AdBlue dries out.
166Driving and operatingBrakes
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 the brake pedal
is depressed firmly. Considerably
more force is needed 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.
Control indicator R 3 112.
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 3 113.
Adaptive brake light During full braking, all three brake
lights flash for the duration of ABS
control.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator R (manual parking
brake) or m (electrical parking
brake) must illuminate constantly.
