Auxiliary heater
Coolant heater The Eberspächer engine-
independent, fuel-powered coolant
heater provides rapid heating of the
engine coolant to enable heating of
the vehicle interior without the engine
running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.

120Driving and operatingthan 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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 the
vehicle battery.

Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
Caution
To ensure safe operation of the air
suspension system, do not exceed the maximum permissible gross
vehicle weight rating. Refer to
identification plate 3 204 or the
vehicle documents.
For further information on the air
suspension system, refer to the
operating instructions supplied.
Master switch
Caution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
Jump starting 3 193, Towing the
vehicle 3 195.
The master switch is located on the
door pillar.
Switch on to enable operation and
adjustment of the air suspension
system.
Driving and operating131Caution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do 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
adding a volume of at least 10 litres
of AdBlue when refilling. Avoid minor
top-ups (e.g. less than 5 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 filler flap located on the
right-hand side of the vehicle.
The filler flap can only be opened if the vehicle is unlocked and the right-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 3 224.
Filling station9 Danger
Follow the operating and safety
instructions of the filling station
when refilling Adblue.
1. Switch off engine and remove key
from ignition switch.
2. Pull filler flap to open.
3. Unscrew protective cap anticlockwise from the filler neck.
4. Fully insert the pump nozzle into the filler neck and switch it on.
132Driving and operating5. When refilling is complete, mountthe protective cap and turn
clockwise until it engages.
6. Close filler flap and right-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. Pull filler flap to open.
3. Unscrew protective cap anticlockwise from the filler neck.
4. Open AdBlue canister.
5. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
6. Lift the canister until it is empty.
7. Unscrew the hose from the filler neck.
8. Mount the protective cap and turn
clockwise until it engages.
9. Close filler flap and right-hand door.
Notice
Dispose of AdBlue canister and
hose according to environmental
requirements.
Notice
Let the vehicle idle for 10 seconds to
allow the system to detect the
AdBlue refill.
Failure to observe this procedure will result in the system only recognising
the AdBlue refill after 20 minutes of
driving.
If the AdBlue refill is detected
successfully, AdBlue level warnings
will disappear.
If the AdBlue refill is not detected
some time after running the engine,
seek the assistance of a workshop.
Filler cap
Only use genuine filler caps. Adblue
tank has a special filler cap.
Fault
If the system detects an operating
fault, control indicator Õ illuminates
together with A and a warning
chime. Seek the assistance of a
workshop immediately.
