Additional air conditioning is supplied
to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
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 and the
air distribution to V.
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.

Adjustable air vents may be located inthe roof frame above the seats. Turn
adjuster to increase/decrease airflow
to the appropriate seat.
Fixed air vents Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.
Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended that the climate control system be checked annually, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
120Driving and operating
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and brake performance will be
maintained. Brake assist, however, is
not available 3 136.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed or the driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the brake vacuum is sufficient ● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See Climate control chapter for
further information 3 103.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 117.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
Driving and operating127indicator Õ illuminates continuously
together with A 3 85 and a warning
chime.
Requests to have the exhaust system
checked and finally the
announcement that an engine restart
with be prevented are displayed in the DIC.
Notice
These restrictions are a legal
requirement.
At an AdBlue range of approx.
680 miles, a warning message is
displayed in the DIC showing the
remaining distance the vehicle can
travel before engine restarts are
prevented. This warning message is
repeated approx. every 60 miles.
Seek the assistance of a workshop as
soon as possible.Version without level warnings in the Driver Information Centre (DIC)
When the Adblue gauge shows the
level is very low, control indicator Õ
first illuminates continuously, then as
Adblue level drops to a certain
amount Õ flashes for a few seconds
then illuminates continuously.
Refill the Adblue tank as soon as
possible. Refer to " Refilling AdBlue"
below.
Driving is possible without any
restrictions.
Engine power loss
As the Adblue level drops further,
control indicator Õ flashes for a few
seconds then illuminates
continuously, accompanied by a
warning chime and loss of engine
power.
Notice
These restrictions are a legal
requirement.
If AdBlue is not refilled before the tank
is empty, Õ flashes and after the next
engine restart the vehicle speed will
be limited to approx. 12 mph.
Refill immediately with at least
10 litres of AdBlue.High emission warnings
If the exhaust emission rises above a
certain value, control indicator Õ
illuminates together with A 3 85.
Consult a workshop as soon as
possible.
If the fault is not rectified within a
certain distance, Õ and A flash for
a few seconds then illuminate
continuously. Loss of engine power.

3. Unscrew protective capanticlockwise from the filler neck.
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 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.
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.
Depending on version, a
corresponding message may also
appear in the DIC 3 89.
134Driving and operatingInterruption of power supplyThe clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 188.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground
3 190.
Towing the vehicle 3 190.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.
Control indicator R 3 85.
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.
Control indicator u 3 86.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre (DIC), there is a fault in the ABS. The brake system
remains operational but without ABS
regulation.
