Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Boot lid cannot be opened or closed
Check whether the boot lid is blocked by an obstacle. The boot lid can be moved by hand. You will
need to use increased force for this.
The drive switches off automatically in order to prevent overheating if the boot lid is operated too
frequently in a short space of time. Until the drive has cooled down, the boot lid can be opened and
closed by hand using more force than usual.
When you tow a trailer, the electrical boot lid can only be opened and closed on the boot lid
⇒ Trailer towing .
The boot lid must be closed by hand if the 12-volt vehicle battery or fuse is disconnected or faulty.
All turn signals flash four times
The vehicle key used last is still in the vehicle.
Boot lid is stiff
At outside temperatures below freezing point, the opening mechanism cannot always lift the
partially opened boot lid automatically. In this case, guide the boot lid further up by hand.
Windows

Ensure that nobody obstructs the path of the window, especially if a window is being closed when
the roll-back function is not active.
The roll-back function does not prevent fingers or other body parts from being pressed against the
window frame and being injured.

The roll-back function is also activated if the windows are closed using the vehicle key for
convenience closing.
Troubleshooting
One-touch opening and closing does not work
One-touch opening and closing is deactivated if the 12-volt vehicle battery has been disconnected or
discharged while the windows were not fully closed. The function must then be reset:
Switch on the ignition.
Close all windows and doors.
Pull up the button for the respective window and hold it in this position for several seconds.
Release the button, then pull it up again and hold it in this position. The one-touch function is now
ready for operation again.
The one-touch function can be restored for individual windows or for several windows at the same
time.
Closing windows without roll-back function
Attempt to close the window again within a few seconds by holding the button. The roll-back
function will be deactivated for a small part of the path of the closing window.
If the closing procedure takes longer than several seconds, the roll-back function will be reactivated.

If the battery capacity is not sufficient for the side lights or parking light to remain switched on for
two hours, the 12-volt vehicle battery can be discharged to such an extent that it is no longer
possible to start the engine ⇒ .
In the case of standing times of more than two hours, the vehicle will detect a weak 12-volt vehicle
battery and switch off the side lights or parking light so that the engine can still be started.

WARNING
Accidents and serious injuries can occur if the vehicle is parked without sufficient illumination, as
other road users might have difficulty seeing the vehicle, or may not see it at all.
Always park the vehicle safely and with sufficient lighting. Observe any applicable local regulations.
If the vehicle lighting is required for several hours, switch on the right or left parking light if possible.
The illumination time of the parking light on one side is generally twice as long as for continuous
parking light on both sides of the vehicle.

Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching the auxiliary heater and ventilation on and off 
⇒ Programming the auxiliary heater and ventilation 
⇒ Remote control 
The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and
ventilate it in the summer. It is able to clear ice, condensation and a thin layer of snow from the
windscreen. The auxiliary heater is supplied with fuel from the vehicle fuel tank and can be operated
when the vehicle is stationary with the ignition switched off. The auxiliary ventilation system is
powered by the 12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions generated by the auxiliary heater are discharged via an exhaust pipe underneath the
vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.

WARNING
Among other things, the emissions from the auxiliary heater contain carbon monoxide, which is an
odourless and colourless poisonous gas. Carbon monoxide can cause people to lose consciousness. It
can also cause death.
Never switch on the auxiliary heater when the vehicle is in unventilated or closed rooms nor let the
auxiliary heater run in unventilated or closed rooms.
Never program the auxiliary heater so that it is switched on and runs in unventilated or closed
rooms.

WARNING
Parts of the auxiliary heater exhaust system become very hot. This can cause fires.
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable
material underneath the vehicle, e.g. dry grass.

NOTICE
Food, medicine and other items that are sensitive to heat or cold could be either damaged or
rendered useless by the air flowing out of the vents.
Never leave food, medicines or other temperature-sensitive objects in front of the vents.
Switching the auxiliary heater and ventilation on and off
First read and observe the introductoryinformation and safety warnings⇒Introduction 
The auxiliary heater can be operated only when the ignition is switched off. If the ignition is switched
on while the auxiliary heater is working, the auxiliary heater continues to run to provide additional
heat.
Switching on the auxiliary heater
Press the immediate heat button in the air conditioning block ⇒ Front controls .
OR: press the button on the remote control ⇒ Remote control .
OR: program the departure time ⇒ Programming the auxiliary heater and ventilation .
The auxiliary heater heats the vehicle interior to at least 22 ℃.
The auxiliary heater will not switch on if the 12-volt vehicle battery is low or the fuel tank is empty.
Switching off the auxiliary heater manually
Press the immediate heat button in the air conditioning block ⇒ Front controls .
OR: press the button on the remote control ⇒ Remote control .
OR: touch the function button on the Infotainment system ⇒ Programming the auxiliary heater
and ventilation .
Auxiliary heater switches off automatically
When the programmed departure time is reached, or after the programmed operating period has
elapsed ⇒ Programming the auxiliary heater and ventilation .
When the indicator lamp lights up (fuel gauge) ⇒ Fuel gauge .
If the charge level of the 12-volt vehicle battery is too low ⇒ 12-volt vehicle battery .
The auxiliary heater runs on for a short time after it has been switched off manually or automatically
so that the remaining fuel in the system can be burnt off.

When the vehicle is at a standstill, the auxiliary heater can be activated up to three times in
succession for the maximum operating duration.

Operating noises can be heard if the auxiliary heater is switched on.

The 12-volt vehicle battery will discharge if the auxiliary heating or ventilation is run several times
over an extended period. Drive the vehicle for an appropriate distance in between in order to
recharge the 12-volt vehicle battery.

The fuel gauge indication may not be accurate (just above the reserve quantity) when the vehicle is
parked on a slope; this may restrict the function of the auxiliary heater.

The auxiliary heater may switch on automatically when the engine is started at temperatures below
+5°C (+41°F) in order to provide additional hea ng power. The supplementary heating function will
switch off again automatically after a short time.
