windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.

Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Parking heater
The parking heater allows to heat the
vehicle's interior and to ventilate the
vehicle's interior with ambient air.
The operating status of the parking
heater is shown by an indicator with a LED.
● LED illuminates: A timer has been set.
● LED flashes: The system is operating.
The LED is extinguished at the end of
the heating operation or when the
parking heater is stopped using the
remote control.
The parking heater can be
programmed using the Graphic Info
Display / Colour Info Display.
Additionally, the parking heater can
be switched on and off using a remote control.
Notice
The programmed heating /
ventilation is only activated if the
ignition is off and the vehicle is
locked.
If the charging level of the high
voltage battery is below 50%, the
programmed heating / ventilation is
not activated.
If a recurrent heating / ventilation is
programmed and two heating /
ventilation procedures are carried
out without operating the vehicle, the
programmation is deactivated.
Driving and operating139The engine will be switched off whilethe ignition stays on.Vehicles with automatic transmission
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while
the ignition stays on.
The stop-start system will be disabled
on inclines of 12% or more.
Indication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● 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 engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is not too low or too high.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.
● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.Notice
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop.
Climate control 3 123.
Immediately after higher speed
driving an Autostop may be inhibited.
New vehicle running-in 3 134.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Driving and operating145event, park the vehicle in a space
with a higher ambient temperature
until AdBlue is liquified.
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 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
5 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.
Notice
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before
AdBlue dries out.
232Vehicle careinformation label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre deflation detectionsystem
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 98.After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 266.
2. Apply parking brake. 3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
