HintsSufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀
Climate control functions in detail
Manual air distribution Press button repeatedly to select a
program:▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell.▷Windows, upper body region, and footwell.▷Windows: driver's side only.▷Windows and upper body region.
If the windows are fogged over, press the
AUTO button on the driver's side to utilize the
condensation sensor.
Temperature Turn the ring to set the desired
temperature.
The automatic climate control achieves this
temperature as quickly as possible, if needed
by using the maximum cooling or heating li‐
dacity, and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
AUTO program
Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 164, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.
Intensity of the AUTO program
With the AUTO program activated, the auto‐
matic intensity control can be changed.
Press the left or right side of the but‐
ton: decrease or increase the inten‐
sity.

▷When the engine is running or when elec‐
trical drive readiness is available.
Residual cooling
When the automatic climate control has re‐
duced the interior temperature, this tempera‐
ture can be maintained after the engine has
been switched off. This function can be acti‐
vated up to 15 minutes after the engine is
switched off and for a maximum period of 6 mi‐
nutes.

▷The high-voltage battery is sufficiently
charged.▷External temperature at least ap‐
prox. 59 ℉/15 ℃.

trol Display disappears.
Parked-car ventilation The conceptThe parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off di‐
rectly or by using two preset reel-on times. It
remains switched on for 30 minutes.
Open the vents to allow air to flow out.

The system will only be switched on within the
next 24 hours. After that, it needs to be reacti‐
vated.
Auxiliary air conditioning
The concept Auxiliary air conditioning cools the heated ve‐
hicle interior immediately prior to driving off.
The automatic climate control lowers the inte‐
rior temperature with high cooling output.
The auxiliary air conditioning can be switched
on or off using the remote control.
The system is activated for approx. two mi‐
nutes.
Functional requirement

Low energy recovery:
During coasting to a halt without stepping on
the brake.
Average energy recovery:
During a slight deceleration by gently pressing
the brake pedal.
Maximum energy recovery:
During firmer pressing on the brake pedal.
Foresighted driving and decelerating helps
with optimizing energy recovery.
Brake according to traffic and circum‐
stances
Brake in accordance with the traffic conditions,
or there is the risk of accident.◀
Optimum energy recovery
As soon as the display shows the maximum
energy recovery, only press the brake pedal
harder if required by the situation.
Exemplary traffic situations for fuel
efficiency
In many driving situations, the hybrid system
allows for a particularly efficient energy man‐
agement.▷Stop-and-go traffic:
The combustion engine is switched on or
over automatically by the hybrid system.▷Driving with constant speed:
With the ASSIST acceleration support, the
electric motor relieves the combustion en‐
gine periodically by being switched on au‐
tomatically.
Discharge of the high-voltage battery
In normal operation, a sufficient charging of the
high-voltage battery is ensured by energy re‐
covery.
Longer idle periods can reduce the charge
state of the high-voltage battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. If necessary, charge the high-voltage
battery by driving the vehicle. Check the
charge level regularly, and if needed recharge
the high-voltage battery by driving the vehicle.
Don't allow battery charge status to drop too
low - it will damage the battery.◀
Charging by driving
In order to charge the high-voltage battery
most effectively when driving, activated the
transmission's Sport program DS, refer to
page 85.
