Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.
Suitable parking space
General information:
▷Gap behind an object that has a min. length
of 1.7 ft/0.5 m.▷Gap between two objects with a minimum
length of approx. 1.7 ft/0.5 m.
Parallel parking to the road:
▷Min. length of gap between two objects:
your vehicle's length plus approx.
2.6 ft/0.8 m.▷Minimum depth: approx. 5 ft/1.5 m.
Diagonal parking:
▷Width of gap between two objects: your
vehicle's width plus approx. 2.3 ft/0.7 m up
to maximum 16 ft/5 m.▷Minimum depth: your vehicle's length.
The depth of diagonal parking spaces must
be estimated by the driver. Dur to technical
limitations, the system can approximate
the depth of diagonal parking spaces only.
Regarding the parking procedure
▷Doors and trunk lid closed.▷Parking brake released.▷When parking in parking spaces on the
driver's side, the corresponding turn signal
must be set where applicable.
Overview
Button in the vehicle
Parking assistant
Ultrasound sensors
The four ultrasound sensors for measuring
parking spaces are located in the front and rear
on the side of the vehicle.
To ensure full functionality:
▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.▷Do not put stickers over sensors.Seite 126ControlsDriving comfort126

sired program or the desired in‐
termediate setting.▷ Windows.▷ Upper body region.▷ Windows, upper body region, and foot‐
well.▷ Footwell.
Defrosts windows and removes
condensation
Direct the air distribution toward windows, in‐
crease the air flow and temperature, and, if
needed, use the cooling function.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.
Air flow, manual Press the left or right side of the but‐
ton: decrease or increase air flow.
The air flow from the air conditioner may be re‐
duced automatically to save battery power.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and
into the footwell.
The cooling function, refer to page 131, is
switched on automatically with the AUTO pro‐
gram.
Temperature Turn the ring to set the desired
temperature.
The automatic climate control reaches this
temperature as quickly as possible, if needed
by increasing the cooling or heating output,
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.
Cooling function The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidi‐
fied and, depending on the temperature set‐
ting, warmed again.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 154, devel‐
ops that exits underneath the vehicle.
Recirculated-air mode You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently within the vehicle.Seite 131Climate controlControls131

condensation
Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
For this purpose, point the side vents onto the
side windows as needed.
Adjust air flow with the program active.
If the windows are fogged over, you can also
switch on the cooling function or press the AUTO button to utilize the condensation sen‐
sor.
Switching the system on/off Switch off Press the left button for the minimum
speed.
Switching on
Press any button except▷Rear window defroster.▷Seat heating.
Microfilter/activated-charcoal filter
In external and recirculated air mode the mi‐
crofilter/activated charcoal filter filters dust,
pollen, and gaseous pollutants out of the air.
This filter should be replaced during scheduled
maintenance, refer to page 191, of your vehi‐
cle.

Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset reel-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.

Wheels and tiresVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 1.45 psi/0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 173, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 173, and adjust as necessary.
Seite 172MobilityWheels and tires172
Online Edition for Part no. 01 40 2 961 270 - II/15

These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀
