▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, for ex‐
ample, the ignition is automatically switched off
for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
If the engine is switched off and the ignition is
switched on, the system automatically switches
to the radio-ready state if the lights are turned
off or, if correspondingly equipped, the day‐
time running lights are activated.
Starting the engine
Information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel
chock. ◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession. ◀
Steptronic transmission
Starting the engine
1.Depress the brake pedal.2.Engage selector lever position P or N.3.Press the Start/Stop button.
The ignition is activated automatically for a cer‐
tain time and is stopped as soon as the engine
starts.

Starting the engine
1.Depress the brake pedal.2.Press on the clutch pedal and shift to neu‐
tral.3.Press the Start/Stop button.
The ignition is activated automatically for a cer‐

Information WARNING
Unattended children or animals can move
the vehicle and endanger themselves and traf‐
fic, for example with the following actions:

Objects in the area around the pedalsWARNING
Objects in the driver's floor area can limit
the pedal distance or block a depressed pedal.
There is risk of an accident. Stow objects in the
vehicle such that they are secured and cannot
enter into the driver's floor area. Use floor mats
that are suitable for the vehicle and can be
safely attached to the floor. Do not use loose
floor mats and do not layer several floor mats.
Make sure that there is sufficient clearance for
the pedals. Ensure that the floor mats are se‐
curely fastened again after they were removed,
for example for cleaning. ◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other
traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills WARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system. ◀
WARNING
In idle or with the engine switched off,
safety-relevant functions are restricted or not
available anymore, for example braking effect
of the engine or braking force and steering
support. There is risk of an accident. Do not
drive in idle or with the engine switched off. ◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
needed.
Brake disc corrosion Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during brak‐
ing is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked vehicle When using the automatic climate control, con‐
densation water develops collecting under‐
neath the vehicle.
Ground clearance CAUTION
If ground clearance is insufficient, there
might be contact with the front or rear spoiler
for example when driving over curbs or enter‐
ing into underground car parking garages.
There is risk of property damage. Ensure that
there is sufficient ground clearance available. ◀

4.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.5.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.6.With operating readiness switched on or
the engine running, switch on the compres‐
sor.
Let the compressor run for max. 10 minutes to
fill the tire with sealant and achieve a tire infla‐
tion pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not switch off the compressor
at this point.
CAUTION
The compressor can overheat during ex‐
tended operation. There is risk of property
damage. Do not run the compressor for more
than 10 min. ◀
If a tire inflation pressure of 2 bar is not
reached:1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive forward and back to distribute the
sealant in the tire.4.Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your dealer’s service cen‐
ter or another qualified service center or re‐
pair shop.
Stowing the Mobility System
1.Remove the connection hose of the sealant
container from the wheel.2.After pressing the red unlock button on the
compressor, remove the sealing container.3.Wrap the empty sealant container in suita‐
ble material to avoid dirtying the trunk.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
