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 daytime 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
exhaust pipe free and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can begin to move
and possibly 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 downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock.◀ATTENTION
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
a risk of damage to property. Avoid repeated
starting in quick succession.◀
Steptronic transmission
Starting the engine1.Depress the brake pedal.2.Press the Start/Stop button.
The ignition is activated automatically for a
certain time and is stopped as soon as the en‐
gine starts.
Engine stop
Information WARNING
Unattended children or animals can
cause the vehicle to move and endanger them‐
selves and traffic, e.g., due to the following ac‐
tions:
▷Pressing the Start/Stop button.▷Releasing the parking brake.▷Opening and closing the doors or win‐
dows.▷Engaging selector lever position N.▷Using vehicle equipment.
There is risk of accidents or injuries. Do not
leave children or animals unattended in the ve‐
hicle. Take the remote control with you when
exiting and lock the vehicle.◀

Braking safely
Your vehicle is equipped with ABS as a stand‐ ard feature.
Perform an emergency stop in situations that
require such.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can emit functional noises. How‐
ever, this has no effect on the performance and
operational reliability of the brake.
Objects in the movement area around
pedals and floor area
WARNING
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 clear‐
ance for the pedals. Ensure that the floor mats
are securely fastened again after they were re‐
moved, e.g., 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 state or with the engine switched
off, safety-relevant functions are restricted or
not available anymore, e.g., braking effect of
the engine or braking force and steering sup‐
port. There is risk of an accident. Do not drive
in idle state 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 the fol‐
lowing circumstances:▷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
braking 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.

4.Insert the sealant container on the com‐
pressor housing in an upright position.5.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.6.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.7.With the ignition turned on or the engine
running, switch on the compressor.
ATTENTION
The compressor can overheat during ex‐
tended operation. There is a risk of damage to
property. Do not run the compressor for more
than 10 min.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation 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 compres‐
sor at this point.
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 33 ft/10 m forward and back to dis‐
tribute 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
repair shop.
Stowing the Mobility System
1.Unscrew the filling hose of the sealant con‐
tainer from the wheel.2.Unscrew the connection hose of the com‐
pressor from the sealant container.3.Connect the filling hose of the sealant con‐
tainer previously connected to the tireSeite 214MobilityWheels and tires214
