The radio-ready state switches off automati‐
cally:▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, e.g.,
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
Hints Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and engage trans‐
mission position P; otherwise, the vehicle may
begin to move.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.

Do not use Launch Control during the break-in,
refer to page  158, period.
Requirements Launch Control is available when the engine is
warmed up, that is, after uninterrupted driving
of at least 6 miles/10 km.
To start with Launch Control do not steer the
steering wheel.
Activate Launch Control1.Deactivate Dynamic Stability Control, refer
to page  117.2.Select Sequential mode with gear 1 and
driving program 3.3.With the engine running, apply the brake
with the left foot.4.Fully depress the accelerator pedal.
The starting engine speed adjusts.
A flag symbol appears in the instrument
cluster.5.If necessary, change the starting engine
speed by 500 rpm via cruise control.6.Release the brake, the vehicle accelerates.
Continue to depress the accelerator pedal.
Upshifting occurs automatically as long as
the accelerator pedal is fully depressed.
Launch Control is available again only after a
certain distance has been driven.
System limits
This transmission has an overheating protec‐
tion mechanism, which protects the clutch
from extreme stress.
▷Indicator lamp lights up yellow:
transmission too hot.
Avoid high engine stress and fre‐
quent starts.▷Indicator lamp lights up red: transmission
is overheating.
Further driving at a moderate pace is pos‐
sible. At the next opportunity, stop the car,shut off the engine and allow the transmis‐
sion to cool down.
Avoid fast starts, and on inclines did not accel‐
erate lightly while letting the clutch slip; other‐
wise, the transmission may overheat.
During traffic jams or at very low speeds, use
the Low Speed Assistant, refer to page  72.

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
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 Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
Manual transmission:
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
M double-clutch transmission:
You can increase the engine's braking effect
by shifting down in sequential mode, refer to
page  72.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored 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
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.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result.◀

pressor housing in an upright position.5.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the defective
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, reel on the compressor.
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
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 reel off the compressor 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 service center.
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 tire
valve with the available connector on the
sealant container.Seite 179Wheels and tiresMobility179
