Transporting children safelyVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
The right place for children
Note Children in the vehicle
Do not leave children unattended in the
vehicle; otherwise, they could endanger them‐
selves and other persons, e.g., by opening the
doors.◀
Children should always be in the rear
Accident research shows that the safest place
for children is in the back seat.
Transporting children in the rear
Only transport children younger than
13 years of age or shorter than 5 ft/150 cm in the
rear in child restraint fixing systems provided in
accordance with the age, weight and size of the
child; otherwise, there is an increased risk of in‐
jury in an accident.
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
fixing system can no longer be used, due to their
age, weight and size.◀
Children on the front passenger seat
Should it ever be necessary to use a child re‐
straint fixing system in the front passenger seat,
make sure that the front, knee and side airbags
on the front passenger side are deactivated. Au‐tomatic deactivation of front passenger airbags,
refer to page 93.
Deactivating the front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there is
an increased risk of injury to the child when the
airbags are triggered, even with a child restraint
fixing system.◀
Installing child restraint fixing
systems
Before mounting
Before mounting child restraint fixing systems,
ensure that the rear seat backrests are locked.
Notes Manufacturer's information for child re‐
straint fixing systems
To select, mount and use child restraint fixing
systems, observe the information provided by
the system manufacturer; otherwise, the pro‐
tective effect can be impaired.◀
On the front passenger seat
Deactivating airbags
After installing a child restraint fixing system in
the front passenger seat, make sure that the
front, knee and side airbags on the front pas‐
senger side are deactivated.
Deactivate the front passenger airbags auto‐
matically, refer to page 93.
Deactivating the front passenger airbags

Start/Stop button
The concept Pressing the Start/Stop button
switches the ignition on or off and
starts the engine.
Automatic transmission: the en‐
gine starts if the brake is de‐
pressed when the Start/Stop button is pressed.
Manual transmission: the engine starts if the
clutch is depressed when the Start/Stop button
is pressed.
Ignition on
Automatic transmission: press the Start/Stop
button, and do not press on the brake pedal at
the same time.
Manual-shift transmission: press the Start/Stop
button, and do not press on the clutch pedal at
the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lamps in the
instrument cluster light up for varying lengths of
time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
The ignition switches off automatically:▷When the vehicle is locked, if the low beams
are switched on.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.▷If the engine is switched off and the ignition
is switched on, the system automatically
switches to the radio ready state when the
door is opened if the lights are switched off
or the daytime running lights are switched
on.
If the engine is switched off and the ignition
is switched on, the system automatically
switches to the radio ready state when the
door is opened if the lights are switched off.
Ignition off
Automatic transmission: press the Start/Stop
button again, and do not press on the brake
pedal at the same time.
Manual-shift transmission: press the Start/Stop
button again, and do not press on the clutch
pedal at the same time.
All indicator lamps in the instrument cluster go
out.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Transmission position P with the ignition
off
When the ignition is switched off, position P is
engaged automatically. When in an automatic
car wash, for example, ensure that the ignition is
not switched off accidentally.◀

▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available when
the low beams are switched off.▷When opening and closing the driver door, if
the driver's seat belt is unbuckled and the
low beams are switched off.▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low beams
are switched off.
When the ignition is switched off, by opening or
closing the driver's door or unbuckling the driv‐
er's seat belt, the radio ready state remains ac‐
tive.
Radio ready state
Activate radio ready state:
▷When the ignition is switched off: press ON/
OFF button on the radio.▷When the engine is running: press START/
STOP button.
Some electronic systems/power consumers re‐
main ready for operation.
Radio ready state switches off automatically:

completely, so that the engine can still be
started.
Starting the engine
General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of 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 dan‐
ger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving at mod‐
erate engine speeds.

Note
Even if driving away was not intended, the de‐
activated engine starts up automatically in the
following situations:
▷Excessive warming of the passenger com‐
partment when the cooling function is
switched on.▷The steering wheel is turned.▷Automatic transmission: the transmission
position is changed from D to N, R, or M/S.▷Automatic transmission: the transmission
position is changed from P to N, D, R, or M/
S.▷The vehicle begins rolling.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the passenger com‐
partment when the heating is switched on.▷Low brake vacuum pressure; this can occur,
for example, if the brake pedal is depressed
a number of times in succession.
Preventing an automatic engine stop
with automatic transmission
The concept
To make it possible to drive away very quickly,
such as at an intersection, the automatic engine
stop can be actively prevented.
