Alarm systemThe conceptWhen the vehicle is locked, the vehicle alarm
system responds to:▷Opening a door, the hood or the trunk lid.▷Movements in the interior.▷Changes in the vehicle tilt, e. g., during at‐
tempts at stealing a wheel or when towing
the car.▷Disconnected battery voltage.
The alarm system briefly signals tampering:
▷By sounding an acoustic alarm.▷By switching on the hazard warning sys‐
tem.▷By flashing the daytime running lights.
Arming and disarming the alarm
system
When you unlock or lock the vehicle, either
with the remote control or via the Comfort Ac‐
cess, the alarm system is disarmed or armed at
the same time.
Door lock and armed alarm systemThe alarm system is triggered when the door is
opened, when the vehicle is unlocked via the
door lock.
Trunk lid and armed alarm system The trunk lid can be opened even when the
alarm system is armed.
After the trunk lid is closed, it is locked and
monitored again when the doors are locked.

Transporting children safelyVehicle features and optionsThis 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 tothe 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.
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 systems provided in
accordance with the age, weight and size of
the child; otherwise, there is an increased risk
of injury in an accident.
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
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 system in the front passenger seat,
make sure that the front, knee and side airbags
on the front passenger side are deactivated.
Automatic deactivation of front-seat passen‐
ger airbags, refer to page 97.Note
Deactivating the front-seat passenger
airbags
If a child restraint system is used in the front
passenger seat, deactivate the front-seat pas‐
senger airbags; otherwise, there is an in‐
creased risk of injury to the child when the air‐
bags are activated, even with a child restraint
system.◀
Installing child restraint
systems
Hints Manufacturer's information for child re‐straint systems
To select, mount and use child restraint sys‐
tems, observe the information provided by the
system manufacturer; otherwise, the protec‐
tive effect can be lost.◀
Ensuring the stability of the child seat
When installing child restraint systems,
make sure that the child seat is securely fas‐
tened to the backrest of the seat. Angle and
headrest of the backrest might need to be ad‐
justed or possibly be removed. Make sure that
all backrests are securely locked. Otherwise
the stability of the child seat can be affected,
and there is an increased risk of injury becauseSeite 59Transporting children safelyControls59

switched off accidentally.◀
The ignition automatically cuts off while the
vehicle is stationary and the engine is stopped:▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available

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 place the trans‐
mission in selector lever position P or N to pre‐
vent the vehicle from moving.◀
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.
