Alarm system
The concept
The vehicle alarm system responds to:▷Opening of a door, the hood or the trunk lid.▷Movements in the vehicle.▷Changes in the vehicle tilt, e.g., during at‐
tempts to steal a wheel or when towing the
car.▷Interruptions in battery voltage.
The alarm system briefly indicates tampering:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.▷By flashing the daytime running lights.
Arming and disarming the alarm
system
General information
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.

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 94.
Note Deactivated 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 94Seite 55Transporting children safelyControls55

Mounting points
Depending on the vehicle equipment, there are
two outer or three mounting points for child re‐
straint fixing systems with a tether strap.
Retaining strap guide Retaining strap
Make sure that the upper retaining strap is
not routed over the head restraints or sharp
edges and is free of twisting on its way to the
upper mounting point; otherwise, the belt can‐
not properly secure the child restraint fixing sys‐
tem in an accident.◀

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.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times 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 mod‐
erate engine speeds.
Diesel engine
If the engine is cold and temperatures are below
approx. 32 ℉/0 ℃, the start process may be de‐
layed somewhat due to automatic preheating.
