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 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.

Engine stop
Hints Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., can‐
not start the engine.◀
Apply parking brake and further secure
the vehicle if needed.
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, e.g., by turning the steering wheel in the
direction of the curb.◀

LoadingVehicle features and options
This 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 to
the 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.
Hints Overloading the vehicle
To avoid exceeding the approved ca‐
pacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀
Heavy and hard objects
Do not stow any heavy and hard objects
in the car's interior without securing them; oth‐
erwise, they may present a danger to occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.Seite 173LoadingDriving tips173
