Securing cargo
Stow and secure the cargo as described
above; otherwise it may present a danger to
the occupants, e.g., during braking and evasive
maneuvers.◀
Roof-mounted luggage rack Note
Roof racks are available as special accessories.
Securing
Follow the installation instructions of the roof
rack.
Roof drip rail with flaps
The anchorage points are located in the roof
drip rail above the doors.
Fold the cover outward.
Loading Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
Because roof racks raise the vehicle's center
of gravity when loaded, they have a major ef‐
fect on vehicle handling and steering re‐
sponse.
Therefore, note the following when loading
and driving:
▷Do not exceed the approved roof/axle
loads and the approved gross vehicle
weight.▷Distribute the roof load uniformly.▷The roof load should not extend past the
loading area.▷Always place the heaviest pieces on the
bottom.▷Secure the roof luggage firmly, e.g., tie
with ratchet straps.▷Do not let objects project into the opening
path of the trunk lid.▷Drive cautiously and avoid sudden acceler‐
ation and braking maneuvers. Take corners
gently.Seite 177LoadingDriving tips177

Saving fuelVehicle 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 to
the selected options or country versions. This
also applies to safety-related functions and
systems.
General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 178Driving tipsSaving fuel178

Vehicle batteryMaintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
service life of the battery.
Further information about the battery can be
obtained from your service center.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery
registered on the vehicle by your service cen‐
ter to ensure that all comfort features are fully
available and that any Check Control mes‐
sages of these comfort features are no longer
displayed.
Charging the battery
Note Do not connect charging devices to the12 volt socket in the vehicle
Do not connect battery chargers to the fac‐
tory-installed 12 volt sockets in the vehicle as
this may damage the vehicle battery due to an
increased power consumption.◀
General information Make sure that the battery is always suffi‐
ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 219, in the
engine compartment with the engine off.
Power failure After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e.g.:
▷Seat and mirror memory: store the posi‐
tions again.▷Time: update.▷Date: update.▷Glass sunroof and sliding visor: initialize
the system, refer to page 50.
Disposing of old batteries
Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.
Fuses Hints Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substi‐
tute of another color or amperage rating; this
could lead to a circuit overload, ultimately re‐
sulting in a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box
in the cargo area.

Hybrid system: contact with water
The hybrid system is typically safe even in the
following example situations:▷Water in the footwell, for instance after a
rainstorm when sunroof was kept open.▷Vehicle is in water but only up to the al‐
lowed height.▷Liquid eslides in the cargo area.
In these cases there is no risk of injury from
electrocution. Other damage to the vehicle is
possible.
Hybrid system: automatic
deactivation
If an accident occurs, the hybrid system is
switched off automatically to prevent risk of
danger to occupants and other traffic.
Read the information on What to do after an
accident, refer to page 222.
What to do after an accident Hints After an accident
After an accident, do not touch any high-
voltage components such as orange colored
high-voltage cables or parts that are in contact
with exposed high-voltage cables. Otherwise,
there is the risk of fatal injury from electrocu‐
tion due to the system's high voltage.◀
Esliding fluids
Do not touch any fluids esliding from the
high-voltage battery, or the skin can sustain
chemical burns.◀
