If equipped with through-loading system: the
rear seat backrest is divided in the ratio 40–20–
40. The sides and the middle section can be
folded down separately.
Hints Danger of jamming
Before folding down the rear seat back‐
rests, ensure that the area of movement of the backrests is clear. In particular, ensure that no
one is located in or reaches into the area of
movement of the rear seat backrests when the
middle section is folded down. Otherwise, in‐
jury or damage may result.◀
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 because
of unexpected movement of the seat back‐ rest.◀
Ensure that the lock is securely engaged
When you fold back the backrest make
sure that it locks in place. When this happens
the red warning field on the seat disappears.
Otherwise transported cargo could shoot into
the car's interior during braking or evasive ma‐
neuvers and endanger occupants.◀
Using the middle safety belt
If the middle safety belt in the rear is
used, the larger side of the backrest must be locked. Otherwise, the safety belt will not have
a restraining effect.◀
Folding down the sidesThe right side can be folded down separately.
The left side can be folded down in combina‐
tion with the middle section.
Reach into the recess and pull forward.
Folding down the middle section
Reach into the recess and pull forward.

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷Cover sharp edges and corners on the
cargo.▷Heavy cargo: stow as far forward as possi‐
ble, directly behind and at the bottom of
the rear passenger seat backrests.▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.▷If necessary, fold down the rear backrests
to stow cargo.▷Do not stack cargo above the top edge of
the backrests.▷Use the trunk partition net, refer to
page 166, to protect passengers. Make
sure that objects cannot penetrate the
trunk partition net.Securing cargo

Engine does not start
Do not continue driving to the limit of the
remaining travel distance. Otherwise, you will
not be able to restart the engine after switch‐
ing it off. In certain cases, this could cause
safety to be impaired.◀
Filling with an incorrect fluid A Check Control message is displayed when
an incorrect fluid is added.
After adding the incorrect fluid, contact your
service center.
System defect A Check Control message is displayed when
there is a system defect.
Have the diesel exhaust fluid
replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, e.g., if the vehicle is driven in a partic‐
ularly sporty style or if it is driven at high
altitudes.
The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible
that the reducing agent may also need to be
replenished between regular maintenance ap‐
pointments if it is exposed to temperatures un‐
der + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before driving off.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃, the fill‐
ing level cannot be measured in some cases.
After adding reducing agent, the Reserve Dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid
When working with reducing agent in
closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may eslide.◀
Keeping Diesel exhaust fluid out of reach
of children
Keep reducing agent out of reach of children.◀
Avoid contact with surfaces

Engine oilVehicle 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.
General information The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
case of, for example:▷Sporty driving.▷Break-in the engine.▷Idling of the engine.▷Usage of non-approved engine oil grades.
Therefore, regularly check the engine oil level
after refueling.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles:
▷Status display▷Detailed measurement
Electronic oil measurement
Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Dis‐
play.
If the engine oil level reaches the minimum
level, a check control message is displayed.
Requirements
A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly
perform a detailed measurement.
Displaying the engine oil level1."Vehicle info"2."Vehicle status"3. "Engine oil level"
Engine oil level display messages
Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low, within the next
125 miles/200 km Add engine oil, refer to
page 211.
Engine oil level too low
Add engine oil immediately; otherwise,
an insufficient amount of engine oil could re‐
sult in engine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus engine oil can lead to en‐
gine damage.◀
Detailed measurement

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 the service center
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
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.
Hints
Do not connect charging devices to the
12 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.◀
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 228, 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: 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 trunk.
