This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
Sitting safely
The ideal seating position can make a vital
contribution to relaxed, fatigue-free driving.
The seating position plays an important role in
an accident in combination with:▷Safety belts, refer to page 48.▷Head restraints.▷Airbags, refer to page 90.
Seats
Note before adjusting Do not adjust the seat while driving
Never attempt to adjust the driver's seat
while driving.
The seat could respond with unexpected
movement and the ensuing loss of vehicle
control could lead to an accident.◀
Do not incline the backrest too far to the
rear
Do not incline the backrest on the front pas‐
senger side too far to the rear during driving.
Otherwise, there is the danger of sliding under
the safety belt in an accident. This would elimi‐
nate the protection normally provided by the
belt.◀
Also note the information on safety belt dam‐
age, refer to page 49.
Adjusting manually
Forward/backward Pull lever 1 and slide the seat to the desired
position.
After releasing the lever, move the seat for‐
ward or back slightly to make sure it engages
properly.
Height
Pull lever 2 and apply your weight to the seat
or lift it off, as necessary.
Backrest tilt
Pull lever 3 and move the backrest to the de‐
sired tilt.

Transporting children safelyVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to 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 on the front passenger seat
Should it be necessary to use a child restraint
fixing system on the front passenger seat,
make sure that the front and side airbags on
the front passenger side are deactivated. Auto‐
matic deactivation of front passenger airbags,
refer to page 91.
Deactivating the 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 re‐
straint fixing system.◀
Transport children in suitable child re‐
straint fixing systems
Only transport children younger than 13 years
of age or shorter than 5 ft/150 cm in child re‐
straint fixing systems suitable for 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
fixing system can no longer be used, due to
their age, weight and size.◀
Installing child restraint
fixing systems
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.◀
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-
belt section of a lap-and-shoulder belt. Incor‐
rectly or improperly installed child restraint
systems can increase the risk of injury to chil‐
dren. Always follow the installation instructions
for the system with the greatest care.
On the front passenger seat Check the deactivation of the passenger
airbag
After installing a child restraint fixing system
on the passenger seat, make sure that the
front and side airbags on the passenger side
have been deactivated; otherwise, there is an
increased risk of injury when the airbags are
deployed.◀
Seat position
Before installing a child restraint fixing system,
move the passenger seat as far back and asSeite 53Transporting children safelyControls53

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 the
vehicle 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
1,400 lbs and there will be five 150 lbs pas‐
sengers in your vehicle, the amount of
available cargo and luggage load capacity
is 650 lbs: 1,400 lbs minus 750 lbs =
650 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 4.6.If your vehicle will be towing a trailer, load
from your trailer will be transfered to your
vehicle. Consult the manual for transport‐
ing a trailer to determine how this may re‐
duce the available cargo and luggage load
capacity of your vehicle.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
Cargo area
▷Heavy cargo: stow as far forward and as
low as possible, ideally directly behind the
cargo area separating wall.▷Cover sharp edges and corners.
Loading with the hardtop open
Before opening the hardtop, fold down
the cargo area partition and make sure the
cargo area is loaded correctly; otherwise, parts
of the hardtop could be damaged.◀
Fold down the cargo area partition, refer to
page 43.

Rear storage shelfLoading the rear storage shelf
When loading the rear storage shelf, do
not move both seats all the way forward while moving them to their uppermost position and
leaning the backrests forward. Otherwise, the seats could hit and damage the seal on the
windshield and the sun visor.◀
Light and small objects can be stored on the
rear storage shelf.
Securing cargo
Cargo area
Use retaining straps, a luggage net or draw
straps to secure small and lightweight items.
Rear storage shelf You can obtain cargo straps from your service
center. Four lashing eyes are provided behind
the seats for attaching the cargo straps.
Adhere to the information included with the
cargo straps.

Saving fuel
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.
The implementation of certain measures, driv‐
ing style and regular maintenance, refer to
page 241, can have an influence on fuel con‐
sumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following use
Remove auxiliary mirrors or rear-mounted lug‐
gage racks after use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
