Transporting children safelyVehicle equipment
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 sys‐
tems.
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.◀

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. Incorrectly or
improperly installed child restraint systems can
increase the risk of injury to children. Always fol‐
low 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 as
high as possible to obtain the best possible po‐
sition for the belt.Seite 43Transporting children safelyControls43

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 ve‐
hicle 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 capacity.
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 avail‐
able cargo and luggage load capacity is
650 lbs: 1,400 lbs minus 750 lbs = 650 lbs.5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. 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 transporting
a trailer to determine how this may reduce
the available cargo and luggage load ca‐
pacity 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
Trunk
▷Heavy cargo: stow as far forward and as low
as possible, ideally directly behind the trunk
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 34.

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 wind‐
shield and the sun visor.◀
Light and small objects can be stored on the lat‐
eral storage shelf.
Securing cargo
Trunk
Use retaining straps, a luggage net or draw
straps to secure small and lightweight items.
Lateral 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 168, 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.

FuelVehicle equipment
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 sys‐
tems.
Fuel quality
Do not use fuels that are labeled at the fuel pump
as containing metals.
Only refuel with lead-free gasoline without
metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀
Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
Gasoline with lower AKI
However, you may also use gasoline with less
AKI.
The minimum AKI rating is: 89
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.This has no effect on the engine life.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada.
Fuels containing up to and including 10 % etha‐
nol or other oxygenates with up to 2.8 % oxygen
by weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will not
void the applicable warranties with respect to
defects in materials or workmanship.
Minimum fuel grade
The use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.◀Seite 154MobilityFuel154
