Transporting children safelyVehicle 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 tothe 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.
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 should always be in the rear Accident research shows that the safest place
for children is in the back seat.
Transporting children in the rear
Only transport children younger than
13 years of age or shorter than 5 ft/150 cm in
the rear in child restraint systems provided in
accordance with 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
system can no longer be used due to their age,
weight and size.◀
Children on the front passenger seat
Should it ever be necessary to use a child re‐
straint system in the front passenger seat,
make sure that the front, knee and side airbags
on the front passenger side are deactivated.
Automatic deactivation of front-seat passen‐
ger airbags, refer to page 101.Note
Deactivating the front-seat passenger
airbags
If a child restraint system is used in the front
passenger seat, deactivate the front-seat pas‐
senger airbags; otherwise, there is an in‐
creased risk of injury to the child when the air‐
bags are activated, even with a child restraint
system.◀
Installing child restraint
systems
Hints Manufacturer's information for child re‐straint systems
To select, mount and use child restraint sys‐
tems, observe the information provided by the
system manufacturer; otherwise, the protec‐
tive effect can be lost.◀
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 becauseSeite 60ControlsTransporting children safely60

LATCH child restraint systemLATCH: Lower Anchors and Tether for Chil‐
dren.
Note Follow manufacturer's information for
LATCH child restraint systems
To mount and use the LATCH child restraint
systems, observe the operating and safety in‐
formation from the system manufacturer; oth‐
erwise, the level of protection may be re‐
duced.◀
Mounts for the lower LATCH anchors
The lower anchors may be used to attach the
CRS to the vehicle seat up to a combined child
and CRS weight of 65 lb/30 kg when the child
is restrained by the internal harnesses.
Note Properly engage the lower LATCH an‐
chors
Make sure that the lower LATCH anchors have
properly engaged and that the child restraint
system is resting snugly against the backrest;
otherwise, the degree of protection may be re‐
duced.◀
Position The corresponding symbol shows the
mounts for the lower LATCH anchors.
Seats equipped with lower anchors are
marked with a pair, 2, of LATCH sym‐
bols. It is not recommended to use the
inner lower anchors of standard outer
LATCH positions to fasten a child restraint
system on the middle seat. Use the vehicle
seat belt instead for the middle seat.Before installing LATCH child
restraint systems
Pull the belt away from the area of the child re‐
straint system.
Assembly of LATCH child restraint
systems1.Mount the child restraint system; refer to
the user's manual of the system.2.Ensure that both LATCH anchors are prop‐
erly connected.
Upper LATCH retaining strap
For Canadian customers Only.
The following statement is required by Trans‐ port Canada:
This vehicle is not equipped with user-ready
tether anchorages. As such neither a child re‐
straint system, nor a booster cushion, requirer‐
ing the use of a tether strap can be properly
secured in the vehicle.

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.◀
Loading with hardtop open
Before opening the hardtop, fold down
the cargo area partition and make sure the
loading is correct. Otherwise, parts of the hard‐
top can be damaged.◀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
1,000 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 162Driving tipsLoading162
Online Edition for Part no. 01 40 2 960 812 - II/15
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.▷Use loading aid, refer to page 148, for eas‐
ier loading.▷Using the trunk, refer to page 48.▷Do not stack cargo above the top edge of
the backrests.Securing cargo
Lashing eyes in the trunk
To secure the cargo there are four lashing
eyes in the cargo area.
Floor net
The floor net can also be used to secure cargo
and store small parts.
Hook the floor net into the fittings in the trunk
floor.
Securing cargo Securing cargo
Stow and secure the cargo as described;
otherwise it may present a danger to the occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀
▷Smaller and lighter items: secure with re‐
taining straps or draw straps.▷Larger and heavy objects: secure with
cargo straps.
Attach the cargo straps, retaining straps or
draw straps to the lashing eyes in the trunk.

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. The respectively applicable country
provisions must be observed when using the
respective features 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 cargo
Additional weight increases fuel consumption.
Remove attached parts
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.
Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. WhenSeite 164Driving tipsSaving fuel164
