Distronic
Safety notes
When activated, the Distronic adaptive cruise
control increases the driving convenience
afforded by the cruise control while traveling
on expressways and other major roadways.
R If the Distronic distance sensor detects a
slower moving vehicle directly ahead, your
vehicle speed will be reduced so that you
follow that vehicle at your preset following
distance.
R If there is no vehicle directly ahead of you,
the Distronic will function in the same way
as standard cruise control ( Y page 141).
GWarning!
The Distronic requires familiarity with its
operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.
GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not recognize
potential danger.
GWarning!
When the Distronic is braking, the brake pedal
is retracted (i.e. depressed automatically).
The pedals’ range of motion must not be
impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others.
GWarning!
The Distronic is a convenience system. Its
speed adjustment reduction capability is
intended to make cruise control more
effective and usable when traffic speeds vary.
It is not however, intended to, nor does it,
replace the need for extreme care.
The responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The Distronic cannot take street and traffic
conditions into account. Complex driving
situations are not always fully recognized by
the Distronic. This could result in wrong or
missing distance warnings.
GWarning!
The Distronic adaptive cruise control is not a
substitute for active driving involvement. It
does not react to pedestrians or on stationary
objects, nor does it recognize or predict the
lane curvature or the movement of preceding
vehicles.
The Distronic can only apply 20% of the
maximum braking power of the vehicle.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other driving

Loading and storing
Loading instructions
GWarning!
Always fasten items being carried as securely
as possible. Use cargo tie-down rings and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.

The cargo compartment is the preferred place
to carry objects. Always use cargo tie-down
rings, and if so equipped, always use the cargo
net when transporting cargo.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution
The Gross Vehicle Weight (GVW) is the weight
of the vehicle including:Rfuel
Rtools
Rspare wheel
Rinstalled accessories
Rpassengers
Rluggage/cargo
It must never exceed the load limit and the
Gross Vehicle Weight Rating (GVWR) for your
vehicle. The load limit and the GVWR are
specified on the placard located on the
driver’s door B-pillar (Y page 227).
In addition, the load must be distributed so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the certification
label located on the driver’s door B-pillar
(Y page 227).
For more information, see “Tire and Loading
Information” (Y page 227).
The handling characteristics of a fully loaded
vehicle depend greatly on the load
distribution. It is therefore recommended to
load the vehicle according to the illustration
shown. The heaviest items are to be placed
towards the front of the vehicle.
i The cargo compartment is the preferred
place to carry objects. The expanded cargo
volume (Y page 189) should only be used
for items which do not fit in the cargo
compartment alone.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
RAlways place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
RThe heaviest portion of the cargo should
always be kept as low as possible against
front or rear seat backrests.
For additional safety when transporting cargo
while the rear seats are unoccupied, fasten
the outer seat belts crosswise into the
opposite side buckles.

GWarning!
Only use carriers when the basic carrier bars
have been completely mounted. The left and
right roof rails are only stabilized by means of
the basic carrier bars mounted.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly
attached carrier or its load could become
detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof is
loaded, the handling characteristics are
different from those when operating the
vehicle without the roof loaded.

Parcel nets
GWarning!
Vehicles with Occupant Classification System
(OCS)
Do not place objects with a combined weight
of more than 4.4 lbs (2 kg) into the parcel net
on the back of the front passenger seat.
Otherwise, the OCS may not be able to
properly approximate the occupant weight
category.
GWarning!
Parcel nets are intended for storing light-
weight items only, such as road maps, mail,
etc.
Heavy objects, objects with sharp edges, or
fragile objects may not be transported in the
parcel nets. In an accident, during hard
braking, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
Parcel nets cannot protect transported goods
in the event of an accident.
Parcel nets are located in the front passenger
footwell and on each of the front seat
backrests.
Cargo tie-down rings
Your vehicle is equipped with six cargo tie-
down rings.
Always follow loading instructions
(Y page 186).
Carefully secure cargo by applying even load
on all the cargo tie-down rings with a rope of
sufficient strength to hold down the cargo.

Hooks
Four hooks are located on the rear
compartment trim panels, two on each side.
Use the hooks to secure light-weight items
only. The maximum permissible weight per
hook is 9 lbs (4 kg).
Expanding cargo volume
You can separately fold the left and right rear
seat backrests to expand the cargo volume.
GWarning!
When expanding the cargo volume, always
fully fold the corresponding seats and, if so
equipped, always use the cargo net when
transporting cargo.
Unless you are transporting cargo, the seat
backrests must remain properly locked in the
upright position.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
Always use the cargo tie-down rings.
GWarning!
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Folding rear seat backrest forward
! Always release the seat cushion and fold
it up before folding the seat backrest

Never use a damaged cargo net.
Always use cargo net when transporting
cargo. This helps to avoid personal injury from
smaller objects being thrown around in the
occupant compartment during a collision or
sudden maneuver.
The cargo net cannot prevent the movement
of large, heavier objects into the passenger
compartment in an accident. Such items must
be properly secured using the cargo tie-down
rings in the cargo compartment floor.
Passenger use of seats behind installed cargo
net is restricted because of the footwell being
taken up by the net.
Use of the cargo net is a particularly
important safety factor when the vehicle is
loaded higher than the top of the seat
backrests with smaller objects. For your
safety, always use the cargo net when
transporting cargo.
The cargo net can be installed behind the
B-pillar or the C-pillar.
