Seat heating
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to high temperatures may be
affected or they may even suffer burn-like
injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
!When you leave your seat, do not place any-
thing on the seat and switch off the seat heat-
ing. Do not switch the seat heating on when
the seat is not occupied, e.g. when driving
without a front passenger. The seat heating
may otherwise overheat, causing damage to
the seat.
The three red indicator lamps in the Íbutton
show the activated heating level 1to 3.
The seat heating automatically switches down
from level 3to level 2after approximately seven
minutes.
The system automatically switches down from
level 2to level 1after approximately ten
minutes.
At level 1the seat heating switches off auto-
matically after approximately 20 minutes.
XMake sure that the key is in position 1or 2in
the ignition lock.
XTo switch on: press theÍbutton repeat-
edly until the desired heating level has been
set.
XTo switch off: press theÍbutton repeat-
edly until all indicator lamps go out.
If the on-board voltage is too low, the seat heat-
ing will either switch itself off prematurely or not
come on at all. In this case, too many electrical
consumers are switched on or the battery
charge is not sufficient. The seat heating will
automatically switch back to the current heating level when enough on-board voltage is available
again.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Loading guidelines
Important safety notes
GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, striking vehicle occupants. This also
applies to:
Rluggage or loads
Rseats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of a braking maneuver or abrupt change
in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove a
seat, store it preferably outside the vehicle.
GWARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and braking characteris-
tics. There is a risk of an accident.
Always make sure that the center of gravity of
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When the permissible wheel loads, axle loads
and/or the maximum permissible gross vehi-
cle weight are exceeded, driving safety is
compromised. The handling as well as steer-
ing and braking characteristics may be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is a risk of
an accident.
When transporting a load, always observe the
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (including occupants).
!If you are using a roof carrier, observe the
maximum roof load and maximum roof carrier
load.
RDo not stack luggage or loads higher than the
backrests.
RObjects to be transported should preferably
be stowed in the cargo compartment.
RWhen transporting luggage, always use the
cargo tie-down rings for securing loads and a
cargo net, if installed.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
When using suitable load securing aids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on dis-
card criteria contained therein.
Load securing aids or tie downs must not be
used if:
Ridentification marks are missing or illegible
Rthere are yarn breakages, damage to bearing seams or other signs of tearing
Rthere are signs of shearing, deformation,
pinching or other damage
Rthere is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be replaced.
If you use load securing aids or tie downs which are worn out, the load may not be sufficiently
secured and could cause damage to property.
242Loading guidelines
Transporting loads
XAlways transport loads in the cargo compart-
ment and with the seat backrests folded up
and properly locked in position.
XAlways place the load against the backrests ofthe front or rear seats.
XMove large and heavy loads as far towards thefront of the vehicle as possible against the
front or rear seats. Stow the load flush with
the rear or front seats.
XAlways additionally secure the load with suit-
able load-securing aids or tie downs.
Observe the following notes:
RDo not stack loads higher than the upper edge
of the backrests.
RTransport loads behind seats that are not
occupied.
RIf the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of the
opposite seat belt.
Cargo compartment variations
You can vary the cargo compartment according
to your transportation requirements as follows:
Rby folding the seat backrests forward to the
table position.
Rby removing the rear bench seat.
You will find information about rear bench seats in the "Rear bench seats" section (
Ypage 86).
Securing loads
Important safety notes
GWARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction, brak- ing maneuvers or an accident:
Rthe cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
Rthe load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
!Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the max-
imum loading capacity of the weakest cargo
tie-down point into account.
If you brake hard, for example, the forces act- ing could be up to several times the weight
force of the load. Always use multiple cargo
tie-down points in order to distribute the force
absorption. Load the anchorages evenly.
Spread the load evenly across the cargo tie-
down points/cargo tie-down rings. You will find information on the maximum loading capacity of
the cargo tie-down points under "Cargo tie-
down points and carrier systems" (
Ypage 312).
Do not attempt to modify or repair the cargo tie-
down points/cargo tie-down rings or tie downs.
Read the information on qualified specialist
workshops: (
Ypage 31).
As the driver, you are responsible for ensuring
that:
RThe load is secured against slipping, tipping,
rolling or falling off in normal traffic condi-
tions, should the vehicle swerve to avoid an
obstacle, in the event of full brake application
and on poor road surfaces.
RThe applicable requirements and guidelines
relating to load-securing practices must be
met.
If this is not the case, this may constitute a
punishable offense, depending on local legis-
lation and any ensuing consequences.
Always observe the legal requirements for the country you are currently in.
Make sure that the load is secure before every
journey and at regular intervals during a long
journey. Correct an incorrectly or inadequately
secured load if necessary.
Always observe the operating instructions or the
notes of the lashing strap manufacturer for the
operation of the lashing strap.
You can obtain information about securing the
load correctly from the manufacturer of the load
securing aids or tie down for securing the load.
244Securing loads
Transporting loads
GWARNING
If vehicle occupants are seated behind a load
protection net, they may be squeezed up
against the load protection net. There is a risk
of injury, particularly in the event of braking
maneuvers or abrupt changes in direction.
Never allow vehicle occupants to sit behind
the load protection net.
The load protection net borders the cargo com- partment. It protects vehicle occupants from
light objects and/or luggage slipping or tipping
over. Always observe the notes on securing
loads (
Ypage 244).
You can install the load protection net at an
angle behind the front seats or behind the first
row of back seats.
