Always transport loads in the cargo com-
partment and with the seat backrests folded
up and properly locked in position.
X Always place the load against the backrests
of the front or rear seats.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the front or rear seats. Stow the load flush
with the rear or front seats.
X Always additionally secure the load with
suitable load-securing aids or tie downs.
Observe the following notes:
R Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If 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 accord-
ing to your transportation requirements as fol-
lows:
R by folding the seat backrests forward to the

Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction,
braking maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the 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
maximum loading capacity of the weakest
cargo tie-down point into account.
If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to distrib-
ute the force absorption. Load the ancho-
rages evenly.
As the driver, you are responsible for ensuring
that: R The 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 maximum full-stop
braking and on poor road surfaces
R The applicable requirements and guidelines
relating to load-securing practices are met
If this is not the case, this may constitute a
punishable offense, depending on local leg-
islation 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. Also observe the safety information in
the loading directions ( Y page 242).

from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the
brake fluid is too low, vapor pockets may
form in the brake system when the brakes
are applied hard. This would impair braking
efficiency. There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immediately
for leaks. Also check the thickness of the
brake linings. Visit a qualified specialist
