DANG ER Risk of poisoning from exhaust
ga ses
Combustion engines emit poisonous exhaust
ga ses, such as carbon monoxide. Exhaust
ga ses can enter theve hicle interior if the
re ar-end door is open when the engine is run‐
ning, especially if theve hicle is in motion. #
Always switch off the engine before
opening there ar-end door. #
Never drive with there ar-end door
open. &
WARNING Risk of inju ryfrom unsecu red
objects in theve hicle
When objects are unsecured or inadequately
secured, they can slip, tip over or be thro wn
about, striking vehicle occupants.
This also applies to:
R Luggage or loads
R Seats which ha vebeen remo ved and are
being transpor ted in theve hicle in an
ex ceptional case
The reis a risk of injur y,particular lyin the

Before tr aveling, secure objects, lug‐
ga ge or load topreve ntthem slipping or
tipping over. #
When a seat is remo ved, keep it prefera‐
bly outside theve hicle. &
WARNING Risk of inju rydue toobjects
being stowed incor rectly
If yo u do not adequately stowobjects in the
ve hicle interior, they could slip or be tossed
around and thereby strike vehicle occupants.
In addition, cup holders, open stowage
spaces and mobile phone brac kets cannot
al wa ys restra in the objects they contain in the
eve nt of an accident.
The reis a risk of injur y,particular lyin the
eve nt of sudden braking or a sudden change
in direction. #
Alwaysstow objects in such a wayth at
th ey cannot be tossed about in these or
similar situations. #
Always make sure that objects do not
project from stowage spaces, parcel
nets or stowage nets. #
Close the loc kable stow age spaces
before starting a journe y. #
Stow and secure objects that are heavy,
hard, poin ted, sharp-edged, fragile or
to o lar geinthe cargo compartment. &
WARNING Risk of bu rns from theta ilpipe
and tailpipe trims
The exhaust tailpipe and tailpipe trims can
become very hot. If you come into con tact
wi th th ese parts of theve hicle, you could
burn yourself. #
Always be particularly careful around
th eta ilpipe and theta ilpipe trims and
supervise children especially close lyin
th is area. #
Allow vehicle parts tocool down before
to uching them. If

When securing loads, obse rveth efo llowing:
R Fill spaces between the load and the cargo
compartment walls or wheel wells. Forth is
purpose, use rigid load securing aids, such as
we dges, wooden fixings or padding.
R Attach secured and stabilized loads in all
directions.
Use the cargo tie-down points or tie-down
ey es and the loading rails in the cargo com‐
partment or on the load sur face.
Only use tie downs, such as lashing rods, lock
ro ds or lashing nets and lashing stra ps, which
has been tested in accordance with cur rent
st andards (e.g. DIN EN). Alw ays use the cargo
tie-down points closest tothe load; pad sharp
edges.
Loads, and heavy loads in particular, should
preferably be secured using the tie-down
