Loading guidelines
GWARNING
If objects, luggage or loads are not secured
or not secured sufficiently, they could slip,
tip over or be flung around and thereby hit
vehicle occupants. There is a risk of injury,
particularly in the event of sudden braking
or a sudden change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the tailgate is open while the engine is
running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. Never drive with the tailgate
open.
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could
burn yourself. There is a risk of burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
The handling characteristics of a laden vehicleare dependent on the distribution of the loadwithin the vehicle.
Observe the following notes when loading andtransporting a load:
RNever exceed the maximum permissiblegross vehicle mass or the gross axle weightrating for the vehicle (including occupants).The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver'sdoor.
RThe cargo compartment is the preferredplace to carry objects.
RPosition heavy loads as far forward as possi-ble and as low down in the cargo compart-ment as possible.
RThe load must not protrude above the upperedge of the seat backrests.
RAlways place the load against the rear orfront seat backrests. Make sure that theseat backrests are securely locked intoplace.
RAlways place the load behind unoccupiedseats if possible.
RUse the cargo tie-down rings and the parcelnets to transport loads and luggage.
RUse cargo tie-down rings and fasteningmaterials appropriate for the weight andsize of the load.
RThe maximum load capacity of the stowagewell under the cargo compartment floor is55 lbs(25 kg).
RSecure the load with sufficiently strong andwear-resistant tie-downs. Pad sharp edgesfor protection.
!Do not position the load on one part of thefolding cargo compartment floor only. Themaximum load capacity of the folding cargocompartment floor is 220 lbs(100 kg). Dis-tribute theweight evenly to avoid damagingthe cargo compartment floor. Place a solidboard under the load if necessary. Pleasenote that the load on the cargo compart-ment floor will be increased when the loadis lashed down.

Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up
when the vehicle is in motion and block your
view. There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There
is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one
is within its range of movement.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off.
There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system and the fuel injection
system work under high voltage. If you
touch components which are under voltage,
you could get an electric shock. There is a
risk of injury.
Never touch components of the ignition sys-
tem or fuel injection system when the igni-
tion is switched on.
To ensure the flow of fresh air through the airvents into the vehicle interior, please observethe following notes (Ypage 123):
Opening the hood
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
