Loading information
■ Heavy objects in the load compartment should be placedagainst the seat backrests. Make
sure that the backrests are securely engaged, i.e. no longer showing the
red markings on the side near the release lever. If objects can be
stacked, heavier objects should be
placed at the bottom.
■ Secure objects with lashing straps attached to lashing eyes 3 73.
■ Secure loose objects in the load
compartment to prevent from
sliding.
■ When transporting objects in the load compartment, the backrests of
the rear seats must not be angled
forward.
■ Do not allow the load to protrude above the upper edge of the
backrests.
■ Do not place any objects on the load compartment cover or theinstrument panel, and do not cover
the sensor on top of the instrument panel.
■ The load must not obstruct the operation of the pedals, parking

Storage819Warning
Always make sure that the load in
the vehicle is securely stowed.
Otherwise objects can be thrown
around inside the vehicle and
cause personal injury or damage
to the load or car.
■ The payload is the difference between the permitted gross
vehicle weight (see identification
plate 3 264) and the EC kerb
weight.
To calculate the payload, enter the
data for your vehicle in the Weights
table at the front of this manual.
The EC kerb weight includes
weights for the driver (68 kg),
luggage (7 kg) and all fluids (tank
90 % full).
Optional equipment and
accessories increase the kerb
weight.
■ Driving with a roof load increases the sensitivity of the vehicle to
cross-winds and has a detrimental
effect on vehicle handling due to
the vehicle's higher centre of
gravity. Distribute the load evenly
and secure it properly with retaining
straps. Adjust the tyre pressure and vehicle speed according to the load
conditions. Check and retighten the straps frequently.
Do not drive faster than 120 km/h.
The permissible roof load is
100 kg. The roof load is the
combined weight of the roof rack
and the load.

258Vehicle care
If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wiper and rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle
regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Do not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.Plastic body parts must not be treated with wax or polishing agents.
Windows and windscreen wiper blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Sunroof Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.
