Storage71Roof rack system
Roof rack For safety reasons and to avoiddamage to the roof, the vehicle-
approved roof rack system is
recommended.
Follow the installation instructions
and remove the roof rack when not in
use.
Mounting roof rack
Open all doors.
Mounting points are located in each
door frame of the vehicle body.
Detach the cover from each mounting
point and fasten the roof rack with the attached screws.Loading information
● Heavy objects in the load compartment should be placed
against the seat backrests. Make
sure that the backrests are
securely engaged, i.e. no longer
showing the red marks on the side near the release lever or on
the loop. If objects can be
stacked, heavier objects should
be placed at the bottom.
● Secure objects with lashing straps attached to lashing eyes
3 69.
Page 74 of 255

72Storage● Secure loose objects in the loadcompartment 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 the
instrument panel, and do not cover the sensor on top of the
instrument panel.
● The load must not obstruct the operation of the pedals, parking
brake and gear selector, or
hinder the freedom of movement of the driver. Do not place any
unsecured objects in the interior.
● Do not drive with an open load compartment.9Warning
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 3 227) 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 (fuel
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 75 mph.
The permissible roof load is
60 kg. The roof load is the
combined weight of the roof rack and the load.
