restraint.
With fitted protective cover the
maximum load on each of the folded
backrests is 100 kg.
Warning triangle
Depending on version, the warning
triangle can be stowed in the load
compartment. Secure it with the
elastic straps.
First aid kit
Depending on version, the first aid kit can be stowed in the load

Roof rack system
Roof rack
For safety reasons and to avoid
damage to the roof, the vehicle
approved roof rack system is
recommended. For further
information contact your workshop.
Follow the installation instructions
and remove the roof rack when not in use.
Mounting roof rack
Vehicles with roof railing
Storage87Mounting points are located at the
bottom of the roof railing.
Fasten the roof rack according to the
installation instructions delivered with
the roof rack.
Vehicles without roof railing
To fasten a roof rack, unscrew the
caps in the roof strips. Insert the
mounting provisions, as instructed, in the retainer.
Loading information
● Heavy objects in the load compartment should be placed
against the seat backrests. Make
sure that the backrests are
securely engaged. If objects can
be stacked, heavier objects
should be placed at the bottom.
● Prevent sliding of loose objects by securing them with straps
attached to the lashing eyes
3 80.
● Do not allow the load to protrude above the upper edge of the
backrests.
● Do not place any objects on the rear luggage cover or the
instrument panel, and do not cover the sensor on top of theinstrument 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 3 257) and the EC kerb
weight.
88StorageTo 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 120 km/h.
The permissible roof load is:● 80 kg for vehicles with roof railing
● 100 kg for vehicles without roof railing and with two roofracks
● 150 kg for vehicles without roof railing and with three
roof racks, except vehicles
with seven seats
● 100 kg for vehicles without roof railing and with three
roof racks and seven seats
The roof load is the combined weight
of the roof rack and the load.

Driving and operating179● The electric parking brake isapplied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control.
Switching off the system
Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
184Driving and operatingEmergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash.
● Automatic transmission: If the vehicle comes to a completestop, automatic braking is
maintained for up to two
seconds. Keep the brake pedal
depressed to prevent the vehicle
from starting off again.
● Manual transmission: If the vehicle comes to a complete
stop, the engine may stall.
Operation of the function may be felt
by a slight vibration in the brake
pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
System limitations
In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● Driving on winding or hilly roads.
● Detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● Detecting a vehicle when weather limits visibility, such as infog, rain, or snow.
● Driving during nighttime.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
We recommend to deactivate the system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lamps are not working
