Servicing the ventilation and air
conditioning system
►
Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly
.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).

Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.

slope, for example), an audible signal triggers
immediately
.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
If necessary, use the brakes to control the
speed of your vehicle.
Once the speed of the vehicle returns to the
speed setting, the speed limiter resumes
operation: the display of the speed setting
becomes fixed again.
