Characteristics of the
engines and towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact the dealer
network or a qualified workshop.
Weights and towed loads
The maximum weights and towed loads for
your vehicle are given in the registration
document, as well as in sales brochures.
These values are also given on the
manufacturer's plate or label.
For more information, contact the dealer
network or a qualified workshop.
The GTW and towed load values indicated are
valid up to a maximum altitude of 1,000 metres.
The towed load value must be reduced by 10%
for each additional 1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball (which can be dismantled with or
without a tool).
GT W: Gross train weight. High exterior temperatures may result
in a reduction in the per formance of
the vehicle to protect the engine. If the
exterior temperature is above 37°C, limit
the towed load.
Towing with a towing vehicle which is only
slightly laden may negatively affect its
handling.
Towing a trailer increases the braking
distance.
When towing, never exceed the speed
of 62 mph (100 km/h) (obser ve the local
legislation in force).

Navigation
QUESTIONRESPONSE SOLUTION
The route calculation is not
successful. The guidance criteria may be in conflict with the current
location (exclusion of toll roads on a toll road). Check the route settings in the "Navigation" menu.
The POIs do not appear. The POIs have not been selected. Select the POIs in the list of POIs.
The audible warning of "Danger
areas" does not work. The audible warning is not active or the volume is too
low. Activate the audible warning in the "Navigation" menu
and check the voice volume in the audio settings.
The system does not suggest
a detour around an incident on
the route. The guidance criteria do not take account of TMC
messages.
Select setting for the "Traffic info" function in the list of
route settings (Without, Manual or Automatic).
I receive a "Danger zone" alert
which is not on my route. Other than guidance, the system announces all "Danger
zones" positioned in a cone located in front of the
vehicle. It may provide an alert for "Danger zones"
located on nearby or parallel roads. Zoom
in on the map to see the exact position of the
"

Danger zone". Select "On the route" to no longer
receive alerts other than navigation instructions or to
reduce the time for the announcement.
Certain traffic jams along the
route are not indicated in real
time. On starting, it is several minutes before the system
begins to receive the traffic information.
Wait until the traffic information is being received correctly
(display of the traffic information icons on the map).
In certain countries, only major routes (motor ways...) are
listed for the traffic information.
This is per fectly normal. The system is dependent on
the traffic information available.
The altitude is not displayed. On starting, the initialisation of the GPS may take up to 3 minutes to receive more than 4 satellites correctly. Wait until the system has started up completely so that
there is GPS coverage by at least 4
satellites.
Depending on the geographical environment (tunnel...)
or the weather, the conditions of reception of the GPS
signal may vary. This behaviour is normal. The system is dependent on
the GPS signal reception conditions.
My navigation is no longer
connected. During start-up and in certain geographical areas, the
connection may be unavailable. Check that the connected ser vices are activated
(settings, contract).

Radio
QUESTIONRESPONSESOLUTION
The reception quality of the tuned radio station
gradually deteriorates or the stored stations are
not working (no sound, 87.5 Mhz is displayed...).The vehicle is too far from the transmitter of
the station or no transmitter is present in the
geographical area.Activate the "RDS" function by means of the
short-cut menu to enable the system to check
whether there is a more power ful transmitter in
the geographical area.
The environment (hills, buildings, tunnels,
basement car parks...) block reception, including
in RDS mode. This phenomenon is normal and does not
indicate a failure of the audio equipment.
The aerial is absent or has been damaged (for
example when going through a car wash or into
an underground car park). Have the aerial checked by a dealer.
I cannot find some radio stations in the list of
stations received.
The name of the radio station changes. The station is not received or has changed its
name in the list.
Some radio stations send other information
in place of their name (the title of the song for
example).
The system interprets these details as the
station name.Press on the "Update list" button in the "Radio
stations" secondary menu.
