Checks
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle ser vices.















Brake pads

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Brake disc wear




















Parking brake


If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two ser vices.















Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

Petrol weights and towed loads (kg)


The values for maximum towed weights type
approved according to the sales zone (see the
tables on the following pages).
The exact values are given in your vehicle's
registration document as well as on the
manufacturer's plate.
They are also mentioned in sales brochures.
For more details, contact a CITROËN dealer or
a qualified workshop.
The kerb weight is equal to the unladen
weight + driver (75 kg).
The GTW and towed load values indicated are
valid up to a maximum altitude of 1 000 metres;
the towed load mentioned must be reduced
by 10 % for each additional 1 000 metres of
altitude.
The speed of a towing vehicle must not exceed
60 mph (100 km/h) (comply with the legislation
in force in your country).
High ambient temperatures may result in a
reduction in the per formance of the vehicle to
protect the engine; if the ambient temperature
is above 37 °C, limit the towed load.

The weight of the braked trailer can be
increased, within the GTW limit, if the
GV W of the towing vehicle is reduced
by an equal amount. Please note that
towing using a lightly loaded towing
vehicle may have an adverse effect
on its road holding
.

The satellite navigation system guides the driver to the destination
set in accordance with a chosen route.
Initially, it searches for the destination required by the user, then
it calculates the route and fi nally it provides the visual and vocal
guidance instructions.

A point of interest (POI) is represented by an icon on
the map, it represents an airport, a station, a town
hall, ...
What is a point of interest (POI)?

Up to 40 different icons may be displayed (refer to the
section "Points of interest icon").
They are classifi ed in 5 groups and identifi ed by one
colour for each group:


- Shops, fi nance and businesses (Green),

- Vehicles and travel (Dark blue),

- Restaurants (Orange),

- Public places and emergency services (Brown),

- Entertainment and attractions (Blue).


GPS (Global Positioning System) consists of several
satellites arranged around the earth. They continuously
transmit digital signals which travel at the speed of
light, on 2 different frequencies.
At any given time, the system receives its position
in relation to the satellites detected and the time of
transmission of the signal.
This enables the telematic unit to calculate its position
and therefore that of the vehicle.
A repositioning process using the map database stored
on the hard disk allows the vehicle to be positioned
on the road network, so improving the accuracy of the
vehicle location function.



















GPS system


What is the navigation system and GPS?

The system's measurements may be inaccurate if the vehicle is:


- in a tunnel or underground car park,

- underneath a two-level motorway,

- in an area with several very high buildings,

- surrounded by closely planted trees.
Depending on the vehicle's situation and the reception of the GPS
information, the displayed information may disappear from the
screen temporarily.

What precautions should be observed in order to make
best use of the system?

Do not place anything on or near the GPS aerial.
Do not use any digital communication equipment (personal
computers, etc.) near the GPS aerial.
Do not affi x any refl ective fi lms or fi lms containing carbon to the
windows.

What is RDS?

The Radio Data System (RDS) function on the FM waveband permits:


- automatic retuning to alternative frequencies carrying the same
station while travelling through different regions (if the transmitters
of this station cover the area through which you are travelling),

- temporary tuning to traffi c information announcements,

- display of the name of the station, etc...

Most FM stations use RDS.
These stations transmit non-audible data in addition to their programmes.
The data transmitted in this way allows you access to various functions,
mainly displaying of the name of the station, temporary tuning to
traffi c information announcements or automatic retuning to alternative
frequencies.
RDS allows you to continue listening to the same station automatically by
means of alternative frequencies. However, alternative frequencies may not
be provided throughout the country. Radio stations do not cover the whole
country, which explains the loss of reception of the station during a journey.













RDS, AF, TP, PTY


RDS alternative frequencies


Your radio automatically checks and selects the best frequency for the radio station
to which it is tuned (if the station broadcasts on several transmitters or frequencies).
The frequency of a radio station covers approximately 30 miles (50 km). The
change from one frequency to another explains the loss of reception during a
journey.
If the station to which you are listening does not have several frequencies in the
region in which you are currently located, you can deactivate automatic alternative
frequencies.


Traffi c information function

The Traffic Programme (TP) function permits automatic and
temporary switching to an FM station broadcasting traffi c
information.
The radio station or the source that you are listening to at this point
is placed on hold.
Once the traffi c information has ended, the system switches back to
the radio station or the source that you were listening to initially.

Programme types

Some stations offer the option of listening to a themed type of
programme as a priority, selected from the list available below:
NEWS, AFFAIRS, INFOS, SPORT, EDUCATE, DRAMA, CULTURE,
SCIENCE, VARIED, POP M, ROCK M, EASY M, LIGHT M,
CLASSICS, OTHER M, WEATHER, FINANCE, CHILDREN,
SOCIAL, RELIGION, PHONE IN, TRAVEL, LEISURE, JAZZ,

Regional mode

Some stations are organised in a network.
In different regions, they broadcast different or shared programmes
depending on the time of day.
You can follow:


- a regional station only,

- the entire network, with the possibility that you will be listening
to a different programme.

"TP" traffi c information

The " Traffi c Programme
" (TP) function permits automatic
and temporary switching to an FM station broadcasting traffi c
information.
The radio station or the source that you are listening to at this point
is put on hold.
Once the traffi c information has ended, the system switches back to
the radio station or the source that you were listening to initially.

Press the TP
button.
"TP" appears in the screen. If the
station is compatible, "RDS" also
appears.

If the radio detects traffi c information, "TRAF INF" appears on the
display, followed by the frequency of the broadcasting station, then
its name.
The volume is different from that of the previous source.
Following the broadcasting of the traffi c information, the volume
returns to that of the source prior to the interruption.

When "TP" appears in the screen, the radio stops only at RDS
stations broadcasting traffi c information.
"ALERT" emergency broadcasts

An emergency broadcast automatically and temporarily interrupts
the FM station or the source that you are listening to.
The message "ALERT" appears in the screen and the volume is
different from that of the previous source.
Following the emergency broadcast, the message disappears and
the volume returns to that of the source prior to the interruption.
