Driving

As the engine torque is applied to all
four wheels, the condition of the tyres
has a considerable impact on the
per formance of the vehicle.
Ensure that all four tyres are in good
condition.
Avoid driving the vehicle in sandy or
muddy areas or in other areas in which
the wheels could spin.
Spinning the wheels places the
transmission components under
pressure and could cause a serious
malfunction.
Do not drive the vehicle through deep
water.
Avoid driving over excessively uneven
terrain (risk of scraping under the body
or of grounding on crossing a bridge).


Operating faults

If the selected transmission mode display
flashes, the vehicle switches automatically to
front "2WD"
transmission mode.
It is then no longer possible to select the
transmission mode using the control A
.
If the message "SLOW DOWN" is displayed on
the instrument panel, let the transmission cool
down then wait for the display to clear before
setting off again.
If "4WD" and "LOCK" are displayed alternately
and if "SERVICE REQUIRED" is displayed in
the instrument panel, the system has failed and
the safety system has been activated.
Contact a CITROËN dealer or a qualified
workshop without delay.

Have your vehicle towed on a
flatbed.

The vehicle must not be towed with the
front or rear wheels on the ground even
if it is in front "2WD" (2 wheel drive)
mode.


If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.

Practical information

Fitting a wheel


After changing a wheel

When using the "space-saver" spare
wheel, do not exceed a speed of
50 mph (80 km/h).
Have the tightening of the bolts and the
pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.
Have the punctured wheel repaired and
replace it on the vehicle as soon as
possible.


List of operations



)
Put the wheel in place on the hub.

)
Screw in the bolts fully by hand.

)
Pre-tighten the security bolt using the
wheelbrace 1
fitted with the security
socket 5
(if your vehicle is equipped with
security wheel bolts).

)
Pre-tighten the other bolts using the
wheelbrace 1
only.


Fitting snow tyres

If you equip your vehicle with snow
tyres fitted on steel wheel rims, special
bolts available from your CITROËN
dealer or a qualified workshop must

be used.


If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.

system must always be recovered on a
flatbed.


Never have the vehicle towed with the
four wheels on the ground, this could
damage the transmission.
The vehicle must not be towed with the

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.

Playing an MP3/WMA CD

When the MP3/WMA CD is inserted in the player,
playing of the tracks is automatic.
The tracks cannot be recorded onto the music server.

You can play CDs with up to 8 levels, 255 folders and
400 fi les maximum. Windows Media and Microsoft Corporation are trademarks

General notes on MP3/WMA CDs


What is the MP3/WMA fi le format?

MP3 is the abbreviation of MPEG-1 Audio Layer 3 and MPG is the
abbreviation of Motion Pictures Experts Group, a digital video data
compression standard used on media such as video CDs.
The MP3 compression reduces the number of bytes in a song by
eliminating the long sound waves in the range of frequencies which
are imperceptible to the human ear, so producing high quality audio
fi les with a low volume of data.
This compression divides the size of the content of a conventional
audio CD by approximately 10, which means that the content of
10 audio CDs can be recorded onto a single CD-R or CD-RW.
WMA is the abbreviation of Windows Media Audio, another audio
data compression standard offered by Microsoft.
It can be used to create and save audio fi les at a compression rate
higher than that of the MP3 format.
Acceptance of the fi les

Some blank CDs may not be played by your equipment (quality,
recording speed...).
When you burn a CD-R or CD-RW, select the ISO 9660 level 1.2 or
Joliet burning standard.
To obtain the best acoustic quality possible, select the lowest
burning speed.
The MPEG1 and MPEG2 standards are accepted.
Transmission speeds between 32 and 320 kbits/s and scans
between 16 kHz and 48 kHz are accepted.
To display the title information (the name of the artist, the title of the
album, etc...), the information contained in the ID3 Tags or the WMA
Tags must be included in the MP3/WMA fi les burned onto the disc.
