Manual gear changing
In the automated mode, you can take over
control temporarily at any time using the
steering mounted controls.
The use of these controls permits manual
selection of the gears in situations which
require a faster change down than that offered
in automated mode (arrival at a roundabout,
exit from a car park with a steep gradient,
over taking...).
The gearbox engages the gear requested if
the engine speed permits it. The gear engaged
appears.
To return to the automated mode, do one of the
following:
-
p
ress the back of the "+/OFF" steering
mounted control 3 for approximately
2
seconds,
-

m
ove the gear lever quickly towards
position +/- and then return it to position D ,
-

s
top the vehicle.
Stopping the vehicle Operating fault
With the ignition on, if the message "Slow
down" or "Service required" appears in
the instrument panel screen, this indicates a
gearbox malfunction.
When a message is displayed, carry out the
following operations:
-

s
low down and stop your vehicle in a safe
place,
-

p
lace the lever in position P and let the
engine run,
-

o
pen the bonnet to allow the engine to
cool.
If the message disappears for a long period,
you can set off again.
If the message remains displayed or appears
frequently, contact a CITROËN dealer or a
qualified workshop without delay.
Before switching off the engine, you must place
the gear lever in position P
.
You must apply the parking brake to immobilise
the vehicle.

The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
Under-inflation detection
System which continuously and automatically checks the pressures of the four tyres after switching on the ignition.
A pressure sensor is located in the valve of each tyre (except the spare wheel).
The system triggers an alert if a drop in pressure is detected in one or more tyres, compared to the reference pressure registered in the system.
This reference pressure must be reinitialised every time the tyre pressures are adjusted or a wheel changed.
The system operates on condition that sensor identifiers have first been memorised in the system by a CITROËN dealer or a qualified workshop.
You can memorise two sets of tyres (for example: wheels with "standard" tyres and wheels with "winter" tyres).
Driving with under-inflated tyres
increases fuel consumption.This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.

Managing sets of tyres
If you have had a second set of tyres registered
by a CITROËN dealer or a qualified workshop,
every time you change the set of tyres (fitting
a set of winter tyres, for example), you must
select the set you have just fitted in the
configuration menu.After fitting the new set of tyres, you
should check and adjust the tyre
pressures to the values specified
on the tyre pressure label (see the
"Identification markings" section). Selection of the other set of tyres is is done via
the menu screen, with the ignition on and the
vehicle stationary.
F

P
ress repeatedly on the INFO button to
select the menu for managing sets of tyres
(located in menu 3/3) .
F Press and hold the INFO button for at least
3 seconds to change successively from
set of tyres 1 to set of tyres 2 or the other
way round. The system automatically reinitialises
the reference pressure based on the
pressure in the new set (the under-
inflation detection warning lamp flashes
during the operation).

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Oil level
The check of the the level is done
out with the dipstick, located under
the bonnet. Refer to the description
of your engine compartment for the
position of the dipstick.Engine oil change
Refer to the maintenance and warranty guide
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Oil specification
The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum
If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check will only be correct if the vehicle is
on level ground and the engine has been off for
more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once
a
month.
When carrying out work on the battery, refer
to "12V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.
Unless other wise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.

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 traffic 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 traffic 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. 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 dif

ferent programme.
RDS, AF, REG, TP, PTY
RADIO
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. Traffic information function
The Traf
fi c Programme (TP) function permits automatic and
temporary switching to an FM station broadcasting traffic
information.
The radio station or the source that you are listening to at this point
is paused.
Once the traffic information has ended, the system switches back to
the radio station or the source that you were listening to initially .
