DRIVING
174
When the cruise control is
switched on, be careful if you
maintain the pressure on one of
the programmed speed chang-
ing buttons: this may result in a
very rapid change in the speed
of your vehicle.
Do not use the cruise control on
slippery roads or in heavy traffi c.
On a steep descent, the cruise
control will not be able to prevent
the vehicle from exceeding the
programmed speed.
On steep climbs or when towing,
the programmed speed may not
be reached or maintained.
To avoid any risk of jamming of
the pedals:
- ensure that the mat is posi-
tioned correctly,
- never fi t one mat on top of
another.
Programming
)
Turn dial 1
to the "CRUISE"
po-
sition: the cruise control mode is
selected but is not switched on
(Pause).
)
Set the programmed speed by ac-
celerating to the required speed,
then press button 2
or 3
(e.g.:
70 mph (110 km/h)); the cruise
control system is activated (ON).
You can then change the programmed speed using but-
tons 2
and 3
:
- by + or - 1 mph (km/h) = short press,
- in steps of + or - 5 mph (km/h) = maintained press.
If storing speeds is available and activated on your vehi-
cle, the programmed speed will stop at the closest stored
speed; refer to the corresponding section.
)
Stop the cruise control system by pressing button 4
:
this is confi rmed in the screen (Pause).
Exceeding the programmed speed
Intentional or unintentional exceeding of the programmed
speed results in fl ashing of this speed in the screen.
Return to the programmed speed, by means of intentional
or unintentional deceleration of the vehicle, automatically
cancels the fl ashing of the speed.
Exiting cruise control mode
)
Turn dial 1
to the "0"
position: the cruise control mode
is deselected. It disappears from the screen.
)
Switch on the cruise control again with another press
on button 4
.
Operating fault
In the event of a cruise control malfunc-
tion, the speed is cleared resulting in
fl ashing of the dashes.

CHECKS
184
CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.
When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).
Oil level
Engine oil change
Refer to the servicing booklet for the
interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's rec-
ommendations.
Brake fluid level
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
Refer to the servicing booklet for the
interval for this operation.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Power steering fluid level
The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.
Coolant level
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.
On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
Changing the coolant
The coolant does not have to be
changed.
Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Electric parking brake
This system does not require any
routine servicing. However, in
the event of a problem, have the
system checked by a CITROËN
dealer or a qualifi ed workshop.
For more information, see "Driving - Electric parking brake - § Operating faults".
Brake pads
Brake disc wear
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.
In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.
Manual parking brake
For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. 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 services.
Unless there is a leak in the system, a drop
in the brake fl uid level indicates that the
brake pads are worn.

CHANGING A BULB
The headlamps are fi tted with
polycarbonate glass with a pro-
tective coating:
)
do not clean them using a
dry or abrasive cloth, nor
with a detergent or solvent
product,
)
use a sponge and soapy water,
)
when using a high pressure
washer on persistent marks,
do not keep the lance direct-
ed towards the lamps or their
edges for too long, so as not
to damage their protective
coating and seals.
)
Do not touch the bulb directly
with your fi ngers, use lint-
free cloths.
Changing a bulb should only be
done after the headlamp has been
switched off for a few minutes (risk
of serious burns).
It is imperative to use only anti-
ultraviolet (UV) type bulbs in
order not to damage the head-
lamp.
Always replace a failed bulb with
a new bulb with the same type
and specifi cation.

TOWING A TRAILER,
A CARAVAN, ETC.
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions. The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.
Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed loads
which apply to your vehicle.
Side wind
)
Take into account the increased
sensitivity to side wind.
Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.
)
To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.
)
If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.
Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.
Tyres
)
Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
)
Check the electrical lighting and sig-
nalling on the trailer.
