The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the
driver to take risks or to drive at high
s p e e d .
The operation of these systems is
ensured if the recommendations

Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually. P l e a s e c o n t a c t a C I T R O Ë N d e a l e r fi r s t
for further information .
Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
s p e e d t o b e s i g n i fi c a n t l y i n c r e a s e d
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.
Lighting
Bicycle carrier
R e f e r t o t h e " I d e n t i fi c a t i o n
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.
If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.
Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
T o w i n g e q u i p m e n t m u s t b e fi t t e d i n
accordance with the manufacturer’s
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
t h e e l e c t r i c a l c o n n e c t i o n . A s t h i s fi t t i n g
should be carried out by a professional,
we recommend that you entrust the

In accordance with the general
instructions referred to above, we draw
your attention to the risk connected

accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure of
your vehicle’s electronic system. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.

These regular maintenance
operations will keep your vehicle
in good running order. Consult the
instructions at CITROËN dealerships
or in the servicing booklet enclosed in
the handbook pack. To maintain the reliability of engines
and emission control systems, the use
of additives in engine oil is prohibited.

Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
Viscosity selection
In all cases, the oil selected must meet
the manufacturer's requirements. Checking by means of the
warning lights on the instrument
panel is described in chapter 2,
"Instruments and controls" section.

the manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
I f fl u i d h a s t o b e a d d e d f r e q u e n t l y ,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.
Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks. During regeneration of the particle

products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.

CHECKS
To check the main levels
and certain components,
in accordance with the
manufacturer's servicing schedule,
refer to the pages of the Maintenance
and Warranty Guide which correspond
to your vehicle's engine.
Only use products recommended
by CITROËN or products
of equivalent quality and
s p e c i fi c a t i o n .
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers
s p e c i fi c p r o d u c t s .
In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is
strictly prohibited.

Depending on the environment
(dusty atmosphere...) and the use of

On acceleration after the vehicle has
been running for a prolonged period
at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust. This water vapour does not
have any adverse effect on vehicle
handling or the environment. Battery
At the start of winter, have your battery
checked by a CITROËN dealer.
Brake pads
Brake pad wear depends on the style
of driving, in particular for vehicles
which are used in town, over short
distances. It may be necessary to
check the thickness of the pads, even
between services.
Unless there is a leak on the circuit, a

Brake disc/drum wear status
For any information relating to
checking the brake disc/drum wear
status, contact a CITROËN dealer.
Handbrake
Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
