instrument panel.
Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed

You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again. Return to normal driving
By moving the control 1 from po-
sition "LIM" to position 0 .
By the engine stopping.
The speed previously chosen is still
memorised. Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
a c c e l e r a t i o n ) t h e n t h e s p e e d fl a s h e s .
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
U s e o f fl o o r m a t s t h a t a r e n o t a p -
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing of the speed limiter.
To avoid any risk of interfering with
the pedals:

If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.
By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display.
Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-

BONNET
Opening
At the front of the bonnet, push
the exterior safety catch B to the
left and raise the bonnet.
Unclip the stay C from its housing.
Fix the stay in the notch to hold
the bonnet open. Closing
Take the stay out of the support
notch.
Clip the stay in its housing.
Lower the bonnet then slam it
closed at the end of its travel.
Pull on the bonnet to check that
it is fully closed.
The location of the interior release
lever prevents opening of the bon-
net while the left hand door is
closed.
This operation must only be carried
out when the vehicle is stationary.
Avoid opening the bonnet in strong
winds.
When the engine is hot, take care
when handling the exterior safety
catch and the bonnet stay (risk of
burns).
Open the left hand front door.
Pull the interior release lever A ,
located at the bottom of the door
frame. Before doing anything un-
der the bonnet, switch off
the Stop & Start system
to avoid any risk of injury result-
ing from an automatic change to
START mode.

Coolant level
Changing the coolant
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
1 5 m i n u t e s .
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick. T h e b r a k e fl u i d l e v e l s h o u l d
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
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 oper-
ate with the ignition off.

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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited. When working under the
bonnet, take care, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fluid level T h e p o w e r s t e e r i n g fl u i d

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection. Air filter and passenger
compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
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
(refer to the "Engines" section).

contribution to the preservation of air
quality by the retaining of the unburnt
pollutant particles. Black exhaust
fumes are thus no longer emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the service
warning lamp.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles 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 circuit, a
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s

For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.
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.
For more information, see "Driving -
