Reactivation
By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
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 action
the accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A fl a s h e s .
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
t h e n t h e s p e e d fl a s h e s . A d a p t y o u r
speed as necessary.

crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a di-

PNEUMATIC SUSPENSION
Grand C4
Picasso
C4 Picasso
The rear pneumatic suspension en-
hances driving comfort by maintain-
ing a constant body height whatever
the vehicle load. Operation
- If there is an increase in vehi-
cle load, a sinking of the rear of
the vehicle is detected and the
p n e u m a t i c s p r i n g s i n fl a t e i n o r -
der to compensate for the extra
weight.
- If there is a decrease in load, a rising of the rear of the vehicle is
detected and so the pneumatic

The oil must correspond to your
engine and conform to the manufac-
turer's recommendations.

Coolant level
Draining the circuit
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
15 minutes.
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.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. 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 tem-
perature of the coolant is regulated
by the fan. This can operate 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,
unscrew the cap by two turns to
allow the pressure to drop. When
the pressure has dropped, remove
the cap and top up the level.
In order to maintain the
reliability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and in
relation to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not
require any maintenance.
However, check that the
terminals are clean and
correctly tightened, parti-
cularly in summer and winter.
When carrying out work on the bat-
t e r y , r e f e r t o t h e " P r a c t i c a l i n f o r -

precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
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" paragraph).

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
notice water vapour being emitted
from the exhaust when accelerat-
ing. 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 a sound
signal and lighting of the service
warning lamp.

Brake pads Brake wear depends on
the style of driving, par-
ticularly 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 circuit, a

The gearbox does not
require any maintenance
(no oil change).
6-speed electronic gearbox
system
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change). Brake disc wear status
For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.
Handbrake
If the handbrake travel is too long
or if a loss of effectiveness of this
system is noticed, the handbrake
must be adjusted, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent quality

In order to optimise the operation
of units as important as the braking
system, CITROËN selects and

To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
