GEAR SHIFT INDICATOR *

System which reduces fuel consumption
by advising the driver to change up on ve-
hicles fi tted with a manual gearbox.

*
According to engine.


Operation

The system intervenes only when driving
economically.
Depending on the driving situation and
your vehicle's equipment, the system may
advise you to skip one or more gears. You
can follow this instruction without engag-
ing the intermediate gears.
The gear engagement recommendations
must not be considered compulsory. In
fact, the confi guration of the road, the
amount of traffi c and safety remain de-
termining factors when choosing the best
gear. Therefore, the driver remains re-
sponsible for deciding whether or not to
follow the advice given by the system.
This function cannot be deactivated.
- You press the accelerator pedal
moderately.
Example:


- You are in third gear.

- The system may suggest that you
engage a higher gear, if appropriate.
The information appears in the instru-
ment panel screen in the form of an
arrow accompanied by the suggested
gear.

In the case of driving which
makes particular demands on
the performance of the engine
(fi rm pressure on the accelerator
pedal, for example, when over-
taking...), the system will not rec-
ommend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

DRIVING

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 acceler-
ating 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 buttons 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 vehicle,
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).

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.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.

CHECKS
179
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 corre-
sponding system checked by a CITROËN
dealer or a qualifi ed workshop.

When working under the bon-
net, 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 igni-
tion is switched on using the oil level indicator
in the instrument panel, or using the dipstick.

Oil level


Engine oil change
Refer to the Maintenance and Warranty
Guide 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 Maintenance and Warranty
Guide 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 igni-
tion 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.
