BLIND SPOT SENSORS


This driving assistance system warns
the driver of the presence of another
vehicle in the blind spot angle of their
vehicle (areas masked from the driver's
fi eld of vision), as soon as this presents
a potential danger.

Operation





On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.

This system is designed to im-
prove safety when driving and is
in no circumstances a substitute
for the use of the interior rear
view mirror and door mirrors. It
is the driver's responsibility to
constantly check the traffi c, to
asses the distances and relative
speeds of other vehicles and to
predict their movements before
deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers monitor the blind spots. A warning lamp appears in the door
mirror on the side in question:


- immediately, when being overtaken,

- after a delay of about one second,
when overtaking a vehicle slowly.

SPEED LIMITER
System which prevents the vehicle
from exceeding the speed programmed
by the driver.
When the programmed speed limit is
reached, pressing the accelerator ped-
al no longer has any effect.
The speed limiter cannot, in any
circumstances, replace the need
to respect speed limits, nor can
it replace the need for vigilance
and responsibility on the part of
the driver. The functions of this system are
grouped together on the steering
mounted controls.

Operation

The speed limiter is switched on
man-
ually: it requires a programmed speed
of at least 20 mph (30 km/h).
The speed limiter is switched off
by
manual operation of the control.
The programmed speed can be ex-
ceeded temporarily by pressing the
accelerator fi rmly beyond the point of
resistance.
To return to the programmed speed,
simply release the accelerator pedal.
The programmed speed remains in the
memory when the ignition is switched
off.

Programming




Turn dial 1
to the "LIMIT"
posi-
tion: the speed limiter mode is
selected but is not switched on
(Pause).
You do not have to switch the speed
limiter on in order to set the speed.



Set the speed value by pressing button 2
or 3
(e.g.:
55 mph (90 km/h)).
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 speed memorisation is available and activated on your
vehicle, the programmed speed will stop at the closest
memorised speed; refer to the corresponding paragraph.



Switch the speed limiter on by pressing button 4
.


Switch the speed limiter off by pressing button 4
: the
display confi rms that it has been switched off (Pause).


Exceeding the programmed speed

Pressing the accelerator pedal to exceed the programmed
speed will not have any effect unless you press the pedal
fi rmly
past the point of resistance
.
The speed limiter is deactivated temporarily and the pro-
grammed speed, which is still displayed, fl ashes.
Returning to the programmed speed, by means of inten-
tional or unintentional deceleration of the vehicle, automati-
cally cancels the fl ashing of the programmed speed.


Exiting the speed limiter mode




Turn dial 1
to the "0"
position: the
speed limiter mode is deselected. It
disappears from the screen.



Operating fault

In the event of a fault with the speed
limiter, the speed is cleared resulting in
fl ashing of the dashes.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
On a steep descent or in the
event of sharp acceleration, the
speed limiter will not be able to
prevent the vehicle from exceed-
ing the programmed speed.
To avoid any risk of jamming of
the pedals:


- ensure that the mat is posi-
tioned correctly,

- do not fi t one mat on top of
another.


Switch the speed limiter back on by pressing button 4

again.

The cruise control system can-
not, in any circumstances, re-
place the need to respect speed
limits, nor can it replace the need
for vigilance and responsibility
on the part of the driver.
You are advised to keep your
feet near the pedals at all times.






CRUISE CONTROL

hicle speed of 25 mph (40 km/h) and
engagement of:


- fourth gear on the manual gearbox,

- second gear on the electronic gear-
box system or automatic gearbox,
in sequential driving mode,

- position A
on the electronic gearbox
system or D
on an automatic gear-
box.
The cruise control is switched off
man-
ually or by pressing the brake or clutch
pedal or on triggering of the ESP sys-
tem for safety reasons.
It is possible to exceed the programmed
speed temporarily by pressing the ac-
celerator pedal.

When the cruise control is
switched on, be careful if you
maintain the pressure on one of
the programmed speed changing
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.

PARKING SENSORS

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
which comes within the fi eld of detection
of sensors located in the bumper.
Certain types of obstacle (stake, road-
works cone, etc.) detected initially will
no longer be detected at the end of the
manoeuvre due to the presence of blind
spots.

This function cannot, in any cir-
cumstances, take the place of
the vigilance and responsibility
of the driver.
The system is switched on by engaging
reverse gear. This is accompanied by
an audible signal.
The system is switched off when you
exit reverse gear.

Rear parking sensors


Audible assistance
The proximity information is given by an
intermittent audible signal, the frequen-
cy of which increases as the vehicle ap-
proaches the obstacle.
The sound emitted by the speaker (right
or left) indicates the side on which the
obstacle is located.
When the distance between the vehicle
and the obstacle becomes less than
approximately thirty centimetres, the
audible signal becomes continuous.


Visual assistance
This supplements the audible signal
by displaying bars in the multifunction
screen which move progressively near-
er to the vehicle. When the obstacle is
near, the "Danger" symbol is displayed
in the screen.

CHECKING LEVELS


Take care when working under
the bonnet, as certain areas of
the engine may be extremely hot
(risk of burns) and the cooling
fan could start at any time (even
with the ignition off).


The check is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel, or us-
ing the dipstick.
It will only be correct if the vehicle is on
level ground and the engine has been
off for more than 30 minutes.
It is normal to top up the oil level be-
tween two services (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping up.


















Oil level


Engine oil change
Refer to the maintenance and warranty
guide for details of 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.











Brake fluid level


Changing the fl uid
Refer to the maintenance and warranty
guide for details of the interval for this
operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations.












Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold, un-
screw the cap 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.
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.

Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Check all of these levels regularly, in
line with the maintenance and warranty
guide. Top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.








The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might become caught by the
fan blades.
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
