HILL START ASSIST
System which keeps your vehicle
immobilised temporarily (approxi-
mately 2 seconds) when starting on
a gradient, the time it takes to move
your foot from the brake pedal to the
accelerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in certain conditions on a gradi- ent,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation

On an ascending
gradient
, with
the vehicle stationary, the vehicle
is held for a brief moment when
you release the brake pedal:
- provided you are in fi rst gear or neutral on a manual gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending
gradient
, with
the vehicle stationary and reverse
gear engaged, the vehicle is held
for a brief moment when you re-
lease the brake pedal.
Do not exit the vehicle while
it is being held in the hill start
assist phase.
If you need to exit the vehicle
with the engine running, manually
apply the parking brake and en-
sure that the parking brake warning
lamp (on the instrument panel) and
the warning lamp P (on the control
lever A ) are permanently on.

GEAR ECONOMY INDICATOR *
System which reduces fuel con-
sumption by advising the driver to
change up on vehicles fi tted with a
manual gearbox.
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 engaging the in-
termediate gears.
The gear engagement recommen-
dations must not be considered
compulsory. In fact, the confi gu-
ration of the road, the amount of
traffi c and safety remain determin-
ing factors when choosing the best
gear. Therefore, the driver remains
responsible for deciding whether or
not to follow the advice given by the
system.
This function cannot be deactivated.
* According to engine. Example:
- You are in third gear.
- You press the accelerator pedal
moderately.
- The system may suggest that you engage a higher gear, if ap-
propriate. The information appears in the in-
strument panel screen in the form of
an arrow accompanied by the sug-
gested 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 overta-
king...), the system will not recom-
mend a gear change.
The system never suggests:
- engaging fi rst gear,
- engaging reverse gear,
- engaging a lower gear.

Never select positions P or R
if the vehicle is not stationary.
If, while the vehicle is moving, po-
sition N is engaged inadvertently,
allow the engine to idle before en-
gaging position D or M .
Moving off

 To start the engine, the gear le-
ver must be in position P or N .

 Operate the starter.

 When the engine is running,
place the gear lever on R , D or

M as required.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and ac-
celerate.

 To avoid a possible difference
between the position of the gear
lever and the actual position of
the gearbox, always exit from
position P with the ignition on
and brake pedal applied.
Otherwise, when the ignition is on or
the engine is running:

 reposition the gear lever in posi-
tion P ,

 put your foot on the brake pedal
and then select the gear you
want. Park
This position of the gear le-
ver is used to prevent the
vehicle from moving when
you are stationary.

 To select position P , move the
gear lever back to the highest
position (towards R ), then push
it forwards and then to the left.

 To exit position P , move the gear
lever to the right and then to the
position you want.

 Only engage this position when
the vehicle is completely sta-
tionary. In this position, the front
wheels are locked. Make sure
that the gear lever is correctly
positioned. Reverse gear
Only engage this position
when the vehicle is station-
ary. To prevent snatching,
do not accelerate too soon
after selection.
Neutral Never select position N if
the vehicle is moving.

Automatic operation

 Move the gear lever to position D .
The gearbox constantly selects the gear that is best suited to the
following parameters:
- driving style,
- road profi le
- vehicle load.
The gearbox operates without requir-
ing any intervention on your part.
For certain manoeuvres (for ex-
ample overtaking), you can obtain
maximum acceleration by pressing
the accelerator pedal hard down
past the point of resistance, which
then produces an automatic change
down to a lower gear. When braking, the gearbox may
change down automatically in order
to provide effective engine braking.
If you lift your foot off the accelera-
tor abruptly, the gearbox will not en-
gage a higher gear.
Manual operation
Position of the gear lever for manual
gear changing.

 Move the gear lever to position M .

 Push the gear lever towards the
" + " sign to change up a gear.

 Pull the gear lever towards the
" - " sign to change down a gear. - If the vehicle stops or reduces
speed (for example when ap-
proaching a stop sign), the gear-
box changes down automatically
to fi rst gear.
- In sequential mode, it is not nec- essary to release the accelerator
during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it.
- The SPORT and SNOW modes
do not operate in sequential
mode.

slippery roads.
This programme makes moving off
easier and improves traction in con-
ditions of poor grip.

 appears on the instru-
ment panel.
The gearbox automatically favours a
dynamic driving style.

S appears on the instrument panel. Return to automatic operation

 At any time, press the button se-
lected again to exit from the pro-
gramme engaged and return to
auto-adaptive mode. A strong snatch may be felt
when selecting
R for reverse
gear.
In the event of a malfunction, the
gearbox is blocked in one gear;
do not exceed a speed of 62 mph
(100 km/h).
Do not turn off the engine while the
gear selector is in position D or R .
Never press the accelerator and
brake pedals simultaneously.
Braking and acceleration should
be done with the right foot only.
Pressing both pedals simultane-
ously may damage the gearbox.
Consult a CITROËN dealer.

SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
When the limit speed is reached, the
accelerator pedal no longer has any
effect.
The speed limiter is switched
on manually: a speed of at least
20 mph (approx. 30 km/h) must be
programmed.
The speed limiter can in no way re-
place respect for speed limits or vigi-
lance and responsibility on the part
of the driver.
Steering mounted controls

D R I V I N G
In the event of a steep descent or
under excessive acceleration, the
speed limiter (which does not act
on the brakes) may not be able to
prevent the vehicle from exceeding
the programmed speed.
Use of a fl oor mat other than that
recommended by CITROËN may
affect the normal operation of the
accelerator pedal and hamper the
operation of the speed limiter.
Floor mats approved by CITROËN
are fi tted with a 3rd fi xing located in
the pedal area to avoid any risk of
interference with the pedals.
Suspension/Resumption

 Press on button 3 .
This action causes the information

"PAUSE" to appear in zone A of the
instrument panel.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel. Overriding the programmed
speed
The accelerator pedal has an end-
of-travel switch. In order to exceed
the memorised maximum speed at
any time, you can press the pedal
all the way down. While the speed
is being exceeded, the speed dis-
played in zone
A will fl ash. You have
only to release the accelerator pedal
to return below the maximum speed,
to restore the function.
The speed will also fl ash if the speed
limiter is not able to prevent the vehi-
cle from exceeding the programmed
speed (e.g. on a steep descent or
under excessive acceleration).
To reactivate the speed limiter, re-
lease the accelerator to slow to a
speed lower than the programmed
speed. Return to normal driving

 Either press on button 5 .

 Or select the speed limiter func-
tion.

 Or stop the engine.
