Gear shift indicator*System which reduces fuel consumption by advising the driver to change gear on vehicles fitted with a manual gearbox.
Operation
* Depending on engine.-
f
or a change up,
In the case of driving which makes
particular demands on the per formance
of the engine (firm pressure on the
accelerator pedal, for example, when
overtaking...), the system will not
recommend a gear change.
The system never suggests engaging
reverse gear.
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
intermediate gears.
The gear recommendations should not
be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining 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. A symbol appears in the instrument panel
when the system suggests changing to a more
suitable gear:

Stop & Start (auto Stop & Go) function
Operation
Going into engine STOP mode
The "AS &G" warning lamp comes on in
the instrument panel or the instrument
panel screen and the engine goes into
standby after a few seconds:
-

w

ith a manual gearbox , with the vehicle
stationary and your foot on the brake, when
you put the gear lever into neutral and
release the clutch pedal.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the START/STOP
button. When the engine is stopped
automatically, the operation of certain
vehicle systems, such as for example,
braking, power steering... are modified.
Ta k e c a r e.
Special cases: STOP mode not
available
STOP mode is not invoked when:
-
t he driver's seat belt is not fastened,
-

t
he driver's door is open,
-

t
he bonnet is open,
-

t
he minimum time period of 30 seconds
since starting the engine has not elapsed,
-

t
he vehicle has not exceeded 3 mph
(5
km/h) since the last engine start,
-

t
he vehicle has restarted less than
10
seconds ago,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
-

t
he "AS &G" warning lamp is
flashing in the instrument panel.
This operation is perfectly normal.
The Stop & Start (Auto Stop & Go) function puts the engine temporarily into standby during stops in the traffic (red lights, traffic jams, or other...).
The

engine restarts automatically as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start (Auto Stop & Go) function reduces fuel consumption and exhaust emissions as well as the noise level when
stationary.
If you move the gear lever, the "AS &G"
warning lamp flashes, accompanied by
an audible signal.
The alert stops as soon as the gear
lever is returned to the neutral position.

The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
Under-inflation detection
System which continuously and automatically checks the pressures of the four tyres after switching on the ignition.
A pressure sensor is located in the valve of each tyre (except the spare wheel).
The system triggers an alert if a drop in pressure is detected in one or more tyres, compared to the reference pressure registered in the system.
This reference pressure must be reinitialised every time the tyre pressures are adjusted or a wheel changed.
The system operates on condition that sensor identifiers have first been memorised in the system by a CITROËN dealer or a qualified workshop.
You can memorise two sets of tyres (for example: wheels with "standard" tyres and wheels with "winter" tyres).
Driving with under-inflated tyres
increases fuel consumption.This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.
