Driving
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving o󰀨 again:
– With the selector in mode D or M: with the
brake pedal released.
– With the selector in mode N and the brake
pedal released: when you place the gear
selector in mode D or M.
– With the selector in mode P and the brake
pedal depressed: when you place the gear
selector in mode R, N, D or M.
– With reverse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following case:
– Automatic gearbox in mode N, vehicle speed
exceeds 0.6 mph (1 km/h).
In this case, this indicator lamp ashes for
a few seconds, then goes o󰀨.
Malfunctions
In the event of a fault with the system, this
warning lamp ashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualied workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
► Switch o󰀨 the ignition then start the engine
again with the "START/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specic technology and
specication.
All work must be carried out only by a
CITROËN dealer or a qualied workshop
Tyre under-ination
detection
This system alerts the driver when one or more
tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes the last values stored during
the reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
The tyre under-ination detection cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding.
– lengthens braking distances.
– causes premature wear of the tyres.
– increases energy consumption.
The ination pressures dened for the
vehicle can be found on the tyre pressure
label.
For more information on the Identication
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10 km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
