Malfunctions
Depending on the vehicle’s equipment:In the event of a system malfunction, this
warning lamp flashes on the instrument
panel.
The warning lamp in this button flashes and a message appears, accompanied by
an audible signal.
Have the vehicle checked by a PEUGEOT
dealer or a qualified workshop.

►

Switch off the ignition then start the engine
again with the key or the " ST

ART/STOP" button.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a PEUGEOT dealer or a
qualified workshop.
Under-inflation detection
This system automatically checks the tyre pressures while driving.
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.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
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-inflated 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 inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.

Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Selecting the mode
A confirmation message is displayed when
energy economy mode is entered, and the active
functions are placed on standby.
If a telephone call is in progress at the
time, it will be maintained for around 10
minutes via the audio system’s hands-free
system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
–

For less than 10 minutes, to use the
equipment for approximately 5 minutes.
–


For more than 10 minutes, to use the
equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
T

o recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from starting.
For more information on the 12
V battery,
refer to the corresponding section.

Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.

Preset radio stations.
The Stop & Start system may not be operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous period of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).Towing the vehicle
General recommendations
Observe the legislation in force in the country where you are driving.
Ensure that the weight of the towing vehicle is higher than that of the \
towed vehicle.
The driver must remain at the wheel of the towed vehicle and must have a\
valid driving licence.
When towing a vehicle with all four wheels on the ground, always use an \
approved towbar; ropes and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine off, there is no longer braking and steering assistance.
A professional recovery service must be called if:
– broken down on a motorway or main road;
– not possible to put the gearbox into neutral, unlock the steering, or re\
lease the parking brake;
– not possible to tow a vehicle with an automatic gearbox, with the engine\
running;
– towing with only two wheels on the ground;
– four-wheel drive vehicle;
– no approved towbar available.
