Procedure for starting the engine using another
battery or charging a discharged battery.
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with
household waste.
Take used remote control batteries and
vehicle batteries to a special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards. Versions equipped with Stop & Start are
fitted with a 12
V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a PEUGEOT dealer or a qualified
workshop.

Starting using another
battery
When your vehicle's battery is flat, the engine
can be started using a backup battery (external
or from another vehicle) and jump leads or a
battery booster. Never try to start the engine by connecting
a battery charger.
Never use a 24
V or higher battery
b o o s t e r.
First check that the backup battery has
a nominal voltage of 12
V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact
with each other.
Switch off all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to moving parts of the engine (fan,
belts, etc.).

3 The different functions and settings
described vary according to the version
and configuration of your vehicle.
As a safety measure and because it
requires sustained attention by the
driver, the pairing of a Bluetooth mobile
telephone with the Bluetooth hands-free
system of your audio system must be
done with the vehicle stationary
and the
ignition on.
Your audio system is coded in such a way
that it will only operate in your vehicle.
All work on the system must be
carried out exclusively by a dealer or
qualified workshop, to avoid any risk of
electrocution, fire or mechanical faults.
To avoid discharging the battery, the audio
system may switch off after a few minutes
if the engine is not running.

QUESTIONRESPONSESOLUTION
With the engine off, the audio system switches
off after a few minutes of use. When the engine is switched off, the audio
system operating time depends on the state of
charge of the battery.
The switch-off is normal: the audio system
switches to economy mode and switches off to
prevent discharging the vehicle's battery.Start the vehicle’s engine to increase the
battery charge.
The message "the audio system is overheated"
appears on the display. In order to protect the installation if the
surrounding temperature is too high, the audio
system switches to an automatic thermal
protection mode leading to a reduction of the
volume.Switch the audio system off for a few minutes
to allow the system to cool.
Radio
QUESTION
RESPONSESOLUTION
There is a difference in sound quality between
the different audio sources (radio, USB, etc.). To allow for optimal listening quality, the audio
settings (Volume, Bass, Treble, Ambience,
Loudness) can be tailored to different
sound sources, which can generate audible
differences when changing source (radio, USB,
e t c .) .Check that the audio settings (Volume, Bass,
Treble, Ambience, Loudness) are adapted
to the sources listened to. It is advisable
to set the audio functions (Bass, Treble,
Front-Rear Fader, Left-Right Balance) to the
middle position, select the musical ambience
"None" and set the loudness correction to the
"Inactive" position in radio mode.
The preset stations do not function (no sound,
87.5
MHz is displayed, etc.). An incorrect waveband is selected.
Press the BAND button to return to the
waveband (FM, FM2, DAB, AM) on which the
stations are preset.
