AUTOMATIC SWITCHING ON
OF THE LIGHTS
Side lights and dipped beam head
lamps switch on automatically if the
light is poor, or during continuous
operation of the windscreen wipers.

To disarm or activate the function: Place the key in the accessories
position (1st notch),
 Press the end of the lights stalk
for more than two seconds.
Note: In foggy weather, the bright
ness sensor can detect sufficient

not come on automatically.
Do not cover the brightness sen
sor connected to the rain sensor,
located in the windscreen behind
the mirror. It is used for automatic
switching on of the lights. Operating check
Activation
Activation of this function is accom
panied by an audible signal and the
message
"Automatic lighting of
the headlamps activated" on the

the lights remain on.
It is however possible to disarm this
function and switch off the lights by:
manually switching off the lights using the lights stalk,
switching off the engine.

The ESPsystem offers
increased safety during
normal driving, but should
not incite the driver to take
risks or to drive at high speed.
The operation of the system is
assured to the extent to which the
recommendations of the manufac
turer regarding the wheels (tyres
and wheel rims), the braking com
ponents, the electronic compo
nents and the assembly and repair
procedures within the PEUGEOT
network are respected.
After an accident or impact, have
the system checked by a
PEUGEOT dealer.
DRIVING YOUR 406

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and com
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act
ing on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the tra
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle
back on course.
Operation of the ASR and ESP
systems
When one of these two sys
tems is operating, this light
flashes. Handbrake
Applying
When parking, pull the handbrake to
immobilise your vehicle.
W
arning: when parking on a slope,
direct your wheels towards the pave
ment and apply the handbrake.
Releasing
Pull the handle and press the button
to release the handbrake.
Disarming the ESP / ASR systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...),
it could prove useful to disarm the
ASR system to make the wheels
spin and regain grip. 
Press the switch "ESP OFF", sit
uated to the left of the steering
wheel.
The switch lights up and the indicator
lights come on, accompanied by the
message '' ASR/ESP deactivated''
on the multifunction display: the
ESP and ASR systems no longer
affect the operation of the engine or
the brakes.
They engage again: automatically when the ignition is
switched off,
 manually by pressing the switch
again.
Operating check When a system malfunction
occurs, the switch light
flashes and the indicator
light comes on.
Contact a PEUGEOT dealer to
check the system.

BATTERY
To charge the battery using a battery charger:
Disconnect the battery,
Follow the instructions for use given by the battery charger manufacturer,
Reconnect starting with the negative (–) terminal,
Check that the terminals and connectors are clean. If they are covered with sul
phate (white or greenish deposit), disconnect them and clean t hem.
To start the vehicle from another battery:
Connect the red cable to the positive (+) terminals of the tw o batteries,
Connect one end of the green or black cable to the negat ive (–) terminal of the
slave battery,
Connect the other end of the green or black cable to an e arth point on the bro
ken down vehicle, as far as possible from the battery,
Operate the starter, let the engine run.
Wait for the engine to return to idle, then disconnect th e cables.
Never disconnect a terminal when the engine is running.
Never charge a battery without first disconnecting the terminal s.
Close the sunroof before disconnecting the battery. If it does not
operate normally following reconnection of the battery, you must
reinitialise it by turning the control to the maximum tilt po sition and pressing
it for a few seconds.
After every reconnection of the battery, switch on the igniti on and wait
1 minute before starting to allow the electronic systems to be initialised. If
slight difficulties are experienced after this, please contact a PEUGEOT
dealer. It is advisable to disconnect the battery if the vehicle
is not to be used for a period of more than one month.Economy mode
With the engine switched off and the
ignition key in the "running" or
"accessories" position for about half
an hour, certain electrical equipment
(displays, instrument panel, warning
lights, courtesy lights, electric win

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow
bars that have been tested and
approved from the design stage of
your vehicle.
The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically designed for
transporting people and luggage but
it may also be used for towing a
trailer.
Driving with a trailer subjects the
towing vehicle to more significant
stress and its driver must be particu
larly careful.
Air density decreases with altitude,
thus reducing engine performance.
The maximum towing load must
be reduced by 10% for every
1000 metres of altitude.
Driving advice
Distribution of loads:
Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it. Cooling:
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.
On the contrary, use a high gear to
lower the engine speed, and reduce
your speed.
The maximum towing speed on a
long slope depends on the gradient
and the outside temperature.
For vehicles fitted with a direct injec
tion petrol engine, after towing or dri
ving at high speed for a long period
of time, the fan may operate for
approximately 6 minutes.
In all cases, pay attention to the
coolant temperature.
If the warning light comes on, stop
the vehicle and switch off the engine
as soon as possible.
Tyres:
Check the tyre pressures of the tow
ing vehicle and the trailer, observing
the recommended pressures.
Brakes:
Towing increases the braking distance.
Lights:
Check the electrical signalling on the
trailer.
Side wind:
Take into acount the increased sen
sitivity to side wind.
