These are located on the side of the
seat:
- Place the ignition key in the 'running' position (2nd notch),
- Adjust your seat,
- Press button M , then button 1 for
a fi rst driving position within four
seconds.
Repeat the same actions on buttons M
and 2 to store another driving position.
An audible signal confi rms that a
position has been memorised.
Memorising a new position cancels the
previous one.
Activating a memorised driving
position Front heated seat controls
When the engine is running, the front
seats can be heated separately.

IMPROVED SAFETY AND SECURITY
In the event of a front impact, the
retractable steering column limits the
backwards movement of the steering
wheel and the risks of intrusion of the
engine and gearbox into the passenger
compartment are reduced.
In the event of a side impact, you are
inside a cell armed with solid side
strengtheners.
With 5 stars in
the Euro NCAP
ADULT OCCUPANT
PROTECTION tests,
the 807 protects you
in several ways. Its
structure absorbs
a large proportion of the energy
connected with impacts.
Tests carried out on an 807 fi tted with
the 2.0 HDi engine.

Details of the other components are
given in the content of this chapter.

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
Activation of the ASR and ESP
systems
When the ignition is on, the ASR and
ESP systems are always active. Disarming the ASR/ESP systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...), it
could prove useful to disarm the ASR
and ESP systems to make the wheels
spin and regain grip.
- Press the switch, situated under the
steering wheel on the right of the
fascia.
The indicator light comes on
accompanied by a message:
the ESP and ASR systems
no longer act on the engine
operation, but continue to act
on the brakes. Operating check
The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the
driver to take risks or to drive at high
speed.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the fi tting and repair
procedures within the PEUGEOT
network are observed.
After an impact, have the system
checked by a PEUGEOT dealer.

They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the switch again.
Operation of the ASR and
ESP systems
The warning light fl ashes if
the ASR or ESP is activated.
These systems are linked and
complement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by acting
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
trajectory 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, within the limits of the laws
of physics.
When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Contact a PEUGEOT dealer to have
the system checked.

Towing a trailer
ACCESSORIES
5
TOWING A TRAILER, CARAVAN, BOAT, ETC...
Refer to the administrative
documents (V5, ...) or to the Petrol
or Diesel "Dimensions, weights
and towed loads" section of
chapter 8.
Distribution of loads: distribute the
load in the trailer so that the heaviest
loads are as close as possible to the
axle and the nose weight is close
to the maximum authorised without,
however, exceeding it.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.

Dimension A = 0.96 m
Driving advice
A towed vehicle must free wheel:
gearbox in neutral.

108
Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually. Please contact a PEUGEOT dealer
fi rst for further information .
Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signifi cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.
Lighting
Bicycle carrier
Refer to the "Identifi cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.

If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
PEUGEOT towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be fi tted in
accordance with the manufacturer’s
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this fi tting
should be carried out by a professional,
we recommend that you entrust the
fi tting of this equipment to a PEUGEOT
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with fi tting a towbar or other electrical
accessory which is not recommended
by the PEUGEOT network. Fitting such
equipment could result in a failure of
your vehicle’s electronic system. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display’s
confi guration menu.

110
Snow screen
VERY COLD CLIMATE SCREEN
If fi tted on your vehicle, this is a
removable part which permits complete
or partial covering of the front air intake
(grille, ...) to favour the increase in the
engine temperature when driving in
very low temperatures and to prevent
the entry of snow into the engine
compartment.
FITTING

 Offer up the screen facing its
centring pin A on the front bumper.

 Put it in place by pressing at each
clip B located in the four corners.
REMOVAL

 Pass a screwdriver into the hole
located near each of the clips.

 Use the screwdriver as a lever to
unclip the four clips B in turn.

When the snow has cleared, do not
forget to remove the very cold climate
screen.

Fuel
LOW FUEL LEVEL
Filling with fuel
The tank must be fi lled with fuel with

the engine off .
- Open the fuel fi ller fl ap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to the clip located on the inside of the
fl ap.
It is usual to hear an air intake noise
when opening the cap as there is a
vacuum linked with the sealing of the
fuel circuit.
A label on the inside of the fl ap
indicates which type of fuel to use.
More than 5 litres of fuel must be
added in order to be registered by the
fuel gauge.
If you fi ll your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
FILLING THE FUEL TANK
If the warning light fl ashes, this
indicates a fuel gauge malfunction.
Consult a PEUGEOT dealer.
When the tank’s minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel level
low" on the display. When
this warning light fi rst comes on, you
have approximately 8 litres left,
depending on driving conditions and
the engine.
Fill up with fuel as soon as possible to
avoid running out.
Never continue to drive until you run
out of fuel as this could damage the
emission control and injection systems. The capacity of the tank is
approximately 18 gallons (
80 litres).
- After fi lling the tank, lock the cap and close the fl ap. Quality of the fuel used for petrol
engines
The petrol engines are perfectly
compatible with E10 type petrol
biofuels (containing 10 % ethanol),
conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for
vehicles marketed for the use of this
type of fuel (BioFlex vehicles). The
quality of the ethanol must comply with
European standard EN 15376.
For Brazil only, special vehicles are
marketed to run on fuels containing up
to 100 % ethanol (type E100). When the fuel fi ller fl ap is open, a
system limits the opening of the
rear left sliding side door.
The key cannot be removed from the
cap’s lock until the cap is refi tted on
the tank.

FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine. The fl ashing of this warning
light is accompanied by a
message on the display.
DIESEL REPRIMING PUMP
If you should run out of fuel, it is
necessary to re-prime the circuit:
- fi ll the fuel tank with at least fi ve litres of diesel,
- squeeze and release the manual re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,
- operate the starter until the engine starts.
Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:
- switch off the ignition (STOP position).
- remove the key.
- put the key back in the ignition.
- switch on the ignition and start.
Quality of the fuel used for Diesel
engines
The Diesel engines are perfectly
compatible with biofuels which conform
to current and future European
standards (diesel fuel which complies
with standard EN 590 mixed with a
biofuel which complies with standard
EN 14214) available at the pumps
(containing up to 7 % Fatty Acid Methyl
Ester).
The B30 biofuel can be used in certain
Diesel engines; however, this use
is subject to strict application of the
special servicing conditions. Consult a
PEUGEOT dealer.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or
diluted, domestic fuel...) is strictly
prohibited (risk of damage to the
engine and fuel circuit).
