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
irst for further information.
Automatic adjustment
For vehicles with Xenon bulbs, this
system automatically corrects the
height of the beam, whatever the
load of the vehicle. 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 signiicantly
increased (approximately 12 mph
[20 km/h] more). Sequential control
of the gearbox may also become
unavailable. Lighting
Bicycle carrier If you it a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display’s
coniguration menu.
Refer to the "Identiication
features" section of chapter 9. 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 8.
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 itted 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 itting
should be carried out by a professional,
we recommend that you entrust the
itting 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 itting 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.

Snow screen
VERY COLD CLIMATE SCREEN
If itted 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.

LOW FUEL LEVELThe tank must be illed with fuel with
the engine off
.
- Open the fuel iller lap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to the
clip located on the inside of the lap.
FILLING THE FUEL TANK
When the fuel iller lap 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 reitted on
the tank.
FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine.
The lashing of this warning
light is accompanied by a
message on the display.
When the tank’s minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel
level low" on the display.
You have enough fuel left to cover
approximately 30 miles (50 km) ,
depending on driving conditions and
the engine.
If the warning light lashes, this
indicates a fuel gauge malfunction.
Consult a PEUGEOT dealer.
DIESEL REPRIMING PUMP
If you should run out of fuel, it is
necessary to re-prime the circuit:
- ill the fuel tank with at least ive 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.
A label on the inside of the lap
indicates which type of fuel to use.
If you ill your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
The capacity of the tank is
approximately 18 gallons (
80 litres).
- After illing the tank, lock the cap
and close the lap. Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:
F
switch off the ignition
(STOP position).
F remove the key.
F put the key back in the ignition.
F switch on the ignition and start.
