Driving
6If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are located as close as possible
to the axle, and the nose weight (at the point
where it joins your vehicle) approaches the
maximum permitted, without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine PEUGEOT towing device is
used, the rear parking sensors will be
deactivated automatically to avoid activating
the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►

Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system. It
activates automatically when the key is removed
from the ignition.
When the ignition switch is turned on, a dialogue
is set up between the key and the electronic
immobiliser.
This warning lamp goes off after the key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a PEUGEOT
dealer.
Carefully note the key number. In case of
loss, the intervention of a PEUGEOT
dealer will be faster and more efficient if you
provide this number and the confidential card.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even in your
pocket, may cause the doors to be unlocked
accidentally.
The simultaneous use of other high-frequency
devices (mobile phones, home alarms, etc.),
may temporarily disturb the operation of the
remote control.
Except for reinitialisation, the remote control
cannot operate while the key is in the ignition
switch, even when the ignition is off.
Driving with the doors locked could make
it more difficult for the emergency
services to enter the vehicle in an emergency.
As a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.

Driving
When purchasing a second-hand
vehicle:
–

check that you are in possession of the
confidential card,
–


have the keys memorised by a PEUGEOT

dealer, to be sure that the keys in your
possession are the only ones that allow the
vehicle to be started.
Confidential card

It is given to you upon delivery of your vehicle
with the duplicate key.
It contains the identification code required for
any intervention by a PEUGEOT dealer on the
electronic engine immobiliser system. This code
is hidden by a film, which is to be removed only
when necessary.
Keep your card in a safe place, never inside the
vehicle.
When undertaking a long trip or journey
however, it is advisable to take this card with you
along with your personal papers.
Starting-switching off the
engine
Ignition switch

STOP position: Anti-theft.
The ignition is off.
MAR position: ignition on.
Certain accessories can be used.
AV V position: starter.
The starter is operated.
Avoid attaching heavy objects to the key or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.
Starting/Switching off the
engine (Diesel)
Starting
► With the parking brake applied and the
gearbox in neutral, turn the key to the MAR
position.
► Wait until this warning lamp goes out,
then operate the starter (AV V position)
until the engine starts.
The period of illumination of the warning lamp
depends on the climatic conditions.
When the engine is hot, the warning lamp lights
up for a few moments; you can start the engine
immediately.
►

As soon as the engine starts, release the key
so it returns to the

MAR position.
Immobiliser warning lamp
If this warning lamp lights up, change
keys and have the faulty key checked by a
PEUGEOT dealer.
Switching off
► Immobilise the vehicle.
► Move the key back to the STOP position.
In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited to
low or minus temperatures.

Driving
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking brake
manually then ensure that the parking brake
indicator lamp is on. Hill start assist is deactivated in the following
situations:
–

when the clutch pedal is released,
–

when the parking brake is applied,
–

when the engine is switched off,
–

if the engine stalls.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
The under-inflation detection system
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) as well as 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.
Tyre pressures should be checked when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds). Otherwise, add 0.3 bar to
the pressures shown on the label.
For more information on Identification
markings, including the tyre pressure label,
refer to the corresponding section.
The tyre pressure measurement unit can be configured via the MODE button: in the
"Tyre pressure" menu, select "psi/bar/kPa".
For more information on Vehicle configuration
(MODE), refer to the corresponding section.

Driving
6This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may vibrate slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a system malfunction, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.
Audible rear parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever .

The proximity information is indicated by an
audible signal which becomes more rapid as the
vehicle approaches the obstacle.
When the distance between the rear of
the vehicle and the obstacle is less than
approximately 30 centimetres, the audible signal
becomes continuous.
Switching off
► Disengage reverse gear and shift to neutral.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel.
Consult a PEUGEOT dealer or a qualified
workshop.
