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.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by PEUGEOT
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings , refer to the
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160
km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if
necessary, to slow the vehicle (indicated by the
flashing of this warning lamp on the instrument
panel and the brake lamps coming on).
For more information on weights and towed
loads, refer to the Engine technical data
and towed loads section or your vehicle’s
registration certificate.
To ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a PEUGEOT dealer or a
qualified workshop.
The trailer stability control system provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g.
excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking. CarM an uals 2 .c o m

Driving
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►

Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
►


Drive smoothly
, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
►

Stop the vehicle before performing operations
that require sustained attention (e.g.

settings).
►

During long trips, take a break every 2 hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damaging the braking system!
Never park the vehicle and never
leave the engine running on a
flammable surface (e.g.
dry grass, dead
leaves).The vehicle exhaust system is very
hot, even several minutes after the engine
stops. Risk of fire!
Never drive on surfaces covered with
vegetation (e.g. tall grass,
accumulated dead leaves, crops, debris)
such as a field, a country lane overgrown
with bushes or a grassy verge.
This vegetation could come into contact with
the vehicle's exhaust system
or other systems
which are very hot. Risk of fire!
Make sure you do not leave any item in
the passenger compartment which could
act like a magnifying glass under the effect of
the sun's rays and cause a fire. Risk of fire or
damage to interior surfaces!
Never leave the vehicle unattended,
with the engine running . If you have to
leave your vehicle with the engine running,
apply the parking brake and put the gearbox
into neutral or position N or P (depending on
the type of gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the internal combustion engine or electric motor,
the gearbox and the electrical systems of the
vehicle.


If the vehicle absolutely must drive through a
flooded section of road:
►

Check that the depth of the water does not
exceed 15

cm, taking account of waves that
might be generated by other users.
►

Deactivate the Stop & Start function.
►


Drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10

km/h).
►

Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow

, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a PEUGEOT dealer or a qualified
workshop. CarM an uals 2 .c o m

Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If 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 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 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 a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a PEUGEOT dealer.
Starting/switching off the
engine
The electronic key must be present in the passenger compartment.
The electronic key is also detected in the
boot.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off. CarM an uals 2 .c o m

Gear shift indicator
(Depending on engine)
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
Operation
Depending on the driving situation and
the vehicle's equipment, the system may
recommend skipping one or more gears.
Gear engagement recommendations are
not to be considered mandatory. Indeed, the
configuration of the road, the traffic density and
safety remain determining factors when choosing
the best gear. Therefore, the driver remains
responsible for deciding whether or not to follow
the system’s advice.
The system cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g. slope, load) and driving style
(e.g. power demand, acceleration, braking).
The system never suggests:
–

engaging first gear
.
–

engaging reverse gear
.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
By default, the function is activated when the
ignition is switched on.
It is configured in the ADAS touch screen
application.

is turning left or right and detects a crossing
pedestrian if:
–
The pedestrian is crossing in front of the
vehicle.
–


The pedestrian can clearly be detected by the
sensors.
–


The scenery is detectable by the sensors (e.g.
brightness, contrast vs background).
–


The vehicle speed is between 3 and 15
mph
(5 and 25
km/h).
Malfunction
This warning lamp lights up on the instrument panel, if the automatic braking
system is reduced or degraded.
This is a normal behavior, which does not
request the support of a qualified workshop.
This may be caused by a reduced visibility
(e.g. rain, fog, snow, blinding by low sun) or by
a real sensor blockage. In this case, stop the
vehicle and verify if the front camera or the front
radar is covered by dirt, snow, ice or anything
preventing the sensing.
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.
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.
These warning lamps light up on the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's
and/or front passenger's seat belt is not fastened
(depending on version). The automatic braking
system is deactivated until the seat belts are
fastened.
Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The function comprises the "Driver Attention
Warning" system combined with the "Driver
Attention Warning by Camera" system.
These systems are in no way designed
to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated
at every engine start.
The settings are changed via the ADAS
touch screen application.
Driver Attention Warning
The system triggers an alert when it detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes. CarM an uals 2 .c o m
