Safety
5Passengers must not place their feet on the 
dashboard.
Do not smoke as deployment of the airbags 
can cause burns or the risk of injury from a 
cigarette or pipe.
Never remove or pierce the steering wheel or 
hit it violently.
Do not fix or attach anything to the steering 
wheel or dashboard, as this could cause 
injuries when the airbags are deployed.
Lateral airbags
Use only approved seat covers 
compatible with the deployment of these 
airbags. For information on the range of seat 
covers suitable for your vehicle, contact a 
PEUGEOT dealer.
Do not fix or attach anything to the seat 
backrests (e.g.
  clothing) as this could cause 
injuries to the chest or arm when the airbag is 
deployed.
Do not sit with the upper part of the body any 
nearer to the door than necessary.
The vehicle's front door panels include side 
impact sensors.
A damaged door or any unauthorised or 
incorrectly executed work (modification or 
repair) on the front doors or their interior trim 
could compromise the operation of these 
sensors - risk of malfunction of the lateral 
airbags!
All work must be carried out only by a 
PEUGEOT dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof, 
as this could cause head injuries when the 
curtain airbag is deployed.
Do not remove the grab handles installed on 
the roof, as these help to secure the curtain 
airbags.
Active bonnet 
 
The active bonnet has been designed to 
optimise the safety of pedestrians in the event of 
collision with the front of the vehicle.
The pyrotechnic system is triggered at the 
hinges of the bonnet to lift it, when the sensors 
located at the front of the vehicle detect a 
collision.
Deployment of the active bonnet is 
accompanied by a slight discharge of 
harmless smoke and a noise, due to the 
activation of the pyrotechnic cartridge 
incorporated in the system. The airbag 
warning lamp comes on.
After triggering, do not try to open or close 
the bonnet. Call a towing company or go to 
the nearest PEUGEOT dealer or qualified 
workshop, driving at a speed below 19 mph 
(30
  km/h).
Make sure that you adjust the height of the 
driver's seat - risk of hindrance to visibility!
This equipment will only trigger once. If a  second impact occurs (during the same 
or a subsequent accident), the active bonnet 
will not trigger.
After an accident or if the vehicle has been 
stolen, have the system checked.
Do not tamper with the pyrotechnic systems 
under the bonnet, close to the struts - risk of 
explosion!
All work must be carried out only by a 
PEUGEOT dealer or a qualified workshop
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. You must contact a PEUGEOT 
dealer or a qualified workshop to have the 
system checked.
The active bonnet may not deploy in the event of 
an impact.

Driving
► 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.
Towing
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.

Active Suspension Control
This system adapts the vehicle suspension 
according to the road condition and profile, the 
vehicle load, the driving style and the selected 
driving mode.
The system uses a computer and sensors, which 
determine the optimal level of shock absorption 
to be applied to each shock absorber.
The operation of the system depends on 
the driving mode selected
  (depending on 
equipment).
For more information on the  Driving modes, 
please refer to the corresponding section.
Malfunction
In the event of a malfunction, this warning 
lamp lights up on the instrument panel.

– The outside temperature must be between 
0°C and 35°C.
Putting the engine into standby 
(STOP mode)
The engine automatically enters standby mode 
as soon as the driver indicates their intention to 
stop:
–
 
At speeds below 12 mph (20
   km/h) on 
BlueHDi versions, or below 0.6 mph (1
  km/h) on 
PureTech versions, when you brake firmly with 
the gear selector in mode  D.
–
 
With the vehicle stationary
 , when you select 
the mode N with the gear selector.
Time counter
A time counter adds up the time spent in standby 
during the journey. It is reset to zero every time 
the ignition is switched on.
Special cases
The engine will not go into standby if the 
conditions for operation are not met and in the 
following cases:
–
 
Steep slope (ascending or descending).
–
 
Sport mode selected (depending on 
equipment).
–
 
Needed 
 to maintain a comfortable temperature 
in the passenger compartment.
–
 
Demisting active.
In these cases, this indicator lamp flashes 
for a few seconds, then goes off.
After the engine has restarted, STOP mode is not available until the vehicle 
has reached a speed of 5 mph (8
  km/h).
During parking manoeuvres, STOP mode 
is not available for a few seconds after 
coming out of reverse gear or turning the 
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the 
driver indicates the intention of moving off again:
–

exceeds 0.6 mph (1 km/h).
In this case, this indicator lamp flashes for 
a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this 
warning lamp flashes for a few moments 
on the instrument panel, then remains on, 
accompanied by the display of a message.
Have it checked by a PEUGEOT dealer or a 
qualified workshop.

12 V battery
The Stop & Start system requires a 
12 V battery of specific technology and 
specification.
All work must be carried out only by a 
PEUGEOT
 dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver if one or more tyres 
suffer a drop in pressure.
The alert is raised when the vehicle is moving, 
not when stationary.
It compares the information given by the wheel 
speed sensors with  reference values, which 
must be reinitialised every time the tyre 
pressures are adjusted or a wheel changed.   
Page 113 of 244
111
Driving
6It takes into account the last values stored 
during the reinitialisation request. It is therefore 
essential that the tyre pressure is correct during 
the operation. This operation is the driver’s 
responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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), especially 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.
For more information on the  Identification 
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly 
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.
Snow chains
The system does not have to be 
reinitialised after fitting or removing snow 
chains.
Under-inflation alert
This is signalled by the fixed illumination  of this warning lamp, accompanied by an 
audible signal and, depending on equipment, the 
display of a message.
►
 
Reduce speed immediately
 , avoid excessive 
steering movements and avoid sudden braking.
►
 
Stop the vehicle as soon as it is safe to do 
so.
The loss of pressure detected may not  always cause visible deformation of the 
tyre.
Do not rely on just a visual check.
►
 
Using a compressor
 , such as the one in 
the temporary puncture repair kit, check the 
pressures of all four tyres when cold.
►
 
If it is not possible to carry out this check 
immediately
, drive carefully at reduced speed.
►
 
In the event of a puncture, use the 
temporary puncture repair kit or the spare wheel 
(depending on equipment).
Driving too slowly may not ensure 
optimum monitoring.
The alert is not immediately triggered in the 
event of a sudden loss of pressure or tyre 
blow-out. This is because analysis of the 
values read by the wheel's speed sensors 
can take several minutes.
The alert may be delayed at speeds below 
25
 
mph (40   km/h), or when adopting a sporty 
driving mode.
The alert is kept active until the system is  reinitialised.
Reinitialisation
► The system must be reinitialised after any 
adjustment to the pressure of one or more tyres, 
and after changing one or more wheels.
Before reinitialising the system, make 
sure that the pressures of the four tyres 
are correct for the conditions of use of the 
vehicle and conform to the values written on 
the tyre pressure label.
Check the pressures of the four tyres before 
performing the reinitialisation.
The system does not advise if a pressure is 
incorrect at the time of reinitialisation.
With the vehicle stationary, the system 
can be   reinitialised   in the 
Settings>Vehicle touch screen application.
►
 
Then select 
 Safety   > Tire Pressure Setup.

Driving
6In the event of a windscreen replacement, 
contact a PEUGEOT dealer or a qualified 
workshop to recalibrate the camera; 
otherwise, the operation of the associated 
driving aids may be disrupted.
Other cameras
The images from the camera(s) 
displayed on the touch screen or on the 
instrument panel may be distorted by the 
terrain.
In the presence of areas in shade, or in 
conditions of bright sunlight or inadequate 
lighting, the image may be darkened and with 
lower contrast.
Obstacles may appear further away than they 
actually are.
Sensors
The operation of the sensors, as well as 
any associated functions, may be disrupted 
by noise pollution such as that emitted by 
noisy vehicles and machinery (e.g. lorries, 
pneumatic drills), by the accumulation of 
snow or dead leaves on the road or in the 
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible 
signal (long beep) indicates that the sensors 
may be dirty.
A front or rear impact to the vehicle can 
upset the sensors’ settings, which is not 
always detected by the system: distance 
measurements may be distorted.
The sensors do not systematically detect 
obstacles that are too low (pavements, studs) 
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind 
spots may not be detected or may no longer 
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound 
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and 
the field of vision of the cameras regularly.
When washing your vehicle at high pressure, 
direct the spray from at least 30
  cm away 
from the radar, sensors and cameras.
Mats/Pedal trims
The use of mats or pedal trims not 
approved by PEUGEOT may interfere with 
the operation of the speed limiter or cruise 
control.
To avoid any risk of jamming the pedals:
–
 
Ensure that the mat is secured correctly
 .
–
 
Never fit one mat on top of another
 .
Units of speed
Ensure that the units of speed displayed 
on the instrument panel (mph or km/h) are 
those for the country you are driving in.
If this is not the case, when the vehicle is 
stationary, set the display to the required 
units of speed so that it complies with what is 
authorised locally.
In case of doubt, contact a PEUGEOT dealer 
or a qualified workshop.
Shortcuts for driving aids
The full list of available driving aids can be found 
in the Functions  tab.
Driving aids can be accessed directly to quickly 
activate/deactivate them.
By default, driving aids are already stored in the 
Shortcuts tab (e.g.
  Stop & Start, Lane keeping 
assist).
Other driving aids can be added or deleted from 
this tab.
It is configured in the ADAS>Functions 
touch screen application.
► Press the button corresponding to the 
driving assistance concerned: 
•
 
Full symbol: the function is added to the 
Shortcuts
 tab.
•
 
Empty symbol: the function is deleted from 
the 
Shortcuts tab.

Speed limit at 
certain times of the  day
Example:
 
 
19 mph (30 km/h) 
(for example)
with a "clock" symbol
To get valid speed limit information, the  vehicle's current position is sent via the 
telematics unit and is immediately deleted 
after processing.
Tracking of the vehicle position is not possible 
at any time.
This is not impacted by the privacy settings of 
the connected services.
On-board navigation mapping should be 
regularly updated in order to receive 
accurate speed limit information from the 
system.
The units for the speed limit (mph or  km/h) depend on the country you are 
driving in.
This should be taken into account to ensure 
you observe the speed limit.
For the system to work properly when 
changing countries, the speed unit of the 
instrument panel must match that of the 
country you are driving in.
Country selection is only available for audio 
systems without on-board navigation.
Automatic sign reading is a driving aid  system and does not always display the 
correct speed limits.
The speed limit signs present on the road 
always take priority over those displayed by 
the system.

The country selection is saved when the 
ignition is switched off.
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.
This warning lamp lights up on the  instrument panel with the message 
"Driving Assistance Sensor blind: Clean 
sensor, see User Manual" if the sensor is 
masked.
This is a normal behavior, which does not 
request the support of a qualified workshop.
In this case, stop the vehicle and verify if the 
front camera is covered by dirt, mud, sand, 
snow, ice or anything preventing the sensing.
The system is operational again after the 
detection field has been cleaned.
Recommendation 
 
In addition to Road signs recognition , the 
driver can select the speed displayed as a speed 
setting for the speed limiter or cruise control 
using the speed limiter or cruise control 'store' 
button.
If rain is detected, the system will suggest to 
the driver a speed setting lower than the speed 
read/obtained from the mapping system in order 
to best suit the weather conditions (e.g. on a 
motorway, the suggested speed will be 68 mph 
(110 km/h) instead of 81 mph (130
  km/h)).
For more information on the Speed 
limiter, Cruise control or Adaptive 
cruise control, refer to the corresponding 
sections.

to save it as a new speed setting.
If there is a difference of less than 6 mph 
(9   km/h) between the speed setting and 
the speed displayed by the Road signs 
recognition, the " MEM" symbol is not 
displayed.
Depending on the road conditions, several 
speeds may be displayed.
