6Automatic gearbox
Never try to start the engine by pushing 
the vehicle.
Switching the vehicle off
Regardless of the current gearbox mode, mode 
P is immediately engaged automatically when 
the ignition is switched off.
However, in mode N, mode P will be engaged 
after a delay of 5
  seconds (time to enable free-
wheeling mode).
Check that mode
  P has been engaged and 
that the electric parking brake was applied 
automatically; if not, apply it manually.
The corresponding indicator lamps on the  gear selector and the electric parking 
brake control must be on, as well as the indicator 
lamps on the instrument panel.
Gearbox malfunction
This warning lamp comes on,  accompanied by an audible signal and 
the display of a message.
Go to a PEUGEOT dealer or a qualified 
workshop.
Do not drive faster than 62
  mph (100   km/h), 
keeping to the speed limit.
Switching of the gearbox to back-up mode
Mode D locks in third gear.
The paddles on the steering wheel do not work 
and mode  M is no longer accessible.
You may feel a significant jolt on engaging 
reverse gear. This will not damage the gearbox.
Selector malfunction
Minor malfunction
This warning lamp comes on, 
accompanied by the display of a message 
and an audible signal.
Drive carefully.
Go to a PEUGEOT dealer or a qualified 
workshop.
In some cases, the selector indicator lamps may 
no longer come on, but the gearbox state is still 
displayed on the instrument panel.
Major malfunction
This warning lamp comes on,  accompanied by the display of a 
message.
You must stop the vehicle.
Stop as soon as it is safe to do so and 
switch off the ignition.
Contact a PEUGEOT dealer or a qualified 
workshop.
Driving modes
The driving modes available depend on the  engine and equipment of the vehicle.
Driving modes are selected using the following 
control:
 
 
 
 
► Press the control to display the modes on the 
instrument panel.
►
 
Press the control again to change mode.
When the message disappears, the selected 
mode is activated and remains indicated on the 
instrument panel (except  Normal
  mode).
With petrol engines
Whenever the ignition is switched on,  Normal 
driving mode is selected by default.
Normal
To restore the default settings.
Eco
To reduce energy consumption by reducing the 
performance of the heating and air conditioning, 
without deactivating them.
Sport

the vehicle’s dynamic settings on the instrument 
panel (depending on version) and activation/
deactivation of the display colour (depending on 
version).
The selection of the Sport mode deactivates the 
Stop & Start function.
Coasting mode
Depending on version and engine, with 
the gear selector in mode  D, in
  Eco and 
Normal modes, gradually and fully releasing 
the accelerator pedal allows free-wheeling 
which can save fuel.
A drop in engine speed is normal (rev counter 
at idle, drop in engine noise).
With Rechargeable hybrid 
engines
Whenever the ignition is switched on,  Electric 
driving mode is selected by default.
Electric
Allows driving using 100% electrical energy. 
The maximum speed is approximately 84   mph 
(135
  km/h).
When starting the vehicle, if the conditions do 
not allow the activation or retention of  Electric 
mode, the message "Electric mode currently 
unavailable" is displayed on the instrument 
panel. The vehicle automatically changes to 
Hybrid mode.
Conditions of activation
– Adequate battery charge level. Charging 
the vehicle after each drive is therefore 
recommended.  Electric
 mode is available as 
long as there is power left in the battery.
–
 
Outside temperature between approximately 
-5°C and 45°C. 
Manually exiting the mode
►
 
Fully depress the accelerator pedal, or
►
 
Select another mode.
In case of non-use of the vehicle for a 
long period (several months), a restart of 
the petrol engine may occur even if the 
battery is charged.
In the event of multiple starts of the 
internal combustion engine without a 
sufficient rise in temperature,  Electric mode 
may be temporarily unavailable (natural 
phenomenon of dilution of fuel in oil). The 
message "Electric mode unavailable: 
automatic operation in progress " then 
appears on the instrument panel.
To regain normal electrical operation, drive 
approximately 50
  miles (80   km) in "motorway" 
conditions or approximately 125
  miles 
(200
  km) in urban conditions.
This phenomenon does not cause any 
mechanical or electrical damage. It can occur 
several times in the life of the vehicle.
Hybrid
To optimise the vehicle's fuel consumption by 
managing the  alternating or simultaneous 
operation of the two types of engine , 
depending on driving conditions and driving 
style.
In Hybrid mode, it is possible to drive in 100% 
electric mode if the battery charge level is 
sufficient and acceleration requirements are 
moderate.
Sport
To obtain more dynamic driving in order to 
benefit from the maximum performance of the 
vehicle.
Electric power is used to supplement the petrol 
engine as long as there is energy left in the 
battery.
Hill start assist
This system keeps the vehicle briefly stationary 
(for approximately 2   seconds) when making a hill 
start, while you transfer your foot from the brake 
pedal to the accelerator pedal.
The system is only active when:
–
 
The vehicle is completely stationary
 , with your 
foot on the brake pedal.
–
 
Certain slope conditions are met.
–
 
The driver
 ’s door is closed.  CarM an uals 2 .c o m

Driving
6Do not leave the vehicle while it is being 
held temporarily by hill start assist.
If someone needs to get out of the vehicle 
with the engine running, apply the parking 
brake manually. Then check that the parking 
brake indicator lamp and the  P indicator lamp 
in the electric parking brake control are on 
fixed.
The hill start assist function cannot be  deactivated. However, using the parking 
brake to immobilise the vehicle interrupts its 
operation.
Operation 
 
Facing uphill, with the vehicle stationary, 
the vehicle is held for a short time when the 
driver releases the brake pedal:
–
 
If mode 
 D or M is selected on an automatic 
gearbox.
 
 
Facing downhill, with the vehicle stationary 
and reverse gear engaged, the vehicle is held 
for a short time when the driver releases the 
brake pedal.
Malfunction
If the event of a malfunction, these 
warning lamps light up on the 
instrument panel, accompanied by the display of 
a message.
Have it checked by a PEUGEOT dealer or a 
qualified workshop.
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.  CarM an uals 2 .c o m

–
 
With the gear selector in mode  D
 or M, with 
the brake pedal depressed until the vehicle 
stops.
–
 
With the gear selector in mode  N
, with the 
vehicle stationary.
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)

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.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come 
on if there is a fault.
►
 
Switch off the ignition then start the engine 
again with the key or the " ST
ART/STOP" button.
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.
It 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   CarM an uals 2 .c o m

Driving
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.
►
 
Press 
 YES to confirm.
The
 
reinitialisation   is confirmed by the display of 
a message and an audible signal.
Malfunction
In the event of a malfunction, 
these warning lamps light up on 
the instrument panel.
A message appears, accompanied by an audible 
signal.
In this case, the tyre under-inflation monitoring 
function is no longer performed.
Have it checked by a PEUGEOT dealer or a 
qualified workshop.
Non-standard or 'space-saver' spare 
wheel
The use of this type of spare wheel may 
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp 
comes on and disappears once the wheel 
has been replaced by one of uniform size (the 
same as the others), the pressure readjusted 
and the
  reinitialisation   carried out.
Driving and manoeuvring 
aids - General 
recommendations
Driving and manoeuvring aids cannot, in 
any circumstances, replace the need for 
vigilance on the part of the driver.
The driver must comply with the Highway 
Code, must remain in control of the vehicle in 
all circumstances and must be able to retake 
control of it at all times. The driver must adapt 
the speed to climatic conditions, traffic and 
the state of the road.
It is the driver's responsibility to constantly 
monitor traffic conditions, assess the distance 
and relative speed of other vehicles, and 
anticipate their manoeuvres before using the 
direction indicator and changing lanes.
These systems do not make it possible to 
exceed the laws of physics.  CarM an uals 2 .c o m

105
Driving
6Driving aids
You should hold the steering wheel with 
both hands, always use the door and interior 
mirrors, always leave your feet close to the 
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the 
surroundings of the vehicle before and during 
the whole manoeuvre, in particular using the 
mirrors.
Radar(s)
The operation of the radar(s), along with 
any associated functions, may be affected 
by the accumulation of dirt (e.g.
  mud, ice), 
in poor weather conditions (e.g.
  heavy rain, 
snow), by the masking of the detection zone 
with adhesive labels or other objects, or if the 
bumpers are damaged.
If the front or rear bumper is to be repainted, 
contact a PEUGEOT dealer or a qualified 
workshop; certain types of paint could 
interfere with the operation of the radar(s).
Take care not to cover the detection zones 
on the front and rear bumpers with adhesive 
labels or other objects; they may hamper 
correct operation of the associated system.
 
 
Driving aids camera
This camera and its associated functions 
may be impaired or not work if the windscreen 
area in front of the camera is dirty, misty, 
frosty, covered with snow, damaged or 
masked by a sticker.
In humid and cold weather, demist the 
windscreen regularly.
Poor visibility (e.g.
  inadequate street lighting, 
heavy rain, thick fog, snowfall), dazzle 
(e.g.
  headlamps of an oncoming vehicle, low 
sun, reflections on a damp road, leaving a 
tunnel, alternating shade and light) can also 
impair detection performance.
In 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.  CarM an uals 2 .c o m  
Page 108 of 244

106
Driving
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.
Steering wheel with 
hands-on detection
(with Drive Assist 2.0)
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
The steering wheel is equipped with a hands-on 
detection system to avoid distraction on the part 
of the driver.
It is prohibited to cover or attach anything to the 
steering wheel.
The driver must always check the  surroundings of the vehicle and 
supervise the whole manoeuvre.
Any use of a system built into
  Drive Assist 
2.0
 
must remain under the driver’s vigilance.
The system also detects the presence of 
hands when using the Lane Positioning assist 
system with Drive Assist Plus.
The system may suffer interference or  not work correctly if:
–
 
the steering wheel is covered by some 
protection.
–
 
the driver wears thick gloves (e.g.
   ski 
gloves).
In the event of improper detection of hands 
on the steering wheel, Drive Assist 2.0 is 
not activated or is deactivated after a few 
seconds.
Installation of mechanical anti-theft 
devices on the steering wheel is 
prohibited - risk of damage!

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.
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 system is designed to detect signs that 
conform to the Vienna Convention on road 
signs.
Specific speed limits, such as those for 
heavy goods vehicles, are not displayed.
The display of the speed limit on the 
instrument panel is updated when passing 
a speed limit sign intended for cars (light 
vehicles).
Activation/Deactivation
By default, the system is automatically activated 
at every engine start.
