Driving
Never leave the vehicle without first
switching the ignition off with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not activated when:– the system is initialising,– the driver's door is open,– the driver's seat belt is not fastened,– the air conditioning is on,– the rear screen demisting is on,– the windscreen wipers are on fast wipe,– the reverse gear is engaged for the parking manoeuvre,– some special conditions (battery charge, engine temperature, particle filter regeneration,
braking assistance, exterior temperature, etc.)
where the engine is needed to assure control of
a system.
– during intensive use of Stop & Start, it may be deactivated to conserve starting ability; go
to a PEUGEOT dealer to have the function
reactivated.
This indicator lamp in the instrument panel flashes for a few seconds, then
goes off.
This operation is perfectly normal.
Going into engine START
mode
With a gear engaged, the automatic restarting of the engine is only possible by fully depressing the clutch pedal.This indicator lamp goes off and the engine restarts.
If, after an automatic restart in START mode, the
driver does not perform any action on the vehicle
within 3 minutes, the system stops the engine
permanently. The engine can only be restarted
with the ignition key.
Special cases: START mode
activated automatically
The START mode may be invoked automatically
in the following circumstances:
– the vehicle is free-wheeling on a gradient,– the windscreen wipers are on fast wipe,– the air conditioning is on,– the engine has been stopped for around 3 minutes with Stop & Start,
– some special conditions (battery charge, engine temperature, braking assistance, air
conditioning setting, etc.) where the engine is
needed for control of the system or vehicle.
In this case, a message appears in the
instrument panel screen, accompanied by
this indicator lamp, which flashes for a few
seconds, then goes off.
This operation is perfectly normal.
While in STOP mode with a manual
gearbox, if a gear is engaged without
fully depressing the clutch pedal, restarting
may not take place.
An indicator lamp and/or message is
displayed in the instrument panel asking
you to fully depress the clutch pedal to allow
restarting.
With the engine stopped in STOP mode,
if the driver unfastens their seat belt and
opens a front door, the engine can only be
restarted using the ignition key. There is an
audible signal, accompanied by flashing of this
indicator lamp, and the display of a message.
Malfunction
In the event of a malfunction, the Stop &
Start is deactivated and this warning lamp
comes on, accompanied by a message on the
instrument panel display.
Have the system checked by a PEUGEOT
dealer or a qualified workshop.
In the event of a malfunction in STOP mode, the
engine can be restarted by fully depressing the clutch pedal or putting the gear lever in neutral.
Hill start assist
This system keeps your 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.
This system (also called HHC - Hill Hold Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running, foot on the brake,– the gradient of the road must be steeper than 5%,– uphill, the gearbox must be in neutral or in a gear other than reverse,– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,

6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running, foot on the brake,– the gradient of the road must be steeper than 5%,– uphill, the gearbox must be in neutral or in a gear other than reverse,– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
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
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system 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 fuel consumption.

Driving
– Auto: for an automatic detection of the trailer
length (3 m, 6 m or 9 m).
In Auto mode, an icon appears in the instrument
panel indicating the length detected by the
system.
It may be necessary to make a 90° turn
to allow the system to detect the length
of the trailer.
When a trailer is detected, vehicle detection
when reversing is deactivated.
Operating conditions
– All vehicles are moving in the same direction and in adjacent lanes.– The speed of your vehicle is 6 mph (10 km/h) minimum. – When you overtake a vehicle, the speed difference is less than 16 mph (25 km/h).– When another vehicle overtakes you, the speed difference is less than 31 mph (50 km/h).
Active Safety Brake with Distance Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:– warns the driver that their vehicle is at risk of collision with the vehicle in front.– reduces the vehicle's speed to avoid a collision or limit its severity.
This system is comprised of three functions:
– Distance Alert.
– Intelligent emergency braking assistance.– Active Safety Brake (automatic emergency braking).

The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
This function can be set using the MODE
button; select “ON” or “OFF” in the “Active
Safety Brake” menu.
For more information on Vehicle
configuration (MODE) , please refer to
the corresponding section.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system via the vehicle's configuration menu is advised:– towing a trailer,– carrying long objects on roof bars or roof rack,– with snow chains fitted,– before using an automatic car wash, with the engine running,– before placing the vehicle on a rolling road in a workshop,– towed vehicle, engine running,– following an impact to the windscreen close to the detection camera.
It is automatically deactivated after
detection of a fault with the brake pedal
switch or with at least two brake lamps.
After an impact, the function automatically stops operating. Contact a
PEUGEOT dealer or a qualified workshop to
have the system checked.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the road.– Vehicles crossing your lane.– Vehicles driving in the opposite direction.

The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the road.– Vehicles crossing your lane.– Vehicles driving in the opposite direction.

Pay particular attention:– When narrow vehicles (motorcycles) are present and/or there are vehicles
staggered across the traffic lane.
– When entering a tunnel or crossing a bridge.
When the driver must suspend the system:


– Vehicles in a tight bend.– When approaching a roundabout.

– When a vehicle cuts in sharply between your vehicle and the one in front.
Distance Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the vehicle configuration menu.
► Select one of the three pre-defined thresholds:– "Near ".– "Normal".– "Distant".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange): visual alert only,
signalling that the vehicle in front is very
close.

86
Driving
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
signalling that a collision is imminent.
The message "Brake! " is displayed.
Level 3: finally, in some cases, a haptic alert
in the form of micro-braking can be given,
confirming the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important:
the level 1 alert is never displayed for a stationary obstacle or when the " Close"
trigger threshold has been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and 53 mph (5 km/h and 85 km/h) when a moving vehicle is detected.
This warning lamp flashes (for about 10 seconds) once the function is acting on the vehicle's brakes.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
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
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 capacity of the tank is about 90 litres.
Fuel tanks of different capacities may be fitted,
60 and 120 litres, depending on the engine.
Low fuel level
When the low fuel tank level E (Empty) is
reached, this warning lamp comes on.
At this moment, you have approximately 10 or
12 litres left in the reserve, depending on the
capacity of your tank and the engine.
You must refuel as soon as possible to avoid
running out of fuel.
Refuelling
The fuel tank must be filled with the engine off.► Open the fuel filler flap.► Hold the black filler cap with one hand.► With the other hand, insert the key and turn it anti-clockwise.

► Remove the black filler cap and hang it on the hook located on the inside of the filler flap.
A label inside the fuel filler flap indicates the type
of fuel to use.
Do not continue past the 3

Diesel at low temperature
At temperatures below 0 °C (+32 °F), the formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.At temperatures below -15 °C (+5 °F) to avoid problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the
vehicle when braking.
The snow chains must be fitted only to the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Observe the legislation in force in your
country on the use of snow chains and
the maximum authorised speed.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original tyre size Maximum link size.
205/70 R15 16 mm
215/70 R15 12 mm
225/70 R15 16 mm
215/75 R16 12 mm
225/75 R16 16 mm
For more information on snow chains, contact a
PEUGEOT dealer or a qualified workshop.
Installation tips
► To fit the chains during a journey, stop the vehicle on a flat surface on the side of the road.► Apply the parking brake and position any wheel chocks under the wheels to prevent
movement of the vehicle.
► Fit the chains following the instructions provided by the manufacturer.► Move off gently and drive for a few moments, without exceeding 31 mph (50 km/h).► Stop the vehicle and check that the snow chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
