Driving
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 climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two 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
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front 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.


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.
On versions with camera alone, this message
indicates to you that the camera is obstructed:
"Driving aids camera: visibility limited, see
user guide".
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(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
relief.
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
the associated functions may be disturbed
by sound interference 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
The use of mats 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.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
–

Speed limit signs detected by the camera.
–


Speed limit details from the navigation system

The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
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.
Refuelling
Fuel tank capacity: approximately 62 litres
(petrol), 55 litres (Diesel) or 42 litres (Hybrid).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal. When it first comes on,
about 6 litres of fuel remain in the tank.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by an onscreen message and
an audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Additions of fuel must be of at least 10 litres, in
order to be registered by the fuel gauge.
Opening the filler flap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
►
You must switch off the engine.

152
Practical information

► With the vehicle unlocked, press the rear
edge of the filler flap to open it (the filler cap is
built in).
►

T
ake care to select the pump that delivers the
correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
►

Introduce the filler nozzle and push it in as
far as possible before starting to refuel (risk of
blowback).
►


Fill the tank.
Do not continue past the 3rd cut-off of the
nozzle; as this may cause malfunctions.
►

Push the filler flap to close it.
The vehicle is fitted with a catalytic converter

, a
device which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be introduced.
If you have put in the wrong fuel for
the vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device appears when the filler cap is removed.
Operation

When a petrol filler nozzle is inserted into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
It remains possible to use a fuel jerrycan
to fill the tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a PEUGEOT dealer if the vehicle
is suitable for the distribution equipment of the
countries visited.
Hybrid system
Electrical system
The electrical system of the hybrid system is
identified by orange cables and its elements are
marked with this symbol:

The hybrid engine uses a voltage of between 240 V and 400 V. This system
may be hot during and after switching off the
ignition. Observe the warning messages on
the labels in the vehicle, especially in the flap.
Any work on or modification to the vehicle's
electrical system (battery, connectors, orange
cables and components visible from inside or
outside) is strictly prohibited due to the risk of
serious burns or electrical shock that can lead
to death.
In the event of a problem, always contact a
PEUGEOT dealer or a qualified workshop.


This label is intended solely for use by firefighters responding to an incident
involving the vehicle and for maintenance
technicians.
In the event of an accident or impact
The electrical system or the battery
may be seriously damaged in the event of
an accident or impact involving the vehicle
underbody.
Stop as soon as it is safe to do so and switch
off the ignition.
Contact a PEUGEOT dealer or a qualified
workshop without delay.
In the event of exposure to a fire
Immediately exit and evacuate all
passengers from the vehicle. Never attempt
to fight the fire yourself - risk of electrocution!
You must immediately contact the emergency
services, informing them that the incident
involves a hybrid vehicle.

When washing
Before washing the vehicle, always
check that the charging flap is closed
correctly.
Never wash the vehicle while the battery is
on charge.
High-pressure washing
To avoid damaging electrical
components, it is expressly prohibited to use
high-pressure washing to clean the front
compartment or the vehicle underbody.
Do not use a pressure greater than 80 bar
when washing the bodywork.
Never allow water or dust to enter the
connector or charging nozzle - risk of
electrocution or fire!
Never connect / disconnect the charging
nozzle or cable with wet hands - risk of
electrocution!
Traction battery
The Li-ion (Lithium-ion) traction battery stores
the electrical energy of the vehicle. It is located
under the rear seats.
The range of the battery varies depending
on the type of driving, the route, the use of
thermal comfort equipment and the ageing of its
components.
Battery ageing depends on several
parameters, such as climatic conditions,
mileage or charging frequency.
In case of damage of the battery
It is strictly forbidden to carry out repairs
on the vehicle yourself.
Do not touch liquids coming from the battery
and, in the event of skin contact with these
products, wash abundantly with water and
contact a doctor as soon as possible.
Charging flap
The charging flap is located on the rear left-hand
side of the vehicle.

Practical information
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a PEUGEOT dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a PEUGEOT
dealer or a qualified workshop.
Only use products recommended by
PEUGEOT or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, PEUGEOT selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a PEUGEOT dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of saturation of the particle filter is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37
mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust on
acceleration. This does not affect the
behaviour of the vehicle or the environment.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a PEUGEOT dealer or a qualified
workshop.

parking brake, refer to the
corresponding section.
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a PEUGEOT dealer or a
qualified workshop.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
