Driving06
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
►  With a manual gearbox: with the clutch pedal
fully depressed.
►  With an automatic gearbox:
•

With the select
or in position D or M: with the
brake pedal released.
•

With the select
or in position N and the brake
pedal released: with the selector at D or M.
•

With the select
or in position P and the brake
pedal depressed: with the selector at R, N, D
or M.
•

R
everse gear engaged.
Special cases
The engine restarts automatically if all the
operating conditions are met again and in the
following cases.
–
With a manual gearbo
x: vehicle speed exceeds
2.5 mph (4 km/h),
–

With an aut
omatic gearbox, in mode N, vehicle
speed exceeds 0.6 mph (1 km/h).
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, this warning
lamp flashes for a few moments, then
remains on, accompanied by an onscreen
message.
Have the vehicle checked by a 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 "START/STOP" button.
The Stop & Start system requires a 12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a dealer or a qualified
workshop.
Under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
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.
The system triggers an alert as soon as it detects
a drop in the inflation pressure of one or more
tyres.
Under-inflation detection 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):
–

w
orsens road-holding.
–

lengthens braking dist
ances.
–

c
auses premature wear of the tyres.
–

increase
s fuel 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 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.
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.

94
Driving06
The loss of pressure detected does not
always cause visible bulging 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 the four tyres when cold.
►  If it is not possible to make 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).
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 is
reinitialised via the Driving / Vehicle touch
screen menu..
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Malfunction
These warning lamps come on in
the event of a malfunction.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a dealer or a
qualified workshop.
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 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.
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 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

Practical information07
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
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.
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 while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This 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 case of an issue, do
not hesitate to have the system checked by a
dealer or a qualified workshop.
For more information on the Electric
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 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

152In the event of a breakdown08
Checking / adjusting tyre
pressures
The compressor can be used, without injecting
sealant, to check and, if necessary, adjust the
tyre pressures.
► Remove the valve cap from the tyre and keep it
in a clean place.
►  Uncoil the pipe stowed under the compressor.
►  Screw the pipe onto the valve and tighten
firmly.
►  Check that the compressor switch is in
position "O".
►  Fully uncoil the electric cable stowed under
the compressor.
►  Connect the compressor's electric plug to the
vehicle's 12 V socket.
►  Switch on the ignition.
The tyre inflation pressures are given on
this label.


► Start the compressor by placing the switch
at position "I" and adjust the pressure to the
value shown on the vehicle's tyre pressure label.
To deflate: press the black button located on the
compressor pipe, near the valve connection.
If after 7 minutes the pressure of 2 bar is
not reached, the tyre is damaged; contact
a dealer or a qualified workshop for
assistance.
►  Once the correct pressure is reached, put the
switch in position "O".
►  Remove the kit and stow it.
Should the pressure of one or more tyres
be adjusted, it is necessary to reinitialise
the under-inflation detection system.
For more information on Tyre under-inflation
detection, refer to the corresponding section.
Spare wheel
Scan the QR Code on page 3 to view
explanatory videos.
For more information on the Tool kit, refer
to the corresponding section.
Access to the spare wheel

The spare wheel is stored under the boot carpet.
The spare wheel is a ‘space-saver’ wheel.
Removing the spare wheel

►  Slacken the central nut.
►  Remove the fastening device (nut and bolt).
►  Lift the spare wheel towards you from the rear.
►  Take the wheel out of the boot.
Putting the spare wheel back in place
The punctured wheel cannot be placed in
the boot under the floor.


► Put the spare wheel back in place in its
housing.
►  Slacken the nut on the bolt by a few turns.
►  Position the fastening device (nut and bolt) in
the middle of the wheel.
►  Tighten the central nut sufficiently to retain
the wheel correctly.
►  Depending on version, put the tool box back
in place in the middle of the wheel and clip it in
place.
Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not
obstruct traffic: the ground must be level,
stable and non-slippery.
With a manual gearbox, engage first gear
to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
With an automatic gearbox, select mode P
to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
