Driving
6The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (request for power, acceleration,
braking, etc.).
The system never suggests:
–

engaging first gear
.
–

engaging a lower gear
.
–

engaging reverse.
With a manual gearbox, the arrow may
be accompanied by the recommended
gear. The system always suggests changing
to a higher gear when this is necessary.
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 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.
Do 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. After that, ensure that the
parking brake indicator lamp and the indicator
lamp P in the electric parking brake control
lever are on fixed.
The hill start assist function cannot be deactivated. However, use of 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 you
release the brake pedal:
–

provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
This warning lamp comes on in the event of a malfunction, accompanied by an
onscreen message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Tyre 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.

76
Driving
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move 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.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
It is set via the Driving / Vehicle touch
screen menu.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
Associated indicator lamp
Function activated.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
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):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases 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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and 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 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
Reinitialise the system after adjusting one or
more tyre pressures 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 /
V
ehicle touch screen menu.
Malfunction
These warning lamps come on in the event of a malfunction.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a CITROËN dealer
or a qualified workshop.

In the event of a breakdown

► Connect the hose from the bottle of sealant
to the valve of the tyre to be repaired 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.
► Affix the speed limit sticker .
The speed limit sticker must be secured
to the interior of the vehicle in the area
close to the driver, to remind the driver that a
wheel is in temporary use.
The tyre inflation pressures are given on this label.


► Switch on the ignition.

► Switch on the compressor by moving switch
to position " I" until the tyre pressure reaches
2 bars. The sealant product is injected under
pressure into the tyre; do not disconnect the
pipe from the valve during this operation (risk of
blowback).
If after approximately 7 minutes the
pressure of 2 bars is not reached, this
indicates that the tyre is not repairable;
contact a CITROËN dealer or a qualified
workshop for assistance.
►

Move the switch to position " O

".
►

Disconnect the compressor's electric plug
from the vehicle's 12

V socket.
►

Refit the cap on the valve.
►


Remove the kit.
►


Remove and store the bottle of sealant.
The sealant product is harmful if swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle in
standard waste, take it to a CITROËN dealer
or an authorised waste disposal site.
Do not forget to obtain a new bottle of
sealant, available from a CITROËN dealer or
a qualified workshop.


► Drive immediately for approximately 3 miles
(5 kilometres) at reduced speed (between
12 and 37 mph (20 and 60
km/h)) to plug the
puncture.
►

Stop to check the repair
and the tyre
pressure using the kit.
With a tyre repaired using this type of kit,
do not exceed a speed of 50
mph
(80

km/h) and do not drive more than
125

miles (200 km).
Contact a CITROËN dealer or a qualified
workshop to have the tyre changed.
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 bars
is not reached, this indicates that the tyre
