Special aspects of automatic
mode
For maximum acceleration without touching the
selector, push the accelerator to the floor (kick-
down). The gearbox shifts down automatically
or holds the gear selected until the maximum
engine speed is reached.
The steering mounted controls allow the driver
to temporarily select a gear, if the road and
engine speed permit.
Special aspects of manual mode
The change from one gear to another takes
place only if the road speed and engine speed
permit.
Starting the vehicle
The gearbox selects the gear that offers
optimum per formance, taking account of the
exterior temperature, the profile of the road, the
load on the vehicle and the style of driving.From mode P

operation and durability of the engine and
gearbox.
Stopping the vehicle
Whatever the state of the gearbox when the
ignition is switched off, mode P is engaged
automatically and immediately.
However, in mode N , mode P will be engaged
after a duration of 5 seconds (allowing for the
process of putting the vehicle to free-wheeling).
Check that mode P has been engaged and that
the electric parking brake has been applied
automatically; if not, apply it manually.
Gearbox operating fault
The corresponding indicator lamps in
the selector and the electric parking
brake control lever must be on, as well
as those in the instrument panel.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This system only operates when:
-

t
he vehicle has been brought to a complete
stop, with your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

w
ith the driver’s door closed.
This is signalled by the illumination
of this warning lamp, accompanied
by the display of a message and an
audible signal, when the ignition is
switched on.
Go to a PEUGEOT dealer or a qualified
workshop.
Do not drive faster than 62 mph (100

km/h),
keeping to the speed limit.
The gearbox switches to back-up mode: mode
D is locked in third gear, the steering-mounted
control paddles are inoperative, mode M is no
longer available. You may feel a pronounced
jolt when engaging reverse. This does not
present any risk for the gearbox.
Selector operating fault
Minor malfunction
You are alerted by this warning lamp
lighting up, accompanied by the
display of a message and an audible
signal.
Drive cautiously and go to a PEUGEOT or a
qualified workshop.
Major malfunction
You are alerted by the illumination of
this warning lamp.
Stop as soon as it is safe to do so, away
from the traffic, and call a PEUGEOT
dealer or a qualified workshop.
When the ignition is switched off, the
gearbox goes into mode P automatically.
In certain cases, the selector lamps may not
come on, but the state of the gearbox is still
displayed in the instrument panel.

Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp and the indicator
lamp P in the control lever of the electric
parking brake 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
Uphill, with the vehicle stationar y, the
vehicle is held for a shor t time when you
release the brake pedal:
-
p
rovided you are in first gear or neutral on a
manual gearbox.
-

p
rovided you are in mode D or M with an
automatic gearbox. Downhill, with the vehicle stationary and
reverse gear engaged, the vehicle is held
for a shor t time when you release the brake
pedal.
Operating fault
If a fault in the system occurs, these warning
lamps come on.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
Active Suspension
Control
This suspension can modulate itself to the
following parameters: state and profile of the
road, load of the vehicle, driving style and
selected driving mode.
The mode can be selected using the driving
modes control on the central console.
For more information on the Driving modes
,
refer to the corresponding section. It is managed by a control unit, which interprets
the data transmitted by different sensors to
apply the optimal level of damping to each
shock absorber according to these parameters.
It offers three modes: Comfort , Normal and
Sport .
In Comfort mode, it favours soft damping to
improve comfort on poor road sur faces.
In Normal mode, it offers the best compromise
between comfort and handling.
In Sport mode, it favours firm damping to limit
body movements.
Driving modes
These various driving modes offered
correspond to specific vehicle settings.
This choice of driving modes depends on the
vehicle’s equipment.
Each time the ignition is switched on, " Normal"
is selected by default.

Choice of a mode
When the message goes off, the selected
mode is activated and remains indicated in the
instrument panel (except for "Normal" mode). ECO, Comfor t, Normal, Spor t, Manual.
Pressing the control displays the modes in the
instrument panel.
Gear shift indicator
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be deactivated.With an automatic gearbox, the system is
only active in manual mode. The information appears in the
instrument panel in the form of an
ascending or descending arrow and
a recommended gear.
The system adapts its gear efficiency
recommendation according to the driving
conditions (slope, load, etc.) and the
driver’s requirements (power, acceleration,
b r a k i n g , e t c .) .
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams, etc.).
The engine restarts automatically – START
mode – as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the key or the " START/STOP" button.
Operation
Going into engine STOP mode

A time counter calculates the time spent in
STOP mode during the journey. It is reset to
zero every time the ignition is switched on with
the "START/STOP " button.
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear or turning the steering wheel.
The Stop & Start does not affect the
operation of vehicle systems, such as

button.
Tyre under-inflation
detection
This system automatically monitors the tyre
pressures while driving.
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised ever y 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. The Stop & Start system requires a
12
V battery of specific technology and
specification.
All work on this type of battery must be
carried out only by a PEUGEOT dealer or
a qualified workshop.
For more information on the 12 V batter y

For this purpose there is a camera located at the
top of the windscreen, and, depending on the
version, a radar installed in the front bumper.Primarily designed for driving on main
roads and motor ways, this system only
works on moving vehicles , driving in the
same direction as your vehicle.
Principle of operation
The system automatically adapts the speed of
your vehicle to that of the vehicle in front, to
maintain a constant distance.
If the vehicle in front is driving more slowly,
the system slows, or even stops your vehicle,
using engine braking and the braking system
(for versions fitted with an automatic gearbox).
For versions fitted with the EAT8 automatic
gearbox, if traffic conditions allow and the
stop was for less than 3 seconds, your vehicle
restarts automatically.
If the vehicle in front accelerates or changes
lane, the cruise control progressively
accelerates your vehicle to return to the
programmed speed. The brake lamps illuminate as soon as
the braking system is activated with
deceleration of the vehicle.
This system is a driving aid that cannot,
in any circumstances, replace the need to
obser ve speed limits and safety distances,
nor the need for vigilance on the part of
the driver.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar
(e.g. a lorry), which may lead to a poor
assessment of the distances and lead to
the vehicle inappropriately accelerating or
braking.
The driver must be ready at all times
to retake control of their vehicle by
permanently holding both hands on the
steering wheel and keeping their feet near
the brake and accelerator pedals.
If the driver operates a direction indicator to
overtake a slower vehicle, the cruise control
allows your vehicle to temporarily approach
the vehicle in front to assist the overtaking
manoeuvre, though never exceeding the
programmed speed.
vehicle to come to a complete stop.
For the versions fitted with the EAT8 gearbox,
your vehicle can restart automatically. The cruise control remains active after
changing gear regardless of the gearbox
type.
It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system.
Adaptive cruise control
This system provides the following
functions:
-

A
utomatically maintains the vehicle
at the speed set by the driver.
-

A
utomatic adjustment of the
distance between your vehicle and
the one in front.
With an automatic gearbox, automatic
