TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
Activation of the ASR and ESP
systems
When the ignition is on, the ASR and
ESP systems are always active.Disarming the ASR/ESP systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...), it
could prove useful to disarm the ASR
and ESP systems to make the wheels
spin and regain grip.
- Press the switch, situated under the
steering wheel on the right of the
fascia.
The indicator light comes on
accompanied by a message:
the ESP and ASR systems
no longer act on the engine
operation, but continue to act
on the brakes. Operating check
The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the
driver to take risks or to drive at high
speed.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the itting and repair
procedures within the PEUGEOT
network are observed.
After an impact, have the system
checked by a PEUGEOT dealer.
They engage again:
F
automatically above 30 mph
(50 km/h),
F manually by pressing the switch
again.
Operation of the ASR
and ESP systems
The warning light lashes if
the ASR or ESP is activated.
These systems are linked and
complement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by acting
on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to be
improved on acceleration.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course, within the limits of the laws
of physics.
When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Contact a PEUGEOT dealer to have
the system checked.

Driving safety
TYRE UNDER-INFLATION
DETECTION
Sensors check the tyre pressure during
driving, and trigger a warning in the
event of a malfunction (speed greater
than approx.15 mph [25 km/h]) or
puncture.
An outline representing one or more
wheels lashing indicates the location
of the wheel or wheels concerned.Flat tyre
The SERVICE warning light
comes on, accompanied
by the message "Tyre(s)
delated" , an outline on the display,
and an audible signal.
Check the tyre pressure as soon as
possible. If the damaged tyre is temporarily
stored in the boot, it will again emit
this message to remind you of the
necessity of having it repaired. This will
prevent another warning of the same
type being displayed.
Sensor(s)
not detected
The SERVICE warning light
comes on, accompanied
by the message "X tyre pressure
sensor(s) missing" , an outline on the
display and an audible signal.
Under-inlation detection is absent
from one (or several) tyre(s). Consult a
PEUGEOT dealer to replace the faulty
sensor(s). This message is also displayed
when one of the tyres is away
from the vehicle (being repaired)
or when a wheel without a sensor is
itted.
All repairs and changing of
tyres on a wheel itted with this
system must be carried out by a
PEUGEOT dealer.
The tyre under-inlation detection
system is a driving aid which does
not take the place of vigilance or the
responsibility of the driver.
This system does not remove the
need to have the tyre pressure
checked regularly (including the spare
wheel), to ensure that the dynamic
performance of the vehicle remains at
its best and to avoid premature wear
of the tyres, in particular in the case
of arduous driving (heavy load, high
speed).
The system may temporarily be
disturbed by radio broadcasts on a
frequency close to it.
Puncture
The STOP warning light
comes on, accompanied
by the message
"Punctured tyre(s)" , an outline on the
display and an audible signal.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged (punctured or
very delated) tyre, and have the tyre
pressure checked as soon as possible.
Refer to the "Changing a wheel"
section of chapter 8.

Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature. Brakes:
towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually. Please contact a PEUGEOT dealer
irst for further information.
Automatic adjustment
For vehicles with Xenon bulbs, this
system automatically corrects the
height of the beam, whatever the
load of the vehicle. The driver is then
assured of having optimum lighting and
not causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power.
In this case, cutting off the air
conditioning allows the engine power
to be recovered, and therefore the
towing speed to be signiicantly
increased (approximately 12 mph
[20 km/h] more). Sequential control
of the gearbox may also become
unavailable. Lighting
Bicycle carrier If you it a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display’s
coniguration menu.
Refer to the "Identiication
features" section of chapter 9. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 8.
If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.
Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure. Side wind:
sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
PEUGEOT towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be itted in
accordance with the manufacturer’s
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this itting
should be carried out by a professional,
we recommend that you entrust the
itting of this equipment to a PEUGEOT
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with itting a towbar or other electrical
accessory which is not recommended
by the PEUGEOT network. Fitting such
equipment could result in a failure of
your vehicle’s electronic system. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
