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.

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.

LOW FUEL LEVELThe tank must be illed with fuel with
the engine off
.
- Open the fuel iller lap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to the
clip located on the inside of the lap.
FILLING THE FUEL TANK
When the fuel iller lap is open, a
system limits the opening of the
rear left sliding side door.
The key cannot be removed from the
cap’s lock until the cap is reitted on
the tank.
FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine.
The lashing of this warning
light is accompanied by a
message on the display.
When the tank’s minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel
level low" on the display.
You have enough fuel left to cover
approximately 30 miles (50 km) ,
depending on driving conditions and
the engine.
If the warning light lashes, this
indicates a fuel gauge malfunction.
Consult a PEUGEOT dealer.
DIESEL REPRIMING PUMP
If you should run out of fuel, it is
necessary to re-prime the circuit:
- ill the fuel tank with at least ive litres of diesel,
- squeeze and release the manual re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,
- operate the starter until the engine starts.
A label on the inside of the lap
indicates which type of fuel to use.
If you ill your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
The capacity of the tank is
approximately 18 gallons (
80 litres).
- After illing the tank, lock the cap
and close the lap. Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:

instructions at PEUGEOT dealerships,
on the Service Box site or in the
servicing booklet enclosed in the
handbook pack. To maintain the reliability of engines
and emission control systems, the use
of additives in engine oil is prohibited.
Oil change
It is imperative that this is carried out at
the intervals speciied and the viscosity
grade of the oil selected must fulil the
requirements in accordance with the
manufacturer’s servicing schedule.
Consult the instructions at PEUGEOT
dealerships or on the Service Box site.

A = maximum
If you ill past this
mark, contact a
PEUGEOT dealer.
B = minimum
Never allow the level
to fall below this
mark. Warning lights
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
Viscosity selection
In all cases, the oil selected must meet
the manufacturer’s requirements. Checking by means of the
warning lights on the instrument
panel is described in chapter 2,
"Instruments and controls" section.
Changing the brake fluid
The brake luid must be changed at
the intervals stated, according to the
manufacturer’s servicing schedule.
Use luids recommended by the
manufacturer, which fulil DOT4
standards.
The level must be between the MIN
and MAX marks on the reservoir.
If luid has to be added frequently,
this indicates a failure which must be
checked by a PEUGEOT dealer as
soon as possible.

Cooling system
Only use the luid recommended by the
manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
If luid has to be added frequently,
this indicates a failure which must be
checked by a PEUGEOT dealer as
soon as possible.Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks.
During regeneration of the particle
emission ilter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a PEUGEOT dealer.
Diesel additive level (Diesel with
particle emission filter) The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission ilter (exceptionally
prolonged urban driving conditions: low
speed, long trafic jams, ...).
In order to regenerate the ilter, you
are advised to drive at a speed of
more than 40 mph (60 km/h) as soon
as possible, when trafic conditions
permit, for at least ive minutes (until
the message disappears and the
service warning light is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of luid is
required to top up the level, have
the system checked by a PEUGEOT
dealer. Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the PEUGEOT Universal
range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a PEUGEOT dealer
without delay.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake luid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
luid or coolant into drains or onto
the ground but into the containers
dedicated to this use at PEUGEOT
dealerships.
