Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
these systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
th

e ABS prevents wheel lock in the event of
emergency braking.
th

e electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed.
t
h
is is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
this system (also known as tr action Control)
optimises traction in order to avoid wheel
slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.

Dynamic stability control (DSC) and anti-slip regulation (ASR)
Activation
these systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
th
is is indicated by flashing of this
warning lamp in the instrument panel.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
DSC system, so that the wheels can spin freely
and regain grip.
th
e DSC system offers exceptional
safety in normal driving, but this should
not encourage the driver to take extra
risks or drive at high speed.
th
e correct operation of the system
depends on observation of the
manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the P
e
uge
Ot

assembly and operation procedures.
After an impact, have the system
checked by a P
e

uge
Ot
dealer or a
qualified workshop.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the system.
Contact a P
e

uge
Ot
dealer or a qualified
workshop to have the system checked.
Reactivation
the system is reactivated automatically each
time the ignition is switched back on or from
12
mph (20 km/h).

reactivate it manually.

Driving advice
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F take into account the increased sensitivity to side wind.
Cooling
towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F
t
o l
ower the engine speed, reduce your
speed.
th

e maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
Braking
towing a trailer increases the braking distance.to a void overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
th

e rear parking sensors will be
deactivated automatically if a genuine

of the weights and towed loads which apply to
your vehicle.

Electronic gearbox
the gearbox does not require any
maintenance (no oil change).
Refer to the warranty and
maintenance record for details
of the checking interval for this
component.
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

Particle filter (Diesel)
the start of saturation of the
particle filter is indicated by the
temporary illumination of this
warning lamp accompanied by
a message in the multifunction
screen.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, this
indicates a low additive level.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
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 on acceleration.

between vehicle services.

the brake fluid level indicates that the brake

Brake disc wear Electric parking brake
this system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a P
e

uge

dealer or a
qualified workshop. Only use products recommended by
P
e

uge

or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, P

selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
