Safety
5Electronic stability control 
(ESC)
The electronic stability control programme includes the following systems:
–
 
Anti-lock braking system (ABS) and Electronic 
brake force distribution (EBFD).
–
 
Emergency braking assistance (EBA).
–
 
Anti-slip regulation (ASR).
–
 
Dynamic stability control (DSC).
–
 
T
 railer stability assist (TSA).
Anti-lock braking system (ABS)/Electronic brake force 
distribution (EBFD)
These systems enhance the vehicle’s stability 
and handling during braking, and enable greater 
control while cornering, particularly on poor or 
slippery road surfaces.
ABS prevents wheel locking in the event of 
emergency braking.
Electronic brake force distribution (EBFD) 
manages overall braking pressure on each 
individual wheel.
►
 
When braking in an emergency
 , depress 
the pedal very firmly and maintain this 
pressure.
Normal operation of the ABS may make 
itself felt by slight vibrations of the brake 
pedal.
The fixed illumination of this warning lamp  signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive 
carefully at a moderate speed.
Have it checked by a PEUGEOT dealer or a 
qualified workshop.
This warning lamp, when lit together with  the STOP and ABS warning lamps, 
accompanied by a message and an audible 
signal, indicates an EBFD malfunction.
You must stop the vehicle.
Stop as soon as it is safe to do so and switch off 
the ignition.
Contact a PEUGEOT dealer or a qualified 
workshop.
When changing wheels (tyres and rims), 
ensure that these are approved for your 
vehicle.
After an impact
Have it checked by a PEUGEOT dealer 
or a qualified workshop.
Emergency braking 
assistance (EBA)
This system reduces the emergency stopping 
distance, by optimising the braking pressure.
It is triggered in relation to the speed at which 
the brake pedal is depressed. The effect of this 
is a reduction in the resistance of the pedal and 
an increase in braking efficiency.
Anti-slip regulation (ASR)/ Dynamic stability control 
(DSC)
Anti-slip regulation (or traction control) optimises 
traction by using engine braking and by applying 
the brakes on the driving wheels to avoid one 
or more wheels spinning. It also enhances the 
vehicle's directional stability.
If there is a difference between the vehicle’s 
trajectory and the path desired by the driver, the 
dynamic stability control system automatically 
uses engine braking and the brakes on one or 
more wheels to return the vehicle to the desired 
path, within the limits of the laws of physics.
These systems are activated automatically every 
time the vehicle is started.
These systems are activated in the event of a problem with grip or trajectory 
(confirmed by this warning lamp flashing on the 
instrument panel).
PSE (PEUGEOT Sport Engineered)
The dynamic stability control is optimised 
to be able to react later on this vehicle.
Deactivation/Reactivation
In exceptional conditions (e.g. moving a vehicle 
that is bogged down in mud, stuck in snow , on 
loose soil), it may prove useful to deactivate the 
DSC/ASR systems, so that the wheels can move 
freely and regain grip.    
Page 84 of 244
82
Safety
Reactivate the system as soon as the level of 
grip permits.
The ASR system is deactivated/reactivated in the  ADAS touch screen 
application.
Deactivation/reactivation of the ASR 
system is indicated by this indicator lamp 
on the instrument panel coming on/going out and 
the display of a message.
The ASR system is automatically reactivated 
every time the ignition is switched off or at 
speeds over 31 mph (50 km/h)
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning 
lamp lights up on the instrument panel, 
accompanied by the display of a message and 
an audible signal.
Have it checked by a PEUGEOT dealer or a 
qualified workshop.
ASR/DSC
These systems enhance safety during 
normal driving, but should not encourage 
the driver to take extra risks or drive at high 
speed.
It is in conditions of reduced grip (rain, snow, 
ice) that the risk of loss of grip increases. It 
is therefore important for your safety to keep 
these systems activated in all conditions, and 
particularly in difficult conditions.
Correct operation of these systems depends 
on compliance with the manufacturer's 
recommendations relating to the wheels 
(tyres and rims), braking and electronic 
components, as well as the assembly and 
repair procedures provided by PEUGEOT 
dealers.
In order to ensure that these systems remain 
effective in wintry conditions, the use of snow 
or all-season tyres is recommended. All four 
wheels must be fitted with tyres approved for 
your vehicle.
All tyre specifications are listed on the 
tyre/paint label. For more information 
on Identification markings , refer to the 
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the 
vehicle or trailer snaking.
Operation
The system is activated automatically when the 
ignition is switched on.
The electronic stability control system (ESC) 
must not have any faults.
The vehicle speed must be between 37 and 99 
mph (60 and 160
  km/h).
If the system detects that the trailer is 
snaking, it applies the brakes to stabilise 
the trailer and reduces engine power, if 
necessary, to slow the vehicle (indicated by the 
flashing of this warning lamp on the instrument 
panel and the brake lamps coming on).
For more information on weights and towed 
loads, refer to the Engine technical data 
and towed loads  section or your vehicle’s 
registration certificate.
To ensure safe driving with a  Towing device, 
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights 
up on the instrument panel, accompanied 
by a message and an audible signal.
To continue towing a trailer, reduce speed and 
drive carefully!
Have it checked by a PEUGEOT dealer or a 
qualified workshop.
The trailer stability control system  provides an extra safety feature under 
normal driving conditions, when following the 
recommendations for use of trailers and 
current legislation in force in your country. It 
must not encourage the driver to take extra 
risks, such as using a trailer in unsuitable 
conditions of operation (e.g.
  excessive load, 
exceeded nose weight, worn or under-inflated 
tyres, faulty braking system) or driving at 
excessive speed.
In certain cases, the system may not detect 
trailer snaking, particularly with a light trailer.

Driving
6Driving recommendations
► Observe the driving regulations and remain 
vigilant whatever the traffic conditions.
►
 
Monitor your environment and keep your 
hands on the wheel to be able to react to 
anything that may happen any time.
►
 
Drive smoothly
 , anticipate the need for 
braking and maintain a longer safety distance, 
especially in bad weather.
►
 
Stop the vehicle before performing operations 
that require sustained attention (e.g.
  settings).
►
 
During long trips, take a break every 2 hours.
Important!
Never leave the engine running in a 
closed space without sufficient 
ventilation.  Internal combustion engines emit 
toxic exhaust gases such as carbon 
monoxide. Danger of poisoning and death!
In very severe wintry conditions 
(temperature below -23°C), let the engine 
run for 4 minutes before moving off, to ensure 
the correct operation and durability of the 
mechanical components of your vehicle 
(engine and gearbox).
Never drive with the parking brake 
applied . Risk of overheating and 
damaging the braking system!
Never park the vehicle and never 
leave the engine running on a 
flammable surface (e.g.
  dry grass, dead 
leaves).The vehicle exhaust system is very 
hot, even several minutes after the engine 
stops. Risk of fire!
Never drive on surfaces covered with 
vegetation (e.g.   tall grass, 
accumulated dead leaves, crops, debris) 
such as a field, a country lane overgrown 
with bushes or a grassy verge.
This vegetation could come into contact with 
the vehicle's exhaust system
  or other systems 
which are very hot. Risk of fire!
Make sure you do not leave any item in 
the passenger compartment which could 
act like a magnifying glass under the effect of 
the sun's rays and cause a fire. Risk of fire or 
damage to interior surfaces!
Never leave the vehicle unattended, 
with the engine running . If you have to 
leave your vehicle with the engine running, 
apply the parking brake and put the automatic 
gearbox into position  N or P.
Never leave children inside the vehicle 
unsupervised.
PSE (PEUGEOT Sport Engineered)
Repeated hard braking in this vehicle 
can generate loud banging noises which are 
completely normal.
Continue driving but with lighter braking so 
that the braking system can cool down.
The
 
performance   of the   braking system 
remains unaffected.
On flooded roads
We strongly advise against driving on flooded 
roads, as this could cause serious damage to 
the internal combustion engine or electric motor, 
the gearbox and the electrical systems of the 
vehicle.
 
 
If the vehicle absolutely must drive through a 
flooded section of road:
►
 
Check that the depth of the water does not 
exceed 15
  cm, taking account of waves that 
might be generated by other users.
►
 
Deactivate the Stop & Start function.
►
 
For rechargeable hybrid engines, place the 
mode selector in  4WD
 position (depending on 
version).   
Page 100 of 244
98
Driving
► Drive as slowly as possible without stalling. In 
all cases, do not exceed 6 mph (10   km/h).
►
 
Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety 
conditions allow
, make several light brake 
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, 
contact a PEUGEOT dealer or a qualified 
workshop.
Towing
Driving with a trailer places greater 
demands on the towing vehicle and 
particular care must be taken.
Do not exceed the maximum towable 
weights.
At altitude: reduce the maximum load by 
10% per 1,000 metres of altitude; the lower 
air density at high altitudes decreases engine 
performance.
New vehicle: do not tow a trailer until the 
vehicle has driven at least 620 miles 
(1,000 kilometres).
If the outside temperature is high, let the 
engine idle for 1 to 2 minutes after the 
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the 
heaviest items are as close as possible to the 
axle and the nose weight (at the point where it 
joins your vehicle) approaches the maximum 
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing 
vehicle and of the trailer , observing the 
recommended pressures.
Lighting
► Check the electrical signalling on the trailer 
and the headlamp beam height of your vehicle.
If a genuine PEUGEOT towing device is 
used, the rear parking sensors will be 
deactivated automatically to avoid the audible 
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant 
temperature to increase. The maximum towable 
load depends on the gradient and the exterior 
temperature. The fan’s cooling capacity does not 
increase with engine speed.
►
 
Reduce speed and lower the engine speed to 
limit the amount of heating produced. ►
 
Pay constant attention to the coolant 
temperature.
If this warning lamp and the STOP 
warning lamp come on, stop the 
vehicle and switch off the engine as soon as 
possible.
Brakes
Using the engine brake is recommended to limit 
the overheating of the brakes. Braking distances 
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more 
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be 
recognised by the vehicle before starting is 
possible.
If the system malfunctions, indicated by the 
display of a message, the engine will not start.
Contact a PEUGEOT dealer.
