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 to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
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 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
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
►

deactivate the Stop & Start function,
►


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).

Driving
Starting with the key
The parking brake must be applied.
► With a manual gearbox in neutral, fully
depress the clutch pedal.
► With an automatic gearbox in mode P or N,
fully depress the brake pedal.
► Insert the key into the ignition switch.
– The system recognises the starting code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In some cases, you may have to apply
some force to turn the wheels (if the
wheels are turned against a kerb, for
example).
► With a petrol engine, operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. As soon as the engine starts, release the
key.
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
► Wait until this warning lamp goes off in
the instrument panel, then turn the key to
position 3 without pressing the accelerator pedal,
to operate the starter motor until the engine
starts. As soon as the engine starts, release the
key.
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.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes after
the ignition is switched off, and prevents the
engine being started by anyone who does not
have the key.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message in the screen.In
this case, your vehicle will not start; contact a
PEUGEOT dealer as soon as possible.
Keep safely, away from your vehicle, the
label attached to the keys given to you
when you purchased your vehicle.

Emergency braking
Emergency braking should only be used
in exceptional circumstances.
In the event of a fault with the brake pedal or
in exceptional circumstances (e.g. driver taken
ill, driver under instruction, etc.), a continuous
pull on the control lever will brake the vehicle.
Braking takes place as long as the control lever
is being pulled. Braking stops when the control
lever is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If the emergency braking malfunctions, the
"Parking brake faulty” message will be displayed.

If the ABS and DSC systems malfunction,
signalled by the illumination of one or both
warning lamps in the instrument panel, then
stability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever until the vehicle is
immobilised.
