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).

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.
