Driving
6Effective eco-driving saves fuel; accelerate 
progressively, anticipate the need to slow down 
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so 
that you are seen by other road users.
Take care
The tyres must be inflated to at least the 
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys. 
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 CITROËN dealer or a qualified 
workshop.
In case of towing
Driving with a trailer places greater 
demands on the towing vehicle and 
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by 
10% per 1,000 metres of altitude; the density 
of the air decreases with altitude and the 
performance of the engine reduces.
New vehicle: do not pull a trailer before 
having 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 CITROËN towing device is 
used, the rear parking sensors will be 
deactivated automatically to avoid the audible 
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature 
of the coolant. The maximum towable load 
depends on the gradient and the exterior 
temperature. The cooling capacity of the fan 
does not increase with engine speed.
►  Reduce speed and lower the engine speed, 
so as to limit the heating-up.
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.
