2014 Citroen DS5 HYBRID4 engine

245Practical information
DS5-HYBRID_EN_CHAP08_INFO PRATIQUES_ED02-2013
We recommend the use of genuine CITROËN towbars and their harnesses that have been tested and approved from the design stage of your vehicle, and that the fitting of the towbar is
entrusted to a CITROËN dealer or a qualified workshop. If the towbar is not fitted by a CITROËN dealer, it is imperative that it is fitted in accordance with the vehicle manufacturer's instructions.
Driving advice
Distribution of loads
 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
 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.  To lower the engine speed, reduce your speed.
 If 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 avoid overheating of the brakes on a long mountain type of descent, the use of engine braking is recommended.
Ty r e s
 Check the tyre pressures of the towing vehicle and of the trailer, observing the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.
Driving with a trailer places greater demands on the towing vehicle and the driver must take particular care.
The 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.
Refer to the "Technical data" section for details of the weights and towed loads which apply to your vehicle.

Opening the bonnet
Opening
 From inside : pull the release lever, located on the left below the dashboard, towards you.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
Closing
 Lower the bonnet and release it at the end of its travel.  Check that it is latched correctly.
 From the outside : lift the safety catch and raise the bonnet. A bonnet strut opens the bonnet and holds it open.
Never touch, handle or remove the orange "high voltage" cables.
Because of the presence of electrical equipment under the bonnet, it is recommended that exposure to water
(rain, washing, ...) be limited.

On vehicles fitted with HDi engines, the fuel system must be primed if you run out of fuel; refer to the corresponding engine compartment view.
Running out of fuel (Diesel)
If the tank on your vehicle is fitted with a misfuel prevention device, refer to the "Misfuel prevention (Diesel)" section.
 Fill the fuel tank with at least five litres of Diesel.  Open the bonnet.  If necessary, unclip the style cover for access to the priming pump.  Slacken the bleed screw.  Squeeze and release the priming pump repeatedly until fuel appears in the transparent pipe.  Tighten the bleed screw.  Operate the starter until the engine starts (if the engine fails to start at the first attempt, wait around 15 seconds before trying again).  If the engine fails to start after a few attempts, operate the priming pump again, then the starter.  Put the style cover back in position and clip it in place, ensuring that it has clipped c o r r e c t l y.  Close the bonnet.
2 litre HDi engine
If the engine does not start first time, don't keep trying but start the procedure again from the beginning.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any time (even with the ignition off).
Engine oil level
The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel for vehicles with and electric oil level gauge, or using the dipstick.
To ensure that the reading is correct, your vehicle must be parked on a level sur face and the engine having been off for more than 30 minutes.
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
It is normal to top up the oil level between two services (or oil changes). CITROËN recommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms).
Checking using the dipstick
Refer to the "Diesel engine" section for the location of the dipstick in the engine compartment of your vehicle.
 Take the dipstick by its coloured grip and remove it completely.  Wipe the end of the dipstick using a clean non-fluffy cloth.  Refit the dipstick and push fully down, then pull it out again to make the visual check: the correct level is between the marks Aand B .

A = MA X
B = MIN
If you find that the level is above the A mark or below the B mark, do not star t the engine . - If the level is above the MAX mark (risk of damage to the engine), contact a CITROËN dealer or a qualified workshop. - If the level is below the MIN mark, you must top up the engine oil.
Oil grade
Before topping-up the oil or changing the oil, check that the oil is the correct grade for your engine and conforms to the manufacturer's recommendations.
Topping up the engine oil level
Refer to the "Diesel engine" section for the location of the oil filler cap in the engine compartment of your vehicle.  Unscrew the oil filler cap to reveal the filler aperture.  Add oil in small quantities, avoiding any spills on engine components (risk of fire).  Wait a few minutes before checking the level again using the dipstick.  Add more oil if necessary.  After checking the level, carefully refit the oil filler cap and the dipstick in its tube.
After topping up the oil, the check when switching on the ignition with the oil level indicator in the instrument panel is not valid during the 30 minutes after topping up.
Engine oil change
Refer to the maintenance and warranty guide for details of the interval for this operation. In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.

The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the maintenance and warranty guide for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
The power steering fluid level should be close to the "MA X" mark. With the engine cold, unscrew the cap to check the level.
Power steering fluid level
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
When the engine is warm, the temperature of the coolant is regulated by the fan.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.
