2012.5 Citroen DS5 RHD engine

217Practical information

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 b
y 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. The maximum towed load on a long inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and theSTOPwarning lamp come on, stop the vehicle and switch off
the engine as soon as possible.



Braking

To w i ng 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.


Tyres
)
Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.



The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.

view.











Running out of fuel (Diesel)


If the tank on your vehicle is fitted witha 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 styling cover for
access to the priming pump.
) Squeeze and release the priming pump
repeatedly until resistance is felt (there may
be resistance at the first press). ) Operate the star ter until the engine starts(if the engine does not star t at the first
attempt, wait around 15 seconds before
trying again). ) If the engine does not star t after a few
attempts, operate the priming pump again
then start the en
gine. ) Clip the styling cover back in place.
)
Close the bonnet.

transparent pipe.
)Tighten the bleed screw. )Operate the star ter until the engine star ts (if the engine fails to star t at the first attempt, wait around 15 seconds before
trying again).)If the engine fails to star t after a fewattempts, operate the priming pump again,

If the engine does not star t first time, don't keep trying. Start the procedure
again from the beginning.

229Checks






Checking levels


Take care when working under thebonnet, as certain areas of the enginemay be extremely hot (risk of burns).
Oil level

The check is carried out either when
the ignition is switched on using the oil level indicator on the instrument
panel, or using the dipstick.

Engine oil change

Refer to the ser vicing booklet for details of the
interval for this operation.
In order to maintain the reliabilit
y of the engine
and emission control system, the use of
additives in the engine oil is prohibited.

Oil specifi cation

The oil must be the correct grade for your engine and conform to the manufacturer's
recommendations.
After topping up the oil, the check whenswitching on the ignition with the oillevel indicator in the instrument panelis not valid during the 30 minutes after topping up.
If a level drops significantly, have the corresponding system checked by a CITRO
ËN dealer or a qualified workshop.
Check all of these levels regularly, in line with the ser vicing booklet and the requirements of the warranty. Top them up if necessary, unless other wise indicated.
This manual check will onl
y be correct if the
vehicle is on level ground and the engine has
been off for more than 30 minutes.
It is normal to top up the oil level between
two ser vices
(or oil changes). CITROËNrecommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms).

Coolant level
The coolant level should be closeto the "MA X" mark but should never exceed it.

Changing the coolant
The coolant does not have to be changed.


Fluid specifi cation

The coolant must conform to themanufacturer's recommendations.
Power steering fluid level

The power steering fluid level shouldbe close to the "MA X" mark. With
the engine cold, unscrew the cap tocheck the level. Th
e 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 ser vicing booklet for details of the
interval for this operation.
Fluid specifi cation
The brake fluid must conform to themanufacturer's recommendations and meet the
DOT4 standard.
In addition, as the cooling system ispressurised, wait at least one hour after
switching off the engine before carrying out any work.To a v o i d a ny risk of scalding, unscrewthe cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and topup the level. When the en
gine is warm, the temperature of
the coolant is regulated by the fan. This can
operate with the ignition off.
For vehicles fitted with a
par ticle emissions
filter, the cooling fan may continue to
run after stopping the vehicle, even if theengine is cold.

231Checks
Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water.

Screenwash / headlamp
wash level
To check the level or top up the fluid on vehicle fitted with headlamp washers, immobilise the
vehicle and switch of the engine. )Before opening the bonnet, ensure that the engine has completely stopped. )Open the screenwash reser voir filler cap.
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful tohealth or indeed very corrosive.

Do not discard used oil or fluids into sewers or onto the ground.

Take used oil to a CITROËN dealer or a qualified workshop (France) or to anauthorised waste disposal site.








Used products

Topping up

This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay.

Diesel additive level
(Diesel engine with particle
emission filter)

A low additive level is
indicated by illumination of
the ser vice warning lamp,
accompanied by an audible warning and a
message in the instrument panel screen.
) Take and pinch the level gauge to block its breather.)
Remove the gauge completely from
the reservoir to read the level in thetransparent section.) To p u p if necessary.)
Refit the filler cap to the reser voir andclose the bonnet.

Checks
12 V battery
The battery does not require any maintenance.
However, check that the terminals
are clean and correctly tightened,particularly in summer and winter.
The presence o
f this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop is
essential when replacing or disconnecting the
battery.
Unless otherwise indicated, check these
components in accordance with the servicing
booklet and according to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
When carr
ying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnectingthe battery and following its reconnection.
