Towing a trailer
Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Side wind
F Take into account the increased sensitivity to side wind.
Driving advice
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.
F

T
o lower the engine speed, reduce your
speed.
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.
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 must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care.
Distribution of loads
F 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 per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle. F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Practical information

223
Blanking cover
When towing, you must remove the blanking
cover in the front bumper as well as the bonnet
seal if fitted.
Contact a CITROËN dealer or a qualified
workshop for this.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
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.

Checks

235
Checking levels
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 an electric oil
level gauge, or using the dipstick.
Check all of these levels regularly, in line with the manufacturer's service schedule. 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.
If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top up the engine oil.
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).
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine having been off for more than
30 minutes.
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

section for the location of the dipstick in the
engine compartment of your vehicle.

check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
Topping up the engine oil level

section for the location of the oil filler cap in the
engine compartment of your vehicle.

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 manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Checks

237
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
Power steering or power
steering and suspension
fluid level
For topping up, it is necessary to go
to a CITROËN dealer or a qualified
workshop.
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Changing the coolant
The coolant does not have to be replaced at routine services.
Fluid specification
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 be caught by the fan
blades.
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. When the engine is warm, the temperature of
the coolant is regulated by the fan.
