In case of towing
Driving with a trailer places greater
d emands 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
decreased air density at altitude reduces
engine performance.
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
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.
F

D
istribute 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.
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 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
t emperature 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.
F

R
educe 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.
Brakes
Braking distances are increased when towing
a trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.

spills on engine components (risk of fire).
Do not star t the engine if the level is:
-

A
bove mark A
, then contact a CITROËN
dealer or a qualified workshop.
-
B
elow mark B
, then top up the engine oil
immediately.
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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health,
and may be very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers
reser ved for this purpose at a
CITROËN
dealer or a
qualified workshop.
Engine oil
The level is checked either using the
oil level indicator in the instrument
panel when the ignition is switched
on, for vehicles equipped with an
electric gauge, or using the dipstick.
The vehicle must be parked on a level sur face,
w ith the engine stopped for more than 30 minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). It is recommended
that you check the level, and top up if
necessary, every 3,000
miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close
to the " MAX" mark. If not, check the
brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Engine coolant
Check the engine coolant level
regularly.
It is normal to top up this fluid
between two services. The check and top-up must only be done with
the engine cold.
A low level presents a
risk of serious damage
to the engine.
The level of this fluid should be close to the
" MAX " mark but should never exceed it.
If the level is close to or below the " MIN" mark,
it is essential to top up.
When the engine is hot, the temperature of this
fluid 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 the risk of scalding if you need to top
up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow
the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

could be caught in the blades of the
fan!Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
Filling with pure water is prohibited
under all circumstances (risk of freezing,
limestone deposits, jets, etc.).

Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a
test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a
CITROËN
dealer or a
qualified workshop.
Weights and towed loads
The weights and towed loads relating to your
vehicle are given in the registration document,
as well as in sales brochures.
These values are also given on the
manufacturer's plate or label.
For more information, contact a CITROËN
dealer or a
qualified workshop. The GTW (Gross Train Weight) and towed load
values indicated are valid up to a
maximum
altitude of 1,000 metres. The towed load value
must be reduced by 10% for each additional
1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
When exterior temperatures are high,
the vehicle per formance may be limited
in order to protect the engine. When the
exterior temperature is higher than 37°C,
limit the towed weight.
Towing using a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
When using a
vehicle to tow, never exceed
a
speed of 62 mph (100 km/h) (obser ve
the local legislation in force).
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1
to 2 minutes after the vehicle
comes to a
stop, to facilitate its cooling.
