For more information on snow chains,
contact a CITROËN dealer or a
qualified workshop.

Snow chains

In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when
braking.

Advice on installation

If you have to fit the chains during a

journey, stop the vehicle on a flat surface
on the side of the road.

Apply the parking brake and position any

wheel chocks to prevent movement of
your vehicle.

Fit the chains following the instructions

provided by the manufacturer.

Move off gently and drive for a few

moments, without exceeding 30 mph
(50 km/h).

Stop your vehicle and check that the snow

chains are correctly tightened.

The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.

Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.

Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road surface. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.

Use only chains designed for fitment to the type
of road wheels on your vehicle:

Original equipment

tyre size

Maximum link size

215/70 R16

12 mm

225/55 R18

It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.

Towing a trailer, a caravan, etc.

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 following the manufacturer's
instructions.

Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer.

Driving with a trailer subjects the towing vehicle
to more significant stress and its driver must be
particularly careful.
For more advice on driving when towing, refer
to the corresponding section.
For more information on Petrol weights or
Diesel weights

and in particular the towed

loads which apply to your vehicle, refer to the
corresponding section.
Take care to comply with the gross train
weights indicated on the registration certificate
or in the technical data for your vehicle.

178

Advice on driving when towing

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 towing load must
be reduced by 10 % of the GTW and so on for
every 1 000 metres of altitude.
For more information on Petrol weights or
Diesel weights

and in particular the towed

loads which apply to your vehicle, refer to the
corresponding section.

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.
F

To lower the engine speed, reduce your

speed.

The maximum towed load on a long slope
depends on the gradient and the exterior
temperature.
In all cases, pay attention to the coolant
temperature.

If this message is displayed, stop your

vehicle as soon as it is safe to do so.

Braking

Towing a trailer increases the braking distance.
To limit heat build-up in the brakes, use of the
engine brake is recommended.

Tyres

Check the tyre pressures of the towing

vehicle and of the trailer, observing the
recommended pressures.

Lighting

Check the lighting and signalling on the

trailer and the adjustment of the vehicle's
headlamps.

For more information on Headlamp
adjustment

, refer to the corresponding

section.

If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.

The rear parking sensors will be
deactivated automatically when a
genuine CITROËN towbar is used.

Fitting roof bars

The transverse roof bars are fitted to the longitudinal bars at the 8 fixing points masked by covers.
Using a small screwdriver, remove the 8 covers on the inner faces of the longitudinal bars.

The transverse bars are fitted directly to the roof of the vehicle, at the 4 anchorage points masked
by covers.
Slide the covers towards the front of the vehicle to remove them.
Retain the protective covers.
After removing the roof bars, the protective covers should be refitted:
F

insert the fixing tongues into the apertures then slide the covers towards the rear of the vehicle.

The body sill finishers should not be
used as a step when fitting roof bars.

Use accessories recommended by
CITROËN and follow the accessory
manufacturer's fitting instructions.
Maximum authorised weight on the roof
bars, for a loading height not exceeding
40 cm (except bicycle carriers): 80 kg.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the condition of
the road, to avoid damaging the roof
bars and the fixings on the roof.
Please refer to national legislation to
comply with the regulations regarding
the transportation of objects which are
longer than the vehicle.

For reasons of safety and to avoid damaging the roof, it is essential to use transverse bars that are
approved for your vehicle.

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).

Oil level

The check of the level is done with
the dipstick, located under the
bonnet. Refer to the description of
your engine compartment for the
position of the dipstick.

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.

Oil specification

The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.

Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

Dipstick

There are two marks on the dipstick:

= maximum

If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B

= minimum

Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.

This check will only 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 services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
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.

184

Practical information

C4-Aircross_en_Chap07_info-pratiques_ed01-2016

Coolant level

The coolant level should be between
the two marks.

When the engine is warm, the temperature of
the coolant is regulated by the fan.
As the cooling system is pressurised when the
engine is warm, 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 specification

The coolant must conform to the
manufacturer's recommendations.

The brake fluid level should be close
to the "MAX" mark. If it is not, check
the brake pad wear.

Brake fluid level

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.

The cooling fan may start after switching
off the engine: take care with articles and
clothing that might become caught by the
fan blades.

To ensure that this measurement is reliable, the
vehicle must be parked on level ground with the
engine cold.

185

Practical information

C4-Aircross_en_Chap07_info-pratiques_ed01-2016

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.

Particle filter (Diesel)

The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp, accompanied by a message in
the instrument panel screen.

As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine, the minimum speed is 37 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels

and the Diesel additive level in

particular, refer to the corresponding
section.

On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is perfectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.

Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.

Brake pads

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.

Brake disc wear

Parking brake

If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.

Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.

Checking this system must be done by a
CITROËN dealer or a qualified workshop.

Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
