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.

Starting / Switching oﬀ the

engine with the key

Nose weight

► Distribute 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.

Key ignition switch

Brakes

Braking distances are increased when towing a

trailer. To avoid overheating of the brakes, the

use of engine braking is recommended.

Tyres

► Check the tyre pressures of the towing

vehicle and of the trailer, observing the

recommended pressures.

Side wind

Bear in mind the increased susceptibility to the

wind that the vehicle will have.

Lighting

It has 3 positions:

– 1. Stop: inserting and removing the key,

steering column locked.

► Check the electrical signalling on the trailer

and the headlamp beam height of your vehicle.

Anti-theft protection

If a genuine CITROËN towing device is

used, the rear parking sensors will be

deactivated automatically to avoid the audible

signal.

– 2. Ignition: steering column unlocked, ignition

on, Diesel preheating, engine running.

– 3. Starting.

Electronic immobiliser

The key contains an electronic chip which has a

special code. When the ignition is switched on,

this code must be recognised in order for starting

to be possible.

Avoid attaching heavy objects to the key

or the remote control. It would weigh

down on its shaft in the ignition switch and

could cause a malfunction.

When driving

Cooling

This electronic engine immobiliser locks the

engine management system a moment after

the ignition is switched oﬀ, and prevents

unauthorised engine starting.

In the event of a fault, you are informed

by illumination of this warning lamp, an

audible signal and a message in the screen.

In this case, your vehicle will not start; contact

a CITROËN dealer or a qualiﬁed workshop as

soon as possible.

Towing a trailer uphill increases the temperature

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.

Ignition on position

It allows the use of the vehicle's electric

equipment or portable devices to be charged.

Once the state of charge of the battery drops to

the reserve level, the system switches to energy

economy mode : the power supply is cut oﬀ

► Reduce speed and lower the engine speed,

so as to limit the heating-up.

Driving

To facilitate unlocking of the steering

column, it is recommended that the

wheels be returned to the straight ahead

position before switching oﬀ the engine.

automatically to preserve the remaining battery

charge.

Wait until this warning lamp goes oﬀ in the

instrument panel, then operate the starter

motor by turning the key to position 3 without

pressing the accelerator pedal, until the engine

starts. Once the engine starts, release the key.

Starting the engine

With the parking brake applied:

► With a manual gearbox, place the gear lever

in neutral then fully depress the clutch pedal.

► With an automatic gearbox, place the gear

selector in mode N or P then fully depress the

brake pedal.

Never switch oﬀ the ignition before the

complete immobilisation of the vehicle.

With the engine oﬀ, the braking and steering

assistance systems are also cut oﬀ - risk of

loss of control of the vehicle!

In wintry conditions, the warning lamp

may stay on for a longer period. When

the engine is hot, the warning lamp does not

come on.

► Insert the key into the ignition switch; the

system recognises the code.

► Unlock the steering column by simultaneously

turning the steering wheel and the key.

again. If the engine does not start after a few

attempts, do not keep trying - risk of

damaging the starter motor and the engine.

Contact a CITROËN dealer or a qualiﬁed

workshop.

In certain cases, you may have to apply

signiﬁcant force to move the steering

wheel (wheels on full lock, for example).

Energy economy mode

After the engine has stopped (position 1. Stop),

for a maximum combined duration of about thirty

minutes, you can still use functions such as the

audio and telematics system, courtesy lamps,

windscreen wipers, dipped beam headlamps,

etc.

► With a petrol engine, operate the starter

motor by turning the key to position 3 without

pressing the accelerator pedal, until the engine

starts. Once the engine starts, release the key.

In mild conditions, do not leave the

engine at idle to warm up but move oﬀ

straight away and drive at moderate speed.

With petrol engines, after a cold start,

preheating the catalytic converter can

cause noticeable engine vibrations for

anything up to 2 minutes while stationary with

the engine running (accelerated idle speed).

Switching oﬀ the engine

► Immobilise the vehicle.

► With the engine at idle, turn the key to

position 1.

For more information on Energy

economy mode, refer to the

corresponding section.

► With a Diesel engine, turn the key to position

2, ignition on, to operate the engine preheating

system.

► Remove the key from the ignition switch.

► To lock the steering column, turn the steering

wheel until it locks.
