2020 CITROEN RELAY check engine

65
Driving
6Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.
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.
In case of towing
Driving with a trailer places greater
demands 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 density
of the air decreases with altitude and the
performance of the engine reduces.
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
► 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.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► 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 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.
► Reduce 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.

66
Driving
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.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system. It
activates automatically when the key is removed
from the ignition.
When the ignition switch is turned on, a dialogue
is set up between the key and the electronic
immobiliser.
This warning lamp goes off after the key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.
Carefully note the key number. In case of
loss, the intervention of a CITROËN
dealer will be faster and more efficient if you
provide this number and the confidential card.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even in your
pocket, may cause the doors to be unlocked
accidentally.
The simultaneous use of other high-frequency
devices (mobile phones, home alarms, etc.),
may temporarily disturb the operation of the
remote control.
Except for reinitialisation, the remote control
cannot operate while the key is in the ignition
switch, even when the ignition is off.
Driving with the doors locked could make
it more difficult for the emergency
services to enter the vehicle in an emergency.
As a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.
When purchasing a second-hand
vehicle:
– check that you are in possession of the
confidential card,
– have the keys memorised by a CITROËN
dealer, to be sure that the keys in your
possession are the only ones that allow the
vehicle to be started.
Confidential card

It is given to you upon delivery of your vehicle
with the duplicate key.
It contains the identification code required for
any intervention by a CITROËN dealer on the
electronic engine immobiliser system. This code
is hidden by a film, which is to be removed only
when necessary.
Keep your card in a safe place, never inside the
vehicle.
When undertaking a long trip or journey
however, it is advisable to take this card with you
along with your personal papers.

Starting the engine
► With the parking brake applied and the
gearbox in neutral, turn the key to the MAR
position.
► Wait until this warning lamp goes out,
then operate the starter (AV V position)
until the engine starts.
The period of illumination of the warning lamp
depends on the climatic conditions.
When the engine is hot, the warning lamp lights
up for a few moments; you can start the engine
immediately.
► When the engine starts, release the key.
Immobiliser warning lamp
If this warning lamp lights up, change key
and have the faulty key checked by a CITROËN
dealer.
Switching off the engine
► Immobilise the vehicle.
► Move the key back to the STOP position.
In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited to
low or minus temperatures.
Battery standby system
If your vehicle is to be out of use for an extended
period of time, such as during winter storage for
example, it is strongly recommended to put the battery in standby mode in order to protect it and
optimise its life.


To put the battery in standby mode:
► Switch the engine off ( STOP position).


► Press the red button, then turn the key to the
BATT position.
The battery goes into standby mode
approximately 7 minutes later.
This time is necessary to:
– allow the user to leave the vehicle and lock the
doors using the remote control.
– ensure that all vehicle electrical systems are
deactivated.

68
Driving
When the battery is in standby mode,
access to the vehicle is only possible by
unlocking the mechanical lock on the driver's
side door.
After a battery standby, the information (time, date, radio stations, etc.) is
memorised.
To remove the battery from standby mode:
► Turn the key to the MAR - ON position.
► Start the vehicle normally ( AV V position).
Parking brake
Application
► Apply the parking brake to immobilise the
vehicle.
► Check that the parking brake is correctly
applied before leaving the vehicle.
Apply the parking brake only when the
vehicle is stationary.
When parking on a slope, turn your
wheels towards the kerb and pull the
parking brake lever up.
There is no advantage in engaging a gear
after parking the vehicle, particularly if the
vehicle is loaded.
In the event of a failure of the
hydraulic braking system
While driving , to avoid any accidental
movement of the vehicle, use the parking
brake while depressing the brake pedal.
In this exceptional circumstance, it is
advisable to pull the parking brake up gently
so as not to block the rear wheels - risk of
skidding!
Release

► Pull the lever up gently and press the button
to release the parking brake.
When the vehicle is being driven, this
warning lamp coming on indicates that
the parking brake is still applied or has not been
fully released.
Manual gearbox
To change gear easily, always fully depress the
clutch pedal.
To prevent the mat from becoming caught under
the pedal:
– ensure that the mat is positioned correctly,
– never fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear the
internal components of the gearbox over time.
Engaging reverse gear

► Lift the ring under the knob to engage reverse
gear.
Never engage it until the vehicle has
come to a complete stop.
The movement must be done slowly to reduce
the noise when engaging reverse gear.
If fitted to the vehicle, the parking
sensors are activated when reverse gear
is engaged; an audible signal sounds.
For more information on the Parking
sensors, refer to the corresponding section.
Gear shift indicator
Depending on version or engine, this system
reduces fuel consumption by recommending a
higher gear change.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
The system cannot be deactivated.
Operation
The information appears in the instrument panel screen in the form of the SHIFT
indicator, accompanied by an upward arrow to
signal to the driver that they can change up.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never recommends engaging first
gear or reverse, or changing down.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,

70
Driving
Never leave the vehicle without first
switching the ignition off with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not activated when:
– the system is initialising,
– the driver's door is open,
– the driver's seat belt is not fastened,
– the air conditioning is on,
– the rear screen demisting is on,
– the windscreen wipers are on fast wipe,
– the reverse gear is engaged for the parking
manoeuvre,
– some special conditions (battery charge,
engine temperature, particle filter regeneration,
braking assistance, exterior temperature, etc.)
where the engine is needed to assure control of
a system.
– during intensive use of Stop & Start, it may
be deactivated to conserve starting ability;
go to a CITROËN dealer to have the function
reactivated.
This indicator lamp in the instrument panel flashes for a few seconds, then
goes off.
This operation is perfectly normal.
Going into engine START
mode
With a gear engaged, the automatic restarting of
the engine is only possible by fully depressing
the clutch pedal.
This indicator lamp goes off and the engine restarts.
If, after an automatic restart in START mode, the
driver does not perform any action on the vehicle
within 3 minutes, the system stops the engine
permanently. The engine can only be restarted
with the ignition key.
Special cases: START mode
activated automatically
The START mode may be invoked automatically
in the following circumstances:
– the vehicle is free-wheeling on a gradient,
– the windscreen wipers are on fast wipe,
– the air conditioning is on,
– the engine has been stopped for around 3
minutes with Stop & Start,
– some special conditions (battery charge,
engine temperature, braking assistance, air
conditioning setting, etc.) where the engine is
needed for control of the system or vehicle.
In this case, a message appears in the
instrument panel screen, accompanied by
this indicator lamp, which flashes for a few
seconds, then goes off.
This operation is perfectly normal.
While in STOP mode with a manual
gearbox, if a gear is engaged without
fully depressing the clutch pedal, restarting
may not take place.
An indicator lamp and/or message is
displayed in the instrument panel asking
you to fully depress the clutch pedal to allow
restarting.
With the engine stopped in STOP mode,
if the driver unfastens their seat belt and
opens a front door, the engine can only be
restarted using the ignition key. There is an
audible signal, accompanied by flashing of this
indicator lamp, and the display of a message.
Malfunction
In the event of a malfunction, the Stop &
Start is deactivated and this warning lamp
comes on, accompanied by a message on the
instrument panel display.
Have the system checked by a CITROËN dealer
or a qualified workshop.
In the event of a malfunction in STOP mode, the
engine can be restarted by fully depressing the
clutch pedal or putting the gear lever in neutral.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,

Driving
6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking brake
manually then ensure that the parking brake
indicator lamp is on.
Hill start assist is deactivated in the following
situations:
– when the clutch pedal is released,
– when the parking brake is applied,
– when the engine is switched off,
– if the engine stalls.
Malfunction
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system checked by a
CITROËN dealer or a qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
The under-inflation detection system does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding,
– lengthens braking distances,
– causes premature wear of the tyres,
– increases fuel consumption.

beyond the point of resistance, to exceed the
programmed limit speed.


The speed limiter is deactivated temporarily and
the programmed speed flashes.
To return to the speed limiter function, reduce
your speed below the programmed speed.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the programmed speed.
Switching the function off
► Place the ring in the central position O or
switch the ignition off to stop the system.
The last programmed speed remains in the
memory.
Malfunction

The programmed speed is cleared, then
replaced by dashes.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Fixed speed limiter

If your vehicle is equipped with it, the speed of
your vehicle can be limited in a fixed way to 56
mph (90 km/h) or 62 mph (100 km/h).
A label located in the passenger compartment
indicates this maximum speed.
The fixed speed limiter is not a cruise control
type function. It cannot be activated or
deactivated by the driver during the trip.
