warning light CITROEN DS4 2023 Owner's Manual

133
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
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 performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
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.
Side wind
F Take into account the increased sensitivity to 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

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
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 and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.

Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams,...).
The engine restarts automatically – START
mode – as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Operation
Going into engine STOP mode
The " ECO" warning lamp comes on in
the instrument panel and the engine
goes into standby automatically:
- with a manual gearbox , at speeds below
12 mph (20 km/h) or when the vehicle is
stationary with the PureTech 130 petrol and
BlueHDi 115 and 120 Diesel versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

W
ith an automatic gearbox , when the
vehicle is stationary and when you press
the brake pedal or put the gear selector in
position N . If your vehicle is fitted with this
system, a time counter calculates
the time spent in STOP mode
during a journey. It resets to
zero every time the ignition is
switched on with the key or the
"START/STOP" button.
STOP mode does not affect the operation
of vehicle systems such as braking, power
steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the key or the "START/STOP" button.
Special cases: STOP mode not
available
STOP mode is not activated when:
- t he vehicle is on a steep slope (uphill or
downhill),
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he vehicle has not exceeded 6 mph (10
km/h) since the last engine start (with the
key or the "START/STOP" button),
-

t
he electric parking brake is applied or being
applied, -

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-
d
emisting is active,
-
c
ertain special conditions (battery charge,
engine temperature, braking assistance,
exterior temperature, etc.) require the
engine to be running to assure control of a
system.
In this case, the " ECO" warning
lamp flashes for a few seconds then
goes off.
This operation is perfectly normal.
Going into engine START mode
The ECO warning lamp goes off and
the engine starts automatically:
-

w

ith a manual gearbox , when you fully
depress the clutch pedal,
-

w

ith an automatic gearbox:
•

g

ear selector in position D or M , when
you release the brake pedal,
•

o

r gear selector in position N and brake
pedal released, when you place the gear
selector in position D or M ,
•
o

r when you engage reverse gear.

The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work on this type of battery must only
be carried out in the dealer network or by
a qualified workshop.
For more information on the 12 V batter y ,
refer to the corresponding section.
Opening the bonnet
Driving on flooded roads
Before driving in a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section. Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode.Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This system only operates when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
Operation
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
-

i
f you are in first gear or neutral with a
manual gearbox, On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamps light up constantly on
the instrument panel.
-
i
f you are in position D or M with an
automatic gearbox.

F When switching on the ignition or with the engine running, press this button to activate
the system; the indicator lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle – car, lorry, cycle
– is detected.
For this, the following conditions must be met:
-

a
ll the vehicles must be moving in the same
direction,
-

t
he speed of your vehicle is between 7 and
87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
-

w
hen a vehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
-

t
he traffic must be flowing normally, No alert will be given in the following situations:
-

i
n the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
-

w
ith vehicles moving in the opposite
direction,
-

d
riving on a winding road or a sharp corner,-

w
hen overtaking or being overtaken by a
very long vehicle (lorry, bus, etc.) which is
also in the rear blind spot and present in the
driver’s front field of vision,
-

w
hen overtaking quickly,
-

i
n very heavy traffic: vehicles detected in
front and behind are confused with a lorry or
a stationary object.
Operation- in the case of an overtaking manoeuvre, if this is prolonged and the vehicle being
overtaken remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer,
a


caravan...
