2021-2022 Citroen C1 Warning and Indicator Lights User Manual

Introduction

Welcome to the guide on the warning and indicator lights of the 2021-2022 Citroën C1! As modern vehicles become more advanced, dashboard lights play a crucial role in keeping drivers informed about the status of their car. In this guide, we will walk you through the various warning and indicator lights you might encounter while driving your Citroën C1 during the model years 2021 and 2022.

From essential alerts like engine issues and safety features to routine reminders, understanding these lights will help ensure a safe and smooth driving experience. Always consult your vehicle’s manual for specific details and instructions related to these lights. Let’s explore and decode the language of your Citroën C1’s dashboard lights, helping you stay informed on the road ahead.

Warning and indicator lamps

Displayed as symbols, the warning and indicator lamps inform the driver of the occurrence of a malfunction (warning lamps) or of the operating status of a system (operation or deactivation indicator lamps). Certain lamps light up in two ways (fixed or flashing) and/or in several colours.

Associated warnings
The illumination of a lamp may be accompanied by an audible signal and/or a message displayed in a screen.
Relating the type of alert to the operating status of the vehicle allows you to determine whether the situation is normal or whether a fault has occurred: refer to the description of each lamp for further information.
When the ignition is switched on
Certain red or orange warning lamps come on for a few seconds when the ignition is switched on. These warning lamps should go off as soon as the engine is started.
For more information on a system or a function, refer to the corresponding section.

Persistent warning lamp
If a red or orange warning lamp comes on, there may be fault which needs further investigation.
If a lamp remains lit
The references (1), (2) and (3) in the warning and indicator lamp description indicate whether you should contact a qualified professional in addition to the immediate recommended actions.

1. You must stop the vehicle.
2. Stop as soon as it is safe to do so and switch off the ignition.
   Contact a CITROËN dealer or a qualified workshop.
3. Visit a CITROËN dealer or a qualified workshop.

Malfunction of the SCR emissions control system

Malfunction detection

If a malfunction is detected, these warning lamps come on, accompanied by an audible signal and the display of an “Emissions control fault” or “NO START IN” message.
The alert is triggered while driving when the fault is detected for the first time, and thereafter when switching on the ignition for subsequent journeys, for as long as the cause of the fault persists.
If the fault is temporary, the alert disappears during the next journey, after self-diagnostic checks of the SCR emissions control system.

Malfunction confirmed during the permitted driving phase (between 685 miles and 0 miles (1,100 km and 0 km))
If the fault indication is still displayed permanently after 31 miles (50 km) of driving, the fault in the SCR system is confirmed.
The AdBlue warning lamp flashes and a message is displayed (“Emissions control fault: starting prevented in X miles (kms)” or “NO START IN X miles (kms)”), indicating the driving range in miles or kilometres.
While driving, the message is displayed every 30 seconds. The alert is repeated when switching on the ignition.
You can continue driving for up to 685 miles (1,100 km) before the engine starting prevention system is triggered.
Have it checked by a CITROËN dealer or a qualified workshop.

Starting prevented
Every time the ignition is switched on, the message “Emissions control fault: Starting prevented” or “NO START IN” is displayed.

To restart the engine Contact a CITROËN dealer or a qualified workshop.

Power indicator (Electric)

CHARGE
Traction battery charging during deceleration and braking.

ECO
Moderate energy consumption and optimized driving range.

POWER
Energy consumption by the drive train during acceleration.

NEUTRAL
When the ignition is switched on, the vehicle’s electric drive train neither consumes nor generates energy; after sweeping over the indicator, the cursor returns to its “neutral” position: between ECO and CHARGE.

With the ignition off, opening the driver’s door activates the indicator, which moves to the “neutral” position: between ECO and CHARGE.

Charge level indicator (Electric)

The traction battery’s actual charge level and the remaining range are displayed continuously when the vehicle is started.
With the ignition off, opening the driver’s door activates the indicator.

Associated warning lamps
Two successive alert levels indicate that the energy available has dropped to a low level: 1st level: Reserve

The state of charge of the traction battery is low.
Fixed and indicator in the red zone, accompanied by an audible signal.

• View the remaining range on the instrument panel.
• Put the vehicle on charge as soon as possible.

2nd level: Critical
The state of charge of the traction battery is critical.
Fixed, together with the reserve warning lamp, accompanied by an audible signal.

You must put the vehicle on charge. The remaining range is no longer calculated. The drive train power gradually decreases.
The heating and air conditioning are switched off (even if the thermal comfort consumption indicator is not at the “ECO” level).

Thermal comfort consumption indicator (Electric)
(Depending on version)The gauge shows the consumption of the traction battery’s electrical energy by the thermal comfort devices in the passenger compartment. The devices in question are the heating and air conditioning systems.
This equipment can be used:

• If the vehicle is not plugged in, when the READY lamp is lit.
• If the vehicle is plugged in, when the ignition is switched on (“Lounge” mode).

Selecting ECO mode limits the performance of some of this equipment. The thermal comfort consumption indicator then moves into the
“ECO” zone.

To quickly heat or cool the passenger compartment, feel free to temporarily select the maximum heating or cooling setting.
When the heating is on maximum, the gauge on the thermal comfort consumption indicator is in the MAX zone. When the air conditioning is on maximum, it stays in the ECO zone.
Excessive use of thermal comfort equipment, particularly at low speed, can significantly decrease the vehicle’s range.
Remember to optimise equipment settings upon achieving the desired level of comfort, and adjust them if necessary whenever you start the vehicle.
After an extended period without using the heating, you may notice a slight odour during the first few minutes of use.

Lighting dimmer

This control lets you manually adjust the brightness of the instrument panel according to the exterior light level.

With LCD symbols and LCD text/matrix instrument panel

With the lamps on (not in the AUTO position) , press button A to increase the brightness of the lighting, or button B to decrease it.
Release the button when the desired brightness is reached.
