Driving -> Gear efficiency indicator for Your Citroen C3 Aircross SUV First Generation (2017-2023)

Driving  
As a safety precaution and to facilitate  
starting the engine:  
– Always select neutral.  
– Press the clutch pedal.  
Operation  
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 is only active when:  
Gear efficiency indicator  
– The vehicle is completely stationary, with  
your foot on the brake pedal.  
– Certain slope conditions are met.  
– The driver’s door is closed.  
This system helps reduce fuel consumption by  
recommending the most appropriate gear.  
Facing uphill, with the vehicle stationary, the  
vehicle is held for a short time when the driver  
releases the brake pedal:  
– If first gear or neutral is engaged on a manual  
gearbox.  
Operation  
Do not leave the vehicle while it is  
being held temporarily by hill start  
assist.  
If someone needs to get out of the vehicle  
with the engine running, apply the parking  
brake manually. Then check that the parking  
brake indicator lamp is on fixed in the  
instrument panel.  
The system advises to change gear.  
The information appears in the  
instrument panel in the form of an  
ascending or descending arrow.  
The number displayed is the current gear.  
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 hill start assist function cannot be  
deactivated. However, use of the  
parking brake to immobilise the vehicle  
interrupts its operation.  
Facing downhill, with the vehicle stationary  
and reverse gear engaged, the vehicle is held  
for a short time when the driver releases the  
brake pedal.  
This function cannot be deactivated.  
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 suggests:  
– engaging first gear;  
Malfunction  
These warning lamps come on in

workshop to have the system checked.
