Adjust Tyre Pressure
Dacia 'Adjust Tyre Pressure' in car: under-inflation detected
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
On a Dacia Sandero with tyre pressure monitoring, 'Adjust Tyre Pressure' means the system detected low pressure in a tyre (wheel shown in yellow). Set all four tyres when cold to the door label pressures, then reset the system.
Safety first
Stop and check this first
- Dacia says that for a tyre pressure fault the warning light requires you to stop immediately as soon as traffic conditions allow. Fully laden or towing, limit speed to 100 km/h and increase tyre pressure by 0.2 bar: risk of tyre blowout.
- The system is a driving aid and does not replace your vigilance. Check tyre pressures, including the emergency spare wheel, at least once a month and before any long journey.
Safe checks you can perform
- Measure and set pressures when cold
- Reset the tyre pressure reference
- Read the wheel colour and the message

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Tyre repair or replacement
What they doIf the tyre is punctured, the workshop repairs it or replaces it with a tyre of the same make, size, type and profile on the same axle, as Dacia requires.
They must show youthe damage found on the tyre and the final pressure of all four wheels.
In writingwhether the tyre was repaired or replaced, its size and make, the pressures set and whether the system was reset.
Tyre pressure sensor check
What they doIf 'Check Tyre Pressure Sensors' appears or the warning stays after adjusting and resetting, the approved dealer checks the sensors and reinitialises the system if wheels were swapped.
They must show youthe pressure each sensor reads and the fault memory readout (stored and pending codes).
In writingany sensor replaced, the codes read and whether codes were cleared before or after the repair.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Measure and set pressures when cold
- Who:
- you, with a pressure gauge, with the car stopped away from traffic.
- How:
- with cold tyres, set all four to the pressures on the label on the edge of the driver's door, for current usage (empty, loaded, motorway). If you cannot check them cold, Dacia says to increase the values by 0.2 to 0.3 bar. Never deflate a hot tyre.
- Result that matters:
- all four tyres at the label pressure.
- If one tyre was low:
- after adjusting it, reset the tyre pressure reference value.
- If it loses pressure again quickly:
- it may be punctured; have it repaired or replaced.
- Evidence to keep:
- photo of the door label and a note of the measured pressures.
Measure with the car parked in a safe place away from traffic. Never deflate a hot tyre.

Reset the tyre pressure reference
- Who:
- you, with the ignition on and the vehicle stopped.
- How:
- tap switch 5 until you reach the 'Vehicle' tab, press 2 or 3 to reach the 'Tyre Pressure' page and press and hold control 4 for about 3 seconds. The tyre warning light flashes and 'Learning Tyre Pressures' then 'Tyre detection in progress' appear. Always do it after checking all four pressures cold.
- Result that matters:
- after several minutes of driving, the pressures of all four wheels are displayed.
- If all four values appear:
- the reset is complete and successful.
- If 'Check Tyre Pressure Sensors' appears or a wheel is no longer shown:
- a sensor is missing or faulty, contact an approved dealer.
- Evidence to keep:
- photo of the display with the four pressures.

Read the wheel colour and the message
- Who:
- you, with the car stopped in a safe place.
- How:
- look at the instrument panel: a yellow wheel with 'Adjust Tyre Pressure' means under-inflation; a red wheel with 'Puncture' means a punctured or severely underinflated tyre. Stop as soon as traffic allows, as Dacia instructs.
- Result that matters:
- knowing whether adjusting the pressure is enough or the wheel must be changed.
- If 'Puncture' is shown:
- adjust the pressures cold and reset if the tyre was only deflated; replace the tyre (or have it replaced) if it is punctured.
- If you use the inflation kit:
- because the valves are specially designed, use only equipment approved by the brand's network.
- Evidence to keep:
- photo of the panel showing the wheel colour.

What it means
In the Dacia Sandero 3 user manual (edition 04/11/2024 to 14/10/2025), 'Adjust Tyre Pressure' appears with the tyre warning light on (not flashing) and the wheel and its pressure shown in yellow: tyre under-inflation has been detected. If the wheel is red with 'Puncture', the tyre is punctured or severely underinflated. Dacia says that for a tyre pressure fault the warning light requires you to stop as soon as traffic allows. Other models or versions without sensors work differently. The message alone does not prove that a part is faulty.

Symptoms and causes
Probable causes · in order
- Tyre pressure too lowCommon
Each wheel except the emergency spare has a sensor in the inflation valve that measures pressure; the message appears when it detects insufficient pressure in a tyre.
Evidence: Dacia Sandero 3 user manual (04/11/2024 to 14/10/2025): Tyre pressure monitoring system
- Puncture or deflated tyrePossible
Dacia lists deflated or punctured tyres among tyre pressure faults; with a large loss the wheel turns red with the 'Puncture' message.
Evidence: Dacia Sandero 3 user manual (04/11/2024 to 14/10/2025): Tyre pressure monitoring system
- Pressures not matched to the loadPossible
Tyre pressures must match current usage (empty, carrying a load, motorway); fully laden or towing, Dacia says to increase pressure by 0.2 bar.
