Reset the Tire Pressure Warning (TPMS)

After you top up the tires or rotate the wheels on a Mitsubishi Outlander PHEV, the low-pressure warning can stay lit until the monitoring system is re-baselined. There is no button hidden under the dash — it is a few taps on the multi-information display. Here is the sequence.

Mitsubishi Outlander PHEV recommended tire pressures

The Mitsubishi Outlander PHEV runs 2.4 bar (35 psi) front and rear when the tires are cold — the same on both the 16-inch and 18-inch wheels. Raise it to 2.6 bar (38 psi) only for sustained speeds above 160 km/h (99 mph). The exact figures are on the placard in the driver’s door jamb.

Cold pressures from the Outlander PHEV owner’s handbook and the driver’s-door placard — both agree. The PHEV uses the same 2.4 bar (35 psi) front and rear on either wheel size; the 2.6 bar (38 psi) figure applies only above 160 km/h. Check them cold (tires stood 3+ hours or driven under a mile).

Before you reset

The reset stores whatever pressures are in the tires now as the new “correct” baseline, so set them first:

• Inflate all four tires to the pressures on the driver’s door-pillar label, checked cold (before driving, or after the car has stood a few hours).
• Park the car and leave the ignition on (READY not required).
• If you run two sets of sensored wheels (for example winter and summer), have the set you want to keep fitted before you start — see the note below.

Reset the tire-pressure warning

The control you need is the multi-information display switch — a button on the instrument panel, in the lower-dash switch cluster alongside the ASC-OFF and headlamp-levelling switches (not on the steering wheel or stalk).

1. Lightly press the multi-information display switch to bring the display round to the menu screen.
2. Press the switch again to highlight the tire-pressure reset icon (reset of the low-pressure warning threshold).
3. Hold the switch down for about 3 seconds or more. The TPMS “SET” indicator confirms the reset has been stored.
4. Drive off normally. The system now treats your freshly-set pressures as the reference and the warning should clear.

If the “SET” indicator never appears, or the warning will not clear after a correct reset, suspect a flat or unregistered tire sensor rather than the procedure — have the sensors checked rather than repeating the reset.

If you swap between two sets of wheels

The Outlander PHEV can hold two tire-ID sets. Each time you run the reset, it switches the active set (1 → 2 → 1 …), so on a two-set car do the reset until the display shows the set that matches the wheels currently on the car. If only one set of sensor IDs is registered, the reset simply re-baselines and nothing switches.

Frequently Asked Questions

Why does the Outlander PHEV pressure light stay on after I’ve inflated the tires?

The system compares live pressures against a stored baseline; correcting the pressures does not move that baseline on its own. Running the reset above tells the car the current pressures are the new normal, and the warning clears.

Do I need a garage or a tool for this?

No. It is done entirely from the driver’s seat through the multi-information display — no scan tool and no valve-cap gadget.

The tire light is flashing rather than steady — is that different?

Yes. A steady light means low pressure (inflate, then reset); a light that flashes for a while then stays on points to a system fault or a flat sensor battery, which needs checking rather than a reset.

Disclaimer: A tire-pressure reset never replaces a proper pressure check — always set the correct cold pressures first. This is general guidance for the Mitsubishi Outlander PHEV (2014–2021); menus vary by market and model year, so verify against your own handbook. servicereset.net is independent and not affiliated with Mitsubishi Motors.
