Fleetola can engage the immobiliser relay on a tracked vehicle from wherever you are. It is the most serious action in the product, so it is wrapped in deliberate checks: only the owner can send it, a typed reason is required, and the button refuses until an immobiliser relay is confirmed. Tracking is an optional paid module, switched on per account - contact us to add it to your plan. Without it none of this appears.
What Engage relay actually does
The tracker opens its immobiliser relay. The relay engages once the vehicle is doing under 20 km/h - a moving car is not stopped dead, it cuts out as it slows - and it will not restart until you release the relay. The renter is not notified.
Immobilise a vehicle
- Open Tracking and click the vehicle.
- On the Commands tab, switch on Engage relay.
- Type why. The reason is recorded against your account in the vehicle's command log and cannot be edited - an immobilisation with no justification on record is indefensible later.
- Confirm. The line under the switch shows Relay engaged with the time, and the badge turns red to Engaged only when the tracker itself confirms it - never off the button press.
- Switching it back releases the relay. No reason is asked for - releasing is the safe direction. It is logged all the same.
Where to find it: Tracking → a vehicle → Commands
Owner-only, both ways
Only the account owner can engage or release the relay. Stopping a car is too serious to hand to every login, and the release is held just as tightly: if any team member could release it, one could quietly undo your immobilisation of a stolen vehicle.
Why it says Not fitted
A tracker alone cannot stop a car - an immobiliser relay must be physically wired into the vehicle. A tracker without one still accepts the command, reports success, and the car keeps driving. Nothing in the device reports whether that wiring exists, so Fleetola refuses to send the command until you confirm the relay yourself on the vehicle's Device tab. Your confirmation is the record - give it only when a relay is actually installed.

The car is offline - is it immobilised?
No. A command sent to an offline tracker is queued: it runs when the tracker reconnects, and until then the vehicle is not immobilised. Fleetola tells you which happened - delivered to a connected device, or queued - and an offline car is the normal state of a car being recovered, so read the answer before you act on it.
Tip: Queued is not immobilised, and even delivered is not stopped. The only proof the relay engaged is the red Engaged badge, reported back by the tracker itself.
When to reach for it
Recovering a stolen or unreturned vehicle, and contracts that have stopped paying. Nothing else - it strands whoever is driving. A moving car is safe: the relay waits until the car slows under 20 km/h.
