Datsun Mi-Do Seat Belt Extender
Buckle Up Comfortably in Your Datsun mi-DO
Your mi-DO is a Lada Kalina under the badge, built at Togliatti and sold only in Russia. That matters more than anything else on this page, because it means the mi-DO shares nothing with the Datsun GO despite the shared brand. Read the note below before you order.
The Problem
A hatchback under four meters long has nowhere to put the buckle except low down beside the seat, and in the mi-DO the stalk ends up tucked against the cushion where you cannot see it. In the rear, a short cabin leaves passengers reaching behind the hip for a latch that sits against the bench. Add a heavy winter coat, which these cars spend most of their lives around, and either position becomes a genuine struggle rather than an annoyance.
The Solution
A certified extender brings the connection point back to where your hand already falls. One click into the car's buckle, one click with your factory belt tongue. Nothing is cut, drilled, or modified, which matters on a car whose original parts are no longer easy to come by.

A mi-DO is not a GO, and the difference is total
The revived Datsun brand ran two entirely separate model families. In India and Indonesia the GO and GO+ were built on a Nissan platform closely related to the Micra. In Russia the on-DO and mi-DO were built by AvtoVAZ at Togliatti on Lada underpinnings, with the mi-DO a rebadged and restyled Lada Kalina.
Same badge on the boot, two unrelated cars from different factories on different platforms. So nothing listed for a Datsun GO can be assumed to fit a mi-DO. Order from this page for the Russian-built car and from our GO listing for the Indian or Indonesian one.
mi-DO or on-DO? Count the doors
Datsun sold two cars in Russia and they are easy to mix up. The mi-DO is the five-door hatchback at 3,893mm, based on the Lada Kalina. The on-DO is the four-door saloon at 4,337mm, based on the Lada Granta. Nearly 450mm separates them, and they use different donor cars.
Both share a wheelbase and both were discontinued in December 2020, but they are not interchangeable for belt parts. If yours is the saloon, order from our on-DO listing instead.
Choose Style That Fits Where You Sit
Three styles across our full extender range. Which one you want depends on whether the belt falls short or the buckle is out of reach.
| Style | Best for |
|---|---|
| Regular | Woven webbing in 7 inch or 10 inch matching your factory belt. The usual answer in a mi-DO front or rear, because the seats are modestly shaped and the problem is reach rather than height. |
| Rigid | A solid section in 3, 5 or 7 inch that stands upright and holds the buckle visible above the seat side. Worth it if your hand meets the cushion before it finds the latch, or in heavy winter clothing. |
| Adjustable | Woven webbing with a sliding adjuster covering 9 to 26 inches. Sensible where the same seat is used by people in coats one month and shirtsleeves the next. |

How it works
Nothing is cut, drilled, or modified. The whole thing takes about five seconds and lifts straight back out whenever you want it gone.
Click the extender's tongue into your seat belt receptacle.
Buckle your seat belt into the extender. Takes about five seconds, no tools needed.
To remove it, press the release button just like a normal belt.
Pick Shortest Length That Works
We recommend adding only the minimum length you need to buckle comfortably. More webbing is not safer, it just adds slack.
1.Confirm the model
mi-DO hatchback rather than on-DO saloon, and not a Datsun GO. All three take different parts.
2.Measure in winter clothing
A length chosen in a shirt often fails in a heavy coat. Size for the bulkiest way you actually travel.
3.Need help?
Send your year, seat position and a photo of the buckle, and our team will confirm the fit.
