The successor to the Platz, the Belta has increased in size over the previous generation such that its interior volume is comparable to the E120 series Corolla.

For most Asian markets (except Japan), the Belta was sold as the second generation Vios which was built and assembled in China, Malaysia, the Philippines, Thailand and Vietnam.

[16] The Belta received a facelift in August 2008, the exterior was updated with new honeycomb grille, new mirror wings with blinker and redesign hubcaps.

Meanwhile, the G trim has two tone black and beige colors combination plus additional leather wrapped steering wheel, audio control on the steering wheel, start/stop button for automatic transmission model, blue-colored optitron instrument cluster with multi-information display and 60:40 split back seat.

For the exterior, the Limo can be distinguished by the use of 14-inch steel wheels, blinkers on the front fender, the lack of third stop light and unpainted door handles and trunk ornament.

The top of the line G trim added the front and rear fog lamps, auto-leveling HID headlamps, 15-inch alloy wheels, keyless entry button for the automatic transmission model and chrome ornament on the trunk.

It was also fitted with the Super ECT four-speed automatic with the same gear ratios as its predecessor, but with improved programming for the transmission control unit.

It was initially unavailable at the Malaysian Vios launch in October 2007, but was introduced on 1 July 2008, offering a choice of either 5-speed manual or 4-speed automatic transmissions.

[26] The Vios TRD Sportivo was updated on 29 June 2011, featuring a redesigned grille, unique alloy wheels and leather seats.

Another new grade positioned between G and TRD Sportivo called the G Limited was also introduced offering a body kit, 15-inch alloy wheels and leather seats.

[27] The Vios was updated on 21 June 2012 in response to Honda Malaysia's facelift of the fifth generation City, with appearance changes without significant mechanical improvements.

[28] The Malaysian Vios was assembled locally by ASSB, a subsidiary of UMW Toyota, in Shah Alam, Selangor.

The J trim is the lowest version and comes standard with a CD/MP3/WMA player with 4 speakers, keyless entry, ABS/EBD/BA (on front disc brakes only), driver-only SRS airbag and interior fabric with dark grey colour seats.

The G trim adds optitron meters with multi-information display, four-wheel disc brakes, and 60:40 split foldable rear seats.

Optional "Sport" and “Racing” bodykit were offered in late 2008 featuring aftermarket alloy wheels, red stitching on the leather seats and floor mats, gear knob, brushed studded pedals and badging to denote these models in its special run.

These were offered as a cost effective measure for customers who wanted the variant in base form or with extras such as leather seats, piano black interior trims and solar film.

Thailand was the only country that offers all existing grades of the Vios, while export markets are only given a fraction of the Thai range in varying combinations.

The J is the basic trim level of the second generation Vios, offering a CD/MP3/WMA player with four speakers, an optional keyless entry with TVSS, ABS/EBD/BA, 15-inch steel wheels with hubcaps, rear fog lamps and interior fabric with dark grey colour seat.

The E is a mid-level trim featuring a keyless entry with TDS, an option between dark grey or ivory-coloured seat fabrics, optional driver and front passenger SRS airbags, front and rear fog lamps, 15-inch sports alloy wheels and side moulding.

The G trim features an unchangeable 6 speaker CD/MP3/WMA player, leather seating in either dark grey or ivory, driver and front passenger SRS airbags, a multi-functional steering wheel, 15-inch sports alloy wheels front and rear fog lamps, side moulding, a blue "Optitron" panel with a multi-information display and 60:40 fold-down rear seats.

The G Limited trim includes a keyless and smart entry with TDS, a Start/Stop push button, an immobilizer key and a body kit to the exterior.

Toyota Thailand has also exported the Vios to the Middle East, Australia and South Africa, where it was sold as the Yaris.

In the United States, the Yaris sedan is available with modular convenience, power, and all-weather guard packages, contrasting with the global Belta's conventional trim levels.

The Canadian version is being based on the US-market Yaris S with power and all-weather guard packages, but with standard 14-inch (360 mm) wheels.

[32] For the 2009 model year which was a facelift, all Yaris sedans received updated styling with a new grille, alloy designs, interior fabric, standard side curtain airbags and anti-lock brakes.

At the end of 2016, the Australian version Yaris sedan was discontinued due to poor sales with over 27 percent drop.

Standard safety features include airbags, front seatbelt pretensioners, and head restraints for all seating positions.
