This is the maintenance schedule and service intervals for the Toyota GR Yaris, the high-performance hot hatch from Toyota that’s much more GR than it is Yaris.
The Toyota GR Yaris is a compact sports car powered by a 1.6-litre (1618 cc) turbo three-cylinder engine that makes a peak of 192 kW / 257 hp of power at 6500 rpm and 360 Nm / 266 ft-lb of torque — making it the most powerful three-cylinder engine on the market. Peak torque is available from 3000 to 4600 rpm, giving it a nice mid-range plateau.
With a kerb weight of just 1280 kg, the power-to-weight ratio is a whopping 200.8 bhp / tonne. The GR Yaris rated for 0-100 km/h (0-60 mph) of 5.5 seconds.
Along with the Toyota GR Supra, the GR Yaris gets the GR racing moniker (GR is short for Gazoo Racing), as a nod to the fact that this is a homologation special of a race-oriented vehicle.
Power goes to the ground via a six-speed manual sports transmission and a unique “GR-Four” drive system that has three driving modes, allowing you to control the power distribution between front and rear. Awesome!

Overall Maintenance Schedule Table for your Toyota GR Yaris
Below is the overall maintenance schedule table for your GR Yaris. It’s the same information as in the service booklet.
The service intervals are a guide or minimum requirement. You may need to service your vehicle more often if you drive it in rough conditions, e.g. on dirt, dusty, or muddy roads, in snow or conditions with corrosive substances on the roads, in coastal areas, with heavy loads in tow, or in a lot of start-stop traffic.
Needless to say, if you track your GR Yaris, you should also follow a more stringent service schedule.
- There is no “break-in” service. The oil and filter need only be changed at the first service.
- Follow the earlier of the time or distance service interval in the below schedule.
- The below maintenance schedule is cropped at 36 months / 60000 km for ease of reading. Longer-term service items (e.g. replacing coolant) are mentioned in a table below.
The basic service interval of the Toyota GR Yaris is every 6 months or every 10000 km. At these services you should inspect everything and change the oil and filter.
- I = Inspect and correct or adjust as necessary
- R = Replace
- C = Clean
- T = Tighten

About the Toyota GR Yaris
The Toyota GR Yaris a high-performance sports car developed by the Gazoo Racing World Rally Team based on the Toyota Yaris, an otherwise sedate and everyday car that is good for runs about town. But despite sharing a brand name, the GR Yaris is almost an entirely different vehicle.
Almost everything is different about the Toyota GR Yaris, so it’s worth examining what makes it special in detail.
Firstly, there’s the engine. It’s the highest power three cylinder engine in production. The engine is a 1618cc G16E-GTS turbocharged inline three-cylinder engine that makes a peak of 192 kW / 257 hp of power at 6500 rpm and 360 Nm / 266 ft-lb of torque. Peak torque is available from 3000 to 4600 rpm, giving it a nice mid-range, helped by dual VVT-i.
Power goes to the ground via a six-speed “intelligent manual transmission” and a GR-Four permanent four wheel drive system.
Toyota made the GR Yaris specifically because Toyota CEO Akio Toyoda feels it necessary to represent the company at the World Rally Championships (WRC). So Toyota built the Yaris in rally form, and knew it had to produce at least 2500 units of the GR Yaris to meet homologation requirements.
The GR-Four system is quite unique in itself.
The GR-Four system is a permanent electronically-controlled all-wheel drive system. In addition to being permanent AWD, Toyota gives you three driving modes — Normal, Track, and Sport — which give different amounts of balance between front and rear power. In fact, some people modify the GR Yaris, overriding this system to give full power to the rear. (But it slides even in the other modes.)
The power split is 50:50 in Track for maximum balance, 30:70 in sport so you can slide it out at will, and 60:40 in normal, suitable for day-to-day traction requirements.
The AWD system is simple in design and lightweight — lighter than alternative twin-coupling or centre differential systems. Both the front and rear have Torsen limited slip differentials.
Suspension on the GR Yaris is via a new MacPherson strut design. And brakes are similar in size to those on the GR Supra — in fact, the front brake discs are larger, with twin 356 discs up front with 4-pot monoblock calipers, and 297 mm discs at the rear with 2-pot monoblock calipers.
The GR Yaris weighs a modest 1280 kg, giving it a healthy 200 bhp / metric tonne ratio (never mind the combining of imperial and metric units).
In summary, the Toyota GR Yaris is a thoroughbred high-performance Toyota sports car, built in-house, which is a contrast with the Toyota GR Supra, for example, which shares many components with the 2018+ BMW Z4.
Where to get a Manual for the Toyota GR Yaris
The above information was obtained from a combination of the warranty service booklet for the GR Yaris, the owner’s manual, and literature searches on supplier websites.
