The Toyota Yaris Cross has 397 L of boot behind the rear seats on the 2WD and 320 L on the AWD-i, which loses about 77 L to its rear motor and electronics. On the AWD-i, choose a slim kit. The two-piece boot floor also slides to make a level load bay, so check where a kit sits once the floor has been moved.
Frequently asked questions
Is an emergency kit legally required in a Toyota Yaris Cross in the UK?
Nothing is legally required for a UK car outside commercial and PSV rules - unlike France, Spain and Italy which mandate a warning triangle and hi-vis vest. That said, if you break down on a motorway hard shoulder, you need a hi-vis vest to leave the car safely, so kit yourself even if the law does not.
What fits in the Yaris Cross’s boot alongside luggage?
The Yaris Cross lists 397 L behind rear seats (2WD); 320 L on AWD-i; ~1097 L seats folded. A compact roll-bag emergency kit sits under the boot floor cover on most trims, or in a side cubby without eating into daily luggage space. Full winter kits (blanket, shovel, jump pack, warning triangle) need a soft holdall - hard cases are wasted space here.
What UK-specific extras belong in the kit?
Ice scraper and de-icer for October to March, a foil emergency blanket for stranded motorway waits, and a warm woollen blanket if the Yaris Cross is used in Scotland or upland Wales. A small folding shovel earns its place for snow country. A litre of drinking water and a couple of energy bars round it out.
One thing many buyers miss
Portable lithium jump packs are useful across petrol, diesel, hybrid and even EVs (for the 12V battery), but they self-discharge - roughly five to fifteen per cent per month. A jump pack left in the boot of the Yaris Cross for a year is usually flat when you finally need it. Set a phone reminder to top it up every three to six months, or the kit stops being a kit.
How to check before ordering
- Confirm the jump pack’s peak amps rating suits the Yaris Cross’s engine or 12V system (petrol under 3 L: 400 A is plenty; V6 diesel Ranger: 800 A up).
- Look for cables with insulated clamps and a case that survives a UK winter boot temperature swing.
- Add a hi-vis vest per occupant, not just one for the driver - passengers need to be seen too if you exit on the hard shoulder.
