If it just the Turtle warning light (without the triangle light), you can still drive but your prius will have very low power. The turtle light is just a warning for the battery have very low output due to the very low temperature and/or there are not much power left in the battery. Once your car warm up the turtle light will be gone. (I do have it on my 01 once, I left my car park outside for overnight and it was -23C (-35C with windchill factor). The turtle light stay on after I start my prius and it gone after 10 minute of warm up+driving.)
睡觉了,帮你去普锐斯网站查了,说是traction电池电量低,可能太冷了,不要加速,要平稳行驶,最好能看到灯灭。没啥大问题,电池温度正常了就灭了。
