1. An off-road vehicle comprising:
a travel mechanism that includes a travel motor, wheels including a front wheel and a rear wheel, and a power transmission mechanism transmitting rotation from the travel motor to the wheels, the power transmission mechanism including a continuously variable transmission (CVT) belt and a transfer box switchable between a front and rear wheel drive mode in which rotation of the travel motor is transmitted to both the front wheel and the rear wheel and a rear wheel drive mode in which rotation of the travel motor is transmitted to the rear wheel and is not transmitted to the front wheel;
a sensor that detects a travel condition caused by the travel mechanism; and
processing circuitry that
determines whether the travel condition caused by the travel mechanism has become a predetermined belt check request condition based on an output of the sensor, and
performs, when determining that the travel condition has become the belt check request condition, travel function limitation processing of limiting a travel function performed by the travel mechanism more than that before determination,
wherein the processing circuitry determines a cumulative travel index value as a travel condition based on an output of the sensor, the cumulative travel index value being either one of travel distance, travel time, or an index value that increases or decreases with travel distance or travel time; and
wherein the travel function limitation processing comprises processing of suppressing an output of the travel motor or limiting speed; and
wherein the speed limitation processing is configured such that limiting speed is only performed in the front and rear wheel drive mode, and is not performed in the rear wheel drive mode.
