NOTICE
■To prevent causing serious damage to the automatic transmission
Never tow this vehicle from the front with the rear wheels on the ground.
■To prevent damaging the vehicle
●Do not tow the vehicle with the “ENGINE START STOP” switch is OFF.
The steering lock mechanism is not strong enough to hold the front wheel
straight.

opposite end of the raised vehicle. Without adequate clearance, the vehicle
could be damaged while being towed.
