Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

NOTICE
To prevent causing serious damage to the transmission when towing using a
wheel-lift type truck
Never tow this vehicle from the front with the rear wheels on the ground.
To prevent damage to the vehicle when towing using a wheel-lift type truck
Do not tow the vehicle from the rear with the power switch off. The steer-
ing lock mechanism is not strong enough to hold the front wheels straight.
When raising the vehicle from the rear, ensure adequate ground clearance
for towing at the opposite end of the raised vehicle. Without adequate
clearance, the vehicle could be damaged while being towed from the rear.
To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
