CAUTION
■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.
● Do not turn the “POWER” switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
● 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. This
may lead to accidents that cause serious injury or even death.
NOTICE
■To prevent damaging the vehicle
When raising the vehicle, 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.
■ To prevent causing serious damage to the hybrid 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 body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■ To prevent causing serious damage to the hybrid transmission in
emergency towing
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the hybrid transmission.
