7487-2. Steps to take in an emergency
ES350 300h_OM_OM33A01U_(U)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving ma neuvers which place excessive stress on
the emergency towing eyelet and the cable or chain. Always be cautious of the
surroundings and other vehicles while towing.
●Gasoline vehicles: If the engine is not running, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
Hybrid vehicles: 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 eyelet to the vehicle
Make sure that towing eyel et is installed securely.
If not securely installed, towing eyelet 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 rear with the front wheels on the ground.
■To prevent damage to the vehicle when towing using a wheel-lift type truck
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 body damage when to wing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
