If  your vehicle needs 
to be towed
If towing is necessary, we 
recommend having your 
vehicle towed by your Toy-
ota dealer or commercial 
towing service, using a 
wheel-lift type truck or flat-
bed truck.
Use a safety chain system 
for all towing, and abide by 
all state/provincial and local 
laws.
WARNING
Observe the following precau-
tions.
Failure to do so may result in 
death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle 
with the front wh eels raised or 
with all four wheels raised off the 
ground. If the vehicle is towed 
with the front wh eels contacting 
the ground, the drivetrain and 
related parts may be damaged.
■While towing
●When towing using cables or 
chains, avoid sudden starts, etc. 
which place excessive stress on 
the towing eyelets, cables or 
chains. The towing eyelets, 
cables or chains may become 
damaged, broken debris may hit 
people, and cause serious dam-
age.
●Do not turn the engine switch 
off.
There is a possibility that the 
steering wheel is locked and 
cannot be operated.
■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 damage to the 
vehicle when t owing using a 
wheel-lift type truck
●Do not tow the vehicle from the 
rear when the engine switch is 
off.
●When raising the vehicle, 
ensure adequate ground clear-
ance for towing at the opposite 
end of the raised vehicle. With-
out adequate clearance, the 
vehicle could be damaged while 
being towed.
■To prevent damage to the 
vehicle when towing with a 
sling-type truck
Do not tow with a sling-type truck, 
either from the front or rear.
