When trouble arises
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelets. This should only be attempted on hard surfaced roads
for at most 50 miles (80 km) at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
For vehicles with an automatic transmission, only the front towing
eyelets may be used.
Take out the towing eyelet. ( →P. 313)
Remove the eyelet cover by
turning.
Insert the towing eyelet into the
hole and tighten partially by
hand.

Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light co mes on even after tire inflation pres-

WARNING
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoi d unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immedi- ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area
around the brakes will be extremel y hot. Touching these areas with
hands, feet or other body parts while changing a tire, etc., may
result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft·lbf
(103 N·m, 10.5 kgf·m) as soon as possible after changing wheels.
• When installing a tire, only use w heel nuts that have been specifi-
cally designed for that wheel.
• If there are any cracks or deforma tions in the bolt screws, nut threads
or bolt holes of the w heel, have the vehicle inspected by your Toyota
dealer.
• When installing the wheel nuts, be sure to install them with the
tapered ends facing inward. ( →P. 266)
