If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional before towing.
The engine is running, but the vehicle will not move.
The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only be attempted on hard surfaced roads
for short distances at low speeds.
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
eyelet may be used.
If towing is necessary, we recommend having your vehicle towed by
any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional or a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be
in good condition. (P. 357)
If they are damaged, use a towing dolly or flat bed truck.

unavoidable, avoid towing a vehicle that is heavier than your vehicle. Also,
do not pull out a vehicle that has fallen into a ditch.
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.
If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.

CAUTION
Replacing a flat tire
Do not touch the disc wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or
other body parts while changing a tire, etc. may result in burns.
Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
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 120 N
•m (12.2
kgf
•m, 89 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped
professional.
• When installing the wheel nuts, be sure to install them with the tapered
ends facing inward. (P. 317)
NOTICE
Do not drive the vehicle with a flat tire.
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Stowing the jack
When stowing the jack in the jack holder, make sure that the part that the
jack handle attaches to is pointing towards the inside of the trunk. Failure to
do so may damage the vehicle body.

can be repaired temporarily using the emergency tire puncture repair

once to temporarily repair one tire without removing the nail or
screw from the tire.) Depending on the damage, this kit cannot be
used to repair the tire. (P. 382)
After temporarily repairing the tire with the kit, have the tire repaired
or replaced by any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional. Repairs conducted using
the emergency tire puncture repair kit are only a temporary measure.
Have the tire repaired and replaced as soon as possible.

Set the parking brake.
Shift the shift lever to P (vehicles with an automatic transmis-
sion) or N (vehicles with a manual transmission).
