If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer 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.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commercial towing service, using a lift-type
truck or flatbed truck.
Use a safety chain system for all to wing, and abide by all state/pro-
vincial and local laws.

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 eyelet 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.
■ Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing. This
may lead to accidents that cause serious injury or even death.
NOTICE
■To prevent causing serious damage to the transmission when towing
using a wheel-lift type truck (vehicl es with an automatic transmission)
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 (vehicles with an automatic transmission)
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 damage to the vehicle when towing using a wheel-lift type
truck (vehicles with a manual transmission)
● Do not tow the vehicle from the rear when the engine switch is in the
“LOCK” position or the key is removed.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
● 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 towing with a sliding-type truck
Do not tow with a sling-type truck, either from the front or rear.

●If non-genuine Toyota wheels are used (Even if you use Toyota
wheels, the tire pressure warning system may not work properly with
some types of tires.)
●If tire chains are used
■If the tire pressure warning light frequently comes on after blinking
for 1 minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned to the “ON” position, have it
checked by your Toyota dealer.
■Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features →P. 368) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger when seat belts are not fastened.
CAUTION
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■
If the tire pressure warning light comes on (vehicles with a tire
pressure warning system)
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 comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, change it with the spare tire and have the flat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.

CAUTION
■Replacing a flat tire
●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 extremely 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 wheel nuts that have been specifi- cally 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
your Toyota dealer.
• When installing the wheel nuts, be sure to install them with the tapered ends facing inward. ( →P. 267)
■When stowing the flat tire
●Make sure the rear seats are in their original position.
● Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out in
case of the sudden braking or an accident, resulting in death or serious
injury.

CAUTION
■If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Never attempt to remove the key, as doing so will lock the steering wheel.
