Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, ti res or the tire pressure warning
valves and transmitters, contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional as the tire pressure
warning valves and transmitters may be damaged if not handled correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than those
specified.
The cap may become stuck.
■ To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional or other qualified service shop as soon as possible.
Make sure to replace the tire pres sure warning valve and transmitter when
replacing the tire. ( →P. 332)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

WARNING
■ Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated tires
● Air leaking from between tire and wheel
● Wheel deformation and/or tire damage
● Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■ When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, tire pressure warning valves and transmitters must be
installed. ( →P. 332)
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

WARNING
■ When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non-genuine wheels.
●Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
outward can cause the wheel to break
and eventually cause the wheel to come
off while driving, which could lead to an
accident resulting in death or serious
injury.Tapered

emergency
Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort
required to slow the vehicle.
Shift the shift position to N.
XIf the shift position is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the hybrid system.
XIf the shift position cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehicle
speed as much as possible.
To stop the hybrid system,
press and hold the power
switch for 2 consecutive sec-
onds or more, or press it briefly
3 times or more in succession.
Stop the vehicle in a safe place by the road.

WARNING
■ If the hybrid system has to be turned off while driving
Power assist for the steering wheel will be lost, making the steering wheel
heavier to turn. Decelerate as much as possible before turning off the hybrid
system.

If your vehicle needs to be towed
In the following situations, it is not possible to be towed by another
vehicle using cables or chains, as the front wheels may be locked due
to the parking lock. Contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional or commercial
towing service.
●There is a malfunction in the shift control system. ( →P. 378, 390)
● There is a malfunction in the immobilizer system. ( →P. 9 1 )
● There is a malfunction in the smart entry & start system. ( →P. 437)
● The 12-volt battery is discharged. ( →P. 439)
The following may indicate a problem with your hybrid transmission.
Contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional or commercial towing service
before towing.
● The hybrid system warning light turns on or the hybrid system
warning message is displayed on the multi-information display and
the vehicle does not move.
● The vehicle makes an abnormal sound.
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 commercial towing
service, using a lift-type truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/
provincial and local laws.

If your Toyota is transported by a
flat bed truck, it should be tied
down at the locations shown in the
illustration.
If you use cables or chains to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie
downs or the vehicle may be dam-
aged.
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.
