WARNING
■When to disable the pre-crash safety system 
In the following situations, disable the system, as it may not operate prop- 
erly, possibly leading to an accident resulting in death or serious injury: 
● When the vehicle is being towed 
● When your vehicle is towing another vehicle 
● When transporting the vehicle via truck, boat, train or similar means of 
transportation 
● When the vehicle is raised on a lift with the hybrid system on and the tires 
are allowed to rotate freely 
● When inspecting the vehicle using a drum tester such as a chassis 
dynamometer or speedometer tester , or when using an on vehicle wheel 
balancer 
● When a strong impact is applied to the front bumper or front grille, due to 
an accident or other reasons 
● If the vehicle cannot be driven in a stable manner, such as when the vehi- 
cle has been in an accident or is malfunctioning 
● When the vehicle is driven in a sporty manner or off-road 
● When the tires are not properly inflated 
● When the tires are very worn 
● When tires of a size other than specified are installed 
● When tire chains are installed 
● When a compact spare tire or an emergency tire puncture repair kit is used 
● If equipment (snow plow, etc.) that may obstruct the radar sensor or cam- 
era sensor is temporarily installed to the vehicle

Driving
PRIUS +_OM_OM47D30E_(EE)
WARNING
■Before using LDA system 
Do not rely solely upon the LDA system. The LDA system does not auto- 
matically drive the vehicle or reduce the amount of attention that must be 
paid to the area in front of the vehicle. The driver must always assume full 
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the 
vehicle. Also, the driver must take adequate breaks when fatigued, such as 
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention 
may lead to an accident, resulting in death or serious injury. 
■ To avoid operating LDA system by mistake 
When not using the LDA system, use the LDA switch to turn the system off. 
■ Situations unsuitable for LDA system 
Do not use the LDA system in the following situations. 
The system may not operate properly  and lead to an accident, resulting in 
death or serious injury. 
● A compact spare tire (if equipped), tire chains, etc., are equipped. 
● When the tires have been excessively worn, or when the tire inflation pres- 
sure is low. 
● Tires which differ by structure, manufacturer, brand or tread pattern are 
used. 
● Objects or patterns that could be mistaken for white (yellow) lines are 
present on the side of the road (guardrails, curbs, reflective poles etc.). 
● Vehicle is driven on a snow-covered road. 
● White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc. 
● Asphalt repair marks, white (yellow) line marks, etc., are present due to 
road repair. 
● Vehicle is driven in a temporary lane or restricted lane due to construction 
work. 
● Vehicle is driven on a road surface which is slippery due to rainy weather, 
fallen snow, freezing, etc. 
● Vehicle is driven in traffic lanes other than on highways and freeways. 
● Vehicle is driven in a construction zone. 

3946-3. Do-it-yourself maintenance
PRIUS +_OM_OM47D30E_(EE)
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 450)
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. (P. 395)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating front and rear tires which have different tire infla-
tion pressures
●When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

4547-2. Steps to take in an emergency
PRIUS +_OM_OM47D30E_(EE)
WARNING
■If both the ABS and the brake system warning lights remain on 
Stop your vehicle in a safe place immediately and contact any authorized 
Toyota retailer or Toyota authorized r epairer, or any reliable repairer. The 
vehicle will become extremely unstable during braking, and the ABS system 
may fail, which could cause an accident resulting in death or serious injury. 
■ When the electric power steering system warning light comes on 
The steering wheel may become extremely heavy. 
When steering wheel operations are heavier than usual, grip the steering 
wheel firmly and operate it using more force than usual. 
■ If the tire pressure warning light comes on 
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 infla- 
tion pressure immediately.  
● Vehicles with spare tire: If the tire pressure warning light comes on even 
after tire inflation pressure 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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. 
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn- 
ing light comes on even after tire inflat ion pressure adjustment, it is proba- 
ble that you have a flat tire. Check the tire s. If a tire is flat, repair the flat tire 
by using emergency tire puncture repair kit. 
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you 
could lose control of the steering wheel or the brakes. 
■ If a blowout or sudden air leakage should occur 
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly 
Do not install tires with different specif ications or makers, as the tire pres- 
sure warning system may not operate properly. 

4787-2. Steps to take in an emergency
PRIUS +_OM_OM47D30E_(EE)
If you have a flat tire (vehicles with spare  
tire)
● Stop the vehicle in a safe place on a hard, flat surface. 
● Set the parking brake. 
● Shift the shift position to P. 
● Stop the hybrid system. 
● Turn on the emergency flashers. (P. 434)
Your vehicle is equipped with a spare tire. The flat tire can be 
replaced with the spare tire. 
For details about tires:  P.  3 9 3
WARNING
■If you have 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, which could result in an accident.

Remove any dirt or foreign mat- 
ter from the wheel contact sur- 
face.
If foreign matter is on the wheel 
contact surface, the wheel nuts 
may loosen while the vehicle is in
motion, causing the tire to come 
off.
Install the spare tire and loosely tighten each wheel nut by hand by 
approximately the same amount. 
When replacing an aluminum 
wheel with a steel wheel 
(including a compact spare 
tire), tighten the wheel nuts until 
the tapered portion comes into 
loose contact with the disc 
wheel seat. 
When replacing an aluminum 
wheel with an aluminum wheel, 
turn the wheel nuts until the 
washers come into contact with 
the disc wheel.
