CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and skin cancer, so care
should be taken to avoid prolonged and repeated contact. To remove used
engine oil from your skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call your Toyota dealer, service station or auto parts store for
information concerning recycling or disposal.
●Do not leave used engine oil within the reach of children.
NOTICE
■To p r e v e n t s e r i o u s e n g i n e d a m a g e
Check the oil level on a regular basis.
■When replacing the engine oil

■Driving on rough roads
Ta k e p a r t i c u l a r c a r e w h e n d r i v i n g on roads with loose surfaces or pot-
holes.
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.

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your hybrid transmission.
Contact your Toyota dealer before towing.
●The hybrid system is operating but the vehicle will not move.
●The vehicle makes an abnormal sound.
If there is a malfunction in the P position control system, the smart
key system or the immobilizer system, or if the 12-volt battery is dis-
charged, the vehicle cannot be towed with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the
vehicle with both front wheels or all four wheels lifted.
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 flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.

5-2. Steps to take in an emergency
PRIUS PHV_OM_OM47856U_(U)
NOTICE
■When performing an emergency repair
●A tire should only be repaired with the emergency tire puncture repair
kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergency repair with the repair kit.
●The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction
may occur.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle
use. Do not connect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate.
Ta k e c a r e n o t t o a l l o w gasoline to contact it.
●Place the repair kit in a storage to prevent it from being exposed to dirt
or water.
●Store the re pa ir kit in the luggage compartment ou t of reach of chil-
dren.
●Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to impacts. This may cause a malfunction.

Uniform Tire Quality Grading
This information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Yo u r To y o t a d e a l e r w i l l h e l p a n s wer any questions you may have as
you read this information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■Tr e a d w e a r
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use. Performance may differ significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
