When trouble arises

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your hybrid transmission.
Contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional 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
entry & start system or the immobilizer system, or if the 12-volt bat-
tery is discharged, the vehicle cannot be towed with the front wheels
on the ground, as the front wheels may be locked. In this case, trans-
port the vehicle with both front wheels or all four wheels lifted.
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 flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.

540 6-1. Specifications
PRIUS +_OM_OM47841E_(EE)
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the proper oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation
by American Petroleum Institute
(API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The International Lubricant Speci-
fication Advisory Committee
(ILSAC) Certification Mark is dis-
played on the front of the con-
tainer.
