Checking Engine Oil Condition

 

Hybrid Prius C

The PRIUS c 5-door hatchback joins the PRIUS, PRIUS V, CAMRY Hybrid and HIGHLANDER Hybrid as a hybrid model for Toyota. 

Hybrid Synergy Drive means that the vehicle contains a gasoline engine and an electric motor for power. The two hybrid power sources are stored on board the vehicle: 

1. Gasoline stored in the fuel tank for the gasoline engine.

2. Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack for the electric motor. 

The result of combining these two power sources is improved fuel economy and reduced emissions. The gasoline engine also powers an electric generator to charge the battery pack; unlike a pure all electric vehicle, the PRIUS c never needs to be charged from an external electric power source. 

Depending on the driving conditions one or both sources are used to power the vehicle. The following illustration demonstrates how the PRIUS c operates in various driving modes.

(1) During light acceleration at low speeds, the vehicle is powered by the electric motor. The gasoline engine is shut off. 

(2) During normal driving, the vehicle is powered mainly by the gasoline engine. The gasoline engine also powers the generator to charge the battery pack and to drive the electric motor.

(3) During full acceleration, such as climbing a hill, both the gasoline engine and the electric motor power the vehicle. 

(4) During deceleration, such as when braking, the vehicle regenerates kinetic energy from the front wheels to produce electricity that charges the battery pack.

(5) While the vehicle is stopped, the gasoline engine and electric motor are off, however the vehicle remains on and operational.

Hybrid Battery System Precautions

PRECAUTIONS FOR INSPECTING HYBRID BATTERY SYSTEM

(a) Take safety precautions before inspection of high-voltage system, to to keep yourself safe from electrical shocks. Safety precautions are; wearing insulated gloves and removing service plug grip. When service plug grip is removed, put it in your pocket or away to prevent other technicians from from reconnecting it while you are busy in servicing of high-voltage. 

NOTICE:

When the power switch is turned ON (READY) after the service plug grip is removed, a malfunction could arise. So refrain from turning power switch ON (READY), unless advised by repair manual.

(b) Wait for at least 5 minutes after the service plug is disconnected, before touching any high-voltage connectors or terminals.

HINT:

For discharging high-voltage condenser inside the inverter, 5 minutes are at least necessary.

(c) Always wear protective goggles while checking inside the HV battery, as liquid leakage might occur.

(d) Before handling any of the orange-colored wires in high-voltage system, always wear insulated gloves, the power switch turned OFF, the negative terminal of auxiliary  battery be disconnected, 

(e) The power switch should be turned OFF first before carrying out a resistance check.

(f) The power switch should be turned OFF first before any connector is disconnected or reconnected.

(g) For installation of the service plug grip, it is necessary to flip and lock down the lever. The interlock switch is turned ON once the lever is locked down right in place. Always make sure to securely lock it. In case if you leave it unlocked, a DTC relating to interlock switch system is will be shown  be the vehicle sysem

API Engine Oil Change Guidelines

American Petroleum Institute (API) guidelines to help you get more from your motor (engine) oil.

 

• Always refer to your car owner’s manual for type of oil to use.
• Always follow manufacturer’s motor oil change recommendations.
• Always use only the recommended API category:“S” for gasoline engines; i.e. SG, SH, SJ, SL, SM, SN, SP, & “C” for diesel engines; CH-4, CI-4, CJ-4.
• Always select the proper SAE oil viscosity grade.
• If you want to mix different brands of oil, use the same viscosity grade and API service category to properly maintain performance.
• Always properly dispose of used engine oil.
• Always Look for the API Certification marks every time you buy engine oil.
• Always ask your vendor for API-licensed oil whenever you have your oil changed.
