■ When stopped/during start off The gasoline engine stops* when the vehicle is stopped. Duringstart off, the electric motor (traction motor) drives the vehicle. Atslow speeds or when traveling down a gentle slope, the engineis stopped* and the electric motor (traction motor) is used.

When shift position is in N, the hybrid battery (traction battery)will not be charged. Thus, shift to P when the vehicle is stopped.In addition, when driving in heavy traffic, use D or B.

*: However, when the hybrid battery (traction battery) need to becharged or while the engine is being warmed up, the gasolineengine may not stop automatically. (→P. 31)

■ During normal drivingThe gasoline engine is predominantly used. The electric motor(traction motor) charges the hybrid battery (traction battery) asnecessary.

■ When accelerating sharplyWhen the accelerator pedal is depressed heavily, the power ofthe hybrid battery (traction battery) is added to that of the gaso-line engine via the electric motor (traction motor).

■ When braking (regenerative braking)The electric motor (traction motor) charges the hybrid battery(traction battery).

Vehicle proximity notification system

When driving with the gasoline engine stopped, a sound, whichchanges in accordance with the driving speed, will be played in orderto warn people nearby of the vehicle’s approach. The sound will stopwhen the vehicle speed exceeds approximately 15 mph (25 km/h).

■Regenerative brakingIn the following situations, kinetic energy is converted to electric energy anddeceleration force can be obtained in conjunction with the recharging of thehybrid battery (traction battery).

●The accelerator pedal is released while driving with the shift position in Dor B.

●The brake pedal is depressed while driving with the shift position in D orB.

■Conditions in which the gasoline engine may not stopThe gasoline engine starts and stops automatically. However, it may not stopautomatically in the following conditions*:

●During gasoline engine warm-up

●When the temperature of the hybrid battery (traction battery) is high orlow

●During hybrid battery (traction battery) charging

●When the heater is switched on

*: Depending on the circumstances, the gasoline engine may also not stopautomatically in situations other than those above.

■Charging the hybrid battery (traction battery)●As the gasoline engine charges the hybrid battery (traction battery), the

battery does not need to be charged from an outside source. However, ifthe vehicle is left parked for a long time the hybrid battery (traction bat-tery) will slowly discharge. For this reason, be sure to drive the vehicle atleast once every few months for at least 30 minutes or 10 miles (16 km). If the hybrid battery (traction battery) becomes fully discharged and youare unable to jump-start the vehicle with the 12-volt battery, contact yourToyota dealer.

● If the shift position is in N, the hybrid battery (traction battery) will not becharged. Always shift the shift position in P when the vehicle is stopped.When driving in heavy traffic, operate the vehicle with the shift position inD or B to avoid discharging the hybrid battery (traction battery).

■Charging the 12-volt battery→P. 482

■After the 12-volt battery has discharged or has been changed orremoved The gasoline engine may not stop even if the vehicle is running on the hybridbattery (traction battery). If this continues for a few days, contact your Toyotadealer.

■Sounds and vibrations specific to a hybrid vehicleThere may be no engine sounds or vibration even though the vehicle is ableto move. For safety, apply the parking brake and make sure to shift the shiftposition to P when parked.

The following sounds or vibrations may occur when the hybrid system isoperating and are not a malfunction:

●The brake system operation sound heard from the front of the vehiclewhen the driver’s door is opened.

●Motor sounds may be heard from the engine compartment.

●Sounds may be heard from the hybrid battery (traction battery) when thehybrid system starts or stops.

●Sounds may be heard from the transmission when the gasoline enginestarts or stops, when driving at low speeds, or during idling.

●Engine sounds may be heard when accelerating sharply.

●Sounds may be heard due to regenerative braking when the brake pedalis depressed and accelerator is loosened.

●Other sounds, such as motors and mechanical noises, may be heardfrom the brake system when the brake pedal is depressed.

●Vibration may be felt when the gasoline engine starts or stops.

●Cooling fan sounds may be heard from the air intake vent. (→P. 35)

●The operation sound of the air conditioning system (air conditioning com-pressor, blower motor).

Hybrid battery (traction battery) air vent

There is an air intake vent underthe rear seat for the purpose ofcooling the hybrid battery (trac-tion battery). If the vent becomeblocked, the hybrid battery (trac-tion battery) may overheat, lead-ing to a reduction in hybridbattery (traction battery) output.

Emergency shut off system

When a certain level of impact is detected by the impact sensor, theemergency shut off system blocks off the high voltage current andstops the fuel pump to minimize the risk of electrocution and fuelleakage. If the emergency shut off system activates, your vehicle willnot restart. To restart the hybrid system, contact your Toyota dealer.

■ If a warning light comes on, a warning message is displayed or the 12-volt battery is disconnectedThe hybrid system may not start. In that case, try to start the system again. Ifthe “READY” indicator does not come on, contact your Toyota dealer.

■Running out of fuelWhen the vehicle has run out of fuel and the hybrid system cannot bestarted, refuel the vehicle with at least enough gasoline to make the low fuellevel warning light (→P. 449) go off. If there is only a small amount of fuel,the hybrid system may not be able to start. (The minimum amount of fuel toadd to make the low fuel level warning light go out is about 1.8 gal. [7 L,1.5 Imp.gal.], when the vehicle is on a level surface. This value may varywhen the vehicle is on a slope.)

■Electromagnetic waves●High voltage parts and cables on the hybrid vehicles incorporate electro-

magnetic shielding, and therefore emit approximately the same amountof electromagnetic waves as conventional gasoline powered vehicles orhome electronic appliances.

●Your vehicle may cause sound interference in some third party-producedradio parts.

■Hybrid battery (traction battery)The hybrid battery (traction battery) has a limited service life. The lifespan ofthe hybrid battery (traction battery) can change in accordance with drivingstyle and driving conditions.

CAUTION

■Road accident cautionsIf your vehicle is involved in an accident, observe the following precautionsto reduce the risk of death or serious injury:

●Stop the vehicle in a safe place to prevent subsequent accidents. While depressing the brake pedal, apply the parking brake and shift theshift position to P to stop the hybrid system. Then, slowly release thebrake pedal.

●Do not touch the high voltage parts, cables and connectors.

● If electric wires are exposed inside or outside your vehicle, an electricshock may occur. Never touch exposed electric wires.

● If a fluid leak occurs, do not touch the fluid as it may be strong alkalineelectrolyte from the hybrid battery (traction battery). If it comes into contactwith your skin or eyes, wash it off immediately with a large amount of wateror, if possible, boric acid solution. Seek immediate medical attention.

● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.Never use a fire extinguisher that is not meant for electric fires. Using evena small amount of water may be dangerous.

● If your vehicle needs to be towed, do so with front wheels raised. If thewheels connected to the electric motor (traction motor) are on the groundwhen towing, the motor may continue to generate electricity. This maycause an electricity leakage leading to a fire. (→P. 435)

●Carefully inspect the ground under the vehicle. If you find that liquid hasleaked onto the ground, the fuel system may have been damaged. Leavethe vehicle as soon as possible.

■Hybrid battery (traction battery)Your vehicle contains a sealed nickel-metal hydride battery. If disposed ofimproperly, it is hazardous to the environment and there is a risk of severeburns and electrical shock that may result in death or serious injury.

Hybrid vehicle driving tips

For economical and ecological driving, pay attention to the followingpoints:

■ Using Eco drive modeWhen using Eco drive mode, the torque corresponding to the accelera-tor pedal depression amount can be generated more smoothly than it isin normal conditions. In addition, the operation of the air conditioningsystem (heating/cooling) will be minimized, improving the fuel econ-omy. (→P. 185)

■ Use of Hybrid System IndicatorEco-friendly driving is possible by keeping the indicate of Hybrid Sys-tem Indicator within Eco area or Charge area. (→P. 201)

■ When braking the vehicleMake sure to operate the brakes gently and in good time. A greateramount of electrical energy can be retained when slowing down.

■ DelaysRepeated acceleration and deceleration, as well as long waits at trafficlights, will lead to bad fuel consumption. Check traffic reports beforeleaving and avoid delays as much as possible. When encountering adelay, gently release the brake pedal to allow the vehicle to move for-ward slightly while avoiding overuse of the accelerator pedal. Doing socan help control excessive gasoline consumption.

■ Highway drivingControl your speed and keep at a constant speed. Also, before stop-ping at a toll booth or similar, allow plenty of time to release the acceler-ator and gently apply the brakes. A greater amount of electrical energycan be retained when slowing down.

■ Air conditioning on/off

Switch the air conditioning ( ) to off when it is not needed. Doing

so can help control excessive gasoline consumption.

In summer: In high temperatures, use the recirculated air mode. Doingso will help to reduce the burden on the air conditioner and reduce fuelconsumption as well.

In winter: Because the gasoline engine will not automatically cut outuntil the gasoline engine and the interior of the vehicle are warm, it willconsume fuel. Also, fuel consumption can be improved by avoidingoveruse of the heater.

■ Checking tire inflation pressureMake sure to check the tire inflation pressure frequently. Improper tireinflation pressure can cause poor fuel consumption.Also, as snow tires can cause large amounts of friction, their use on dryroads can lead to poor fuel consumption. Use a tire that is appropriatefor the season.

■ LuggageCarrying heavy luggage can lead to poor fuel consumption. Avoid car-rying unnecessary luggage. Installing a large roof rack can also causepoor fuel consumption.

■ Warming up before drivingSince the gasoline engine starts up and cuts out automatically whencold, warming up the engine is unnecessary. Moreover, frequently driv-ing short distances will cause the engine to repeatedly warm up, whichcan lead to poor fuel consumption.
