Vehicle Care

Jump Starting

{ WARNING

Personal injury, death, or damage to the vehicle can result if you try jump starting or using a battery charger on the high voltage hybrid battery. Use only the 12-volt battery for jump starting and charging.

For more information about the vehicle battery, see Battery on page 10‑12. If the vehicle's 12‐volt battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Use the following steps to do it safely.

{ WARNING

Batteries can hurt you. They can be dangerous because:

. They contain acid that can

burn you.

. They contain gas that can

explode or ignite.

. They contain enough electricity to burn you.

If you do not follow these steps exactly, some or all of these things can hurt you.

Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty. Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle. 1. Check the other vehicle. It must

have a 12‐volt battery with a negative ground system.

Notice: Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. If the other vehicle's system is not a 12-volt system with a negative ground, both vehicles can be damaged.

2. Get the vehicles close enough

so the jumper cables can reach, but be sure the vehicles are not touching each other. It could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put the automatic transmission in P (Park) or a manual transmission in N (Neutral) before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear, not in N (Neutral).

Notice: If you leave the radio or other accessories on during the jump starting procedure, they could be damaged. The repairs would not be covered by the warranty. Always turn off the radio and other accessories when jump starting the vehicle. 3. Turn off the ignition on both

vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or the accessory power outlets. Turn off the radio and all the lamps that are not needed. This avoids sparks and helps save both batteries. It could save the radio!

4. Open the hood on the other

vehicle and locate the positive (+) and negative (−) terminal locations on that vehicle.

Vehicle Care

10-33

Your vehicle has a remote positive (+) and a remote negative (−) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery.

If the vehicle has a remote positive (+), it is located under a red plastic cover at the positive battery post. To uncover the remote positive (+) terminal, open the red plastic cover.

5. The remote negative (−) is a

solid engine ground.

{ WARNING

An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

{ WARNING

Using an open flame near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right

WARNING (Continued)

amount of fluid is there. If it is low, add water to take care of that first. If you do not, explosive gas could be present. Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

{ WARNING

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

6. Check that the jumper cables do

not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too.

Before you connect the cables, here are some basic things you should know. Positive (+) goes to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (−) will go to a heavy, unpainted metal engine part or a solid engine ground. Do not connect positive (+) to negative (−) or you will get a short that would damage the battery and maybe other parts too. Do not connect the negative (−) cable to the negative (−) terminal on the dead battery because this can cause sparks.

7. Connect the red positive (+)

cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) if the vehicle has one.

8. Do not let the other end touch

metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) if the vehicle has one.

9. Now connect the black

negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part or to the remote negative (−) terminal on the vehicle with the dead battery.

10. Connect the other end of the

negative (−) cable to the remote negative (−) terminal, on the vehicle with the dead battery.

11. Now start the vehicle with the

good battery and run the engine for a while.

12. Try to start the vehicle that had

the dead battery. If it will not start after a few tries, it probably needs service.

Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by the vehicle warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.

4. Disconnect the red positive (+)

cable from the other vehicle.

5. Return the remote positive (+)

terminal cover to its original position.

Towing

Recreational Vehicle Towing Recreational vehicle towing means towing the vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as dinghy towing and dolly towing. Dinghy towing is towing the vehicle with all four wheels on the ground. Dolly towing is towing the vehicle with two wheels on the ground and two wheels up on a device known as a dolly.

Here are some important things to consider before recreational vehicle towing: . What is the towing capacity

of the towing vehicle? Be sure to read the tow vehicle manufacturer's recommendations.

. What is the distance that will be travelled? Some vehicles have restrictions on how far and how long they can tow. Is the proper towing equipment going to be used? See your dealer or trailering professional for additional advice and equipment recommendations. Is the vehicle ready to be towed? Just as preparing the vehicle for a long trip, make sure the vehicle is prepared to be towed.

In Brief

A chime will sound if the driver door is opened while in Auto Stop as a reminder that the ignition switch is not in the LOCK/OFF position. Always turn the ignition switch to LOCK/OFF and remove the key from the ignition switch when exiting the vehicle. Auto Start The vehicle also has an Auto Start feature. The engine will remain off while in Auto Stop mode until vehicle conditions require the engine to run. The near-instant starting of the engine from Auto Stop mode is called Auto Start. EV Mode The vehicle also has an EV mode which uses only the electric motor to move the vehicle. With light acceleration, the vehicle will drive in EV mode. EV mode is unavailable when the vehicle is out of fuel. For more information on Auto Stop, Auto Start, and EV Mode, see Starting the Vehicle on page 9‑2.

Regenerative Braking Regenerative braking enables the electric drive motor to operate as a generator when coasting or braking. Energy from the moving vehicle recharges the hybrid battery. The hydraulic disc brakes work with the regenerative braking to insure effective braking. The braking system is computer controlled and blends the regenerative braking with the conventional hydraulic disc brakes to meet any requirements for deceleration. Because the controller applies the hydraulic brakes through its high pressure accumulator, you may occasionally hear the motor driven pump when it recharges the system. This is normal. In the event of a controller problem, the brake pedal may be harder to push and the stopping distance may be longer. See Regenerative Braking on page 9‑15.

Battery This vehicle has a standard 12-volt battery and a high voltage hybrid battery. When a new standard 12-volt battery is needed, see your dealer for one that has the replacement number shown on the original battery's label. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the hybrid battery. See your dealer if the hybrid battery needs service. See Battery on page 10‑12.

Service Never try to do your own service on hybrid components. You can be injured and the vehicle can be damaged if you try to do your own service work. Service and repair of these hybrid components should only be performed by a trained service technician with the proper knowledge and tools. See Doing Your Own Service Work on page 10‑2.

Power Outlets

Power Outlet Alternating Current The vehicle may have a power outlet that can be used to plug in electrical equipment that uses a maximum limit of 150 watts.

An indicator light on the outlet comes on when in use. The ignition must be in ON/RUN and equipment requiring less than 150 watts is plugged into the outlet, and no system fault is detected. If equipment is connected using more than 150 watts, or a system fault is detected, a protection circuit shuts off the power supply and the indicator light turns off. To reset the circuit, unplug the item and plug it back in or turn the Retained Accessory Power (RAP) off and then back on. The power restarts when equipment using 150 watts or less is plugged into the outlet and a system fault is not detected.

The power outlet is not designed for and may not work properly if the following are plugged in: . Equipment with high initial

peak wattage such as: compressor-driven refrigerators and electric power tools.

. Other equipment requiring an extremely stable power supply such as: microcomputer-controlled electric blankets, touch sensor lamps, etc.

See High Voltage Devices and Wiring on page 10‑14.

The power outlet is located in the rear cargo area on the driver side.

When the ignition is on, the fuel gauge shows approximately how much fuel is left in the tank. The gauge will first indicate E (empty) before it is out of fuel, but the vehicle should be refueled as soon as possible. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on.

Listed are four situations that may occur with the fuel gauge, none of these indicate a problem: . At the gas station, the fuel pump shuts off before the gauge reads F (full). It takes a little more or less fuel to fill up than the fuel gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank.

The gauge moves a little while turning a corner or speeding up. The gauge does not go back to E (empty) when the ignition is turned off.

A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the oil as soon as possible.

{ WARNING

Do not keep driving if the oil pressure is low. The engine can become so hot that it catches fire. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.

Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule for changing engine oil.

AUTO STOP When the engine goes into Automatic Engine Stop, the oil pressure gauge drops to zero when the tachometer is at the AUTO STOP position. This is normal and oil pressure returns to the normal operating range once the engine starts. See Starting the Vehicle on page 9‑2 for more information. AUTO STOP displays in the Driver Information Center (DIC) when the vehicle speed is zero. See Driver Information Center (DIC) on page 5‑11 for more information.

English

The oil pressure gauge shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure should be 200 to 550 kPa (29 to 80 psi). In certain situations, such as long extended idles on hot days, it could read as low as 105 kPa (15 psi) and still be considered normal.

Engine Coolant Temperature Gauge

Charging System Light

United States

Canada

This gauge shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gauge reads 100°C (210°F) or less. If a load is being pulled or going up hills, it is normal for the temperature to fluctuate and go over the 113°C (235°F) mark. However, if the gauge reaches the 125°C (260°F) mark, it indicates that the cooling system is working beyond its capacity.

This 12‐volt battery light comes on briefly when the ignition is turned to ON/RUN, but the engine is not running, as a check to show it is working. It should go out once the engine has been started. If it stays on, or comes on while driving, there could be a problem with the 12‐volt charging system. Have the vehicle serviced by your dealer. A 12‐volt charging system Driver Information Center (DIC) message may also appear. See Driver Information Center (DIC) on page 5‑11 for more information. This light could indicate that there are electrical problems.
