Storage Areas

Power Outlet Alternating Current

Your vehicle may have a power outlet that can be used to plug in electrical equipment that uses a maximum limit of 150 watts.

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

An indicator light on the outlet turns on to show it is in use. The light comes on when the ignition is in ON/RUN and equipment requiring less than 150 watts is plugged into the outlet, and no system fault is detected.

The indicator light does not come on when the ignition is in LOCK/OFF or if no equipment is plugged into the outlet.

If you try to connect equipment 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 the following electrical equipment and may not work properly if these items are plugged into the power outlet:

• 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 5-3.

2-2

Starting and Operating Your Vehicle

Starting Your Vehicle

{CAUTION:

Exiting your vehicle, without ﬁrst shifting into PARK (P), may cause the vehicle to move, and you or others can be seriously injured.

CAUTION: (Continued)

Because your vehicle has the Automatic Engine Start/Stop feature, the vehicle’s engine might seem to be shut off when you come to a complete stop. However, once the brake pedal is released, the vehicle can move. The vehicle’s engine can also restart at any time.

Shift to PARK (P) and turn the ignition to LOCK/OFF, before exiting the vehicle.

Start the engine as you would any other engine. See “Starting Your Engine” in the owner manual for more information on starting. The hybrid system provides very quiet engine starting. If pulling a trailer with trailer brakes, see Towing a Trailer on page 4-2 for more information.

2-3

Auto Stop

The vehicle has an Auto Stop feature. After a successful engine start, the Hybrid Powertrain Control Module (HPCM) may turn off the engine and operate in the Auto Stop mode. Some of the vehicle conditions that allow the engine to stop running and enter the Auto Stop mode are:

• Ignition switch is in the ON/RUN position.

• The hood is closed.

• The gear selector is in PARK (P), NEUTRAL (N) or

DRIVE (D).

• The hybrid battery is at an acceptable state of

charge.

• The hybrid battery voltage, temperature or power

limits are not exceeded. In very hot conditions, Auto Stop may be unavailable until the hybrid battery has cooled.

• The engine is at operating temperature.

If you are on an incline, the hybrid drive motor can help keep your vehicle from rolling backwards, even if the engine is in Auto Stop.

With your foot off the brake and the vehicle on level ground, the hybrid drive motor may cause your vehicle to roll slowly forward, even when the engine is in Auto Stop.

To be sure your vehicle will not move or roll, always keep your foot ﬁrmly on the brake pedal until you are ready for the vehicle to move.

Engine OFF and AUTO STOP modes are indicated on the tachometer display. When the tachometer needle indicates OFF, the engine is not running and will remain off until the ignition key is placed in the START position or a remote vehicle start is performed. When the tachometer needle indicates AUTO STOP, the engine is not running but may Auto Start at any time without notice. See Tachometer on page 3-4 for more information.

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.

2-4

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. Some of the vehicle conditions that may cause the HPCM to Auto Start the engine are:

• The hood is opened.

• The gear selector is in MANUAL MODE (M) or

REVERSE (R).

• The hybrid battery state of charge is too low.

• The hybrid battery voltage, temperature or power

limits are exceeded.

• The engine is not at operating temperature.

• Acceleration demands require the use of the engine.

EV Mode

The vehicle also has an EV mode which uses only the electric motor to move the vehicle. Depending on the state of battery charge, the vehicle can travel up to two miles in EV mode. EV mode is unavailable when the vehicle is out of fuel.

While lightly accelerating, the vehicle will be propelled in EV mode.

If increased acceleration is required, or the vehicle achieves a speed of approximately 25 mph (40 km/h), the engine will start automatically. The engine will shut off at speeds below 25 MPH (40 km/h) unless the transmission is in MANUAL MODE (M) or Auto Stop is disabled.

During heavy acceleration, both the engine and hybrid electric motors supply power. A sensation similar to a transmission gear change can be felt as the transmission changes modes. Engine RPM may remain above 4,000 RPM for a longer period during hard acceleration.

2-5

Automatic Transmission Operation

Your vehicle has an M99–EVT transmission, and has an electronic shift position indicator within the instrument panel cluster. The electronic shift position indicator displays when the shift lever is moved out of PARK (P).

There are several different positions for the shift lever.

See ““Range Selection Mode” later in this section.

PARK (P): This position locks the rear wheels. It is the best position to use when you start your engine because the vehicle cannot move easily.

When parked on a hill, especially when the vehicle has a heavy load, you may notice an increase in the effort to shift out of PARK (P). See “Shifting Into PARK (P)” in the Index of vehicle’s owner manual for more information.

{CAUTION:

It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. Your vehicle can roll.

Do not leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See “Shifting Into Park (P)” in the Owner Manual. If you are pulling a trailer, see Towing a Trailer on page 4-2.

REVERSE (R): Use this gear to back up.

Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped.

2-6

To rock your vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see “If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow” in the Index of the vehicle’s owner manual.

NEUTRAL (N): In this position, the engine and transmission are not connected with the wheels. To restart while the vehicle is already moving, use NEUTRAL (N) only.

{CAUTION:

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is ﬁrmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while your engine is running at high speed.

Notice: Shifting out of PARK (P) or NEUTRAL (N) with the engine running at high speed may damage the transmission. The repairs would not be covered by your warranty. Be sure the engine is not running at high speed when shifting your vehicle.

DRIVE (D): This position is for normal driving. It

provides the best fuel economy for your vehicle. If you need more power for passing, and you are:

• Going less than about 35 mph (55 km/h), push the

accelerator pedal about halfway down.

• Going about 35 mph (55 km/h) or more, push the

accelerator all the way down.

DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. You may want to shift the transmission to a lower gear selection if the transmission shifts too often.

Downshifting the transmission in slippery road conditions could result in skidding, see “Skidding” under “Loss of Control” in the Index of the vehicle’s owner manual.

When temperatures are very cold, the transmission’s gear shifting may be delayed providing more stable shifts until the engine warms up. Shifts may be more noticeable with a cold transmission. This difference in shifting is normal.

2-7

MANUAL MODE (M): This position lets drivers select the range of gears appropriate for current driving conditions. If your vehicle has this feature, see “Range Selection Mode” later in this section.

Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

Your vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine will be able to maintain vehicle speed by analyzing things such as throttle position, vehicle load, and hill grade. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this may appear to be a delayed shift, however the transmission is operating normally.

Range Selection Mode

The Range Selection Mode controls the vehicle’s transmission.

To use this feature, do the following:

1. Move the shift lever to the MANUAL MODE (M).

2. Press the plus/minus button, to upshift or downshift selecting the desired range of gears for your current driving conditions.

2-8

While in the MANUAL MODE (M) a number displays next to the M, indicating the current gear that has been selected. The number displayed in the gear indicator is the highest gear that can be used. However, your vehicle can automatically shift to lower gears as it adjusts to driving conditions. This means that all gears below that number are available. When THIRD (3) is selected, FIRST (1) through THIRD (3) gears are automatically shifted by the vehicle, but FOURTH (4) cannot be used until the plus/minus button located on the steering column lever is used to change to the gear.

The Range Selection Mode controls the vehicle and engine speed while driving down a hill or towing a trailer, by allowing you to select a desired range of gears.

When you move the shift lever into M, the transmission will default to M4. In this gear range, effective engine braking will occur at speeds above 45 mph (72 km/h).

Pushing the minus (−) button on the shift lever will

change the gear range to M3. In this gear range, effective engine braking will occur at speeds above 35 mph (56 km/h).

Pushing the minus (−) button on the shift lever will

change the gear range to M2. In this gear range, effective engine braking will occur at speeds above 25 mph (40 km/h).

Pushing the minus (−) button on the shift lever will

change the gear range to M1. In this gear range, effective engine braking will occur at speeds above 10 mph (16km/h).

When operating in MANUAL MODE (M), Auto Stop is disabled. Vehicle efficiency is decreased operating in MANUAL MODE (M) compared to DRIVE (D).

Cruise control can be used while using the Range Selection Mode.

Regenerative Braking

Your vehicle uses a hybrid technology known as regenerative braking. This technology enables the electric drive motor on your vehicle to operate as a generator when you are coasting or braking. The energy of the moving vehicle is used to recharge the vehicle’s high voltage hybrid battery.

The conventional hydraulic disc brakes on your vehicle work in partnership with the regenerative braking to insure effective braking in all situations, such as when the high voltage hybrid battery is fully charged or a high braking demand is requested. Four wheel, four channel ABS allows the vehicle to maintain steering control during braking and Electronic Stability Control (ESC) helps you to keep your vehicle in control in unfavorable conditions. These systems, however, are not a substitute for safe driving practices.

2-9

The braking system is computer controlled and uses the information provided by the driver’s input at the brake pedal to seamlessly blend the regenerative braking with the conventional hydraulic disc brakes to meet any requirements for deceleration. The brake controller in your vehicle has a high pressure accumulator to provide the hydraulic pressure to the disc brakes in response to the driver’s input. The controller interprets the braking request and uses regenerative braking, conventional hydraulic braking or a combination of both as necessary. Since the controller applies the hydraulic brakes through its high pressure accumulator, you may occasionally hear the motor driven pump in the controller when it runs to recharge the system. This recharging cycle is normal.

Even though the conventional disc brakes are operated by the controller, there is still a direct mechanical connection with the brake pedal and the hydraulic brake system in the unlikely event of a controller problem. See “Warning Lights, Gages, and Indicators” and “Driver Information Center (DIC)” in the Index of the vehicle’s owner manual. In the event of a controller problem, your brake pedal may be harder to push and the stopping distance may be longer.

Running the Vehicle While Parked

It is better not to park with the engine running. But if you ever have to, here are some things to know.

{CAUTION:

Exiting your vehicle, without ﬁrst shifting into PARK (P), may cause the vehicle to move, and you or others can be seriously injured. Because your vehicle has the Automatic Engine Start/Stop feature, the vehicle’s engine might seem to be shut off when you come to a complete stop. However, once the brake pedal is released, the vehicle can move. The vehicle’s engine can also restart at any time.

Shift to PARK (P) and turn the ignition to LOCK/OFF, before exiting the vehicle.

Follow the proper steps to be sure your vehicle will not move. See “Shifting Into PARK (P)” in the owner manual for more information.

If you are pulling a trailer, see Towing a Trailer on page 4-2 for more information.

Climate Controls

For more information on the vehicle’s climate control system, see “Climate Control System” in the owner manual Index.

Electric Air Conditioning Compressor

This hybrid vehicle has a 300 volt, electrically powered air conditioning compressor. This allows for continuous air conditioning operation and passenger comfort, even while the hybrid engine cycles on and off.

When operating the climate control system, select the AUTO mode and the desired temperature setting. The climate control system will automatically adjust the fan speed and airﬂow direction. The climate control system continues to adjust the climate control settings chosen for best use of electrical power.

To get maximum engine off time, select a warmer temperature setting or turn off the air conditioning to shut off the compressor. Continuous air conditioning use can cause the engine to autostart more frequently.

Some noise may be heard occasionally from the compressor, especially when air conditioning use is high and the engine has turned off.

3-2

Warning Lights, Gages, and Indicators

Instrument Panel Cluster

United States version shown, Canada similar

The instrument cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, about how much fuel you have, and many other things you will need to know to drive safely and economically.

3-3

Tachometer

United States version

shown, Canada similar

When the gas engine is off and the key is in the ON/RUN position, the tachometer indicates the state of the vehicle:

• AUTO STOP position indicates that the vehicle is still

able to move and the engine could restart, by an Auto Start, at any time.

• OFF position indicates that either the vehicle was

turned off or the engine has stalled.

When the engine is on, the Tachometer indicates the engine’s revolutions per minute.

Charging System Light

This light will come on brieﬂy when you turn on the ignition to ACC/ACCESSORY or ON/RUN, but the engine is not running, as a check to show you 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 charging system. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-11 for more information. This light could indicate that there are electrical problems. Have it checked right away. If you must drive a short distance with the light on, be certain to turn off all the accessories, such as the radio and air conditioner.

3-4

Fuel Economy Gage

United States

This gage shows when the vehicle is operating at a fuel efficient point.

By modifying your driving behavior to increase the economy time during driving, your fuel mileage will be improved. When driving in a way that increases the fuel economy, the indicator moves into the high efficiency band. When driving in a way that decreases fuel economy, the indicator moves into the less efficient band. There are several zones on the gage, indicating several levels of efficiency when accelerating or decelerating.

Canada

Brake System Warning Light

With the ignition in ON/RUN, the brake system warning light will come on when you set the parking brake. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 5 mph (8 km/h).

Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well.

If the warning light comes on and a chime sounds there could be a brake problem. Have your brake system inspected right away.

3-5

This light may also come on due to low brake ﬂuid. See your owners manual for more information.

If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push or may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-2.

Anti-lock Brake System (ABS) Warning Light

United States

This light should come on brieﬂy when you turn the ignition key to ON/RUN. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem.

Canada

{CAUTION:

Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service.

3-6

For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is in ON/RUN.

That is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem.

If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, your vehicle still has brakes, but not antilock brakes.

If the regular brake system warning light is also on, your vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-5.

For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-11 for all brake related DIC messages.

StabiliTrak®Indicator Light

If the vehicle has StabiliTrak®this warning light should come on brieﬂy when the ignition is in ON/RUN.

If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem.

When this warning light ﬂashes, the system is on. Driving should be adjusted accordingly.

If it stays on when while driving, there may be a problem with the StabiliTrak may need service.

system and the vehicle

Engine Coolant Temperature Gage

United States Canada

This gage shows the engine coolant temperature.

It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to ﬂuctuate and go over the 235°F (113°C) mark. However, if the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity.

3-7

Oil Pressure Gage

United States

The oil pressure gage 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 29 to 80 psi (200 to 550 kPa). In certain situations, such as long extended idles on hot days, it could read as low as 15 psi (105 kPa) and still be considered normal.

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 your oil as soon as possible.

Canada

{CAUTION:

Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced.

Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil.

AUTO STOP

When the engine goes into Automatic Engine Stop, the oil pressure gage will drop to zero when the tachometer is at the AUTO STOP position. This is normal and oil pressure will return to normal operating range once the engine starts.

See Starting Your Vehicle on page 2-3 for more information.

AUTO STOP will display in the Driver Information Center (DIC) when the vehicle speed is zero. See DIC Warnings and Messages on page 3-11 for more information.
