Initial Drive Information

Transmission

Range Selection Mode

The Range Selection Mode switch is located on the shift lever. To enable the Range Selection feature, move the column shift lever to the M (Manual) position.

The current range will appear next to the M. This is the highest attainable range with all lower gears accessible. As an example, when 3 (Third) gear is selected, 1 (First) through 3 (Third) gears are available.

Press the plus/minus buttons, located on the steering column shift lever, to select the desired range of gears for current driving conditions. See Automatic Transmission Operation in the owner manual.

Cruise control can be used while the vehicle is in Range Selection Mode.

Four-Wheel Drive

If the vehicle has four-wheel drive, you can send the engine's driving power to all four wheels for extra traction. Read the following before using four-wheel drive.

1-2

Automatic Transfer Case

n (Four-Wheel Drive Low) : This setting delivers

extra torque. You might choose Four-Wheel Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills.

N (Neutral) : Shift the vehicle's transfer case to N (Neutral) only when towing the vehicle. See Recreational Vehicle Towing or Towing Your Vehicle in the index of the Owner Manual.

See Four-Wheel Drive on page 3‑10.

Hybrid Features

The transfer case knob is located to the left of the instrument panel cluster. You can choose among five driving settings:

m (Two-Wheel Drive High): This setting is used for

driving in most street and highway situations.

AUTO (Automatic Four-Wheel Drive) : This setting is ideal for use when road surface traction conditions are variable.

m (Four-Wheel Drive High): Use the four-wheel high

position when you need extra traction, such as on snowy or icy roads or in most off-road situations.

Hybrid Safety Information

This vehicle has a standard 12-volt battery and a high-voltage hybrid battery. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the hybrid battery. See your dealer/retailer if the hybrid battery needs service.

The 12-volt battery cables, in the engine compartment, are clearly labeled. In emergency situations, first responders can cut those cables to disable the high-voltage hybrid battery system.

1-3

Fuel Economy Gage

United States Canada

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

By modifying driving behavior to increase the economy time during driving, fuel mileage will be improved.

See Fuel Economy Gage on page 4‑5.

Automatic Engine Start/Stop Feature

Start the engine as you would any other engine. See “Starting the 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 information.

Auto Stop

The vehicle has an Auto Stop feature. After a successful engine start, the engine may turn off and operate in the Auto Stop mode.

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 hybrid system is on, the engine is not running, but may Auto Start at any time without notice. See Tachometer

page 4‑4

for more information.

1-4

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.

See Starting the Vehicle in the Two‐Mode Hybrid supplement to the owner manual.

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, Warning Lights, Gages, and Indicators and Driver Information Center (DIC) in the owner manual.

1-5

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/retailer 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/retailer if the hybrid battery needs service. See Battery on page 6‑16.

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 6‑2.

Performance and Maintenance

Tire Sealant and Compressor Kit

This vehicle has a tire sealant and compressor kit which can be used to seal small punctures in the tread area of the tire.

Storage Areas

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.

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 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 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 6‑3.

Starting and Operating Your Vehicle

WARNING: (Continued)

Starting the Vehicle

WARNING:

{

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

(Continued)

However, once the brake pedal is released, the vehicle can move. The vehicle’s engine can also restart at any time.

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

Start the engine as you would any other engine. See “Starting the Engine” in the owner manual for more information on starting. If pulling a trailer with trailer brakes, see Towing a Trailer for more information.

on page 5‑8

3-3

Auto Stop

The vehicle has an Auto Stop feature. After a successful engine start, the engine may turn off 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 P (Park), R (Reverse), N (Neutral) or D (Drive).

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.

The vehicle may enter Auto Stop after a remote vehicle start.

If you are on an incline, the hybrid drive motor can help keep the 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 the vehicle to roll slowly forward, even when the engine is in Auto Stop.

Keep your foot firmly on the brake pedal until you are ready for the vehicle to move.

page 4‑4

for more information.

3-4

Auto Start

The hood is opened.

The gear selector is in M (Manual Mode).

The hybrid battery state of charge is too low.

The hybrid battery voltage, temperature or power limits are exceeded.

A remote vehicle start has been requested.

The engine is not at operating temperature.

Acceleration demands require the use of the engine.

EV Mode

The vehicle also has an Electric Vehicle (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.

If increased acceleration is required, or the vehicle reaches approximately 40 km/h (30 mph), the engine will start automatically. The engine shuts off at speeds below 40 km/h (25 mph) unless the transmission is in M (Manual Mode) 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.

3-5

Automatic Transmission Operation

The vehicle has an electronic shift position indicator within the instrument panel cluster.

There are several different positions for the shift lever.

See “Range Selection Mode” later in this section.

P (Park) : This position locks the rear wheels. It is the best position to use when you start the 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 P (Park). See “Shifting Into P (Park)” in the Index of vehicle's owner manual for more information.

WARNING:

{

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

Do not leave the 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 the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park in the Owner Manual. If you are pulling a trailer, see Towing a Trailer on page 5‑8.

3-6

WARNING:

{

If you have Four-Wheel Drive, the vehicle will be free to roll — even if the shift lever is in P (Park) — if the transfer case is in Neutral. So, be sure the transfer case is in a drive gear, Two-Wheel Drive High or Four-Wheel Drive High or Four-Wheel Drive Low — not in Neutral. See “Shifting Into Park” in the Owner Manual.

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

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

To rock the 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.

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

WARNING:

{

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

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

3-7

D (Drive) : This position is for normal driving. It provides the best fuel economy. 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.

D (Drive) or M (Manual Mode) 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 owner manual for more information.

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.

M (Manual Mode) : This position lets drivers select the range of gears appropriate for current driving conditions. If the 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 the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions to reduce rapid upshifts and downshifts. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift. In some cases, this may appear to be a delayed shift, however the transmission is operating normally.

3-8

Range Selection Mode

The Range Selection Mode controls the vehicle's transmission.

To use this feature:

1. Move the shift lever to the M (Manual Mode).

2. Press the plus/minus button to upshift or downshift selecting the desired range of gears.

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.

The vehicle can automatically shift to lower gears as it adjusts to driving conditions. When 3 (Third) is selected, 1 (First) through 3 (Third) gears are automatically shifted by the vehicle, but 4 (Fourth) cannot be used until it is selected.

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 occurs at speeds above 45 mph (72 km/h).

Pushing the minus (−) button on the shift lever reduces the gear range.

In the M3 gear range, effective engine braking occurs at speeds above 35 mph (56 km/h).

In the M2 gear range, effective engine braking occurs at speeds above 25 mph (40 km/h).

In the M1 gear range, effective engine braking occurs at speeds above 10 mph (16 km/h).

When operating in M (Manual Mode), Auto Stop is disabled. For better vehicle efficiency, operate the vehicle in D (Drive) not M (Manual Mode).

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

3-9

Four-Wheel Drive

If the vehicle has four-wheel drive, you can send the engine's driving power to all four wheels for extra traction. Read the following before using four-wheel drive.

Notice: Driving on clean, dry pavement in Four-Wheel-Drive High or Four-Wheel-Drive Low for an extended period of time may cause premature wear on your vehicle's powertrain. Do not drive on clean, dry pavement in Four-Wheel-Drive High or Four-Wheel-Drive Low for extended periods of time.

While driving on clean dry pavement and during tight turns, you may experience a vibration in the steering system.

The vehicle has StabiliTrak Four-Wheel-Drive Low will turn Traction Control and StabiliTrak of the Owner Manual for more information.

off. See StabiliTrak®System in the index

Front Axle

The front axle engages and disengages automatically when you shift the transfer case. Some delay for the axle to engage or disengage is normal.

. Shifting into

Automatic Transfer Case

The transfer case knob is located to the left of the instrument panel cluster.

Use this dial to shift into and out of four-wheel drive.

You can choose among five driving settings:

Indicator lights in the switches show you which setting you are in. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take the vehicle to your dealer/retailer for service. An indicator light will flash while shifting. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting.

3-10

2 m (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy.

AUTO (Automatic Four-Wheel Drive) : This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO, the front axle is engaged, but the vehicle's power is primarily sent to the rear wheels. When the vehicle's software determines a need for more traction, the system will transfer more power to the front wheels. Driving in this mode results in slightly lower fuel economy than Two-Wheel Drive High.

m (Four-Wheel Drive High): Use the four-wheel high

position when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive the vehicle. This is the best setting to use when plowing snow.

n (Four-Wheel Drive Low) : This setting also

engages the front axle and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels. You might choose Four-Wheel Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills.

The vehicle has StabiliTrak Four-Wheel-Drive Low will turn Traction Control and StabiliTrak of the Owner Manual for more information.

{

Shifting the transfer case to N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in N (Neutral). See Parking Brake in the index of the Owner Manual for more information.

N (Neutral) : Shift the vehicle's transfer case to N (Neutral) only when towing the vehicle. See Recreational Vehicle Towing or Towing Your Vehicle in the index of the Owner Manual.

If the SERVICE 4 WHEEL DRIVE message stays on, you should take the vehicle to your dealer/retailer for service. See DIC Warnings and Messages

3-11

Shifting Into Four-Wheel Drive High or AUTO (Automatic Four-Wheel Drive)

Turn the knob to the Four-Wheel High or AUTO position. This can be done at any speed, except when shifting from Four-Wheel Drive Low. The indicator light will flash while shifting. It will remain on when the shift is completed.

Shifting Into Two-Wheel Drive High

Turn the knob to the Two-Wheel High position. This can be done at any speed, except when shifting from Four-Wheel Drive Low.

See “Shifting Out of Four-Wheel Drive Low” later in this section for more information.

Shifting Into Four-Wheel Drive Low

When Four-Wheel Low is engaged, vehicle speed should be kept below 40 mph (64 km/h). Extended high-speed operation in 4L may damage or shorten the life of the drivetrain.

To shift to the Four-Wheel Drive Low position, the ignition must be in ON/RUN and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in N (Neutral). The preferred method for

shifting into Four-Wheel Drive Low is to have the vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel Drive Low position. You must wait for the Four-Wheel Drive Low indicator light to stop flashing and remain on before shifting the transmission into gear.

Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped flashing could damage the transfer case. To help avoid damaging the vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear.

The vehicle may have significant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from N (Neutral) while the engine is running.

If the knob is turned to the Four-Wheel Drive Low position when the vehicle is in gear and/or moving, the Four-Wheel Drive Low indicator light will flash for 30 seconds and not complete the shift unless the vehicle is moving less than 3 mph (5 km/h) and the transmission is in N (Neutral). After 30 seconds the transfer case will shift to Four-Wheel Drive High mode.

Shifting Out of Four-Wheel Drive Low

To shift from Four-Wheel Drive Low to Four-Wheel Drive High, AUTO, or Two-Wheel Drive High, the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in N (Neutral) and the ignition in ON/RUN. The preferred method for shifting out of Four-Wheel Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High position. You must wait for the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High indicator light to stop flashing and remain on before shifting the transmission into gear.

The vehicle may have significant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from N (Neutral) while the engine is running.

If the knob is turned to the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High switch position when the vehicle is in gear and/or moving, the Four-Wheel Drive High, AUTO or Two-Wheel Drive High indicator light will flash for 30 seconds but will not complete the shift unless the vehicle is moving less than 3 mph (5 km/h) and the transmission is in N (Neutral).

Shifting into Neutral

To shift the transfer case into N (Neutral):

1. Make sure the vehicle is parked so that it will not roll.

2. Set the parking brake and apply the regular brake pedal. See Parking Brake in the index of the Owner Manual for more information.

3. Start the vehicle or turn the ignition to ON/RUN.

4. Put the transmission in N (Neutral).

5. Shift the transfer case to Two-Wheel Drive High.

6. Turn the transfer case dial clockwise to N (Neutral) until it stops and hold it there until the N (Neutral) light starts blinking. This will take at least 10 seconds. Then slowly release the dial to the Four‐Wheel Drive Low position. The N (Neutral) light will come on when the transfer case shift to N (Neutral) is complete.

7. If the engine is running, verify that the transfer case is in N (Neutral) by shifting the transmission to R (Reverse) for one second, then shift the transmission to D (Drive) for one second.

8. Turn the ignition to ACC/ACCESSORY, which will turn the engine off.

9. Place the transmission shift lever in P (Park).

10. Release the parking brake prior to moving the vehicle.

11. Turn the ignition to LOCK/OFF.

Shifting Out of Neutral

To shift the transfer case out of N (Neutral):

1. Set the parking brake and apply the regular brake pedal.

2. Turn the ignition to ON/RUN with the engine off, and shift the transmission to N (Neutral).

3. Turn the transfer case dial to the desired transfer case shift position (Two-Wheel Drive High, Four-Wheel Drive High, AUTO).

After the transfer case has shifted out of N (Neutral), the N (Neutral) light will go out.

4. Release the parking brake prior to moving the vehicle.

5. Start the engine and shift the transmission to the desired position.

Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

Shifting Into Park

WARNING:

{

It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow. With four-wheel drive, if the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So, be sure the transfer case is in a drive gear — not in N (Neutral). If you are pulling a trailer, see Towing a Trailer on page 5‑8.

1. Hold the brake pedal down, then set the parking brake.

See Parking Brake in the index of the Owner Manual for more information.

2. Move the shift lever into the P (Park) position by pulling the shift lever toward you and moving it up as far as it will go.

3. Be sure the transfer case is in a drive gear — not in N (Neutral).

4. Turn the ignition key to LOCK/OFF.

5. Remove the key and take it with you. If you can leave the vehicle with the ignition key in your hand, the vehicle is in P (Park).

Leaving the Vehicle With the Engine Running

WARNING:

{

It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set.

If you have four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So be sure the transfer case is in a drive gear — not in N (Neutral).

And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running unless you have to.

If you have to leave the vehicle with the engine running, be sure your vehicle is in P (Park) and the parking brake is firmly set before you leave it. After you move the shift lever into P (Park), hold the regular brake pedal down. Then, see if you can move the shift lever away from P (Park) without first pulling it toward you. If you can, it means that the shift lever was not fully locked into P (Park).

Torque Lock

If parking on a hill and the transmission not shifted into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To find out how, see Shifting Into Park on page 3‑15.

When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake.

If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission, then you will be able to pull the shift lever out of P (Park).
