STARTING
Positions of the ignition
1. Off— locks the gearshift lever
and allows key removal.Note:In
order to switch off the engine while
the vehicle is in motion, shift to
neutral and use the brakes to bring
the vehicle to a safe stop. After the
vehicle has stopped, turn the engine
off and shift into park. Then, turn
the key to the accessory or off position.
2. Accessory— allows the electrical accessories such as the radio to
operate while the vehicle is not running.
3. On— all electrical circuits operational and warning lights will
illuminate. This is the position the key is in when you’re driving.
4. Start— starts the vehicle and electrical power systems.
Preparing to start your vehicle
Engine starting is controlled by the electronically-controlled
Continuously Variable Transaxle (eCVT). For more information on
starting the vehicle, refer toStarting the vehiclein this chapter.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING:Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine. SeeGuarding against
exhaust fumesin this chapter for more instructions.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.

Important safety precautions
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure vehicle accessories are off.
•Make sure the parking brake is
set.
•Make sure the gearshift lever is in
P (Park).

3. Turn the key to 3 (on) without
turning the key to 4 (start).
Some warning lights will briefly illuminate. SeeWarning lights and
chimesin theInstrument Clusterchapter for more information
regarding the warning lights.
Starting the vehicle
1. Turn the key to 3 (on) without
turning the key to 4 (start). If there
is difficulty in turning the key,
rotate the steering wheel until the
key turns freely. This condition may
occur when:
•the front wheels are turned
•a front wheel is against the curb
2. Turn the key to 4 (start), then release the key.
After releasing the key from the 4
(start) position, a vehicle symbol
(called the Ready Indicator Light)
will illuminate in the instrument
cluster to indicate the vehicle is
ready to drive. The engine may not start because this hybrid vehicle is
equipped with Silent Key Start (SKS). This fuel saving feature allows
your vehicle to be “ready to drive” without requiring the gas engine to be
running. This light will remain on while the vehicle is on, whether the
engine is running or not, to indicate the vehicle is capable of movement
(using its electric motor, engine, or both). The vehicle’s computer will
determine if an engine start is required at key-on. The engine will start if
it is necessary for cabin heating or windshield defrost. The engine will
also be started when outside temperatures are low.
Note:The vehicle may be turned off at any time by turning the key to
the off position.

3. Once the “Ready Indicator Light” is on, release the parking brake,
apply the brake, shift into gear and drive.
Note:After the engine has started the first time, it may stop running to
conserve fuel after it is warmed-up and the battery is sufficiently
charged.
Note:If the vehicle does not start, put the gearshift lever into P (Park),
turn the ignition off, wait 10 seconds, then attempt to start the vehicle
again. If the vehicle still does not start, it may require refueling, jump
starting, or service. For information on jump starting the vehicle, refer to
Jump startingin theRoadside Emergencieschapter.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).

Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked “Suitable for Use
with Outdoor Appliances.” Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16-gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.
•Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
•Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
•To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
•Make sure that when in operation, the extension cord plug/engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
•Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
•Be sure that the engine block heater, heater cord and extension cord
are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.
•Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.
