HYBRID OPERATION
The Hybrid is a whole new kind of SUV that combines electric and
gasoline propulsion without compromise, to provide breakthrough
performance and efficiency. It requires no special fuels and never has to
be plugged in. Familiarizing yourself with these unique characteristics
will help ensure optimal performance from your new vehicle.
Normal vehicle operation
Starting:Turn the ignition key to the START position while your vehicle
is in Park (P). The gas engine will turn on,accompanied by the green
“ready indicator” light. Your engine may shut off shortly after starting,
depending on temperature and battery charge level. This is a natural
part of your Hybrid’s fuel-saving features. The “ready indicator” light will
stay on, and you do not need to restart the vehicle.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin for
occupant comfort.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the vehicle operates in electric-only mode. Conditions that
may cause the engine to start up or remain running include:
•Driving request for moderate to rapid acceleration
•Vehicle speed above 40 mph (65 kph)
•Ascending a hill
•ECON mode not selected (while Climate Control is ON)
•Selection of climate control defrost mode or defrost/floor mode
•Charge level of high voltage battery is low
•Very high or low outside temperature (to provide system
cooling/heating)
Stopping:The gas engine may shut off to conserve fuel as you come to
a stop. Restarting the vehicle is not required. Simply step on the
accelerator when you are ready to drive.

The “ECON” mode turns itself off when you select defrost or
defrost/floor mode, although on cold days, you may still experience
engine shut-down while in defrost or defrost/floor mode.
Drive Habits:Aggressive driving increases the amount of energy
required to move your vehicle. In general, better fuel economy is
achieved with mild to moderate acceleration and deceleration. Moderate
braking is particularly important since it allows you to maximize the
energy captured by the regenerative braking system.
NOTE:Having your engine running is not always an indication of
inefficiency – in some cases it is actually more efficient than driving in
electric mode.
Additional Tips:
•Do not carry extra loads
•Be mindful of adding external accessories that may increase
aerodynamic drag
•Observe posted speed limits
•Perform all scheduled maintenance
•There is no need to wait for your engine to “warm up”. The vehicle is
ready to drive immediately after starting

Question Answer
How far can I go in Electric Drive
if I run out of gas?Running out of gas is not
recommended. However, you may
be able to go about one mile,
driving at 30 mph (48 km/h), if the
battery has a normal state of
charge.
What is the engine oil change
service interval?The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See theScheduled maintenance
guidechapter.
Can I put E10 or E85 in my
vehicle, and how will it affect my
fuel economy?Your hybrid vehicle can use E10
(10% ethanol, 90% gasoline) fuel,
but you may notice slightly
reduced fuel economy because
ethanol contains less energy per
gallon than gasoline. Your hybrid
vehicle is not designed to use E85
(85% ethanol).
How long will my high voltage
battery last? Does it need
maintenance?The high voltage battery system is
designed to last the life of the
vehicle and requires no
maintenance.
Can you charge the battery with a
plug into an A/C outlet?There are no provisions for
charging the high voltage battery
from a power supply external to
the vehicle.

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, theService engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds theService
engine soonlight blinks eight times, it means that the vehicle is not
ready for I/M testing. See theReadiness for Inspection/Maintenance
(I/M) testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.

Determining if the Personal Safety Systemis operational
The Personal Safety Systemuses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lightsection in theInstrument Clusterchapter.
Routine maintenance of the Personal Safety Systemis not required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety Systemserviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety restraints precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
where they can be properly restrained.
WARNING:Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an
airbag supplemental restraint system (SRS) is provided.

Seating and Safety Restraints
121

WARNING:Any alteration/modification to the front passenger
seat may affect the performance of the front passenger sensing
system.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the status of the system. Refer toAirbag readinesssection in
theInstrument Clusterchapter. Routine maintenance of the airbag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Seat-mounted side airbag system
WARNING:Do not place objects or mount equipment on or
near the airbag cover on the side of the seatbacks of the front
seats or in front seat areas that may come into contact with a
deploying airbag. Failure to follow these instructions may increase the
risk of personal injury in the event of a collision.
WARNING:Do not use accessory seat covers. The use of
accessory seat covers may prevent the deployment of the side
airbags and increase the risk of injury in an accident.
WARNING:Do not lean your head on the door. The side airbag
could injure you as it deploys from the side of the seatback.
