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.
See
Manual Mode on page 9‑9.
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.

Tire Sealant and
Compressor Kit
This vehicle has a tire sealant and
compressor kit that can be used to
seal small punctures in the tread
area of the tire.
SeeTire Sealant and Compressor
Kit on page 10‑24 for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat on
page 10‑22.

Instruments and Controls 5-7
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. 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.

Notice: Lack of proper engine oil

This light comes on briefly as a
check it works, when the ignition is
in ON/RUN. If it does not, have the
vehicle serviced.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
During an AUTO STOP there is zero
oil pressure, but this light will not
come on.

BATTERY VOLTAGE
This display shows the current
battery voltage. If the voltage is in
the normal range, the value will
display. For example, the display
may read BATTERY VOLTAGE
13 VOLTS. Your vehicle's charging
system regulates voltage based on
the state of the battery. The battery
voltage may fluctuate when viewing
this information on the DIC. This is
normal. See “Charging System

information. If there is a problem
with the battery charging system,

Driving Information
Steering
This vehicle has On-Demand
Electric-Assist Power Steering
instead of conventional full-time
hydraulic power steering. It uses
electricity supplied by the same
battery which is re-charged by the
regenerative braking system.
Because the system is On-Demand
Electric-Assist, energy is used only
when the steering wheel is turned,
or when the steering gear is used to
help isolate the forces of rough
roads. This system does not use
power steering fluid, making it
maintenance-free.

10-2 Vehicle Care
Vehicle Checks
Doing Your Own
Service Work
{WARNING
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.
{WARNING
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
.Be sure you have sufficient
knowledge, experience, the
proper replacement parts,
and tools before attempting
any vehicle
maintenance task.
.Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt.If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see
“Service
Publications Ordering Information”
in the owner manual.
This vehicle has an airbag system.
Before attempting to do your own
service work, see “Airbag System
Check” in the owner manual.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
“Maintenance Records” in the owner
manual.

10-6 Vehicle Care
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to check
the transmission fluid level. The
only reason for fluid loss is a
transmission leak or overheating the
transmission. If a small leak is
suspected, then use the following
checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer service department and have
it repaired before driving the vehicle
further.
Notice:Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑1. Change the fluid and filter at the
scheduled maintenance intervals
listed in Scheduled Maintenance.
Be sure to use the transmission fluid
listed in
Recommended Fluids and
Lubricants on page 11‑1.How to Check Automatic
Transmission Fluid
Notice: Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Before checking the fluid level,
prepare the vehicle as follows:
1. Start the engine and park the
vehicle on a level surface. Keep
the engine running.
2. Apply the parking brake and place the shift lever in P (Park). 3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, move the
shift lever back to P (Park).
4. Allow the engine to idle (500–800 RPM) for at least
one minute. Slowly release the
brake pedal.
5. Keep the engine running and press the Trip/Fuel button or
trip odometer reset stem until
TRANS TEMP (Transmission
Temperature) displays on the
Driver Information Center (DIC).
6. Using the TRANS TEMP reading, determine and perform
the appropriate check
procedure. If the TRANS TEMP
reading is not within the required
temperature ranges, allow the
vehicle to cool, or operate the
vehicle until the appropriate
transmission fluid temperature is
reached.
