to take the key with you.
Trunk
To open the trunk from the outside, press the
trunk release button on the Remote Keyless
Entry (RKE) transmitter.
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See

The Engine Will Remain Running When:

The engine, transaxle, or hybrid battery is
not warmed up yet.
The outside temperature is approximately
−4°F (−20°C).
When the A/C is in Normal Mode.
A/C is in Hybrid Mode and the climate control
system is working to cool the vehicle. See
Automatic Climate Control System on
page 154for more information.
Defrost is selected.
The shift lever is in PARK (P), NEUTRAL (N),
REVERSE (R), INTERMEDIATE (I) or
LOW (L).
The hybrid battery pack charge is low.
The 12V vehicle battery charge is low, or
loads are high.
The hood is not fully closed.
The Engine Will Restart When:

The brake pedal is released.
The accelerator pedal is applied.
When shifting out of DRIVE (D) to any
other gear.
If the A/C button is selected, the duration of
the AUTO STOP will depend on the outside
temperature. This economy mode improves
fuel economy by limiting the effects of the air
conditioning. The warmer it is outside, the
shorter the time before the engine is restarted
to provide cabin cooling.
The climate control system is turned from Off
to On (econ or normal A/C, or oor/
defog/defrost) SeeAutomatic Climate Control
System on page 154for more information.

Climate Controls
Automatic Climate Control System
You can automatically control the heating, cooling,
and ventilation in your vehicle.
Climate Control Inuence on Hybrid
Operation and Fuel Economy
The climate control system is dependent upon other
vehicle systems for heat and power input. Certain
climate control settings can lead to higher fuel
consumption and/or fewer Auto Stops.The following are climate control settings that use
more fuel:
Normal air conditioning mode.
The defrost mode.
Extreme temperature settings, such as 60°F
(15°C) / 90F (32°C).
High fan speed settings.
The following can help reduce fuel consumption:
Use of the full automatic control method as
described under Automatic Operation.
Use hybrid air conditioning, instead of the
normal air conditioning.
Select a temperature setting that is higher in
hot weather and lower in cold weather.
Only use defrost to clear the windows.
These suggestions will help to reduce fuel
consumption, but may reduce overall comfort.

Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed knob and the air delivery mode knob to
activate the automatic system. When automatic
operation is active the system controls the
inside temperature and air delivery.
Use the steps below to place the entire system in
full automatic control:
1. Turn the fan knob and the mode knob to the
AUTO position.
The current set temperature displays. When
AUTO is selected, the air conditioning
operation and air inlet is automatically
controlled. The air conditioning compressor
runs while the outside temperature is
over about 40°F (4°C). The air inlet is normally
set to outside air. If it is hot outside, the air
inlet can automatically switch to recirculate
inside air to help quickly cool down your
vehicle.
2. Set the temperature.
An initial setting of 73°F (23°C) is
recommended. Allow about 20 minutes for the
system to regulate. Press the
worxarrow
temperature buttons to adjust the temperaturesetting as necessary. If the temperature is set
at 60°F (15°C) the system remains at the
maximum cooling setting. If the temperature is
set at 90°F (32°C) the system remains at the
maximum heat setting. Choosing either
maximum setting does not cause the vehicle to
heat or cool any faster.
Be careful not to cover the sensor located on
the top of the instrument panel near the
windshield. This sensor regulates air
temperature based on the intensity of the sun.
Also do not cover the sensor grille on the
lower right side of the climate control
faceplate, as this regulates the inside
temperature.
To avoid blowing cold air at engine start-up in
cold weather, the system delays turning on
the fan until warm air is available. The length
of delay depends on the engine coolant
temperature. Turning the fan knob overrides
this delay and changes the fan to the selected
speed.

When the weather is cool or damp, operating the
system in recirculation for extended periods of
time can cause fogging of the vehicle’s windows.
To clear the fog, select either defog or defrost.
Make sure the air conditioning is on. Allow the air
conditioning to run automatically to help
dehumidify the air.
N(Hybrid Air Conditioning):The hybrid A/C
function tries to balance fuel economy and air
conditioning comfort. When hybrid A/C is used in
warm weather, your vehicle gets better fuel
economy and/or more frequent autostops at the
expense of cabin cooling performance compared
to normal air conditioning.
Maximum Air Conditioning
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
For quick cool down on hot days, do the
following:
1. Select the
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
hrecirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of
time may cause the air inside of your vehicle
to become too dry. To prevent this from
happening, after the air in your vehicle has cooled,
turn the recirculation mode off.

Electronic Stability Control Indicator
Light
Your vehicle may have
the Electronic Stability
Control (ESC) system.
You may feel or hear the system working, this is
normal. SeeElectronic Stability Control on
page 219for more information.
When the ESC indicator light is on and either the
SERVICE ESC or ESC OFF Driver Information
Center (DIC) message is displayed, the system will
not assist the driver to maintain directional
control of the vehicle. Adjust your driving
accordingly. SeeDIC Warnings and Messages on
page 182for more information.
Engine Coolant Temperature
Warning Light
This light indicates that
the engine coolant has
overheated or the
radiator cooling fan is
not working.
This light will come on briey when you turn on
the ignition as a check to show you it is working.
If the light comes on and the vehicle has been
operating under normal driving conditions, pull off
the road, stop the vehicle, and turn off the
engine as soon as possible.

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check
all uid levels and also the brakes, tires,
cooling system, and transaxle. These parts
can work hard on mountain roads.
{CAUTION:
If you do not shift down, the brakes could
get so hot that they would not work well.
You would then have poor braking or
even none going down a hill. You could
crash. Shift down to let the engine assist
the brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with
the ignition off is dangerous. The brakes
will have to do all the work of slowing
down. They could get so hot that they
would not work well. You would then have
poor braking or even none going down a
hill. You could crash. Always have the
engine running and your vehicle in gear
when you go downhill.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when
you go down a steep or long hill.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at
speeds that let you stay in your own lane.

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 264
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

Automatic Transaxle Fluid
It is not necessary to check the transaxle uid
level. A transaxle uid leak is the only reason for
uid loss. If a leak occurs, take your vehicle to
the retailer service department and have it repaired
as soon as possible.
Change the uid at the intervals listed inAdditional
Required Services on page 359, and be sure to
use the transaxle uid listed inRecommended
Fluids and Lubricants on page 365.
Notice:Use of the incorrect automatic
transaxle uid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
uid listed inRecommended Fluids and
Lubricants on page 365.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 275.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F
(−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
