Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set. And,
if you leave the vehicle with the engine running,
it could overheat and even catch re. You or
others could be injured. Do not leave your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After
you have moved the shift lever into PARK (P), hold
the regular brake pedal down. Then, see if you
can move the shift lever away from PARK (P) without
rst pushing the button. If you can, it means that the
shift lever was not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may nd it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-31.
When you are ready to drive, move the shift lever out of
PARK (P) 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 transaxle, so you
can pull the shift lever out of PARK (P).

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass, or other
things that can burn.
Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot see
or smell. It can cause unconsciousness and
death.
You might have exhaust coming in if:
Your exhaust system sounds strange or
different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over road
debris.
Repairs were not done correctly.
Your vehicle or exhaust system has been
modied improperly.
If you ever suspect exhaust is coming into your
vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-26.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your 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 your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) on page 2-31.
If you are parking on a hill and if you are pulling a trailer,
also seeTowing a Trailer on page 4-38.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will automatically
cool the vehicle if the temperature is greater than
90°F (32°C) and heat the vehicle if the temperature
is below 37°F (3°C). If the temperature is between
37°F (3°C) and 90°F (32°C), the last control setting
selected when the engine was running will be used.
Normal operation and the last setting of the climate
control system will return after the key is turned to
the RUN position.
Operation
OFF:Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the knob by this symbol, located on
the left side of the climate control panel, clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed will be temporarily reduced between the
transition to a new mode. The fan will resume the original
speed when the transition to the new mode is complete.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
3-22

On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close them.
This helps to reduce the time it takes for the vehicle to
cool down. It also helps the system to operate more
efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are two modes
to clear frost or fog from the windshield. Use the defog
mode to clear the windows of condensation and to warm
the vehicle’s occupants.Use the defrost mode to remove frost or condensation
from the windshield quickly. Recirculation cannot be
selected when in these modes (the indicator light will
come on when pressed).
See “Rear Window Defogger” later in this section for
information on clearing the rear window of fog or ice.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets. When you select this mode, the system
turns recirculation off and runs the air conditioning
compressor unless the outside temperature is near or
below freezing. Pressing the recirculation button will have
no effect other than turning on the indicator light while in
defog mode.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with some
air directed to the oor outlets. When you select this
mode, the system turns recirculation off and runs the air
conditioning compressor unless the outside temperature
is near or below freezing. Pressing the recirculation
button will have no effect other than turning on the
indicator light while in defrost mode.
3-24

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press the button to turn the rear window
defogger on or off. An indicator light below the button will
come on to let you know that the rear window defogger
is activated.
The rear window defogger will only work when the
ignition is in run. The rear window defogger will stay
on for approximately 20 minutes after the button is
pressed, unless the ignition is turned to ACCESSORY
or RUN. If turned on again, the defogger will only run
for approximately 20 minutes before turning off.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar to
the defogger grid.
Dual Automatic Climate Control
System
Your vehicle may have this climate control system.
The heating, cooling and ventilation can be controlled
with it.
Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed. There might be a
delay of two to three minutes before the fan comes on
when the automatic operation is used in cold weather.
