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 2-33.
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. See
Winter 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 after you 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 2-30.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.

The Forward Collision Alert (FCA) system provides an
audible and visual alert if you approach a vehicle
too quickly that is directly ahead. FCA also provides a
visual alert with no audible alert if you are following
another vehicle much too closely. The FCA alert symbol
is located on top of the instrument panel to the right
of the driver. FCA uses the Adaptive Cruise Control
radar to detect a vehicle directly ahead, in your path,
within a distance of 328 ft (100 m) and operates at
speeds above 20 mph (32 km/h).
{CAUTION:
FCA is only a warning system and does not
apply the brakes. When you are approaching a
vehicle or object too rapidly or when you are
following a vehicle too closely that is ahead of
you, FCA may not provide you with enough
time to avoid a collision. FCA is not designed
to warn the driver of pedestrians or animals.
Your complete attention is always required
while driving and you should be ready to
take action and apply the brakes. For more
information, seeDefensive Driving on page 4-2.The FCA control is located
on the steering wheel.
To enable or disable FCA, press the Adaptive Cruise
Control button. SeeAdaptive Cruise Control on
page 3-19.
FCA is enabled when the green light on the button
is lit. FCA is disabled when the green light is off.

Cruise Control
With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This is helpful on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h). When cruise control
is on, you will see a cruise light on the instrument
panel cluster.
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. SeeTraction
Control System (TCS) on page 4-9. When road
conditions allow you to safely use it again, you may
turn the cruise control back on.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
3-16

The cruise control buttons
are located on left side of
the steering wheel.
I(On):This position activates the system.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
–SET (Set):Press this button to set the speed.
[(Cancel):Press this button to cancel cruise control.
Cruise control will not work if your parking brake is
set, or if the master cylinder brake uid level is low.
If you apply your brakes, the cruise control will shut off.The cruise light on the instrument panel cluster will
come on after the cruise control has been set to
the desired speed.
1. Press the cruise control button.
2. Get up to the speed you want.
3. Press the SET button located on the steering wheel
and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once the vehicle is traveling approximately
25 mph (40 km/h) or more, you can press the
RES (resume/accelerate) button to return to your
desired preset speed. The cruise light will be displayed
again.
The vehicle will return to and stay at your preset speed.
If you press and hold the RES button, the vehicle
speed will increase until you release the button or apply
the brake. Unless you want to go faster, do not press
and hold the RES button.
3-17

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Applying the
brake or shifting into a lower gear will take you out
of cruise control. If you need to apply the brake or shift
to a lower gear due to the grade of the downhill
slope, you may not want to attempt to use your cruise
control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Adaptive Cruise Control is an enhancement to traditional
cruise control. It allows you to keep cruise control
engaged in moderate traffic conditions without having to
constantly reset your cruise control. Adaptive Cruise
Control uses radar to detect a vehicle directly ahead in
your path, within a distance of 330 ft (100 m), and
operates at speeds above 25 mph (40 km/h). When it is
engaged by the driver, the system can apply limited
braking or acceleration of the vehicle automatically to
maintain a selected follow distance to the vehicle
ahead. Braking is limited to 0.25 g’s (2.45 m/sec2) of
deceleration, which is comparable to moderate
application of the vehicle’s brakes. To disengage
Adaptive Cruise Control, apply the brake. If no vehicle
is in your path, your vehicle will react like traditional
cruise control.
{CAUTION:
Adaptive Cruise Control will not apply hard
braking or bring the vehicle to a complete
stop. It will not respond to stopped vehicles,
pedestrians or animals. When you are
approaching a vehicle or object, Adaptive
Cruise Control may not have time to slow your
vehicle enough to avoid a collision. Your
complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
seeDefensive Driving on page 4-2.
