Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management
This vehicle's engine may be
equipped with Active Fuel
Management, which allows the
engine to operate on either all of its
cylinders, or in reduced cylinder
operation, depending on the driving
conditions.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
reduced cylinder operation mode,
allowing the vehicle to achieve
better fuel economy. When greater
power demands are required, such
as accelerating from a stop,
passing, or merging onto a freeway,
the system will maintain full-cylinder
operation.
If the vehicle has an Active Fuel
Management indicator, see Driver
Information Center (DIC) for more
information on using this display.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation.
See Shifting Into Park 0226 and
Engine Exhaust 0229.
If the vehicle is left parked and
running with the RKE transmitter
outside the vehicle, it will continue
to run for up to half an hour.
If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will continue to
run for up to an hour.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.
