214 Driving and Operating
Parking over Things
That Burn
{ WarningThings 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 Vehicles with V8 engines may have
Active Fuel Management. This
system allows the engine to operate
on either all or half of its cylinders,
depending on the driving conditions.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder 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) 0 151 for
more information on using this
display.
Extended Parking It is better not to park with the
vehicle running. If the vehicle is left
while running, follow the proper
steps to be sure the vehicle will not
move and there is adequate
ventilation.
See Shifting Into Park 0 212 and
Engine Exhaust 0 215 .
For vehicles with pushbutton start,
if the vehicle is left parked while
running and the Remote Keyless
Entry (RKE) transmitter is outside
the vehicle, the vehicle will turn off
after one hour.
If the vehicle is left parked while
running and the RKE transmitter is
inside, the vehicle will turn off after
two hours.
Vehicles without pushbutton start
will run indefinitely, or until the
ignition is turned off. Automatic Transmission
The timer will reset if the vehicle is
shifted out of P (Park) while it is
running.
Manual Transmission
The timer will reset if the vehicle
speed is greater than 4 km/h
(2.5 mph).

240 Driving and Operating braking may feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{ WarningACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when a
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes. ACC Automatically Disengages
ACC may automatically disengage
and you will need to manually apply
the brakes to slow the vehicle if:
.
Your vehicle speed goes below
the minimum speed of 16 km/h
(10 mph).
.
The sensors are blocked.
.
The Traction Control System
(TCS) or electronic stability
control system has activated or
been disabled.
.
There is a fault in the system.
.
The radar falsely reports a
blockage when driving in a
desert or remote area with no
other vehicles or roadside
objects. A DIC message may
display to indicate that ACC is
temporarily unavailable.
A message will appear on the DIC
indicating that cruise is disengaging.
The ACC indicator will turn white
when ACC is no longer active. ACC Override
If using the accelerator pedal while
ACC is active, a warning message
in the DIC and in the HUD,
if equipped, will indicate that
automatic braking will not occur.
See Vehicle Messages 0 157 . ACC
will resume operation when the
accelerator pedal is not being
pressed.
{ WarningThe ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{ Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,

Engine Oil To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“ Selecting the Right Engine Oil ”
in this section.
.
Check the engine oil level
regularly and maintain the
proper oil level. See “ Checking
Engine Oil ” and “ When to Add
Engine Oil ” in this section.
.
Change the engine oil at the
appropriate time. See Engine Oil
Life System 0 285 .
.
Always dispose of engine oil
properly. See “ What to Do with
Used Oil ” in this section. Checking Engine Oil If equipped, the ENGINE OIL LOW
ADD OIL message displays when
the engine oil level may be too low.
Check the oil level before filling to
the recommended level. If the oil is
not low and this message remains
on, see your dealer.
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0 280 for the location.
{ WarningThe engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
Follow these guidelines:
.
To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
