Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
To reset the Engine Oil Life System
on most vehicles:
1. Display OIL LIFE REMAININGon the DIC. If the vehicle does
not have DIC buttons, the
vehicle must be in P (Park) to
access this display.
2. Press and hold the SET/RESET button on the DIC, or the trip
odometer reset stem if the
vehicle does not have DIC
buttons, for more than
five seconds. The oil life will
change to 100%. On all vehicles, the Engine Oil Life
System can be reset as follows:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. Display OIL LIFE REMAINING on the DIC. If the display shows
100%, the system is reset.
See Engine Oil Life System on
page 10‑10.
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol) on
page 9‑78. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑76.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.
.When road and weather
conditions are appropriate,
use cruise control.
.Always follow posted speed
limits or drive more slowly when
conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.

To replace the battery:
1. Separate the transmitter with aflat, thin object, such as a flat
head screwdriver.
.Carefully insert the tool into
the notch located along the
parting line of the
transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
.Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive
side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
If available, this feature allows you
to start the engine from outside of
the vehicle. It may also start up the
vehicle's heating or air conditioning
systems and rear window defogger.
Normal operation of the system will
return after the key is turned to the
ON/RUN position.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off. During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and will
shut off when the key is turned to
ON/RUN. If the vehicle does not
have an automatic climate control
system, during remote start,
manually turn the heated seats on
and off. See
Heated and Ventilated
Front Seats on page 3‑10 for
additional information.
Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using the remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements
on remote starting of vehicles.
Do not use the remote start
feature if the vehicle is low on fuel.
The vehicle may run out of fuel.

2-18 Keys, Doors, and Windows
Windows
{WARNING
Leaving children, helpless adults,
or pets in a vehicle with the
windows closed is dangerous.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke. Never leave a
child, a helpless adult, or a pet
alone in a vehicle, especially with
the windows closed in warm or
hot weather.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof (if equipped).
Manual Windows
Turn the hand crank on each door
to manually raise or lower the
manual windows.
Power Windows
{WARNING
Leaving children in a vehicle with
the keys is dangerous for many
reasons. Children or others could
be badly injured or even killed.
They could operate the power
windows or other controls or
even make the vehicle move.
The windows will function and
they could be seriously injured or
killed if caught in the path of a
closing window. Do not leave
keys in a vehicle with children.
When there are children in the
rear seat use the window lockout
button to prevent unintentional
operation of the windows.

Seats and Restraints 3-29
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in
many types of collisions, primarily
because the occupant's motion is
not toward those airbags. SeeWhen
Should an Airbag Inflate? on
page 3‑26 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, see What Makes
an Airbag Inflate? on page 3‑28.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle may have a feature
that may automatically unlock
the doors, turn on the interior
lamps and hazard warning
flashers, and shut off the fuel
system after the airbags inflate.
