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

Remote Vehicle Start
This vehicle may have a remote
starting feature that starts the
engine from outside of the vehicle.
/(Remote Start): This button is
located on the RKE transmitter if the
vehicle has remote start.
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 could run out of fuel. If the vehicle has the remote start
feature, the RKE transmitter
functions have an increased range
of operation. However, the range
may be less while the vehicle is
running.
There are other conditions that can
affect the performance of the
transmitter. See
Remote Keyless
Entry (RKE) System on page 2‑3
for additional information.

Keys, Doors, and Windows 2-21
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when a window is
partially open. To reduce the sound,
open another window or the sunroof
(if equipped).
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.
Uplevel Shown, Base Similar
The driver door also has switches
that control the passenger and
rear windows. The power windows
work with the ignition in ACC/
ACCESSORY, ON/RUN or when
Retained Accessory Power (RAP)
is active. See Retained Accessory
Power (RAP) on page 9‑20.
Press the switch to lower the
window. Pull up on the front edge of

3-30 Seats and Restraints
{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 has 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. You can lock the doors, and turn off
the interior lamps and hazard
warning flashers by using the
controls for those features.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑20 andEvent Data
Recorders on page 13‑21.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
