Caution
Always replace the battery with
the correct type. Replacing the
battery with an incorrect type
could potentially create a risk of
battery explosion. Dispose of
used batteries according to
instructions and local laws. Do
not attempt to burn, crush, or cut
the used battery.
Replace the battery if the DIC
indicates that battery replacement is
necessary.
The battery is not rechargeable. To
replace the battery: 1. Press the button on the RKE transmitter to extend the key
blade.
2. Remove the battery cover byprying it with a finger.
3. Remove the battery by pushing on the battery and sliding it

battery down until it is held in
place. Replace with a CR2032
or equivalent battery.
5. Snap the battery cover back on to the transmitter.
Remote Vehicle Start
If equipped, this feature allows the
engine to be started from outside
the vehicle.
/:This button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear window
defogger may come on during a
remote start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start.
If the vehicle has heated and/or
ventilated seats, they may come on
during a remote start. See Heated
and Ventilated Front Seats 040.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
require a person using remote start
to have the vehicle in view. Check
local regulations for any
requirements.

Lighting Features
Entry Lighting
Some exterior lamps and most of
the interior lamps turn on briefly at
night or in areas with limited lighting
when the Remote Keyless Entry
(RKE) transmitter
Kbutton is
pressed. See Remote Keyless Entry
(RKE) System Operation 08. After
about 30 seconds the exterior lamps
turn off, then the dome lamps and
remaining interior lamps dim to off.
Entry lighting can be disabled
manually by turning the ignition on
or to ACC/ACCESSORY, or by
pressing
Qon the RKE transmitter.
This feature can be changed. See
Vehicle Personalization 0113.
Exit Lighting
Some exterior lamps and interior
lights come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes
on after the ignition is turned off. The exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization
0113.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.

134 Climate Controls
Climate Control Influence on Fuel
Economy
The climate control system is
dependent upon other vehicle
systems for heat and power input.
Certain climate control settings can
lead to higher fuel usage.
The following climate control
settings use more fuel:
.Comfort air conditioning mode
. Defrost mode
. Extreme temperature settings,
such as 15 °C (60 °F) or 32 °C
(90 °F)
. High fan speed settings
To help reduce fuel usage:
. Use the full automatic control as
described under “Automatic
Operation.”
. Use eco air conditioning, instead
of the comfort air conditioning.
. Select a temperature setting that
is higher in hot weather and
lower in cold weather. .
Turn off the air conditioning
when it is not needed.
. Only use defrost when needed
to clear the windows.
Automatic Operation
The system automatically heats or
cools the vehicle to the desired
temperature:
. Fan Speed
. Air Delivery Mode
. Air Conditioning
. Recirculation
When AUTO is lit, all four functions

setting is displayed. Functions not
manually set will continue to be
automatically controlled, even if the
AUTO indicator is not lit.
For automatic operation: 1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Then
adjust the temperature as
needed for best comfort. To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather.

on when automatically controlled.
Press
hto manually select
recirculation; press it again to select
outside air.
