When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.
SeeCharging System Light 0149
for more information. The voltmeter
gauge may also read lower when in
fuel economy mode. This is normal.
Readings outside the normal
operating range can also occur
when a large number of electrical
accessories are operating in the
vehicle and the engine is left idling
for an extended period. This
condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the vehicle must be driven, turn off all
accessories, such as the radio and
air conditioner and unplug all
chargers and accessories.
Readings outside the normal
operating range indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.

Organize the phone book and
contact lists clearly and delete duplicate or rarely used entries.
If possible, program speed dial
or other shortcuts.
. Review the controls and
operation of the infotainment
system.
. Pair cell phone(s) to the vehicle.
The system may not work with
all cell phones. See “Pairing”in

dialing capability, learn to use
that feature to access the
address book or contact list.
. See “Deleting a Bluetooth
Device” in this section.
{Warning
