Voice Mail Calling
To learn how to access your voice mail, refer to “Working
with Automated Systems”.
Working with Automated Systems
This method is used in instances where one generally has
to press numbers on the mobile phone keypad while
navigating through an automated telephone system.
You can use your Uconnect™ Phone to access a voice mail
system or an automated service, such as a paging service or
automated customer service line. Some services require
immediate response selection. In some instances, that may
be too quick for use of the Uconnect™ Phone.
When calling a number with your Uconnect™ Phone that
normally requires you to enter in a touch-tone sequence
on your mobile phone keypad, you can press the button and say the sequence you wish to enter,
followed by the word “Send”. For example, if required to
enter your PIN followed with a pound, ( 3746#),you
can press the button and say, “ 3746# Send”.
Saying a number, or sequence of numbers, followed by
“Send”, is also to be used for navigating through an
automated customer service center menu structure, and
to leave a number on a pager.
You can also send stored Uconnect™ Phonebook entries
as tones for fast and easy access to voice mail and pager
entries. To use this feature, dial the number you wish to
call and then press the button and say, “Send”. The
system will prompt you to enter the name or number and
say the name of the phonebook entry you wish to send.
The Uconnect™ Phone will then send the corresponding
phone number associated with the phonebook entry, as
tones over the phone. 3 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 131

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position.
2. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN, and remain
on briefly as a bulb check. If the light stays on or comes
on while driving, turn off some of the vehicle’s non-
essential electrical devices or increase engine speed (if at
idle). If the charging system light remains on, it means
that the vehicle is experiencing a problem with the
charging system. Obtain SERVICE IMMEDIATELY. See
an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”. 3. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
4. Low Fuel Warning Light
When the fuel level reaches approximately 2.8 gal
(10.6L) this light will turn on and a single chime
will sound.
5. Speedometer
Indicates vehicle speed.
6. Front Axle Lock Indicator — If Equipped
Indicates when the front axle lock has been
activated.300 UNDERSTANDING YOUR INSTRUMENT PANEL

11. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE: The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. (Continued)302 UNDERSTANDING YOUR INSTRUMENT PANEL

13. Air Bag Warning Light
This light will turn on for four to eight seconds

16. Coolant Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on while driving, safely pull over
and stop the vehicle. If the A/C system is on, turn it off.
Also, shift the transmission into NEUTRAL and idle the
vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service.
NOTE: As the coolant temperature gauge approaches
 H,  this indicator will illuminate and a single chime will
sound. Further overheating will cause the temperature304 UNDERSTANDING YOUR INSTRUMENT PANEL

gauge to pass  H.  In this case, a continuous chime will
sound, until the engine is allowed to cool or the 4 minutes
duration is expired, whichever come first.
17. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
18. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range. CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to (Continued)
