Trans Hot Idle Engine; Audio System(S); Turn Signal On - GMC 2004 Sierra 1500 Pickup Owner's Manual

TRANS HOT IDLE ENGINE

(Allison Transmission
If the transmission fluid in the vehicle gets hot, this
message will appear on the DIC, and you will hear a
chime. The chime will stop when the transmission fluid
temperature is less that 265°F (129°C). Driving with
the transmission fluid temperature high can cause
damage to the vehicle. Stop the vehicle and let it idle to
allow the transmission to cool. This message will
clear when the fluid temperature reaches a safe level.
Notice: If you drive your vehicle while the
transmission fluid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission fluid or while transmission
temperature warning is displayed.

TURN SIGNAL ON

If a turn signal is left on for 3/4 of a mile (1.2 km), this
message will appear on the display and you will
hear a chime. Move the turn signal/multifunction lever to
the off position. Press the select button to acknowledge
the message and clear it from the DIC display.

Audio System(s)

Notice: Before you add any sound equipment to
your vehicle – like a tape player, CB radio, mobile
telephone or two-way radio – be sure you can
add what you want. If you can, it's very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle's engine,
radio or other systems, and even damage them.
Your vehicle's systems may interfere with the
operation of sound equipment that has been added
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it first. Figure out which radio you have in your vehicle,
find out what your audio system can do and how to
operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, you can play your
audio system even after the ignition is turned off.
See "Retained Accessory Power (RAP)" under Ignition
Positions on page 2-22 .
