Setting The Time - Chevrolet 2007 TrailBlazer Owner's Manua

Notice: Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer/retailer.
Also, check federal rules covering mobile radio
and telephone units. If sound equipment can
be added, it is 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.
Notice: The chime signals related to safety
belts, parking brake, and other functions
of your vehicle operate through the radio/
entertainment system. If that equipment
is replaced or additional equipment is added
to your vehicle, the chimes may not work.
Make sure that replacement or additional
equipment is compatible with your vehicle
before installing it. See Accessories and
Modifications on page 386.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition is
turned off. See Retained Accessory Power (RAP)
on page 113 for more information.

Setting the Time

The radio may have a button marked with
an H or HR to represent hours and an M or MN
to represent minutes.
Press and hold the hour button until the correct
hour displays. AM or PM displays for morning
or evening hours. Press and hold the minute
button until the correct minute displays. The
time can be set with the ignition on or off.

buttons at the same time until UPDATED and the
clock symbol appear on the display. If the time

take a few minutes for the time to update.
