2008 HUMMER H3 Owner ManualM

Turn and Lane-Change Signals
The turn signal has one upward (for right) and
one downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever will automatically
return to the off position.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the change is
completed. The lever will return by itself when released.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers will not see your
vehicle’s turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when signaling
a turn, check for a burned-out bulb or a blown fuse.
For bulb replacement, seeTaillamps, Turn Signal,
Stoplamps and Back-up Lamps on page 5-50. For a
blown fuse or circuit breaker, seeFuses and Circuit
Breakers on page 5-102
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL will also appear
in the DIC. To turn the chime and message off, move
the turn signal lever to the off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 3-43DIC Warnings and Messages
for more information.

Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. Because you’re a good
deal longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
