2003 GMC SONOMA windshield wipers

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle doesn’t need an elaborate
“break-in.”But it will perform better in the long run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the first 500 miles (805 km).
•Don’t drive at any one speed — fast or slow — for
the first 500 miles (805 km). Don’t make
full-throttle starts.
•Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new brake
linings aren’t yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
•Don’t tow a trailer during break-in.
See “Towing a Trailer” in the Index for
more information.
Ignition Positions
With the key in the ignition, you can turn it tofive
different positions.
Notice:Don’t operate accessories in the
ACCESSORY position for long periods of time.
Prolonged operation of accessories in the
ACCESSORY position could drain your battery and
prevent you from starting your vehicle.
A (ACCESSORY):This position lets you use things like
the radio and the windshield wipers when the engine
is off. Push in the key and turn it toward you. Your
steering wheel will remain locked, just as it was before
you inserted the key.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
Windshield Wipers
Windshield Washer
Cruise Control (If Equipped)
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
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 isnished, the lever will return
automatically.
An arrow on the
instrument panel cluster
willash in the direction of
the turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
don’tash but just stay on, a signal bulb may be burned
out and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check the fuse (seeFuses and Circuit Breakers
on page 5-89) and for burned-out bulbs.

Windshield Wipers
N
WIPER:Turn the band with this symbol on it to
operate the windshield wipers.
MIST:Turn the band to MIST for a single wiping cycle.
Hold it until the windshield wipers start. Then let it
go. The windshield wipers will stop after one wipe. If
you want more wipes, hold the band on MIST longer.
OFF:Turn the band to OFF to turn off the windshield
wipers.
LO (Low Speed):Turn the band away from you to
LO and past the delay settings for steady wiping at
low speed.
HI (High Speed):Turn the band away from you,
to HI, and past the delay settings for wiping steady at
high speed.
Delayed Wiping:You can set the wiper speed for a
long or short delay between wipes. Turn the band
to choose the delay time. The closer to LO, the shorter
the delay.Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
Windshield Washer
J
PUSH:Use this paddle to spray washeruid on the
windshield. The wipers will clear the window and then
either stop or return to your preset speed.
{CAUTION:
In freezing weather, don’t use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.
