Starting And Operating Your Vehicle - GMC 2003 Sonoma Owner's Manual

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:
Ignition Positions
With the key in the ignition, you can turn
it
to five
different positions.
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.
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.
