Starting And Operating; New Vehicle Break-In - GMC 2010 Acadia Owner's Manual

WARNING
Things you put inside your
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
Put things in the cargo
area of your vehicle. Try to
spread the weight evenly.
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
Do not leave an
unsecured child restraint
in your vehicle.
When you carry something
inside the vehicle, secure
it whenever you can.
Do not leave a seat folded
down unless you need to.

New Vehicle Break-In

Notice: The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
If you have all-wheel drive,
keep your speed at 88 km/h
(55 mph) or less for the first
805 km (500 miles).
Do not drive at any one
constant speed, fast or
slow, for the first 805 km
(500 miles). Do not make
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
Driving and Operating
Avoid making hard stops for
the first 322 km (200 miles) or
so. During this time the new
brake linings are not 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.
Do not tow a trailer during
break-in. See Driving
Characteristics and Towing
Tips on page 9 48 for the
trailer towing capabilities
of your vehicle and more
information.
Following break in, engine speed
and load can be gradually
increased.
