Starting And Operating; New Vehicle Break-In; Using Heavier Suspension - GMC 2011 Yukon Denali Owner's Manual

9-28 Driving and Operating

Using heavier suspension

components to get added
durability might not change your
weight ratings. Ask your dealer
to help you load your vehicle the
right way.
If you put things inside
your vehicle like suitcases,
tools, packages, or anything
else they go as fast as the
vehicle goes. If you have to stop
or turn quickly, or if there is a
crash, they'll keep going.
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.
WARNING (Continued)
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.

information for off-road driving in

New Vehicle Break-In

The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
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.
