Chevrolet 2010 Avalanche, Owner'S Manual, Page: 205 / 582

Cargo Area Floor Drains
The cargo net has cut outs for the four cargo-area floor
drains located under the cargo mat near the sides of the
cargo area.
Periodically flush the drains through the cut outs to
clear debris and allow water to drain from the cargo
area. If the cargo area is extremely dirty lift up the
edges of the cargo floor mat or take the whole mat out
and flush the drains with water.
Top-Box Storage
The vehicle has top-box storage units on both sides of
the vehicle. The passenger side top box contains the
tools needed to change a flat tire.
Use the key to unlock or lock it. Press the key cylinder
button and swing the lid open. Turn on the cargo lamps,
if the vehicle has them, to light the inside of the cargo
area. See
Exterior Cargo Lamps on page 4 ‑ 13 for
more information.
