Storing the Roof Panels
Warning
In a collision, sudden stop, or other
maneuver, an improperly stored roof
panel could cause personal injury or
vehicle damage. Always use the stowage
system provided and follow stowage
instructions.
Use stowage bags for each roof panel. Never
store the roof panels outdoors and
uncovered.
You may also stow just the front row of
panels.
The included Roof Panel Stowage System is
only meant for short trips over paved roads.
This system is not sufficient for protection
of the roof panels during off-roading. For
off-road protection please see the Accessory
Hummer EV Roof Panel Stowage Kit.
To put into stowage:
1. Shift the vehicle into P (Park).
2. Turn the vehicle off and set the parking
brake.
3. Open the hood and retrieve the four roof
panel stowage bags, removing them
from the vehicle completely.
4. Open the first roof panel bag, and place
inside the eTrunk , with the handles
facing the front of the vehicle and the
Hummer EV logo on top.
5. Place panel into bag with weatherstrip
side facing toward rear of vehicle.
6. Close bag with the zipper, ensure zipper
is fully closed.
7. Repeat Steps 4-6 for each additional roof
panel, placing each bag on top of the
last bag. This can be done for just the
front row of roof panels, or all four roof
panels.
8. Install the two retention straps from rear
cargo hook to front cargo hook, being
careful to ensure straps are holding
down bags.
