Chevrolet Silverado 1500 2023 Owner's Manual page 394

Front Position
4. If the flat tire is on the front of the
vehicle, position the jack under the
bracket attached to the vehicle's frame,
behind the flat tire, as shown.
Rear Position
5. If the flat tire is on the rear, position the
jack under the rear axle about 5 cm
(2 in) inboard of the shock absorber
bracket.
Warning
Getting under a vehicle when it is lifted
on a jack is dangerous. If the vehicle slips
off the jack, you could be badly injured
or killed. Never get under a vehicle when
it is supported only by a jack.
Vehicle Care
Warning
Raising the vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall. To
help avoid personal injury and vehicle
damage, be sure to fit the jack lift head
into the proper location before raising
the vehicle.
Warning
The jack has a feature to limit its travel
to prevent overextension. When the
height limit is reached, an increase in
resistance if felt when attempting to
raise the jack farther. Raising the jack
past the height limit can damage the jack
pin and cause the jack to lock into an
overextended position or not lower fully.
Do not attempt to force the jack higher
once the height limit is reached.
6. Turn the wheel wrench clockwise to raise
the vehicle. Raise the vehicle far enough
off the ground so there is enough room
for the spare tire to fit under the
wheel well.
