Tailgate
I.

You can open the tailgate by lifting up on its handle while pulli\
ng the tailgate
toward you.
To shut the tailgate, firmly push it away from you into the latch.
When you put the tailgate back up, pull it back towards you,
to be sure it
latches securely.
Quick-Release Tailgate

If you have a quick-release tailgate it can be removed by:
1. Raising the tailgate slightly and removing both retaining cables.
2. Lift the tailgate at the right side and pull it out at the left side.
Reverse the above procedure to reinstall. Make sure the tailgate is secure.
Then
Vehicle theft is a big business, especially in some cities. Although your
vehicle has a number of theft deterrent features, we know that nothing we
put on it can make it impossible to steal. However, there are ways you can
help.
Key in the Ignition: If you walk away from your vehicle with the keys inside,
it’s an easy target for joy riders or professional thieves-so don’t do it. When
you park your vehicle and open the driver’s door, you’ll hear a tone reminding
you to remove your key from the ignition and take it with you. Always do
this. Your steering wheel will be locked, and
so will your ignition. If you have
an automatic transmission, taking your key out also locks your \
transmission.
And remember to lock the doors.
Parking at Night: Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight. Put them in a storage
area, or take them with you.
Parking Lots: If you park in a lot where someone will be watching your vehicle\
,
it’s best to lock it up and take your keys. But what
if you have to leave your
ignition key? What
if you have to leave something valuable in your vehicle?
Put your valuables in a storage area or console.
Lock the console.
Lock all doors except the driver’s,
Then take the door key with you.

Service & Appearance Care
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause the lock to bind. De-icers which contain alcohol
could also wash away the lubricant,
so be sure to lubricate the lock after
using a de-icer of this type.
Tailgate Handle
The tailgate handle pivot points on your vehicle should be lub\
ricated to keep
it working smoothly.
Your maintenance schedule will tell you how often to lubricate the handle.
See “Recommended Fluids and Lubricants” in the Index for the proper
lubricant to use.
Electrical System
Battery
Every new GM vehicle has a Delco Freedom@ battery. You never have to
add water to one of these. When it’s time for a new battery, we recomme\
nd
a Delco Freedom@ battery. Get one that has the catalog number \
shown on
the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
I - Batteries have acid that can burn you and gas that can explod\
e. You I
1 can be badly hurt if you aren’t careful. See “Jump Starting” in the
Index for tips on working around a battery without getting hur\
t.
Contact your dealer to learn how to prepare your vehicle for longer periods.
Bulb Replacement
Before you replace any bulbs, be sure that all the lights are off and the
engine isn’t running.
