Tailgate
You can open the tailgate by pulling up on the handle
while pulling the tailgate down.
When you put the tailgate back up, be sure it
latches securely.
Follow these steps if you want to remove the tailgate:
1. Raise the tailgate slightly.
2. Remove both retaining
cables. To remove each
cable, turn it so the end
faces the front. Then,
push forward so the
larger part of the hole is
over the bolt. Pull the
end over the bolt.
3. With the tailgate halfway down, pull the tailgate
toward you at the left side and then move the tailgate
to the left to release the right side.
Reverse the procedure to reinstall. Make sure the
tailgate is secure.
Theft
Vehicle theft is 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.

the lamp assembly near
the tailgate latch.

Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see ªWiper Blades,
Cleaningº in the Index.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. (See ªRecommended Fluids and Lubricantsº in
the Index.)
Manual Transmission Check
Check the transmission fluid level; add if needed. See
ªManual Transmission Fluidº in the Index. Check for
leaks. A fluid loss may indicate a problem. Have the
system inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
ªAutomatic Transmission Fluidº in the Index. A fluid
loss may indicate a problem. Check the system and
repair if needed.Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
ªHydraulic Clutch Fluidº in the Index. A fluid loss in
this system could indicate a problem. Have the system
inspected and repaired at once.
