The door out of the temple is blocked by a tree!

You need a tool to help you here.

The driver of the jeep out on the runway might have some tools.

But you need him to come closer.

Did you look at the back of his jeep?

The code "C5" is painted on it.

You may have seen something else that uses similar codes.

Have you checked the trees in the clearing of the jungle yet?

There's a parachute in the tree to the left of the monkey.  Reel it in, and
get the walkie talkie that's there.

Enter the code "C5" into the radio -- turn it on with the button on the
bottom, and then use the switches above the letter and number to set it to
C5.

Then just press the big button, and the jeep will move close to Alaniz's
shack.

Search the jeep to get a tire iron and a jack.

Now you can use those two items to move the tree.
