In my 2010 the jack was under the back seat. I lifted my seats up in 2015 and there's just a storage area on one side and power inveter on the other. Without looking at the manual I figured you guys would know.

Also there is straps behind each head rest in the back seat. What are those for?

 

On the screw its behind the rear passenger side seat back. There is a pull tab that releases the seat back. The straps are for child seats.

 

Passenger side seat back about 8" down pull the fabric loop and bingo. Use it for jacking up your arm and grabbing the manual.

 

I jacked my arm up and now I can reach the glove box!!

 

OP doesn't know jack.

 

That's jacked up.

 

"Without looking at the manual I figured you guys would know"

That's your problem right there... kinda sad world we live in when it is (seems?) faster to go to a web forum, post a new thread, wait for someone to chime in to get your answer rather than just opening an owner's manual...

 

To see the spare tire proceed to back of truck.
Get on knees.
Put head almost to the ground.
Now look up under the bottom of said truck.
Its the round black thing.

 

(owner's manual) Don't have one -OR- would like a digital, searchable desktop document?.

 

Don't drive your truck when you're all jacked up.
