Toyota 4Runner Shift-Leather Transfer Case Okay, so you're into driving to that secret trail high into nowhere's bill. And suddenly you're in the big bad boulders. No problemo. Say hello to the Shift-Leather Transfer Case. Am I talking to you? Hop in. Let me tell you all about it. The 4Runner Trail Grade has a lever to shift the transfer case between two wheel drive high, four wheel drive high, and four wheel drive low ranges. You can shift from H2 to H4 while driving at speeds less than 50 miles per hour. To shift from H4 to L4 or L4 to H4, you must come to a complete stop and continue to press the brake pedal. Shift the transmission into neutral gear. Move the shift lever into L4 or H4 position. Then shift the transmission into either a forward or reverse gear. Note that when your 4Runners in H4 or L4 mode, a four wheel drive icon will be illuminated on the instrument panel. Oh yeah, it's that easy. Now you're off to explore points unknown to anybody, but you, your 4Runner, and a bald eagle. Toyota, let's go places.
