So yesterday I was able to try out engine braking for the first real time - I was coming down a local mountain road (paved), and in D it was just accelerating. Even when I went into S it was the same... I believe I eventually tried going to S-2 but at that point the RPM went up above 4.5k and I didn't keep it there, went to D and used brakes but I smelled some burning smell?
I feel like my first trial of this concept didn't go so well...
An excerpt from this trucker website, primarily for big rig drivers, but applicable to all heavy vehicles like the 4Runner. I bolded some of the text:
Safety Tips for Driving on Hills | fleetanswers.com
Tips for Approaching Hills
The approach is often where accidents and mistakes happen, because driver's expect problems when coming down the hill, not coming up. Keep these tips in mind:
* Watch for signage - Hills with hazards, like falling rocks or deceptive grades, will have signage that indicate their characteristics. When approaching a hill, watch for this type of signage, and heed it.
*
Slow down - Do not speed up to try to get up the hill. Slow down, especially as you approach the top of the hill. Towards the top, the contour of the road will make it difficult to see, so going too quickly will make risks even more hazardous.
* Prepare for surprises - As you approach a hill, know that you are going to face surprises. Start being more aware, so any animal, vehicle, or road obstruction doesn't turn into a catastrophe.
* Note the weather - Wet or icy roads can make it more challenging to get up the hill, so note the weather as you approach.
* Prepare for less visibility - The surprising risk of hills is the fact that you can't see what's coming. Be prepared for limited visibility as you approach the crest.
* Yield to downhill travelers - If on a narrow road or other situation where someone must yield to oncoming traffic, always yield to the downhill vehicle, which will have trouble stopping.
Tips for the Descent
When you descend the hill, you need some additional tips. Consider these:
* Slow down - The hill will cause some natural speed increases, so slow down to avoid speeding too quickly. Also, it's difficult to stop on a hill, so a slower speed is wise.
* Downshift - Running at a lower gear will help hold you back so you don't get going too fast. This will also help reduce wear and tear on your breaks.
Use brakes wisely - Use brakes wisely to maintain a safe speed, but avoid situations where you need to stop suddenly on a hill, if possible.”
