Replying to: rollbar (Dec 11, 2006 6:03 am) Water should not come in the doors and I've not heard any reports of water filling the exhaust. Not sure of the technical explanation but it hasn't been a problem. Thanks, Scott scott |

This link has some information that may be helpful for others who are confused, (as I am). Apparently I'm not the only one, the manual is vague and confusing and the systems overlap somewhat.

Replying to: rollbar (Dec 11, 2006 6:21 am) VSC VSC works with the electronic throttle control system (ETCS-i) and the ABS actuator system, measuring relative wheel speeds plus vehicle yaw and steering wheel position to determine whether a dangerous condition exists, Understeer (pushing) or oversteer ("fishtailing") can both result in accidents. Should VSC sense a problem, the system will reduce engine power and apply braking to one or more wheels to try to regain control and a proper line through the corner. Note: VSC is not a substitute for safe driving! Trac TRAC senses wheelspin in slippery conditions and reduces engine power to the wheels to help regain traction, and can apply braking to regain traction and control. The electronic limited slip system works on the rear axle, only, using the brake system without reducing engine power, giving better off road performance than TRAC by allowing the vehicle to maintain a higher speed in loose soil or sand. Technical Comments Like VSC, TRAC works with the electronic throttle control system and the ABS system, reducing engine power and applying braking to the spinning wheel or wheels (rear, only on 2WD vehicles, front and/or rear on 4WD vehicles) to regain traction and/or send power across the open front or rear differential to a wheel with better traction. Engaging the electronic limited slip system (Auto LSD) overrides the reduction in engine power if wheels slip, and provides a limited slip function to the rear differential only. Auto LSD Auto LSD uses brake pressure to slow a slipping wheel and send power back across the rear differential to the other wheel, providing traction. Technical Information TRAC functions in much the same way, but reduces engine power to regain grip, and can apply brake pressure to one wheel to send power across the differential. Button activated, Auto LSD allows the vehicle to accelerate normally while providing traction to both wheels. Rear Diff lock locks the rear axles together, so if one wheel moves the other wheel moves so you don't lose power in off road situations and get stuck. You would only use it off road and would be only below around 15mph VCS helps when you are cornering and traction control is more for driving straight line

Replying to: dreasdad (Dec 12, 2006 5:04 pm) Very helpful. I read a comment somewhere in a forum that the automatic should not be driven in 4H at speeds over 50 to 55 mph or for long periods of time. That seems counter intuitive to me. Certainly you wouldn't drive long distances or highway speeds in 4L but I thought that was what 4H was for? Thoughts? Thanks again.... Roll

Replying to: rollbar (Dec 13, 2006 6:59 am) The Mechanical reason is that the drive shaft can bind over time, thats why the 6 speed manaul full time 4wd has a center limited slip diff |

Might save a few bucks if you do: "The base 2007 FJ Cruiser, which is equipped with a 239-horsepower 4.0-liter V6, gets a base price increase of $200 for a bottom line of $22,755, including a $645 destination charge." Toyota Hikes Prices on 2007 Models (Inside Line) |

Is there anyone who posts here with inside knowledge of Toyota? I would love to see a factory sunroof for the FJ. Do we know if one is in the works? |

Replying to: rollbar (Dec 11, 2006 6:21 am) The locking rear dif -- RR Dif Lock -- is for use only when you have a spinning wheel. If you try to use it for driving you'll discover that you have very little steering control. Before you activate it make sure the wheel has stopped spinning. Turn it off as soon as you're unstuck. |
