  • Crawl Control - Tested (questions)

    Hi All,

    So I took the Kakadu out for its first off-road venture, nothing major, just an easy stroll through Mt Mee (Dayboro to Woodford). The purpose of the trip of course was to test out its 4x4 features, overall i'm quite impressed. I had a few questions, hopefully someone knowledgeable out there can help.

    - I do not have the DAC switch in the Kakadu, am I correct in assuming that Crawl Control replaces the need for DAC as it essentially serves the same purpose?
    - This is my first Automatic 4x4, in typical easy trails (such as in Mt Mee) where you have long winding downhill tracks - how do you guys typically manage speed without using the brakes too much? Today using S mode and picking between gears (4-hi) I couldn't really find a gear to maintain a reasonable speed...without having to slow right down and keep it in first, and don't want to resort to 4-lo when the terrain doesn't really call for it. Is this just something I need to get used to, perhaps try a different driving technique? I really tried to limit the brake usage today, but a lot of the time had no choice unless I was on steep hills and in 4-lo..and the brake pads started to smell at one stage so I pulled over for a while and cooled them down.
    - I tried a few 'moderately' steep inclines/declines today to try and test out crawl control. Scared the life outta me, and i'm not sure if I'm switching it on correctly or if it is normal. Going by the offroad manual that came with the kakadu, it does mention to expect sounds coming from the wheels, etc. However this was loud crunching and could feel it in the pedals. Has anyone tried this yet (crawl control)? I did exactly as described in the manual "Was in 4-lo, S-1st (manual says to pick any gear), switched it on and selected slow speed". The instant I select it and it's activitated, off she goes but along with it all the noises and the crunching feeling in the pedals. So I instantly turn it off.... hoping someone can shed some light on this one!

    That aside, I think I'm going to have a blast with this vehicle. Looking forward to the ARB bars coming out, suspension lift, and a decent set of All Terrains!

    Not sure if it is the same as the DAC in the 120 I have. That also makes a lot of noise but works well on Steep descents. The noise is the brakes cycling on and of in rapid succession.

      I have seen a video review on a 200 series, it was pointed out that it sounds awful when CRAWL is turned on but that it means that it is working.

      The DVD was one from a 2007 Action 4x4 and was across two disks (different reviews) both time it was mentioned to be loud and sounded like the car was busted or something.

      Hope this helps, off course I would advise that you check with your dealer if you are still concerned.

      Regards

        Thanks Simba, I might go look up some 200 series reviews, that sounds spot on though. It's quite an awful sound and feeling, I immediately turned it off! Anyhow, i'll check with the dealer too and if all is good i'll test it out again on some serious hill climbs.

          Hey Mojotec,
          God awful noises coming from the brake systems are part and part of the crawl system when activated. It is basically the brakes via the abs system grabbing and releasing the disc rapidly to keep you at the desired speed. You can adjust the speed to go up a level. This will make the brakes apply less but will still be very noisy! Also, when stopping I have found it is better to turn the crawl off first and than apply the brakes. I was always coming to a very jerky halt when deactivating crawl by pressing the brake pedal. It will also pay to read the manual to confirm what lights should be on when the system is active. It can be a little worrying to see the dash lit up like a christmas tree with all the warning lights because TRC, ABS etc has been taken over by the CRAWL.
          Cheers,

            I have a VX 200 Series Cruiser. Its CRAWL also makes god-awful noises and the manual advises that "noises" are normal.

            In the 200 (only available in an auto trans) the manual recommends low 2nd for up hill and low 1st for downhill. It works well, and I'd assume there are similarities in the systems between marques.
            Patrol's are great vehicles. Pity about Nissan.

              The clunking / thumping noises, whatever you want to call it, is perfectly normal.

              My Land Rover '99 Discovery Series II with Hill Descent Control makes the same sort of noises. Was pretty unnerving the first time I heard it too! :roll:

              I haven't tried it yet on my Cruiser but I'd be expecting the same.

                I had the same experience. A lot of noise whilst using Crawl Control but the dealer assured me it means its doing its job and the noises are normal.

                The hill wasn't anything extreme but the crawl control woked very well.
