Ect Snow Button

[sami_remote]

I noticed a button called "ECT Snow" next to my gear box today. Does anyone know what this button is for?

Thanks,

Sami

dont no ive got one too push it and see :D

It's

ECT PWR

and

SNOW

Basically, the ECT is like a "sports" button on AUTO's .... just holds the revs out a bit longer ...... and keeps gear in for longer before it changes.

SNOW is the opposite, it kills the "kick down" feature in an auto .... so if ICY/SNOW wheather conditions are apparent, you can't 'kick down' and lose control.

I was just about to post RTFM ;)

It retards the car's performance to prevent wheel spinning etc during slippery conditions...... something the southerners need by the bucket full judging by every time we get a frost in Surrey and the number of cars I see abandoned or with big dents in on the way to work ;)

I noticed yet another button on my gearbox call "Shift lock". Does anyone know what this one does? :duh:

Its if your in park and unable to start (brokedown) then you can press shift lock so you can put it into "N" to move it.

Which series RX do you have?

SNOW mode, as people have said, alters the transmission shift pattern. Shifts up earlier, shifts down later etc to prevent wheelspin etc.

If you have a vehicle equiped with an electronic throttle (series II only, not series I) then it also makes the throttle less sensitive.

I have the 2005 model (series 2).

Does it matter if you have it on all the time? does it consume more fuel in this mode?

I also saw a few postings up that there is a way to put the RX in "sports ECT" mode so that it does the opposite. How is this done? I can only see one button saying ECT Snow?

[ColinBarber]

You can have it on all the time if you wish although you lose a bit of performance. I use it sometimes in stop/start traffic which makes it easier to drive smoother.

Not 100% sure on the RX series II but snow mode is normally reset when the engine is turned off, so you would have to press the button every time you used the vehicle if you wanted to keep it on all the time.

It doesn't use more fuel, possibly a bit less as you tend not to drive so hard.

The other posting about sports ECT mode are general posting and not specifically about the RX. The IS, GS and even import RX300 have this power mode. The UK RX300s do not have this.

All these questions................ does nobody read there manual?

[trinilex]

They are good questions...............Someone stole my manual.........

ECT SNOW on the Rx 300.

ECT = Electronically Controlled Transmission.

SNOW = For driving in potentially slippery / snow / icing conditions.

Press this button when driving in above conditions to reduce the onset if inadvertant wheel spin.

It desensitises the throttle pedal and also prevents the Rx from selecting first gear as it will force the gearbox to pull away from standstill using second gear.

Can be used all the time and will not increase fuel consumption as it purely manages the gear changes and throttle sensetivity.

Incidently, using this mode is the only way to prevent the gearbox lurching from slow speed starts, (see other threads), so it is useful if driving in slow spped traffic conditions.

Hope this helps

RxMike.

14 years later ... looked at this button as I drove home tonight..

Interesting.

I found a (push push) button today that I haven't seen before but perhaps not surprising as it is hidden by the flap of the the glove box of the RX.  If anybody does not know what it's for, it stops the hatch from being operated by the key fob,

That's another thing I've learnt (and will probably forget).

Also seems to do something to the rear diff when slowing down to prevent the car from spinning out. Used it in thick snow a couple of years ago and was amazed by the difference it made, even on crap tyres the car felt planted!!!

 

Press the button, witchcraft and wizardry happened and the car transformed into a go anywhere beast!!
