but heating ok after a couple of miles have owend 4 petrol toyotas did not take as long to warm up

The diesel is a large lump of an engine and will take a while to heat up this time of the year :)

Oh, and welcome :)

Hi and welcome to the club

Welcome also to the pleasures of winter motoring in a diesel.

Your experience is quite normal. The heater is electrically assisted to counteract the time it takes for the engine to generate adequate heat

You will also notice that the revs go up to about 1200rpm to compensate for the additional electrical load created by all the other heat generating stuff you have switched on - rear window heater, heated seats, lights etc.

Enjoy your RAV [especially if you have snow ]

Concur with Davrav...all to do with the efficiency of your slower igniting diesel by compression, rather than the explosion of a petrol cylinder due to the electrical spark from a plug. Totally normal, mildly annoying as it is.

Wife's 3 door warms up in no time.

Big Kev....and welcome....

thanks for the info did notice rpm go up on tick over when fan on for heater than go back to 750 rpm when warmed up

found that when driveing on hard packed snow on roads not much brakeing effect when going down inclines

It's all about the tyres.

Another YouTube video for the forum.

Edit: and

(and why you should put the winter tyres on all four wheels instead of just two).

Winter tyres will make a big difference but don't expect a 4WD to be much different from a 2WD in terms of braking and sliding; its greater capability lies in forward traction. In fact, a 4WD can be worse once it starts to slide because of its greater weight, although I think the difference is marginal. The trick is not to drive more boldly because you have the extra confidence of a 4WD - just drive very carefully as you normally would in snow and ice, and you'll be quite safe (as long as the other road users take the same approach, of course!).

4 wheels better in snow than 2 wheels, but on ice there is little to be gained having 4 wheels. so ive read in a article on winter driving.

some 4 wheel vehicles have crawler gears for hill descending,very handy,but as usefull as a chocolate teapot once you start slinding on a ice covered hill.

Thanks Acetip,

Just given a pratical demostration of driving on ice to my wife and an owner of a Ford Focus. Ford Focus driver decides to pull out to overtake a stationary car despite a Bright Green RAV 4.1 coming the other way, which has right of way, lots of ABS action from both cars, with the Ford Focus slewing all over the road the forward momentum/weight of the RAV kept in in a staight line. Decided better course of action and route would be to try and steer towards some virgin snow to get some traction and re-applying brakes just before we pass through the hedge and into a Rhyne (Water filled drainage ditch), finally stopped 4" from the edge. Fortunately no damage to the RAV thank heavens for the plastic side trim, hedge not looking so good, a nasty smell coming from the Focus driver.

Moral of the tale, it doesn't matter what you are driving 2wd or 4wd when you are on ice,just dont change speed or direction unless you want smelly underpants!!!

Sounds like you did well to avoid him
