Hello all, I'm new to Lexus having owned numerous Volvos for the past 35 years. We have just taken delivery of a new Lexus GS450H. We're very pleased with it but I've found that the user manuals (both the large 'online' - circa 600 page and the paper version supplied with the car) are not too good.There are two issues I am stuck with at present:
1) The light switch(es) - the left hand stalk has two rotary knobs - the outer is the normal light selector (as far as I can tell) and there is an 'inner' rotary knob with three positions - the first two have detents and the switch locks in one of these two positions, the last position (three) has no detent and the knob returns to two when the knob is released. Neither manual mentions this knob or shows it in any illustration - what is its function? There is also a push button near the driver window side of the dash with a headlight symbol worded 'Auto', again, what is its function? I cannot find out how to switch on the rear high-intensity foglight either - this too is not mentioned anywhere.
2) I'm used to the (very useful) speed limit detection system - my last Volvo had it and it was very reliable. The system on the Lexus seems less dependable and often fails to detect roadsigns. When it does it then seems to stop displaying this information at random (this also occurs in the HUD). I've also noticed that when the vehicle is stopped and parked-up, upon returning to the car the speed limit display shows nothing and will only re-display after it has 'seen' a valid speed limit sign - this seems rather strange as if there's a speed limit when the car is parked-up and left, then the same limit will surely apply when returning to the car and starting-up. Any comments please?
Regards,
Mark Woodward.
