Driving lamps & automatic driving

Jun 14th, 2004, 16:06

I've just bought my first ever Volvo (an S80se, 2001, 170bhp) and wondered if anyone could advise on the following:

1. Is it possible to disable the driving lamps that stay on all the time even in the brightest summer sunshine?

2. When I'm stationary, say in a queue at traffic lights, should I knock the car out of drive into neutral or is it OK to just apply the handbrake and leave it in drive?

Thanks

1. Yes, but you need to get a dealer to do it via VADIS. I recommend you keep them on.

2. Shift to neutral uinless only a brief stop. This will reduce wear on the torque convertor, and is safer in case your foot slips of the brake.

Also it helps save petrol.

What wear?

There's just a bit of fluid being spun. It'll generate some heat, that's all.

If it's a stop like in a traffic jam, I'd agree - you don't want that heat build up.

But for longevity, it's likely to be better keeping it in drive. The current thinking being that there is more wear and tear likely from having the transmission go to neutral, then engage a gear again, than from simply generating a little heat.

Handbrake.

How so?

Is the idle _that_ much higher, when in drive?

True, the engine is under more load, so possible more fuelling - but to be honest, it's got to be pretty darned marginal.

My S80 is the same type and vintage as yours, Kevan, and goes into neutral automatically when the vehicle comes to a stop and your foot remains on the footbrake, re-engaging drive when the footbrake is released. This feature has been removed from S80's circa 2003 onwards but, if yours is the five speed auto, should be on yours. Check your handbook if in doubt.

Enjoy the car.
