Cruse Control

Dandytf

Only used Cruise Control very few times whilst driving my 2011 Clio.

Found it fun and very efficient easily changing pre set speed from 70-60 or 50.

Does cruise control add ware to break pads/discs.

I maybe incorrect, would like to use Cruise Control more often.

Only if you set it at 70 when allthe other traffic is doing 50

No it doesn't.

Well not on a Clio which has very basic cruise control. On other vehicles with adaptive cruise control, where brakes are applied to slow the vehicle, there might be a small extra wear on the brake pad/discs but so small to be negligible.

The only thing with cruise control, is DO NOT use it in the wet or on frosty roads. If the wheels start to lose grip, the car won't understand what's happening and might start applying the throttle at the wrong time.

No blasted point having it in this country then

which is why I commented 70-60-50

Thanks, I'll avoid using for a few weeks yet then.

Excellent point, I didn't consider road conditions.

That's just a myth, it doesn't work like that. The cruise control will keep the wheels spinning at a constant rpm that equates the to target road speed set. If the car starts to aquaplane/skid the actual speed of the vehicle might reduce slightly but as far as the car is concerned if the wheels are still spinning at the same RPM the computer won't be aware of any speed reduction. If the wheels start to spin faster because of the lack of traction this will be interpreted by the system as a speed increase and the throttle will back off to bring the wheel RPM back down to the target range.

The XF and XJ are very hard on rear brakes, but I think that is not just due to Cruise Control using the rear brakes to control speed but because the traction control does and they are fitted with a speed limiter which also does. Often under 20k miles!

Don't know much about the Clio system though, but I wonder if most current vehicles fitted with stability control and traction control aswell as Cruise Control may be a little harder on brakes than with older less sophisticated cars?

And probably born of the stories from the US:

my car accelerated when I hit the water and took off

What was it, an F14?

Remember these are the people that had to be told not to use cruise control on an RV while making a cup of tea in the back, told not to try and dry their pets in a microwave and are the reason we have 'Contents may be hot' warnings on a McDonalds coffee cup.
