Smart Cruise control

[vega]

Let's say you are set to 50 mph. This is indicated in the center of your instrument cluster as the digits 50. Tapping it once brings the new speed set up to 51 and naturally the car accelerates to accomodate the new speed. On the other hand, if you would have tapped it 5 times it would have been set to 55. Here's your problem, holding it for more than 1 second will cause it to increase 10 fold as in jumping from 50 to 60, keep holding and it will jump to 70 etc. According to the way you say it is supposed to work, it sounds like you inadvertently set it to 10 or 20 or more miles per hour over what you were initially set at so naturally it feels like it is accelerating until you apply the brakes. The + button is not an accelerate button, it is a speed set increase button and also serves as a resume to speed button if you needed to slow down using the brakes.

To increase cruise control set
speed:
Follow either of these procedures:
• Push the RES+ switch and hold it.Your
vehicle set speed will increase by 10
km/h or 5 mph. Release the switch at
the speed you want.
• Push the RES+ switch and release it
immediately. The cruising speed will
increase by 1.0 mph (1.6 km/h) each
time the RES+ switch is operated in
this manner.
• You can set the speed to 113 mph (180
km/h).

To decrease the cruising speed:
Follow either of these procedures:
• Push the SET- switch and hold it. Your
vehicle set speed will decrease by 5
mph or 10 km/h. Release the switch at
the speed you want.
• Push the SET- switch and release it
immediately. The cruising speed will
decrease by 1.0 mph (1.6 km/h) each
time the SET- switch is operated in this
manner.
• You can set the speed 18.6 mph (30
km/h).
In both instances it states to hold the button until you reach the desired speed, then release at the speed you want. In either direction my car will accelerate / decelerate until the cruise kicks out, @ 10mph and 113mph.

The single press works perfectly, up or down 1mph.

But every other cruise system I have ever had does not do endless acceleration unless you continue to hold the resume button down. Resume on other systems typically does 2 functions, first brings you back to your originally set speed, second if held down will accelerate the car to whatever speed you desire and releasing the buttons et the new cruise speed. The Genesis system is not the same. Not clever.

Hey, you got to get with the times, can't live in the past.

Yes, you are correct the standard systems will accelerate until you let go and this will be your new set speed. Also works the same on deceleration. The smart system gives you read out setting which you change and the car adjusts itself to the new setting. Resume works the same as standard systems

Here are 2 scenarios.

Basic system...Driving in a 65 mpg zone on cruise and come up on a 55 mph zone. hold - button until car reduces speed to 55 on the speedometer and now let go. Car continues at this new speed

Smart cruise..... Hold - button down and after 2 seconds the 65 indicated will change to 55 and now let go. Car will decelerate to new set speed and remain there.

Tapping the button will decrease by factor of 1 therefor to reduce the speed by 5 mph, tap 5 times to set indicated cruise speed and let the car do the rest.

Once you get used to it I think you will agree it is a much better way of doing it. Just the 30+ years of habit make for a slightly longer learning curve.

In a nutshell, you are saying to watch the cruise speed display on the dash to set the speed up or down, not the speedometer.

Yep.

thanks, I'll give it a try this afternoon .........

Has anyone pressed and held the RES + button for more than 1 second? The car is supposed to accelerate until the button is released, mine continues accelerating until I hit the brake. The SET - button does the same thing, will keep slowing until I brake or turn the cruise control off. Its definitely not right. The single press works correct up or down, and the Smart Cruise Control works properly. I'll have to take it back in again, the original ESC module failed on delivery, resulting in the cruise not working, now the new unit seems to malfunction.

RES = Resume (it's also incremental increases in set speed)... meaning tap it once and it will resume the last recorded set cruise speed.

One of my attractions in looking at moving from my Prius to a Genesis is ACC. I find the Prius to be a very tiring car to drive on trips more than 2 hours. I'm sure this is due to many other things besides lack of ACC such as quality of seats, size of engine, etc.

I like to get everyone thoughts on if they feel that ACC reduces both fatigue and stress when driving longer distances more than 2 hours. Do you use it on short distances as well or mainly highway driving.

I like it and use it quite a bit. It would be even better if it wasn't so abrupt at slowing down when it perceives a vehicle too close as previously mentioned.

Thanks Midnightsun, works as advertised. To clarify for others, do not wait for the car to reach the desired speed to release the + button, watch the center cruise display and release the + button when the display reaches your desired speed.

On my car the firsa option does not work the way described in the manual. The speed copntinues until I either manually shut-off SCC or hit the brake to disengage SCC.

When you press the RES+ button, watch the display between the speedometer and the tach, you should see the set speed increasing by 1mph. If you hold it, the set speed will increase in increments of 10mph. My mistake was to watch the speedometer and release the button when the car was at the speed I wanted, when I should have watched the set speed display, and release the button when it reached the speed I wanted.

Well what I think he was asking is, how do you turn off the "adaptive" portion of the cruise control, and this was something that I too wondered when I first took delivery of my car (I've since changed my tune).

Me too (on both accounts). The "smart" part is even smarter than I first thought. For example, suppose you're set at 75 mph and following a 70 mph car at one of the 3 selectable distances, while you wait for the left lane to clear so you can pass the car in front. A car passes you in the left lane going 75+, clearing the lane, so you swing out to pass. Even though you may be closer to the car that just passed you than the pre-set following distance, the SCC senses that the other car is going faster than you are, and it does not slow you down to maintain the distance. Your car just keeps accelerating up to 75. (By the time you get to 75, the distance to the car that passed you is probably OK.) Nice.

There is a situation where it would be nice to be able to switch off the "smart" feature and resort to normal CC, I've discovered. We were traveling the PA Turnpike in a very curvy section with concrete barriers quite close to both edges of the road. Even with the SCC set at the minimum

How do you set the distance on the smart cruise control?

 

[MrB0462]

How do you set the distance on the smart cruise control?

There is a button on the right side of the steering wheel, it has a car icon with 2/3 lines underneath. It only works when the SCC is active. There are 3pre-set distances. If you watch the dash display you will see the distance change each time you press the button.

From personal experience I would not reduce the default setting. Also keep in mind that if the car in front of you comes to a complete stop your vehicle will also come to a rolling stop, BUT you then need to apply the brakes to come complete to a full stop.

Thanks for your reply....I have my car almost six (6) months...never realized you can set the distance on SCC....Thanks again!!

Do all Priuses lack ACC, or just the model you have?

I use CC whenever I get out on the highway. It definitely makes cruising more comfortable and pleasurable, and much less tiring and stressful on long trips. The Genesis SCC does so to an even greater degree, in my experience.

 

[jkohn]

Toyota probably just figures that nobody who does lots of long trips and highway driving would be crazy enough to buy a Prius, unless they're just a masochist in which case the lack of ACC could be seen as a positive.

For me, cruise control of any variety is like sunroofs - I've had both on many cars, not by choice, and I have never used either.

 

[dg_moore]

For that matter, I have a Go-Phone for emergencies but I don't turn it on - when I renewed my minutes this year I found I had used it twice in the previous 12 months. That comes to about $50 per call, but I like to have the phone in case I land upside down in a ditch or run out of gas or something...
I'm by no means a technophobe - I'm a senior software system designer by profession - but most of this stuff just doesn't interest me

 

[Genesiswannabee]

Well I guess I must be a masochist having put 135,000 miles on my Prius since 2004. The long trip I have gone on was a college road trip with my daughter that was about 1500 miles...Prior to my Prius I had a Jaguar XJ6.

Now I'm fine with the Prius around town but on the highway above 60 the bumps and road noise affect me.

My version of the Prius does not have ACC.
