While enjoying my new car on the first mountain trip, got a message: "Please take a rest".

I was just practicing some features like dynamic cruise control and lane departure warning. Took by surprise.

Did you, folks know what may trigger this message? Don't remember any mention of it in owners manual

 

Car thought you were falling asleep? Perhaps your tests of the DCC and LDW systems were too realistic :-)

 

Maybe it was your doctor calling...

 

Under the information section of the display behind the steering wheel on the 2016 ES, there is one screen that say something like coffee break or rest break. I think it is linked wit the amount of time the car has been driven without a "pit stop."

This may be why you got the message. I checked the Owner's Manual and there is no mention of this screen, but it is there.

 

Is this screen only in vehicles with the LDW system or all 2016 models? Because if it is only in the vehicles with the LDW system then if the system detects frequent departures from the lane without the turn signal then it could suggest that the driver rest a bit. Drifting from lanes is a good indicator of a drowsy driver.

 

We just finished a 900mile drive in our new '16 and the message popped up twice.
It appears to be time related.
If you bring up the information screen between the one in the instrument cluster not the nav screen,
The tire pressure screen will be 1st item
scroll down 1 and you'll see the "Time To Rest" right under the Sway Warning
The blue line will run down, turn yellow and then give you the Take a rest message.
It appears after about 2 1/5 hours

 

Since the trip was about 1 hour and 45 minutes one way I would guess that frequent lane departures while practicing LDW triggered that message.

I am waiting on Lexus response and keep you all posted.

 

On the other hand:

We just did 900 miles (15hrs with stops) in 2 days in our new '16.
We finished with 1111miles on the odo, what are the odds of that.
This is an extremely comfortable car to drive, we've had just about every incantation of the ES, '91 ES250, '94 ES 300 (still in use in FL with my mother), '02 ES300, '10 ES350 and now this '16.
They all have been great on the road, the '91 and '94 had the best road/sport feel. the '02 and '10 were comfortable but the road feel was sacrificed.

This '16, in "SPORT" mode, we got tired of eco and normal real fast, was a pleasure to drive. The feedback to the driver was great, the new Enform makes it easier to keep your eyes on the road when streaming I may actually subscribe after the free year. It is not the equivalent of my IS-F or Boxster, but for a "Boulevard Cruiser" this is a fantastic car.

 

Yep, this is my second Lexus. Previous was 2002 ES300. We decommissioned it with 175000 miles after many trips all over Utah, Arizona, New Mexico, Montana, etc. Great car, but new one even better

 

As I've promised, here is Lexus response: "The "Please take a rest" is the vehicle reading of the driver swaying. The system activates due to the vehicle going over the traffic lane which reads the driver may be tired therefore rest is recommended. The Lane Departure Warning (LDW), when activated, displays this message."

Now we know

Thanks to all for the replies. Happy driving!
