Front Parking assist

[awh3rgm]

Just got my 2020 Denali Monday and while parking i noticed that i don't heard any beeps when approaching an obstacle until the bar turns red then it starts to beep and loud. Shouldn't it beep faster as you approach and object? I checked the alert settings and it is set to beep. Could there be another setting?

Rear gives a beep on first detection.  Front does not. 

 

The 'really close' Beeps happen sooner or rear than front. (1 ft front, 1.5 foot rear) 

 

Presumably because it's easier to tell how close to stuff you are in front vs rear. 

 

Park Assist
With Front and Rear Park Assist, as the vehicle moves at speeds of less than 8 km/h (5 mph) the sensors on the bumpers may detect objects up to

1.2m (4 ft) in front and

2.5 m (8 ft) behind the vehicle

within a zone 25 cm (10 in) high off the ground and below bumper level. 

 

The instrument cluster may have a Park Assist display with bars that show “distance to object” and object location information for the Front and Rear Park Assist system. As the object gets closer, more bars light up and the bars change color from yellow to amber to red.

When an object is first detected in the rear, one beep will be heard  from the rear, or both sides of the Safety Alert Seat will pulse two times.

 

When an object is very close
—<0.4m (1.5 ft) in the vehicle rear
or <0.3m (1 ft) in the vehicle front—
a continuous beep will sound from the rear or front depending on object location,

or both sides of the Safety Alert Seat will pulse five times.

Beeps for FPA are higher pitched than for RPA. 

 

 

My 18 works the same way.

 

No front beeps until it is 'very close'.

iirc, the closest bar is lit on the dic when the beeps occur.

Great thank you Redwngr for responding, so it appears to be working correctly then, my Tundra would beep slowly going forward or backward, i just took it for granted that they all did that. Thank you for the explanation, much appreciated. I love the truck, the handling, the power, the feel, its just worlds over my tundra. I am somewhat disappointing in the way it was delivered, door panels and door sills scratched up, fender scratched from wiping it off with a dirty towel, I'm sure if i press the issue they will fix it.

My  2019 Silverado park assist kept blocking when I shift into Reverse . It works in morning when I leave then get to work I’ll shift into Reverse it blocks right away. This didn’t start happening until they did the Battery cable recall and the electric brake recall and the brake pad wear recall. I took it back in my sensor has a chip on it they this is what caused it said it wasn’t covered under road hazard warranty 420 Dollars to fix only 15000 miles on it not Happy.

wow, $420 to replace a snap in sensor that costs alittle over $100......they don't even have to remove anything to get to it, just unplug it, snap the old one out and snap the new one in, less than 5 mins in labor time........must have charged you for trouble shooting your problem.....bummer
