Normal Mode Grade Braking
If equipped with a gasoline engine
and an automatic transmission,
Normal Mode Grade Braking is
enabled when the vehicle is started,
but is not enabled in Range
Selection Mode. It assists in
maintaining desired vehicle speeds
when driving on downhill grades by
using the engine and transmission
to slow the vehicle. The first time
the system engages for each
ignition key cycle, a DIC message
will be displayed. See

Did you get a truck with eAssist? Engine shutoff at stops, regenerative braking, etc?

Not that I know of. I will need to look at my sales sign the thing they post on the window.


I'll check tomorrow since I left my truck at home today.

See below this is what mine does when I am going down a small hill.


For grade braking to activate it requires the driver to apply steady brake pedal pressure to maintain desired speed while driving on a downhill grade. The vehicle's modules monitor the amount of brake pedal apply, vehicle deceleration rates, and other factors to determine if normal mode powertrain grade braking is necessary. When the feature activates for the first time that ignition cycle, the DIC will display "Grade Braking On" or "Grade Braking Active" and you will notice the transmission down shifts and engine RPM increases. At this point, if the brake pedal is released the transmission will hold the current gear. If additional engine/transmission braking is needed to help maintain desired speed, reapply steady brake pedal pressure and additional down shifts may occur.

So the tow light is not on when the grade braking comes on.


But the above mentioned that I posted does sound like what it is doing especially last night. I guess I am excited and nervous to drive my truck to Yosemite on Sunday.


Now I just found out that my dad's suburban which he doesn't drive as much needs new brakes and new tires. The new tires he is going to buy when this week when he get his oil changed but the brakes I am worried about. I guess I will be staying close to my parents in the suburban driving down to Yosemite.

It's her thread. She derailed this one without our intervention.

Nope. He won't pay for those tires. Besides he will not need those since the Suburban just sits in the driveway most of the time.


I am going to buy those tires for my truck and not tell them.
