Anyone else notice the brake momentarily engages when you are backing up on an incline? (from a stop) I haven't noticed it going forwards on an incline. I assume this feature is to prevent clutch slippage? Maybe this isn't unique to the 13, my 08 didn't didn't have it though. (At least I hope it's a feature and not an issue.)
Clutch question
- Thread starter RSH427R
- Start date
It is a feature called "hill assistance" or something like that. It is to prevent you from rolling backwards when starting forward on an incline.
Mine don't do that you push in clutch on a hill and your rollin, ?
Backing on an incline huh, have to try...
that hill assist feature is not on the GT500, only the V6 and GT models. Not sure what to make of this the OP is describing
It's on mine :shrug: Never experienced anything like it. As you can see below I have a steep driveway. It's done it every time.

I stand corrected then, I had heard it was not on the GT500....oh well cool then I guess, not that I ever felt like I needed it! but thanx!
It's all good. Cool feature when your driveway is a 45 degree angle or you're launching a boat with your stang!! :beer:
Chevy dealer explained this to me about hill assist. Chevy has it in their Equinox, etc.
Only activated on very steep hill, varies car by car due to sensor tolerance.
You have to be on the brakes hard, then as you give it gas, the car momentailily holds the brake on for a limited time to reduce rolling back as the throttle is applied.
In old days you just needed to be a bit quick with the feet.

This is straight from the owners guide!
Hill Start Assist
This feature makes it easier to pull away when the vehicle is on a slope without the need to use the parking brake. When this feature is active, the vehicle will remain stationary on the slope for two to three seconds after you release the brake pedal. This allows you time to move your foot from the brake to the accelerator pedal. The brakes are released automatically once the engine has developed sufficient drive to prevent the vehicle from rolling down the slope. This is an advantage when pulling away on a slope, (for example from a car park ramp, traffic lights or when reversing uphill into a parking space).
This feature is activated automatically on any slope that can result in significant vehicle rollback. This feature will not operate if the parking brake is activated.
Using Hill Start Assist
Note: If the engine is revved excessively, hill start assist will be deactivated.
1. Press the brake pedal to bring the vehicle to a complete standstill. Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will remain on the slope without rolling away for approximately two or three seconds. This hold time will automatically be extended if you are in the process of driving off.
4. Drive off in the normal manner. The brakes will be released automatically.
Disabling and Enabling the Hill Start Assist Feature
Your vehicle comes with hill start assist already enabled. If desired, you can disable the feature by following the procedure below.
The following procedure must be completed within 45 seconds or the process will have to be repeated. Begin this procedure with the ignition turned off. This procedure is for both disabling and enabling the hill start assist system.
1. Apply parking brake to make sure the vehicle is not moving.
2. Turn the ignition on.
3. Place the vehicle in neutral gear.
4. Slowly press and release the brake pedal five times – make sure the brake pedal is completely released each time.
5. Rotate the steering wheel at least one full turn to the right and return
the steering wheel to the original starting position.
6. Rotate the steering wheel at least one full turn to the left and return the steering wheel to the original starting position.
7. Slowly press and release the brake pedal five times – ensure the brake pedal is completely released each time.
When the procedure has been completed successfully the ABS icon in the instrument cluster will flash:
• three times indicating that the feature has been disabled. • twice indicating it has been enabled.
Once the feature is programmed as desired, it will remain in that mode until the above procedure is repeated.
Note: When the AdvanceTrac system is disabled (see the Traction Control chapter in your Owner’s Manual for information on how to do this), the hill start assist feature is also disabled for the duration that the AdvanceTrac system is in that mode. Re-enabling AdvanceTrac will also re-enable hill start assist.
Note: If you have used the above procedure to disable the hill start assist feature, then enabling or disabling AdvanceTrac will not effect the hill start assist system.

I've never had hill assist on any of my past nor current vehicles - all are manual trannys. But I am in NY where it's pretty much all flat. But in a couple of months (I hope) I will be picking up my 2013 GT500 in San Fran. That shall be THE place to test this safety feature! Hahaha.
It works even on the slightest incline, I tested it tonight, good margin of safety for the wife.
