Remote Start time

MikeNH · December 1, 2013

That's weird. Even on the coldest of days mine will be ready to go in a couple cycles of the remote start.

Yeah, I think I might have a bad thermostat. I've never had a vehicle take this long to warm up.

When its above 15 degs one cycle is all I need I also keep my heat on the auto setting that turn the blower on full blast till you insert the key

Looking through the manual it states when remote starting the vehicle it remembers the previous settings. This may take some experimenting but what if you tried some different settings like activing the recirculation mode, manual mode opposed to auto, or possibly closing some of the vents in the dash with the thumb wheel. I learned something looking for this too. It states the rear redefroster will activate when its cold enough but the light does not come on during remote start. Hope this helps.

This won't work with the Auto-start but i noticed in the manual their is a fast idle option in the manual on page 9-28. I would think a faster idle would warm it up faster.

I added a Viper 2-way paging alarm and I'm able to adjust the run time. I only have mine set for 12 min because that is all I usually need. I'm not sure what the maximum time allowed is but when I first got it, it was set for 15 min

I'm finding this remote start to be better than on my old '07 Yukon...

The one difference is that the Yukon would be 'warm' when I got in after two cycles, while the Sierra really isn't all that warm just getting in...BUT the second you turn the key there is a lot of hot air ready for you if you want it...the Yukon never had hot air ready.

The Sierra does fog up more during remote start, especially with snow on the windshield, but I have some RainX Fog wipes I'm going to try.

I'll also say this, the fob remote start has a hell of a lot more range than in my old Yukon.

I noticed this myself, I actually use my IPhone app more than the key fob.

Pretty sweet feature. Too bad you can't do it remotely.

Fast Idle System

If equipped, this feature is available only with cruise control. The manual fast idle switch is operated using the cruise control buttons on the left side of the steering wheel.

This system can be used to increase engine idle speed whenever the following conditions are met:

. The parking brake is set.

. The brake pedal is not pressed.

. The vehicle must not be moving and the accelerator must not be pressed.

To enable the Fast Idle System:

. Press and release the cruise control on/off button and ensure that the switch indicator light is lit.

. Press and release the cruise control SET- button. Engine speed will be held at approximately 1200 rpm.

When the fast idle is active, the Driver Information Center (DIC) will display FAST IDLE ON.

When the fast idle is active, the Driver Information Center (DIC) will display FAST IDLE ON.

For those that are interested the diesels have the 'fast idle' and also an 'elevated idle'.

Elevated Idle

The engine has a cold temperature high idle feature which elevates the engine idle speed from base idle

to 1050 rpm for pickup models or 1200 rpm for van models when outside temperatures are below 0°C

(32°F), and the engine coolant temperature is below 65°C (150°F). This feature enhances heater

performance by raising the engine coolant temperature faster.

This feature can be turned on or off using the DIC buttons. If the vehicle is not equipped with DIC buttons, do

the following to turn this feature on or off:

1. Turn the ignition to ON/RUN, with the vehicle off.

2. Press the accelerator pedal to the floor and hold while quickly pressing the brake

pedal three times in less than eight seconds.

3. Release the accelerator pedal and start the engine.

When the engine is started, it will slowly ramp up to the high idle speed after a delay of a few

seconds up to approximately two minutes. For this method to work properly there must be no

throttle or brake pedal faults.

The engine idle speed will return to normal once the following conditions are met:

Once engine coolant temperature reaches 65°C (150°F).

Air intake temperature reaches0°C (32°F).

The high idle speed will be temporarily interrupted and the

engine speed will return to normal if any of the following conditions ccur:

The brake pedal is applied.

The accelerator pedal is pressed.

The transmission is shifted out of P (Park) or N (Neutral).

Vehicle speed is detected.

Once these inputs are removed, the engine idle speed will slowly ramp back up to high idle after the normal

delay, if the conditions for engine coolant temperature and air intake temperature are still met.

I use the OnStar app a bit too, but mainly because of the novelty of starting my truck with my phone... My ramp is across from my office building and down the block, with my old truck I had to walk down the hall to conference room to get close enough, now I can do it without leaving my desk... Quicker than having to go through to the app, punch in my my pin, hit 'ok' to 'only use remote start where legal & safe' prompt (which I don't get, is remote start not legal in all states?)...

Just easier, though not as cool, to use the fob. Best use I know of for the app is when you're flying back home in the winter and you can start your truck from the tarmac or terminal.

Awwwww, I just checked & my truck doesn't have it. Anyone else try?

Wonder if it's only for work & fleet vehicles (since they often use high idle to run accessories/equipment off truck's power?)

Probably only the 2500/3500's.
