Do you ever use the driving modes on your Yukon?....Sport, Off-Road..

[Baja_Bob]

Does anyone ever use the drive modes like the sport, tow, off-road? I played around with the sport mode recently and didn't notice much difference in engine noise or performance. How much do they actually do?

I’ve never used that dial in my ‘21 Tahoe and I’ve had it for about a year.

I’ll use the tow haul mode when my boat is behind me. I’ll use off road the last 10 miles of minimum maintenance road into my fishing spot in Canada this summer, the added 2” of ground clearance will be helpful.

Your need to use these other modes will depend on usage. If you never leave the pavement and don’t tow, you won’t need them.

Tow/Haul in my ‘13 was really nice to have with the boat on, especially when defending hills…probably added 25% to the life of the brakes because it held a lower gear.

Basically, the driving modes adjust the transmission shifting points based upon the activity. For example , in sport mode it shifts at higher RPM. Normal will shift at lower RPMs to conserve fuel. I wasn’t aware it shifted ride height unless you are equipped with air suspension and then maybe it adjust that as well.

Yes, ride height adjustment happens if equipped w/ the air suspension.

Ive used tow mode more often than the others. Tow mode helps coming on a downhill heavy with adjusting the shift points to minimize excessive brake wear. Sport mode, maybe twice when I was feeling “froggy”.

Tow mode for sure, makes a huge difference in how the vehicle performs when dragging around a trailer. Can't comment on sport or off road, will probably never use either

I haven't tried it yet, does off-road mode have any effect in 2WD, does it shift to 4WD?

I've used sport mode once or twice just to see what it was about. In most vehicles this usually tightens the suspension, changes shift points (as mentioned above) and tightens the power steering. Any idea if this is true for the Yukon (besides the shift point changes)? Seat of the pants made me feel the suspension was tighter in sport but not sure if that's true. I use tow haul when towing of course and it makes a huge difference, however, sometimes it just hangs in low gear for way longer than my liking so I have to manually intervene to get it to shift into a higher gear to help with mileage.

It's been a while since I towed anything, last time I used tow/haul the button was on the end of the shift lever, does tow/sport prevent cylinder deactivation?
