AWD continuously?

Does anyone leave their Traverse in AWD year-round? I'm used to SUVs where you don't have to manually switch between 2WD and AWD.

The owner's manual states:

"AWD may turn off and display a message on the DIC in instances of extensive use or overheating."

Is this a warning not to leave it in AWD continuously? Aside from fuel economy differences, I'm wondering if we can just leave it in AWD continuously.

Here's my guess


I doubt it is a warning.....probably only in AWD vehicles with 2WD as an option to prevent novices from seizing of the engine due to overheating. There is no temperature sensor in the rear axle so it obviously feeds off excessive engine and transaxle temperatures. Difference being that AWD vehicles without the ability to convert to 2WD must remain in AWD even when the engine is overheating, but the AWD/2WD switchable vehicles can disconnect the additional engine load of the rear axle in an attempt to lower engine temperatures to a safe limit. No sense putting a notification message in a full time AWD since they are SOL and lack the ability to freewheel the rear axle to reduce engine/transaxle loading. And running full time AWD in an AWD/2WD you will never get the notification message under normal operating conditions.



Something akin to a comparing a cargo plane to a passenger plane in a situation desperately in need of additional altitude sufficient to clear a mountain range.....the cargo plane has the ability to dump the cargo and reduce loading to safely complete the trip, but the passenger plane is SOL.

I only use AWD in the winter when the roads are snow covered or during the other seasons when it rains and there is a possibility of hydroplaning.

I also use it once in a while if I drive off-road; which hasn't happened too often.

You save a bit on fuel and slightly less wear & tear on the rear wheel drive components.

But that's just me.

Forgot to mention that with the Traverse, you can switch between 2WD and AWD on the fly. No need to stop or place the vehicle in park when switching between the two.

Much better than the old days, whatever those were...

Same goes for shifting from D to L or vice versa which can be done on the fly at any speed without damage. You may think you control gear shifting- you don't - the ECU does. Labeling L (instead of M for manual without a clutch pedal) is an old carryover from previous transmission mechanical linkage days. Possibly done on purpose by designers/engineers in order to keep consistency between gens of a particular model or more likely not to confuse novice drivers. But, they didn't seem to have that problem with the Silverados with fly by wire trannys which no longer use L but instead do use correct lettering, M, not L, for Manual control.


Most times I don't start in L9 to defeat start/stop - only 3 traffic lights on the 25 miles to the next town and the vehicle is still in open loop for the first two of them so s/s is not yet active. But if going to an area where I want to defeat s/s by shifting to L9, I'll do it on the fly (and without being stopped and pressing "+" button 8 times) just by simply shifting from D to L while at cruising speed in 9th gear, e.g. at around 60 mph, simply drop the shift lever form D to L and you're in L9 in, and remain in, full auto operation. When shifting from D to L at any speed the tranny will place the it in Lx, x being whatever gear the vehicle is in at the time of the lever is shifted to L and it will be the maximum gear it will attain in automatic mode unless modified by pressing the "+" or "-" button or until shifted back to D.


If climbing a hill, I'll sometimes shift to L for laughs just to see what gear the ECU has selected, eg. L4, and then shift back to D. Same goes for crawling in stop and go traffic, place in L2 and no more s/s and as traffic picks up shift back to D.

Wonder if that message is useful when towing, reminding people get it out of AWD and put it in Tow mode AWD which has the towing gearing programed to reduce issues they mentioning.

So what models have a selective 4 wheel/AWD to 2 wheel drive? I have 2017 and it's totally automatic. I thought all Traverses where.



I can explain it, but I can't make you understand it!
Everything should have a like button!

No. AWD Gen 1s are full time AWD ...they automatically distrubute power between axles through a slush box, but to not have a switchable transfer case to lock out and free wheel the rear axle. Only AWD Gen2s have a driver controlled wheel selector that manually switches from AWD to 2WD to lock out the rear axle entirely and the DIC contains active wheel display showing a graphic of which wheels are active.
