Some H3 questions on details

[DWPC]

I drove an H3 on SUnday and was impressed, but the dealer is 35 miles away and I've come up with some questions on things that didn't occur to me while there:
<UL TYPE=SQUARE>1. Does the automatic trans have a "sport" mode allowing you to shift up or down by just flicking the shift lever (vs. selecting a gear)?
2. I see some posts here about tire pressure monitoring, but the H3 literature doesn't mention it. Is it available?
3. If there are any AZ drivers around, how's the AC adequacy on 100F+ days? Any signs of engine overheating when idling in traffic?
4. Is the power loss at higher elevations very dramatic; e.g., 5000 feet?
5. Can any other GM dealers do warranty work on Hummers? Its a long way to the Hummer deale and it looks like loaners are not provided.
6. It appears GM doesn't include towing or roadside service in the warranty. Right?[/list]
