Statements in the owner's manual would have me renting a truck for towing.
An additional transmission cooler would help but I don't have enough faith in the CVT transmission to use this vehicle for towing.

. When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
. When driving uphill in hot weather, pay
attention to the coolant temperature high
warning light (for all models) and AT OIL
TEMP warning light (for AT and CVT
models) because the engine and transmission
are relatively prone to overheating
under these conditions. If the coolant
temperature high warning light and/or the
AT OIL TEMP warning light illuminates,
immediately turn off the air conditioner and
stop the vehicle in the nearest safe
