It means all wheel drive
I want to add a transmission anti-slip additive to my 2008Cadillac SRX4 AWD 3.6 but can't find even a trans dip stick to check the fluid level? I've been told that's where you add any extra fluid or trans additive? This car is new to me and its not quite the same of vehicle I'm used too? Can you give me some help? Thanks, Bob
A Cadillac SRX (or any sedan for that matter) with a 4 subscript means it is an AWD model. SRX. 2004-2010 models were either RWD or AWD while 2011-present models are either FWD or AWD (designated by the 4 subscript on the rear model badge).
