The 2006 Nissan Quest S is a moderately difficult vehicle to maintain and will require many tools in order to complete many of the more difficult repairs. You will need to use many tools in order to remove the tail light housing for access to the bulb. The tools necessary may not be readily available for a repair. The cabin air filter is extremely difficult to access. You will have to remove the glove box housing, remove many screws, and make a tough reach to complete. The center brake light can be difficult to access, as you will have to use a few tools to peel back a panel.
Some things are easier on the 2006 Nissan Quest S. Checking the transmission fluid level with reliability is no problem, as the dipstick is easily accessible in the engine bay. Not every model includes this dipstick. The engine air filter is easy to access and change, as you only have to disengage a few fasteners for access and these fasteners are easy to disengage. The power steering reservoir is easily visible in the engine bay. This will make it easy to check the fluid level.
