The 1997 Pontiac Bonneville SE is a moderately easy vehicle to maintain, but is more recommended to those capable of vehicle maintenance. 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. Changing the center brake light is easy to do, as you only have to reach through the trunk for access. The brake fluid reservoir is easily visible in the engine bay. This will allow you to check and replenish the fluid level on a regular basis.
Some things are problematic on the 1997 Pontiac Bonneville SE. You will have to remove a large panel from under the vehicle for access to the petcock. This will require you to contend with gravity as you complete. While some of the tail light bulbs are easy to change, the others are extremely difficult to access. These bulbs will require many tools. You will have to follow extra steps to raise your wiper blade, and use a tool to complete.
