The 2006 Jeep Commander uses ATF+4 power steering fluid.
In detail, the Commander’s hydraulic power steering system requires the ATF+4 specification. Using Dexron II/III or other fluids can degrade seals, cause noise, and lead to leaks, so you should verify the cap labeling and the owner’s manual before topping up or changing fluid.
Recommended fluid type
The official guidance from Jeep/Chrysler for the 2006 Commander specifies ATF+4 for the power steering system. Use Mopar ATF+4 or any ATF+4 fluid that meets Chrysler MS 9602 specification to ensure compatibility and sealing integrity.
Below are the recommended options and cautions when selecting power steering fluid for the Commander.
- Mopar ATF+4 (preferred)
- Other brands’ ATF+4 fluids that meet Chrysler MS 9602 specification
Always ensure the product label states ATF+4 and that it is appropriate for Chrysler/Jeep applications. When in doubt, ask a dealer or check the cap on the reservoir for the required specification.
How to check and top up or replace the fluid
Before performing any checks, ensure you are using the correct ATF+4 and take care to avoid spills. Below is a step-by-step guide to checking and topping up the power steering fluid, and to performing a basic fluid change if needed.
- Park on level ground, engine off, and set the parking brake. For a more accurate reading, check the level when the engine is cold.
- Open the hood and locate the power steering reservoir. Remove the cap and wipe the dipstick or sight marks clean.
- Check the fluid level. If it is below the minimum mark, add ATF+4 until it reaches the full mark. Use a clean funnel to prevent contamination. Do not overfill.
- If the fluid appears dark, burnt, or smells off, consider a full system flush and replacement rather than just topping up. A professional service may be recommended to avoid air and foaming in the lines.
- After topping up, reinstall the cap and start the engine. With the engine idling, turn the steering wheel from lock to lock several times to bleed air in the system. Recheck the level and top up if needed.
- Take a short test drive and listen for any unusual noises; recheck the level once the fluid has circulated.
If you’re not comfortable performing this yourself, a trained mechanic or Jeep service center can handle it safely and correctly.
Summary
For a 2006 Jeep Commander, use ATF+4 power steering fluid, preferably Mopar ATF+4 or any ATF+4 that meets Chrysler MS 9602 specification. Check the reservoir cap and the owner's manual to confirm. Regular checks help prevent steering issues and seal damage, and a proper flush is best left to professionals if the fluid is old or contaminated.

Does it matter what power steering fluid I put in?
So it is absolutely critical that you match the power steering fluid with the application. Some may use a different weight of oil, and if you use the wrong power steering fluid, it can change the feel of the steering, but most of all, it can damage the pump and the rack on the vehicle.
