How much can a Lexus RX 300 tow?
The Lexus RX 300 can tow up to 3,500 pounds when equipped with the factory towing package; without that package, the typical capacity is around 2,000 pounds. Always verify your exact figure from the vehicle’s label and manual, as ratings vary by year and drivetrain.
What determines the RX 300's tow rating
The official towing capacity is driven by equipment and engineering: engine cooling, transmission, brakes, hitch, and electrical wiring. The RX 300’s early models used a 3.0-liter V6; towing capacity is sensitive to whether the car has a dedicated towing package that includes an upgraded radiator, transmission cooler, hitch, and wiring harness. Only vehicles with this package are typically rated for the top 3,500 pounds. Without it, the rating is lower and more sensitive to year and drivetrain.
Typical capacities by setup
Below are common figures reported across model years, highlighting the distinction between factory-towed and non-towed configurations.
- Factory towing package: up to 3,500 pounds (1,588 kg), depending on the exact year and drivetrain.
- Without factory towing package: commonly around 2,000 pounds, with some variation by year and equipment.
- Aftermarket or non-standard setups: not recommended to exceed the factory rating; consult a Lexus dealer for guidance.
Because towing ratings can differ by year and trim, the precise figure for a given RX 300 should be confirmed on the data placard inside the driver’s door or in the owner’s manual for that year.
How to confirm your RX 300’s exact tow rating
To avoid misreading the numbers, check the official rating directly from the vehicle documentation and VIN-specific sources.
- Read the door jamb label to find the Gross Vehicle Weight Rating (GVWR) and the maximum trailer weight (MTW) or Towing Capacity.
- Consult the owner’s manual or Lexus service information for your exact model year and VIN to locate the official towing specification.
- When in doubt, contact a Lexus dealer or certified technician with your VIN to confirm the maximum tow rating and recommended towing equipment.
Knowing the official rating helps you plan loads safely and prevents damage to the drivetrain or suspension.
Best practices for towing with an RX 300
Beyond the official number, following best practices reduces risks while towing with this family crossover.
- Never exceed the published maximum trailer weight for your vehicle. Use a correctly rated hitch and wiring harness for the RX 300.
- Consider trailer brakes if required by law or if the trailer weight approaches the upper end of the rating.
- Aim for a tongue weight of roughly 10-15% of the trailer's gross weight for stable towing.
- Distribute load evenly in the trailer and ensure the towing setup is balanced to minimize sway and overheating.
Regular checks of cooling systems, transmission fluids, and brake performance are prudent when towing near the limit.
Bottom line
For most Lexus RX 300 models with the factory towing package, the maximum tow capacity is 3,500 pounds; without the package, it typically sits around 2,000 pounds, with some variation by year and drivetrain. Always verify the exact rating on the vehicle's data plate and in the owner’s manual before towing.
Summary: The RX 300 can tow a mid-size trailer when properly equipped, with up to 3,500 pounds available on models that include the factory towing package. Always confirm your model year’s specific rating and follow safe towing practices.
