How much weight can a 2015 Lexus RX 350 tow?
The 2015 Lexus RX 350 can tow up to 3,500 pounds when it is equipped with the factory towing package and a proper hitch; without that equipment, towing capability is significantly limited and not recommended for heavy trailers.
Official capacity and required equipment
The official towing limit for the RX 350 applies to braked trailers up to 3,500 pounds, provided the vehicle carries Lexus’s towing package, which typically includes a Class III hitch and necessary cooling components for the engine and transmission. Models without the towing package are not rated for this level of towing and should not be asked to pull heavy trailers. Always verify the exact rating for your specific VIN in the owner's manual or with a Lexus dealer, as equipment and regional regulations can affect the limit.
These points outline the key factors that influence how much the RX 350 can tow and under what conditions the stated limit applies.
- Braked trailer capacity: up to 3,500 pounds with the factory towing package installed.
- Unbraked trailers: the official rating is not published for unbraked loads; towing without brakes is generally not recommended and may be restricted by law or by the vehicle’s documentation.
- Tongue weight: typically about 10–15% of the trailer’s gross weight (roughly 350–525 pounds for a fully loaded 3,500-pound trailer).
- Weight management: ensure the combined weight of the vehicle, passengers, cargo, and trailer does not exceed the RX 350’s GVWR or axle ratings as specified in the owner’s manual.
In practical terms, this means you can tow a mid-sized trailer, boat, or camper up to 3,500 pounds with the proper towing package, weight distribution, and braking system. Always confirm the exact configuration for your vehicle and comply with local regulations.
Practical towing considerations
To tow safely and within the vehicle’s limits, consider the equipment and practices that support stable handling and braking performance.
- Install and use the factory towing package, including a Class III hitch and recommended engine/transmission cooling components.
- Use a weight-distributing hitch and trailer brakes as appropriate for heavier loads and to improve stability.
- Load the trailer correctly, keeping tongue weight within the recommended range to maintain steering and braking control.
- Regularly inspect trailer lights, wiring, brakes, and tires; ensure compatibility with local requirements and safety standards.
- Drive with extra caution: allow for longer stopping distances, smoother acceleration, and gentler steering and cornering when towing.
Pre-tow preparation and safety checks
Before hitting the road, perform a quick checklist to minimize risk and wear on the vehicle and trailer.
- Check tire pressures on both vehicle and trailer and replace worn tires.
- Verify hitch connections, hitch ball size, and safety chains are secure.
- Ensure trailer brakes and electrical connections work properly and are legally compliant.
- Confirm coolant, oil, and transmission temperatures are within normal ranges during initial test drives with a load.
Summary
In summary, a 2015 Lexus RX 350 can tow up to 3,500 pounds when equipped with the official towing package and used with a braked trailer. The rating depends on proper equipment, weight distribution, and adherence to GVWR and axle limits. Always consult the owner's manual or a Lexus dealer for the exact specifications of your vehicle and follow safe towing practices for every trip.
