1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.
When towing a trailer, we recommend that you carry
a full-size spare wheel and tire for your vehicle and
trailer. If you use the compact spare tire that came
with your vehicle, it could adversely affect vehicle
handling.
2Specifications P. 421
2Changing a Flat Tire P. 391
Remember to unhitch the trailer before changing a
flat tire. Ask the trailer sales or rental agency where
and how to store the trailer’s spare tire.
