Trailer Towing Tips
Before driving
 




 Verify that your Mazda maintains a near-normal attitude when a loaded or unloaded trailer
is connected. Do not drive if it has an abnormal front-up or front-down position. Inspect
for incorrect nose weight, worn suspension parts, and trailer overloading. Have the vehicle
inspected by an expert repairer, we recommend an Authorised Mazda Repairer.
 


 Make sure the trailer cargo is secure to prevent it from shifting.



 Make sure the mirrors meet all government regulations. Inspect them.



 Before starting out, inspect the operation of all vehicle and trailer lights and all vehicle-
to-trailer connections. Stop and re-inspect all lights and connections after driving a short
distance.
Driving
 




 Your Mazda will handle differently with a trailer in tow, so practice turning, backing, and
stopping in a traffi c-free area.




 Take time to get accustomed to the extra weight and length.



 Do not exceed 100 km/h (62 mph) with a trailer in tow. If the local legal maximum speed
with a trailer in tow is less than 100 km/h (62 mph), do not exceed the legal speed.
CAUTION
If the vehicle exceeds 100 km/h (62 mph) with a trailer in tow, the vehicle could be
damaged.
 


 When ascending a hill, shift into a lower gear to reduce the possibility of overloading or
overheating the engine, or both.
 


 When descending a hill, shift into a lower gear and use engine compression as a braking
effect. Pay constant attention to speed and use the brakes only as needed. Holding the
brake pedal down for a prolonged period may cause the brakes to overheat and lose
power.
