Before Driving
Towing
Trailer Brakes
Check the Maximum trailer towing-load table in Weight Limits (page 3-54 ), and if your
trailer weight exceeds the value in the TOTAL TRAILER WEIGHT (Trailer without brake),
trailer brakes are required.
If your trailer has brakes, make sure they meet regulations.
WARNING
Do not connect a hydraulic trailer-brake system to your vehicle's brake system:
Connecting a hydraulic trailer-brake system directly to the vehicle brake system is
dangerous and will result in inadequate braking and possible injury.
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.

Before Driving
Towing
 


 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.
Parking
Avoid parking on an incline with a trailer. If this must be done, follow these instructions.
Parking on an Incline
1. Set the parking brake and the brakes.
2. Have someone block the wheels of the vehicle and trailer while you apply the brakes.
3. After the wheels are blocked, release the parking brake and the brakes slowly, allowing
the blocks to bear the load.
4. Set the parking brake fi rmly.
5. If the vehicle has an automatic transaxle, put the selector lever in P. If it has a manual
transaxle, place the gear shift in 1 or R.
Starting on an Incline
1. Start the engine (page 4-5 ).
2. Release the parking brake and slowly pull away a short distance from the wheel blocks.
3. Stop on the nearest level ground, set the parking brake, and pick up the wheel blocks.

  Under the following conditions,
the radar sensor (front) may not
be able to detect vehicles ahead
or obstructions correctly and each
system may not operate normally.
 


 The rear surface of a vehicle
ahead does not refl ect radio waves
effectively, such as an unloaded
trailer or an automobile with a
loading platform covered by a
soft top, vehicles with a hard
plastic tailgate, and round-shaped
vehicles.
 


 Vehicles ahead with low vehicle
height and thus less area for
refl ecting radio waves.




 Visibility is reduced due to a
vehicle ahead casting off water,
snow, or sand from its tyres and
onto your windscreen.
 


 The luggage compartment is
loaded with heavy objects or the
rear passenger seats are occupied.
 


 Ice, snow, or soiling is on the front
surface of the front emblem.
 


 During inclement weather such as
rain, snow, or sand storms.
