Before Driving
Towing
▼ Tyres
When towing a trailer, make sure all
tyres are inflated to the recommended
cold-tyre pressure, as indicated on the
tyre pressure chart on the driver's door
frame. Trailer tyre size, load rating, and
inflation pressures should conform to
tyre manufacturer specifications.
WARNING
Never use the temporary spare tyre
when towing:
Using the temporary spare tyre on your
vehicle when towing a trailer is
dangerous as it could result in tyre
failure, loss of control, and injury to
vehicle occupants.
▼ Safety Chains
Safety chains must be used as a
precautionary measure should the
trailer become unintentionally
unhitched. They should cross under the
trailer tongue and attach to the hitch.
Leave enough slack to allow full turns.
Consult literature published by your
trailer or hitch manufacturer for more
details.
WARNING
Make sure the safety chain is securely
attached to both the trailer and the
vehicle prior to departure:
Towing a trailer without using a safety
chain securely attached to both the
trailer and the vehicle is dangerous. If
damage occurs to the coupling unit or
hitch ball, the trailer could wander into
another lane and cause a collision.

▼ Trailer Lights
CAUTION
Do not connect a trailer lighting system
directly to the lighting system of your
Mazda. This may damage your
vehicle's electrical system and lighting
systems. To connect the lighting
system, consult an expert repairer (we
recommend an Authorised Mazda
Repairer)
▼ Trailer Brakes
Check the Maximum trailer
towing-load table in Weight Limits
(page 3-61), 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

or unloaded trailer is connected. Do
not drive if it has an abnormal
front-up or front-down position.
