qSafety 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.
qTrailer Lights
Trailer lights must comply with all federal, state, and local regulations. Equip your trailer
as required before towing it day or night.
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. Have
a recreational vehicle dealer or trailer rental agency connect the system, and inspect
the brake lights and turn signals yourself before each trip.
qTrailer Brakes
If the total trailer weight exceeds 450 kg (1,000 lb), trailer brakes are required. If your
trailer has brakes, make sure they comply with all federal, state, and local 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.
qTrailer Towing Tips
lVerify 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 tongue load, worn suspension parts, and trailer overloading.
lMake sure the trailer is properly loaded and the cargo is secure to prevent it from
shifting.
lMake sure the mirrors conform to all government regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.

WARNING
Remove the key only when the vehicle
is parked:
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur. (For vehicles
equipped with the advanced key, the
steering wheel locks when the starter
knob is turned to the LOCK position.)
Before leaving the driver's seat, always
put the key or start knob to LOCK
position, set the parking brake and
make sure the shift lever is in P:
It is important to place the key or
start knob in the LOCK position even
if you are not removing the key from
the ignition or leaving the vehicle.
Leaving the key in other positions
will disable some of the vehicle
security systems and run the battery
down.
Leaving the driver's seat without
putting the ignition switch in LOCK
position, setting the parking brake
and shifting the shift lever to P is
dangerous. Unexpected vehicle
movement could occur. This could
cause an accident.
NOTE
If turning the key is difficult, jiggle the steering
wheel from side to side.
Leaving the key or start knob in any position
but LOCK position also disables some of the
security features and may run the battery
down.
ACC (Accessory)
The steering wheel unlocks and some
electrical accessories will operate.
ON
This is the normal running position after
the engine is started. Some indicator
lights/warning lights should be inspected
before the engine is started (page 5-43).
NOTE
When the ignition switch is turned to the ON
position, the sound of the fuel pump motor
operating near the fuel tank can be heard. This
does not indicate an abnormality.
START
The engine is started in this position. It
will crank until you release the key. It
then returns to the ON position.
qIgnition Key Reminder
If the ignition switch is in the LOCK or
ACC position with the key inserted, a
continuous beep sound will be heard
when the driver's door is opened.
