Snow Tires
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all 4
wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident.
CAUTION
Check local regulations before using
studded tires.
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75
mph) while driving with snow tires.
When installing winter tires, use tires of
the specified size and adjust the air
pressure of all the tires to the specified
value. (page 10-71).
The vehicle is originally equipped with
all season radials designed to be used
all year around. In some extreme
climates you may find it necessary to
replace them with snow tires during
the winter months to further improve
traction on snow and ice covered
roads.
Tire Chains
Check local regulations before using
tire chains.
CAUTION
Chains may aff ect handling.
Do not go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
Drive carefully and avoid bumps,
holes, and sharp turns.
Avoid locked-wheel braking.
Do not use chains on a temporary
spare tire; it may result in damage to
the vehicle and to the tire.
Do not use chains on roads that are
free of snow or ice. The tires and
chains could be damaged.
Chains may scratch or chip
aluminum wheels.
NOTE
The tire pressure monitoring system
may not function correctly when using
tire chains.
Install the chains on the rear tires only.
Do not use chains on the front tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Secure the chains on the rear tires
as tightly as possible. Always follow
the chain manufacturer's
instructions.
2. Retighten the chains after driving 1/2 ―1 km (1/4 ―1/2 mile).

TTW and GCWR
The total trailer weight (TTW), gross combination weight rating (GCWR), gross axle
weight rating (GAWR), trailer load, and trailer tongue load must be within the
prescribed limits.
The total trailer weight (TTW) is the sum of the weights of the trailer load (trailer
weight plus cargo). Never allow the total trailer weight (TTW) to exceed specifications in the Trailer towing-load table.
The maximum GCWR is the combination weight of the trailer and load plus the
towing vehicle (including trailer hitch, vehicle passengers, and load). It must not
exceed the specifications in the load table.
GAWR and GVWR
Do not exceed front and rear GAWR (gross axle weight rating) and GVWR (gross
vehicle weight rating). If you do, vehicle handling , braking , and performance will be
affected. These values are also on the Motor Vehicle Safety Standard Label posted
on the driver's door frame.
Trailer frontal area table
Frontal area is the total area that a moving vehicle and trailer exposes to air
resistance. Exceeding this limit may reduce the performance of your towing vehicle.
(U.S.A. and Canada)

Before driving
Have your cooling and braking system checked by an Authorized Mazda Dealer.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.
Trailer hitch
Use only a hitch ball recommended by the trailer manufacturer that conforms to the
gross trailer weight requirement.
When not towing a trailer, remove the trailer hitch (if detachable) to reduce the
possibility of damage as a result of the vehicle being rear-ended.
Tires
When towing a trailer, make sure that the tire pressures of the rear tires are at 20
kPa (0.2 bar, 2.9 psi) higher than the recommended tire pressures indicated on
the tire pressure chart on the driver's door frame.

If swaying occurs, firmly grip the steering wheel and reduce speed immediately, but
gradually.
Steer straight ahead. If no extreme correction of steering or braking is made, the
combination of less speed and firm steering will result in stability.
Backing up
Backing a vehicle with a trailer requires practice and patience. Back slowly, and have
a helper outside at the rear of the trailer to reduce the risk of an accident.
To turn the trailer, place your hand at th e bottom of the steering wheel and turn it in
the direction you want the trailer to go. Make only slight movements to prevent
sharp or prolonged turning.
Ascending a hill
Shift into a lower gear to reduce the poss ibility of overloading or overheating the
engine, or both.
Descending a hill
Shift into a lower gear and use engine compression as a braking effect.
Pa r k i n g
Always make sure the tires of the trailer and the tow vehicle are blocked while
parked.
Apply the parking brake firmly and put the transmission in P.
Avoid parking on an incline, but if you must, follow these instructions:
1. Depress and hold down the brake pedal.
2. Have a helper put wheel blocks against the downhill side of all vehicle and trailer tires.
3. Then release the brake pedal slowly until the blocks bear the load.
If the grade is downhill, turn the steering wheel so that the front of the front
tires face the curb.
If it is uphill, face the rear of the front tires against the curb.
4. Firmly apply the parking brake.
5. Shift the transmission into P, and stop the engine.
To restart after parking on an incline:
1. With the transmission in P, start the engine. (Be sure to depress and hold the brake pedal.)
2. Shift into gear.
3. Release the parking brake (also the foot brake) and pull away from the wheel blocks. Stop; apply the parking brake and shift into P.
4. Have a helper retrieve the wheel blocks.
Maintenance
If you tow a trailer frequently, have your vehicle serviced as shown in Scheduled
Maintenance (page 9-4).

Spare Tire
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the rear wheels (driving wheels).
Driving with the temporary spare tire
on one of the rear driving wheels is
dangerous. Handling will be affected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the rear wheel and install the
temporary spare tire to the front.
CAUTION
When using the temporary spare tire,
driving stability may decrease
compared to when using only the
conventional tire. Drive carefully.
To avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
Do not exceed 80 km/h (50 mph).
Avoid driving over obstacles. Also,
do not drive through an automatic
car wash. This tire's diameter is
smaller than a conventional tire, so
the ground clearance is reduced.
Do not use a tire chain on this tire
because it will not fit properly.
Do not use your temporary spare
tire on any other vehicle, it has
been designed only for your
Mazda.
Use only one temporary spare tire
on your vehicle at the same time.
To remove the spare tire
1. Remove the luggage board.
2. Remove the cargo sub compartment.
3. (Vehicles with sub-woofer)
Uncouple the sub-woofer
connector.
