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.

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.

Trailer tire size, load rating, and inflation pressures should conform to tire
manufacturer specifications.
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.
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.
Tra i l e r l i g h t s
Trailer lights must comply with all federal, state, and local regulations. Equip your
trailer as required before towing it day or night.
Trailer 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.
Driving
Your Mazda will handle differently with a trailer in tow, so practice turning ,
backing , and stopping in a traffic-free area.
Take time to get accustomed to the extra weight and length.Allow more room between your vehicle and the one in front because braking
distance increases with a trailer. For each 16 km/h (10 mph) of speed, allow at
least one vehicle and trailer length between your Mazda and the vehicle ahead.
Avoid jerky starts or sudden acceleration.Avoid sudden braking. It may cause loss of control and result in
jackknifing,
especially so on wet or slippery roads.
Shift the selector lever to the D position when towing a trailer in hilly terrain or
when heavily loaded.
The D position will allow operating the vehicle without frequent shifting.
Lane changes and turning
Avoid quick lane changes, sudden turns, and tight turns. Slow down before turning
to avoid the need of sudden braking.
A turning trailer will make a tighter arc than the tow vehicle. Compensate with turns
that are larger than normal.
Pa s s i n g
Plan well ahead to pass other vehicles, and provide plenty of room before changing
lanes. Crosswinds from passing vehicles, especially larger ones, and the effects of
rough roads will affect handling.

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).
