Trailer Towing
Your Mazda was designed and built primarily to carry passengers and cargo.
If you tow a trailer, follow these instructions because driver and passenger
safety depends
on proper equipment and safe driving habits. Towing a trailer will affect
handling, braking,
durability, performance, and economy.
Never overload vehicle or trailer. Consult an Authorized Mazda Dealer if you
need further
details.
CAUTION:
Don't tow a trailer during the first 1,000 km (600 miles) of your new Mazda. If
you
do, you may damage the engine, transaxle, differential, wheel bearings, and
other
power train components.
Weight Limits
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), trailer hitch, vehicle passengers, and vehicle load. 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 specifications in the load table.
GAWR and GVWR
Don't 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 Certification Label posted on
the driver's
door frame.
High-altitude operation
In a high-altitude operating environment, a gasoline engine loses power at a
rate of 3% to
4% per 304 m (1,000 ft) of elevation. In these conditions, a reduction in gross
vehicle
weight and gross combination weight is recommended.
TRAILER TOWING-LOAD TABLE
Because vehicle weights vary, adjustments must be made to meet the
requirements in this
table.
GCWR: Gross Combination Weight Rating (sum of TTW, vehicle weights and 2 passengers).
GAWR: Gross Axle Weight Rating.
GVWR: Gross Vehicle Weight Rating.
WARNING:
Always keep tow loads within specified limits as indicated in the Trailer
Towing-Load
Table:
Attempting to tow loads greater than those specified is dangerous as it may
cause
serious handling and performance problems that could result in personal injury
or
vehicle damage, or both.
Load your trailer with the weight about 60% toward the front and 40% toward the
rear:
Loading the trailer with more weight in the rear than in the front is dangerous.
Doing so could cause you to lose control. The trailer tongue load must be
10%―15%
of the total trailer load (sum of the weights of the trailer and cargo).
Always have the total trailer weight and tongue load determined prior to
departure:
Attempting to tow loads without determining the total trailer weight and tongue
load is dangerous. Trailer sway from crosswinds, rough roads or other causes
could
result in loss of control and a serious accident.
CAUTION:
The total trailer weight and tongue load can be determined by weighing the
trailer
on platform scales at a highway weight station or a trucking company.
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.
WARNING:
Always make sure the trailer hitch is securely attached before departure:
An unsecured trailer hitch is dangerous as it causes greater trailer sway from
crosswinds, rough roads or other causes, resulting in loss of control and a
serious
accident.
Examine all trailer-hitch mounting bolts regularly and tighten any that are
loose. If
the hitch is removed, seal any open mounting holes to prevent exhaust, dust,
water,
dirt and other foreign elements from filtering in, possibly endangering personal
safety and damaging your vehicle.
Do not install a hitch that stiffens the bumper as it will reduce the bumper's performance.
Make sure there are no exhaust gas leaks into the passenger compartment if any mounting bolts are connected to the body: Modifying your vehicle exhaust system is dangerous. Exhaust gas entering the vehicle could cause loss of consciousness or even death.
When mounting the trailer hitch, make no modifications to the vehicle exhaust system.
CAUTION:
Make all hitch adjustments with actual loads. Don't load and unload vehicle
while
adjusting hitch. This action will change the vehicle height.
Don't use an axle-mounted hitch. This may damage the axle and related parts.
Tires
When towing a trailer, make sure all tires are inflated to the recommended
cold-tire
pressure, as 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.
WARNING:
Never use the temporary spare tire when towing:
Using the temporary spare tire on your vehicle when towing a trailer is
dangerous as
it could result in tire 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
Trailer lights must comply with all federal, state, and local regulations.
Equip your trailer
as required before towing it day or night.
CAUTION:
Don't 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.
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.
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
- Verify that your Mazda maintains a near-normal attitude when a loaded or
unloaded
trailer is connected. Don't drive if it has an abnormal front-up or front-down
position.
Inspect for incorrect tongue load, worn suspension parts, and trailer overloading.
- Make sure the trailer is properly loaded and the cargo is secure to prevent it
from
shifting.
- Make sure the mirrors conform to all government regulations. If they do not,
install
required rear view mirrors appropriate for towing purposes.
The three main causes of vehicle-trailer accidents are driver error,
excessive speed, and
improper trailer loading.
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 vehicleto-
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 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 shift lever to the D position when towing a trailer in hilly terrain
or when
heavily loaded.
These positions 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.
Passing
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 the 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 possibility of overloading or overheating the engine, or both.
Descending a hill
Shift into a lower gear and use engine compression as a braking effect.
WARNING:
Always use lower gears to reduce speed:
Holding the brake pedal down too long or too frequently is dangerous as it could
cause the brakes to overheat and lose power, resulting in loss of control and a
serious accident. Use lower gears to help reduce speed. Pull off the road and
allow
brakes to cool down whenever braking performance feels reduced.
Overheated engine
The extra weight of the trailer may strain the engine on hot days and on long
or steep
upgrades.
If the temperature gauge indicates overheating, turn off the air conditioner,
drive safely to
the side of the road, park off the right-of-way and wait for engine to cool.
Refer to
Overheating.
Parking
Always make sure the tires of the trailer and the tow vehicle are blocked while parked.
Apply the parking brake firmly and put the transaxle 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 transaxle into P, and stop the engine.
To restart after parking on an incline:
1. With the transaxle 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.
Fuel consumption
Trailer towing causes higher fuel consumption.
Maintenance
If you tow a trailer frequently, have your vehicle serviced as shown in
Scheduled
Maintenance.
