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.
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.
CAUTION
Do not tow a trailer during the first
1,000 km (600 miles) of your new
Mazda. If you do, you may damage
the engine, transmission, differential,
wheel bearings, and other
power-train components.
 Be aware of the towing load weight
differences when towing at high
altitudes. For altitudes exceeding
1,000 meter (3,280 ft 10 in), always
reduce the towing load by 10 % for
every 1,000 meter (3,280 ft 10 in)
increase in altitude from the load
indicated under the maximum
GCWR heading in the trailer
towing-load table. If the determined
maximum total towing load weight is
exceeded, the engine and other
power-train parts may be damaged.
 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.
Make all hitch adjustments with
actual loads. Do not load and
unload vehicle while adjusting hitch.
This action will change the vehicle
height.
 Do not use an axle-mounted hitch.
This may damage the axle and
related parts.
 If the vehicle exceeds 100 km/h (62
mph) with a trailer in tow, the
vehicle could be damaged.
 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.

How to Use the Towing
NOTE
The three main causes of vehicle-trailer accidents are driver error, excessive speed,
and improper trailer loading.
Trailer towing causes higher fuel consumption.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.
Verify 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 incorrec t 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 govern ment regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.

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).

Taking Action with Depleted Lead-acid Battery
The lead-acid battery might be depleted if the following conditions occur.
The hybrid system does not start.The selector lever cannot be shifted to a position other than P.The horn sound is weak or it does not sound.The brightness of the lights is extremely low.
Using commercially available booster cables, connect the lead-acid battery of the
booster vehicle’s battery to the lead-acid battery of your vehicle and start the hybrid
system.
Jump-starting is dangerous if done incorr ectly. Therefore, follow the procedure
carefully. If you feel unsure about jump-s tarting , we strongly recommend that you
have a competent service technician do the work.
WARNING
Read the following precautions carefully before using the lead-acid
battery or inspecting to ensure safe and correct handling.
Always wear eye protection when working near the lead-acid battery.
Working without eye protection is dangerous. Lead-acid battery fluid contains
SULFURIC ACID which could cause blindne ss if splashed into your eyes. Also,
hydrogen gas produced during normal lead-acid battery operation, could ignite and
cause the lead-acid battery to explode.
Wear eye protection and protective gloves to prevent contact with
lead-acid battery fluid.
Spilled lead-acid battery fluid is dangerous.
Lead-acid battery fluid contains SULFURIC ACID which could cause serious injuries if
it gets in eyes, or on the skin or clothing. If this happens, immediately flush your eyes
with water for 15 minutes or wash your skin thoroughly and get medical attention.
Always keep lead-acid batteries out of the reach of children.
Allowing children to play near lead-acid batteries is dangerous. Lead-acid battery
fluid could cause serious injuries if it gets in the eyes or on the skin.

allow metal tools to contact the positive (+) or negative (-) terminal of the
lead-acid battery when working near a lead-acid battery. Do not allow the
positive (+) terminal to contact the vehicle body.
Flames and sparks near lead-acid battery cells are dangerous. Hydrogen gas,
produced during normal lead-acid battery operation, could ignite and cause the
lead-acid battery to explode. An exploding lead-acid battery can cause serious burns
and injuries. Keep all flames including cigarettes and sparks away from lead-acid
battery cells.
Keep all flames and sparks away from lead-acid battery cells
because hydrogen gas is produced from le ad-acid battery cells while charging the
lead-acid battery or adding lead-acid battery fluid.
Flames and sparks near lead-acid battery cells are dangerous. Hydrogen gas,
produced during normal lead-acid battery operation, could ignite and cause the
lead-acid battery to explode. An exploding lead-acid battery can cause serious burns
and injuries. Keep all flames including cigarettes and sparks away from lead-acid
battery cells.
Do not jump-start a frozen lead-acid battery or one with a low fluid level.
Jump-starting a frozen lead-acid battery or one with a low fluid level is dangerous. It
may rupture or explode, causing serious injury.
Connect the negative cable to a good ground point away from the lead-acid
battery.
Connecting the end of the second jumper cable to the negative (–) terminal of the
depleted lead-acid battery is dangerous.
A spark could cause the gas around the lead-acid battery to explode and injure
someone.
Route the jumper cables away from parts that will be moving.
Connecting a jumper cable near or to moving part (cooling fans) is dangerous. The
cable could get caught when the hybrid system starts and cause serious injury.
