Before Driving
Driving Tips
Rocking the Vehicle
WARNING
Do not spin the wheels at high speed,
and do not allow anyone to stand
behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning
the wheels at high speed is dangerous.
The spinning tyre could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tyre
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the shift lever
from 1 (D) to R.
Winter Driving
Carry emergency gear, including tyre
chains, window scraper, fl ares, a small
shovel, jumper leads, and a small bag of
sand or salt.
Ask an expert repairer, we recommend an
Authorised Mazda Repairer to check the
following:
 


 Have the proper ratio of antifreeze in the
radiator.
  Refer to Engine Coolant on page 6-30 .



 Inspect the battery and its leads. Cold
reduces battery capacity.
 


 Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-23 ).
 


 Inspect the ignition system for damage
and loose connections.
 


 Use washer fl uid made with antifreeze—
but do not use engine coolant antifreeze
for washer fl uid (page 6-34 ).
NOTE

 Do not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transaxle and to 1 or R with a manual
transaxle. Block the rear wheels.
  Remove snow before driving. Snow
left on the windscreen is dangerous
as it could obstruct vision.
  Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windscreen.

Towing
Trailer Towing Tips
Before driving
 




 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 incorrect nose weight, worn suspension parts, and trailer overloading. Have the vehicle
inspected by an expert repairer, we recommend an Authorised Mazda Repairer.
 


 Make sure the trailer cargo is secure to prevent it from shifting.



 Make sure the mirrors meet all government regulations. Inspect them.



 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.
Driving
 




 Your Mazda will handle differently with a trailer in tow, so practice turning, backing, and
stopping in a traffi c-free area.




 Take time to get accustomed to the extra weight and length.



 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.
CAUTION
If the vehicle exceeds 100 km/h (62 mph) with a trailer in tow, the vehicle could be
damaged.
 


 When ascending a hill, shift into a lower gear to reduce the possibility of overloading or
overheating the engine, or both.
 


 When descending a hill, shift into a lower gear and use engine compression as a braking
effect. Pay constant attention to speed and use the brakes only as needed. Holding the
brake pedal down for a prolonged period may cause the brakes to overheat and lose
power.

When Driving
Transaxle
Climbing steep grades from a stop
To climb a steep grade from a stopped
position:
1. Depress the brake pedal.
2. Shift to D or M1, depending on the
load weight and grade steepness.
3. Release the brake pedal while gradually
accelerating.
Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.

When Driving
Switches and Controls
NOTE
Because heavy ice and snow can jam
the wiper blades, the wiper motor is
protected from motor breakdown,
overheating and possible fi re by a
circuit breaker. This mechanism will
automatically stop operation of the
blades, but only for about 5 minutes.
If this happens, turn off the wiper switch
and park off the right-of-way, and
remove the snow and ice.
After 5 minutes, turn on the switch and
the blades should operate normally. If
they do not resume functioning, consult
an expert repairer, we recommend an
Authorised Mazda Repairer as soon as
possible. Drive to the side of the road
and park off the right-of-way. Wait until
the weather clears before trying to drive
with the wipers inoperative.

Interior Features
Air-Conditioning System
CAUTION
If the air conditioner is used while
driving up long hills or in heavy traffi c,
monitor the engine coolant temperature
warning light to see if it is illuminated or
fl ashing (page 4-40 ).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or fl ashing, turn the air
conditioning off (page 7-26 ).
NOTE

(Type A) When maximum cooling is desired,
set the temperature control dial to
the extreme cold position and set the
air intake selector to the recirculated
air position, then turn the fan control
dial fully clockwise.
 (Type B) When maximum cooling is desired,
set the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then set the fan control dial
to position 4.
  If warmer air is desired at fl oor level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.
  The air to the fl oor is warmer than
air to the face (except when the
temperature control dial is set at the
extreme hot or cold position).
Ventilation
1. Set the mode selector dial to the
position.
2. Set the air intake selector to the outside
air position.
3. Set the temperature control dial to the
desired position.
4. Set the fan control dial to the desired
speed.
Windscreen Defrosting and
Defogging
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the
desired position.
3. Set the fan control dial to the desired
speed.
4. If dehumidifi ed heating is desired, turn
on the air conditioner.
WARNING
Do not defog the windscreen using the
position with the temperature
control set to the cold position:
Using the
position with the
temperature control set to the cold
position is dangerous as it will cause
the outside of the windscreen to fog up.
Your vision will be hampered, which
could lead to a serious accident. Set the
temperature control to the hot or warm
position when using the
position.

If Trouble Arises
Flat Tyre
WARNING
Never use the air compressor above 300
kPa (3.1 kgf/cm 2 , 3 bar, 43.5 psi):
Using the air compressor at an
infl ation pressure above 300 kPa (3.1
kgf/cm
2 , 3 bar, 43.5 psi) continuously
is dangerous. If the air compressor
overheats, hot air will be exhausted and
you could get burned.
CAUTION
If the air compressor operates slowly or
becomes hot, this indicates overheating.
Turn the air compressor OFF
immediately and cancel the procedure.
In this case, leave the air compressor
turned OFF for about 30 minutes or
longer and wait until the temperature
decreases.
NOTE
  Check the tyre infl ation pressure
label (driver's door frame) for the
correct tyre infl ation pressure.

 Do not operate the air compressor for
a continuous 10 minutes or longer
because using it for long periods
could cause a malfunction.
  If the tyre infl ation pressure does
not increase, repair of the tyre is not
possible. If the tyre does not reach
the specifi ed tyre infl ation pressure
within 10 minutes, it may have
received extensive damage. In this
case, the repair using the emergency
fl at tyre repair kit was not successful.
Contact an expert repairer, we
recommend an Authorised Mazda
Repairer.
13. Adhere the speed restriction sticker to
an area where it can be viewed easily
by the driver.

If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Switch the ignition to off and
make sure the fan is not running
before attempting to work near the
cooling fan:
Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefi nitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either
cooling system cap when the engine
and radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
Open the bonnet ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the bonnet and start the engine.
If neither coolant nor steam is
escaping:
Open the bonnet and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an expert repairer,
we recommend an Authorised Mazda
Repairer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.
