3–48
Before Driving
Driving Tips
Do not install two floor mats, one on top
of the other, on the driver's side:Installing two floor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
Loose floor mat(s) will interfere with
the foot pedals and could result in an
accident.
When using an all weather mat for
winter, always remove the original
floor mat.
When setting a floor mat, position the
floor mat so that its grommets or retainers
are inserted over the pointed end of the
retention posts.
Rocking the Vehicle
WARNING
Do not spin the wheels at more than
56 km/h (35 mph), 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 tire could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
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.

When Driving
Automatic Transaxle
Driving Tips
WARNING
Do not let the vehicle move in a
direction opposite to the direction
selected by the selector lever:Do not let the vehicle move backward
with the selector lever in a forward
position, or do not let the vehicle
move forward with the selector lever
in the reverse position. Otherwise, the
engine may stop, causing the loss of
the power brake and power steering
functions, and make it difficult to
control the vehicle which could result
in an accident.
Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transaxle will
shift to a lower gear, depending on vehicle
speed.
NOTE
 (Some models)
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how
much the accelerator pedal has been
depressed for performing kickdown,
and functions to control whether or not
kickdown should be performed.
 While the selector lever is in the M
position and the DSC is turned off,
manual shift mode does not switch
to automatic shift mode even if the
accelerator pedal is completely
depressed. Operate the selector lever.
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
To program the remaining two HomeLink
buttons, begin with “Programming”—
step 1
If the indicator light blinks rapidly
for two seconds and then turns
to a constant light, continue with
“Programming” steps 7—9 to
complete the programming of a rolling
code equipped device (most commonly
a garage door opener).
7. At the garage door opener receiver
(motor-head unit) in the garage, locate
the “learn” or “smart” button. This can
usually be found where the hanging
antenna wire is attached to the motor-
head unit.
8. Firmly press and release the “learn” or
“smart” button. (The name and color of
the button may vary by manufacturer.)
NOTE
Complete the programming within 30
seconds.
9. Return to the vehicle and firmly press,
hold for two seconds and release the
programmed HomeLink button. Repeat
the “ press/hold/release” sequence a
second time, and, depending on the
brand of the garage door opener (or
other rolling code equipped device),
repeat this sequence a third time to
complete the programming process.
HomeLink should now activate your
rolling code equipped device.
NOTE
To program the remaining two HomeLink
buttons, begin with “Programming”—
step 1
For questions or comments, please contact
HomeLink at www.homelink.com or 1-
800-355-3515.
Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
— which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian
law, some U.S. gate operators are designed
to “time-out” in the same manner.
If you live in Canada or you are having
difficulties programming a gate operator
by using the “Programming” procedures
(regardless of where you live), replace
“Programming HomeLink” step 3 with
the following:
NOTE
If programming a garage door opener or
gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
Continue to press and hold the HomeLink
button while you press and release
— every two seconds (“cycle”) your
hand-held transmitter until the frequency
signal has successfully been accepted by
HomeLink. (The indicator light will flash
slowly and then rapidly.)
Proceed with “Programming” step 4 to
complete.

If Trouble Arises
Overheating
Overheating
If the high engine coolant temperature
warning light turns on, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Pull over to a safe location, then
switch the ignition 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 indefinitely 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 hood 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 turns on:
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 hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood 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 Authorized Mazda
Dealer.
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.

If Trouble Arises
Overheating
If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
Cooling system cap
Coolant reservoir
Cooling fan
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
6-28).
CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda
Dealer.

If Trouble Arises
Warning/Indicator Lights and Warning Sounds
SignalWarning
(Red)High Engine Coolant
Temperature Warning Light
The light flashes when the engine coolant temperature is extremely high, and
illuminates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
Drive slowly to reduce engine load until you can find a safe place to stop the vehicle
and wait for the engine to cool down.
Illuminated light
This indicates the possibility of overheating. Park the vehicle in a saf\
e place
immediately and stop the engine.
Refer to Overheating
7-20.
CAUTION
Do not drive the vehicle with the high engine coolant temperature warning light illuminated. Otherwise, it could result in damage to the engine.
Power Steering Malfunction Indicator Light The light illuminates/flashes if the electric power steering has a malfunction.
If the light illuminates/flashes, stop the vehicle in a safe place and do not operate the
steering wheel. There is no problem if the light turns off after a while. Contact an
Authorized Mazda Dealer if the light illuminates/flashes continuously.
NOTEIf the indicator light illuminates/flashes, the power steering will not operate normally.
In this happens, the steering wheel can still be operated, however, the operation may
feel heavy compared to normal, or the steering wheel could vibrate when turning.
 Repeatedly jerking the steering wheel left and right while the vehicle i\
s stopped or
moving extremely slowly will cause the power steering system to go into protective
mode which will make the steering feel heavy, but this does not indicate a problem. If
this occurs, park the vehicle safely and wait several minutes for the sy\
stem to return
to normal.
