When returning the trip meter to “0”,
press the TRIP switch for 2 seconds or
longer while the trip meter is
displayed.
NOTE
If the lead-acid battery is disconnected
for vehicle maintenance or other
reasons, the trip meter display returns
to “0”.
High Voltage Battery Temperature Gauge

temperature. The blue range of the
gauge indicates that the high voltage
battery temperature is low and the red
range indicates that it is high and
overheating.

Engine Coolant
Temperature Gauge
Displays the engine coolant
temperature. The blue range of the
gauge indicates that the engine coolant
temperature is low, and the red range
of the gauge indicates that the engine
coolant temperature is high and
overheating.

CAUTION
If the engine coolant temperature
gauge needle is in the red range, there
is the possibility of overheating. Drive
slowly to reduce engine load.
Refer to Taking Action with
Overheating on page 8-20.
High Voltage Battery Powe r G au ge
The remaining power of the high
voltage battery is indicated when the
vehicle power is switched ON.
When the high voltage battery is fully
charged, F is indicated. As the level
lowers, the needle approaches E.

NOTE
After charging, it may require some
time for the needle to stabilize.
The arrow indicates that the
charging port is on the right side.

i-ACTIV AWD
AWD demonstrates superior driving
performance on slippery surfaces such
as snow-covered roads, sandy areas,
mud, and steep slopes.
Warnings and Cautionsfor Using the i-ACTIV AWD
WARNING
Do not rotate wheels that have left
the ground due to the vehicle being
stuck or in a ditch.
The drive component can be seriously
damaged, resulting in an accident. It
can also lead to overheating, oil
leakage, and fire.
CAUTION
This vehicle is not designed for
off-road and rally driving. Do not drive
over rough rocky roads and river beds.

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).

NOTE
Complete the programming within
30 seconds.
8. Return to the vehicle and firmly press and hold the Homelink
button, and then release it after two
seconds have passed. 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.
Press the programmed HomeLink
button and make sure that the
HomeLink System operates.
If the status indicator arrows are
flashing , refer to Programming

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 are having
difficulties programming a gate
operator by using the programming
procedures (regardless of where you
live), replace Step 4 of Programming
the HomeLink System 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.
While the indicator light is flashing in
amber, press the button on the
hand-held transmitter for 2 seconds
and release it repeatedly until the
indicator light changes from amber to
green.
Go back to Step 5 of Programming the
HomeLink System to complete the
procedure.
Operating the HomeLink System
Press the programmed HomeLink
button to operate a programmed
device.
Reprogramming the HomeLink system
To program a device to HomeLink
using a HomeLink button previously
trained, follow these steps:
1. Press and hold the desired
HomeLink button. Do not release
the button.
2. After 20 seconds, the indicator light
flashes in amber. After the indicator
light flashes, release the HomeLink
button.

Ta k i n g A c t i o n w i t hOverheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning light is displayed, 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 vehicle power 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.

1. Drive safely to the side of the road and park off the right-of-way.
2. Shift into park (P).
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.
