Odometer
The odometer records the total
distance the vehicle has been driven.
Tr i p m e te r
The driving distance for a specified
interval is indicated. Two types (TRIP A,
TRIP B) of interval distance can be
measured.

For instance, trip meter A can record
the distance from the point of origin,
and trip meter B can record the
distance from where the fuel tank is
filled.

When trip meter A is selected, TRIP A
will be displayed. When trip meter B is
selected, TRIP B will be displayed.

The trip meter can be reset by pressing
the TRIP switch for 1.5 seconds or
more while the trip meter is displayed.
NOTE
Only the trip meters record tenths of
kilometers (miles).
▼ Engine Coolant Temperature

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the
engine coolant temperature is
extremely high. Drive slowly to reduce
engine load. If the engine coolant
temperature gauge needle is in the red
range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take
appropriate measures.
Refer to Overheating on page 7-17.
NOTE
If the engine or engine coolant
temperature is high or low, the
engine output may be restricted to
protect the engine.
▼Fuel Gauge
The fuel gauge shows approximately
how much fuel is remaining in the tank
when the ignition is switched ON. We
recommend keeping the tank over 1/4
full.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warning light illuminates
or the fuel level is very low, refuel as
soon as possible.
If inconsistency in engine performance
or stalling occurs due to low fuel level
conditions, refuel the vehicle as soon
as possible and add at least 10 L (2.7
US gal, 2.2 Imp gal) of fuel.

Driving Tips
▼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.
Pa s s i n g
For extra power when passing another
vehicle or climbing steep grades,
depress the accelerator fully. The
transmission will shift to a lower gear,
depending on vehicle speed.
NOTE
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.
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.

▼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 3 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 4 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.
3. Go back to Step 2 of Programming the HomeLink System to complete
the procedure.
NOTE
If the programming has not been
completed, the system returns to the
previous programming.

i-ACTIV AWD Operation*
▼i-ACTIV AWD Operation
AWD provides excellent drivability on
snow-covered and ice-packed roads,
sand and mud, as well as on steep
slopes and other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to AWD Warning Indication/
Warning Light on page 7-27.
WARNING
Never spin a wheel that is off the
ground:
Spinning a wheel that
is off the ground
as a result of the vehicle being stuck or
in a ditch is dangerous. The drive
assembly could be seriously damaged
which could lead to an accident or
could even lead to overheating, oil
leakage, and a fire.
▼AWD Driving
WARNING
Avoid sharp turns, excessive speed
and abrupt maneuvers when driving
this vehicle:
Sharp turns, excessive speed and
abrupt maneuvering of this vehicle is
dangerous as it could result in the
increased risk of loss of vehicle control,
vehicle roll-over, personal injury or
death.
This vehicle has a higher center of
gravity. Vehicles with a higher center of
gravity such as utility and AWD vehicles
handle differently th
an vehicles with a
lower center of gravity.
Utility and AWD vehicles are not
designed for cornering at high speeds
any more than low profile sports cars
are designed to perform satisfactorily
under off-road conditions. In addition,
utility vehicles have a significantly
higher rollover rate than other types of
vehicles.
Drive carefully when the vehicle is
loaded by lowering vehicle speed and
applying the brakes earlier:
Abrupt maneuvering and sudden
braking when driving a loaded vehicle
is dangerous as the driving behavior of
a vehicle with a high center of gravity is
different when it is loaded compared
to when it is not, and could result in
the loss of vehicle control and an
accident.
▼ Tires and Tire Chains
The condition of the tires plays a large
role in the performance of the vehicle.
Moreover, to prevent adverse
effects to
the drive assembly, please note the
following:
Tires
When replacing tires, always replace
all front and rear tires at the same
time.
All tires must be of the same size,
manufacture, brand and tread
pattern. Pay particular attention
when equipping snow or other types
of winter tires.
Do not mix tread-worn tires with
normal tires.
Inspect tire inflation pressures at the specified periods adjust to the
specified pressures.

Overheating
▼Overheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication 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 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 engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed:

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.
