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
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 TCS 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.

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-31.
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 than 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.
NOTE
Check the tire inflation pressure label
attached to driver's door frame for the
correct tire inflation pressure.

Overheating
If the temperature gauge indicates
overheating or 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 temperature gauge indicates
overheating or 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. 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.

6-22).
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
