Liftgate/Trunk Lid
WARNING
Never allow a person to ride in the
luggage compartment/trunk:Allowing a person to ride in the
luggage compartment/trunk is
dangerous. The person in the luggage
compartment/trunk could be seriously
injured or killed during sudden braking
or a collision.
Do not drive with the liftgate/trunk lid
open: Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/trunk lid
in a moving vehicle will cause exhaust
gas to be drawn into the cabin. This
gas contains CO (carbon monoxide),
which is colorless, odorless, and highly
poisonous, and it can cause loss of
consciousness and death. Moreover,
an open liftgate/trunk lid could cause
occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage compartment: Otherwise, the luggage may move
or collapse, resulting in injury or an
accident. In addition, do not load
luggage higher than the seatbacks. It
may affect the side or rear field of view.
CAUTION
 Before opening the liftgate/trunk lid,
remove any snow and ice accumulation
on it. Otherwise, the liftgate/trunk lid
could close under the weight of the snow
and ice resulting in injury.
 Be careful when opening/closing the
liftgate/trunk lid during strong winds.
If a strong gust blows against the
liftgate/trunk lid, it could close suddenly
resulting in injury.
 Fully open the liftgate/trunk lid and
make sure that it stays open. If the
liftgate/trunk lid is only opened partially,
it could slam shut by vibration or wind
gusts resulting in injury.
 When loading or unloading luggage in
the luggage compartment/trunk, turn
off the engine. Otherwise, you could get
burned by the heat of the exhaust gas.

Luggage Compartment
Luggage compartment cover (5-door)
WARNING
Do not place anything on top of the
cover:Placing luggage or other cargo on top
of the luggage compartment cover is
dangerous. During sudden braking or
a collision, the cargo could become
a projectile that could hit and injure
someone. The vehicle has a light
weight luggage compartment cover to
keep the contents of your luggage area
out of sight; it will not retain heavy
objects that are not tied down in an
accident such as a rollover. Tie down
all heavy objects, whether luggage or
cargo, using the tie down hooks.
Make sure luggage and cargo are
secured before driving: Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
CAUTION
Make sure the luggage compartment
cover is firmly secured. If it is not
firmly secured, it could unexpectedly
disengage resulting in injury. The luggage compartment can be accessed
by opening the liftgate when the straps are
attached to the sides of the liftgate.

Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap,
loosen the cap slightly and wait for any
hissing to stop, then remove it:Fuel spray is dangerous. Fuel can
burn skin and eyes and cause illness
if ingested. Fuel spray is released
when there is pressure in the fuel tank
and the fuel-filler cap is removed too
quickly.
Before refueling, stop the engine, and
always keep sparks and flames away
from the filler neck: Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
filler cap or not using a fuel-filler cap
may result in a fuel leak, which could
result in serious burns or death in an
accident.
Do not continue refueling after the fuel
pump nozzle shuts off automatically: Continuing to add fuel after the
fuel pump nozzle has shut off
automatically is dangerous because
overfilling the fuel tank may cause
fuel overflow or leakage. Fuel overflow
and leakage could damage the vehicle
and if the fuel ignites it could cause a
fire and explosion resulting in serious
injury or death.
CAUTION
Always use only a genuine Mazda fuel-
filler cap or an approved equivalent,
available at an Authorized Mazda
Dealer. The wrong cap can result in
a serious malfunction of the fuel and
emission control systems. It may also
cause the check engine light in the
instrument cluster to illuminate.
Fuel-Filler Lid
To open, pull the remote fuel-filler lid
release.
To close, press the fuel-filler lid until it
locks securely.

Driving Tips
Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:Downshifting into lower gear
while driving on slippery surfaces is
dangerous. The sudden change in tire
speed could cause the tires to skid. This
could lead to loss of vehicle control
and an accident.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
 Be cautious and allow extra distance for
braking. Avoid sudden braking and sudden
maneuvering. Do not pump the brakes. Continue to
press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 4-62. If you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
 For more traction in starting on slippery
surfaces such as ice or packed snow,
use sand, rock salt, chains, carpeting, or
other nonslip material under the front
wheels.
NOTE
Use snow chains only on the front wheels.
Floor Mat
WARNING
Make sure the floor mats are hooked on
the retention pins to prevent them from
bunching up under the foot pedals: Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
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.
If using a heavy duty floor mat for
winter use always remove the original
floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the floor
mat so that its grommets are inserted over
the pointed end of the retention posts.
