▼Engine Exhaust (Carbon monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas contai
ns carbon monoxide (CO), which is colorless,
odorless, and poisonous. When inhaled, it can cause loss of consciousness and death. If you
smell exhaust gas inside the vehicle, keep al l windows fully open and contact an Authorized
Mazda Dealer immediately.
Do not run the engine when inside an enclosed area:
Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust gas,
which contains poisonous carbon monoxide , could easily enter the cabin. Loss of
consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when idling the
engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and the
engine running for a long time even in an open area, exhaust gas, which contains poisonous
carbon monoxide, could enter the cabin. Loss of consciousness or even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe, before
starting the engine:
Running the engine when a vehicle is stopped in deep snow is dangerous. The exhaust pipe
could be blocked by the snow, allowing exhaus t gas to enter the cabin. Because exhaust gas
contains poisonous carbon monoxide, it could cause loss of consciousness or even death to
occupants in the cabin.

Fuel-Filler Lid and Cap
WA R N I N G
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.
(U.S.A. and Canada)
It may also cause the check engine light in
the instrument cluster to illuminate.
▼ Refueling
Before refueling, close all the doors,
windows, and the liftg
ate, and switch the
ignition OFF.
1. To open the fuel-filler lid, pull the remote fuel-filler lid release.

5. To close the fuel-filler cap, turn it clockwise until a click is heard.
6. To close, press the fuel-filler lid until it locks securely.

CAUTION
(U.S.A. and Canada)
If the check fuel cap warning light
illuminates, the fuel-filler cap may not be
properly installed. If the warning light
illuminates, park your vehicle safely off the
right-of-way, remove th e fuel-filler cap and
reinstall it correctly. After the cap has been
correctly installed, the fuel cap warning
light may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of starting
the engine (after four or more hours with
the engine off) and driving the vehicle on
city and highway roads.
Continuing to drive with the check fuel cap
warning light illuminated could cause the
check engine light to illuminate as well.

Power Windows
The windows can be opened/closed by operating the power window switches.
WA R N I N G
Make sure the opening is clear before closing a window:
Closing a power window is dangerous. A person's hands, head, or even neck could be caught
by the window and result in serious injury or even death. This warning applies especially to
children.
Never allow children to play with power window switches:
Power window switches that are not locked wi th the power window lock switch would allow
children to operate power windows unintentionally, which could result in serious injury if a
child's hands, head or neck becomes caught by the window.
Make sure nothing blocks the window just before it reaches the fully closed position or while
holding up the power window switch:
Blocking the power window just before it reache s the fully closed position or while holding up
the power window switch is dangerous.
In this case, the jam-safe function cannot prevent the window from closing all the way. If
fingers are caught, seriou s injuries could occur.
NOTE
When driving with only 1 of the rear windows open, your ears might experience a
resonating sound. However, this does not indicate a problem. The sound can be reduced by
slightly opening a front window or by ch anging the size of the rear window opening.
▼Opening/Closing Windows
The window opens while the switch is pressed and it closes while the switch is pulled up
with the ignition switched ON. Do not open or
close three or more windows at the same
