CAUTION
  Before opening the liftgate/boot
lid, remove any snow and ice
accumulation on it. Otherwise, the
liftgate/boot lid could close under the
weight of the snow and ice resulting
in injury.
  Be careful when opening/closing
the liftgate/boot lid during strong
winds. If a strong gust blows against
the liftgate/boot lid, it could close
suddenly resulting in injury.
  Fully open the liftgate/boot lid and
make sure that it stays open. If the
liftgate/boot 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/boot,
turn off the engine. Otherwise, you
could get burned by the heat of the
exhaust gas.
  Be careful not to apply excessive
force to the damper stay on the
liftgate such as by putting your hand
on the stay. Otherwise, the damper
stay may bend and affect the liftgate
operation.

Fuel and Engine Exhaust Precautions
Fuel Requirements (MZR 1.6, SKYACTIV-G 1.5, SKYACTIV-G 2.0)
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
The vehicle will perform best with fuel listed in the table.

Before Driving
Fuel and Emission
CAUTION
  USE ONLY UNLEADED FUEL.  Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
  The use of E10 fuel with 10 % ethanol in Europe is safe for your vehicle. Damage to
your vehicle may occur when ethanol exceeds this recommendation.
  Never add fuel system additives, otherwise the emission control system could be
damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer
for details.
Fuel Requirements (SKYACTIV-D 2.2)
The vehicle will operate effi ciently on diesel fuel with specifi cation EN590 or the
equivalent.
CAUTION
  Never use fuel other than specifi cation EN590 or the equivalent for your vehicle. Use
of petrol or paraffi n in diesel engines will result in engine damage.

 Never add fuel system additives. Otherwise, the emission control system could be
damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer
for details.
NOTE
When refuelling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.

Emission Control System (MZR 1.6, SKYACTIV-G 1.5, SKYACTIV-G 2.0)
This vehicle is equipped with an emission control system (the catalytic converter is
part of this system) that enables the vehicle to comply with existing exhaust emissions
requirements.
WARNING
Never park over or near anything fl ammable:
Parking over or near anything fl ammable, such as dry grass, is dangerous. Even with
the engine turned off, the exhaust system remains very hot after normal use and could
ignite anything fl ammable. A resulting fi re could cause serious injury or death.
CAUTION
Ignoring the following precautions could cause lead to accumulate on the catalyst inside
the converter or cause the converter to get very hot. Either condition will damage the
converter and cause poor performance.
 
 USE ONLY UNLEADED FUEL. 
 Do not drive your Mazda with any sign of engine malfunction. 
 Do not coast with the ignition switched off. 
 Do not descend steep grades in gear with the ignition switched off. 
 Do not operate the engine at high idle for more than 2 minutes. 
 Do not tamper with the emission control system. All inspections and adjustments must
be made by a qualifi ed technician.

 Do not push-start or pull-start your vehicle.

Before Driving
Fuel and Emission
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 contains carbon monoxide (CO), which is
colourless, odourless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside the vehicle, keep all windows fully open and
contact an expert repairer, we recommend an Authorised Mazda Repairer 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 exhaust 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 Flap and Cap
WARNING
When removing the fuel-fi ller 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-fi ller cap is removed too
quickly.
Before refuelling, stop the engine, and
always keep sparks and fl ames away
from the fi ller neck:
Fuel vapour is dangerous. It could be
ignited by sparks or fl ames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
fi ller cap or not using a fuel-fi ller cap
may result in a fuel leak, which could
result in serious burns or death in an
accident.
Do not continue refuelling after
the fuel pump nozzle shuts off
automatically:
Continuing to add fuel after the fuel
pump nozzle has shut off automatically
is dangerous because overfi lling the
fuel tank may cause fuel overfl ow or
leakage. Fuel overfl ow and leakage
could damage the vehicle and if the
fuel ignites it could cause a fi re and
explosion resulting in serious injury or
death.
CAUTION
Always use only a designated Mazda
fuel-fi ller cap or an approved equivalent,
available at an expert repairer, we
recommend an Authorised Mazda
Repairer. The wrong cap can result in
a serious malfunction of the fuel and
emission control systems.
Fuel-Filler Flap
To open, pull the remote fuel-fi ller fl ap
release.
To close, press the fuel-fi ller fl ap until it
locks securely.

Mirrors
WARNING
Do not touch a power fold-in mirror
while it is moving:
Touching the power fold-in mirror
when it is moving is dangerous. Your
hand could be pinched and injured or
the mirror could be damaged.
Use the power fold-in switch to set the
mirror to the on-road position:
Setting the power fold-in mirror to the
on-road position by hand is dangerous.
The mirror will not lock in position and
will prevent effective rearview visibility.
Only operate the power fold-in mirror
with the vehicle safely parked:
Operating the power fold-in mirror
while the vehicle is moving is
dangerous. Wind blast on the mirror
will cause them to collapse and you will
be unable to return it to the on-road
position, preventing rearview visibility.
Engine-off outside mirror operation
*
The outside mirrors can be operated for
about 40 seconds after the ignition is
switched from ON to off with all doors
closed. If any door is opened, the outside
mirrors will stop operating.
Rearview Mirror
WARNING
Do not stack cargo or objects higher
than the seatbacks:
Cargo stacked higher than the
seatbacks is dangerous. It can block
your view in the rearview mirror, which
might cause you to hit another car
when changing lanes.
Rearview mirror adjustment
Before driving, adjust the rearview mirror
to centre on the scene through the rear
window.
NOTE
For the manual antidazzle mirror,
perform the adjustment with the
antidazzle lever in the day position.
