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.

Fuel and Emission
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 and Emission
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.

Steering Wheel
Steering Wheel
WARNING

accident.
Steering Wheel Adjustment

steering wheel:
1. Stop the vehicle, and then pull down
the lock release lever under the steering
column.

Mirrors
Mirrors
Before driving, adjust the inside and
outside mirrors.
Outside Mirrors
WARNING
Be sure to look over your shoulder
before changing lanes:
Changing lanes without taking
into account the actual distance of
the vehicle in the convex mirror is
dangerous. You could have a serious
accident. What you see in the convex
mirror is closer than it appears.
NOTE
(Driver's Side Wide Angle Mirror * )
 
 The wide angle mirror has two
curvatures on its surface separated
by a region line into outer and
inner regions. The inner region is
a standard convex mirror whereas
the outer region allows for a wider
range of visibility within the same
sweep. This combination allows for
better assurance when making lane
changes.

Region line
  The perceived distance of objects
in the outer and inner regions of
the wide angle mirror is different.
Objects appearing in the outer region
are actually further away than they
are in the inner region.
