2023 MAZDA MODEL CX-50 fuel

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 Lid and Cap
▼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.

Trailer Towing (U.S.A. and Canada)
▼Trailer Towing (U.S.A. and Canada)
Your Mazda was designed and built primarily to carry passengers and cargo.
If you tow a trailer, follow these instructions because driver and passenger safety
depends on proper equipment and safe driving habits. Towing a trailer will
affect
handling, braking , durability, performance, and fuel economy.
Never overload your vehicle or trailer. Co nsult an Authorized Mazda Dealer if you
need further details.
CAUTION
Do not tow a trailer during the first 1,000 km (600 miles) of your new Mazda. If you
do, you may damage the engine, transmission, differential, wheel bearings, and
other power-train components.
NOTE
When towing, use of gasoline with a octane rating of 91 or higher is
recommended.
Your vehicle is equipped with a Mazda intelligent Drive Select (Mi-Drive) towing
mode* which enhances vehicle stab ility when towing a trailer.
Refer to Mazda intelligent Drive Select (Mi-Drive) (AWD) on page 4-83.
When towing a trailer, do not use the following safety systems (If a Mazda genuine
trailer hitch is used, these systems are automatically turned off):
Blind Spot Monitoring (BSM)Rear Cross Traffic Alert (RCTA)Smart Brake Support [Rearward detection function]Smart Brake Support [Rear crossing]Parking Sensor System (Rear)Blind Spot Assist of Emergency Lane Keeping (ELK)

TTW and GCWR
The total trailer weight (TTW), gross comb
ination weight rating (GCWR), gross axle
weight rating (GAWR), trailer load, and trailer tongue load must be within the
prescribed limits.
The total trailer weight (TTW) is the sum of the weights of the trailer load (trailer
weight plus cargo), trailer hitch, 2 passengers, and vehicle load (baggage, food,
camp gear, etc.). Never allow the total trailer weight (TTW) to exceed
specifications in the Trailer Towing-Load Table.
The maximum GCWR is the combination weight of the trailer and load plus the
