▼Gear Shift Indicator (GSI)
The GSI supports you to obtain optimum
fuel economy and smooth driving. It
displays the selected gear position in the
instrument cluster as well as notifies the
driver to change to the most suitable gear
position corresponding to the actual
driving condition.

1. Selected gear position
2. Suitable gear position
Indication
Condition
Numeral The selected gear
position is dis‐
played.
and numeral Shift up or down to the indicated
gear position is
recommended.
CAUTION
Do not rely solely on the shift-up/
shift-down recommendations by
indications. The actual driving situation
might require shift operations different
from indication. To avoid the risk of
accidents, the road and traffic conditions
have to be judged correctly by the driver
before shifting.
NOTE
The GSI turns off when the following
operations are performed.
The vehicle is stopped.
The vehicle is put in neutral.
The vehicle is driven in reverse.
The clutch is not fully engaged when
accelerating from a stop.
The clutch pedal remains depressed for
2 seconds or longer while driving.
▼Recommendations for Shifting
Upshifting
For normal acceleration, Mazda
recommends these shift points:
(U.S.A. and Canada)
Gear
Vehicle speed
1 to 2 24 km/h (15 mph)
2 to 3 42 km/h (26 mph)
3 to 4 60 km/h (37 mph)
4 to 5 75 km/h (46 mph)
5 to 6 79 km/h (49 mph)
For cruising, Mazda recommends these
shift points:
(U.S.A. and Canada)
Gear Vehicle speed
1 to 2 13 km/h (8 mph)
2 to 3 29 km/h (18 mph)
3 to 4 49 km/h (30 mph)
4 to 5 63 km/h (39 mph)
5 to 6 70 km/h (43 mph)
Downshifting
When you must slow down in heavy
traffic or on a steep upgrade , downshift
before the engine starts to overwork. This
reduces the chance of stalling and gives
better acceleration when you need more
speed.
On a steep downgrade , downshifting
helps maintain safe speed and prolongs
brake life.

Drive Selection*
▼Drive Selection
Drive selection is a system to switch the
vehicle's drive mode. When the sport
mode is selected, vehicle's response
against accelerator operation is enhanced.
This provides additional quick
acceleration which may be needed to
safely make maneuvers such as lane
changes, merging onto freeways, or
passing other vehicles.
CAUTION
Do not use the sport mode when driving on
slippery roads such as wet or snow-covered
roads. It may cause tire slipping.
NOTE
When the sport mode is selected, driving
at higher engine speeds increases and it
may increase fuel consumption. Mazda
recommends that you cancel the sport
mode on normal driving.
Drive mode cannot be switched in the
following conditions:
ABS/TCS/DSC is operating
Cruise control* is operating.
The Mazda Radar Cruise Control with
Stop & Go function (MRCC with Stop
& Go function) System
* is operating.
Traffic Jam Assist (TJA)* is operating.
Steering wheel is being operated
abruptly
▼Drive Selection Switch
Press the drive sele
ction switch forward
(SPORT) to select the sport mode.
Pull the drive selecti on switch back (OFF)
to cancel the sport mode.

NOTE
In the following cases, the drive
selection is canceled.
The ignition is switched OFF.
Cruise Control is set.
Mazda Radar Cruise Control with
Stop & Go function (MRCC with Stop
& Go function) is set.
Traffic Jam Assist (TJA) is set.
Depending on the driving conditions
when sport mode is selected, the vehicle
may perform shift-down or slightly
accelerate.

Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified value, the system notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data sent
from the tire pressure s
ensors installed on
each wheel via radio signal is received by
the receiver unit in t he vehicle to monitor
the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures can
be checked using the center display.
Refer to the Vehic le Status Monitor
section in the Mazda Connect Owner's
Manual.
NOTE
When the ambient temperature is low,
the tire temperatures also decrease. If
the tire temperatures decrease, the air
pressure in the tires will also decrease
which could turn on the TPMS warning
light.
Before driving, visually inspect the tires
for abnormalities. Additionally, inspect
the tire pressures monthly. A digital type
air pressure gauge is recommended for
inspecting the tire pressures.
The TPMS is not a substitute for your own
periodic inspection of the tires. Always
inspect the tires yourself periodically.
CAUTION
 Each tire, includ ing the spare (if
provided), should be checked monthly
when cold and inflated to the
inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.

Owner MaintenancePrecautions
▼Owner Maintenance Precautions
The owner or a qualified service
technician should make these vehicle
inspections at the i
ndicated intervals to
ensure safe and dependable operation.

Bring any problem to the attention of an
Authorized Mazda Dealer or qualified
service technician as soon as possible.
When Refueling
Brake and clutch fluid level (page
6-19)
Engine coolant level (page 6-17)
Engine oil level (page 6-16)
Washer fluid lev el (page 6-19)
At Least Monthly
Tire inflation pressures (page 6-31)
At Least Twice a Year (For Example,
Every Spring and Fall)
You can do the following scheduled
maintenance items if you have some
mechanical ability and a few basic tools
and if you closely follow the directions in
this manual.
Engine coolant (page 6-17)
Engine oil (page 6-16)

Improper or incomplete service may result
in problems. This section gives
instructions only for items that are easy to
perform.

As explained in the Introduction (page
6-2), several procedures can be done only
by a qualified service technician with
special tools.

Improper owner maintenance during the
warranty period may affect warranty
coverage. Refer to Introduction (page 6-2)
for owner's responsibility in protecting
your investment. For details, read the
separate Mazda Warranty statement
provided with the vehicle. If you are
unsure about any servicing or maintenance
procedure, have it done by an Authorized
Mazda Dealer.

There are strict environmental laws
regarding the disposal of waste oil and
fluids. Please disp ose of your waste
properly and with due regard to the
environment.

We recommend that you entrust the oil and
fluid changes of your vehicle to an
Authorized Mazda Dealer.
WA R N I N G
Do not perform maintenance work if you
lack sufficient knowledge and experience
or the proper tools and equipment to do
the work. Have maintenance work done by
a qualified technician:
Performing maintenance work on a vehicle
is dangerous if not done properly. You can
be seriously injured while performing some
maintenance procedures.

Engine Oil
▼Engine Oil
NOTE
Changing the engine oil should be
performed by an Authorized Mazda
Dealer.
Refer to Introduction (page 6-2) for
owner's responsibility in protecting your
investment.
▼Recommended Oil
U.S.A., Canada
Use ILSAC GF-V or higher/ SAE
0W-20 engine oil.
Mazda Genuine Oil is used in your Mazda
vehicle. Mazda Genuine 0W-20 Oil is
required to achie
ve optimum fuel
economy.

For maintenance service, Mazda
recommends Mazda Genuine Parts and
Oil.

Only use SAE 0W-20 oil “Certified For
Gasoline Engines” by the American
Petroleum Institute (API).
Oil with this tradem ark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International
Lubricant Standardization and Approval
Committee (ILSAC), comprised of U.S.
and Japanese automobile manufacturers.

Except U.S.A., Canada
Use SAE 5W-30 engine oil.
Oil container labels provide important
information.
A chief contribution th is type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
