▼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 s
ystem to switch the
vehicle's drive mode. When the sport
mode is selected, v ehicle'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 selection 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 Information 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.

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
Castrol
® (U.S.A. only).


Only use SAE 0W-20 oil “Certified For
Gasoline Engines” by the American

Tires
▼Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with
different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-9) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always
inflate the tires to the correct
pressure:
Overinflation or
underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-9.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recom mended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification charts (page
9-9).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
