The cruise control will cancel if the
vehicle speed decreases below 20 km/h
(12 mph) when the cruise control is
activated, such as when climbing a steep
grade.
The vehicle speed preset using the cruise
control is displayed in the instrument
cluster and the active driving display
(vehicles with activ e driving display).

▼ Changing the Set Vehicle Speed
Follow either of these procedures.
To increase/decrease speed using cruise
control switch
When the RES switch is pressed up (SET
+), the vehicle accelerates and when the
RES switch is pressed down (SET-), it
decelerates.
Press and release immediately: 1 km/h
(1 mph)
Press and hold: 10 km/h (5 mph)
NOTE
Even after releasing the RES switch, the
cruise control accelerates/decelerates
continuously until the set speed displayed
in the instrument clus
ter and on the active
driving display is reached. If you want to
stop accelerating/decel erating, change the
set speed or cancel the system (such as by
depressing the brake pedal).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press the
RES switch up (SET+) or down (SET-) at
the desired speed. If the switch is not
operated, the system returns to the set
speed after you release your foot from the
accelerator pedal.
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is on.
Greater speed will not interfere with or
change the set speed. Take your foot off
the accelerator to retu rn to the set speed.

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.
