Hill Descent Control*
The hill descent control is a system that
maintains a constant vehicle speed
when the vehicle descends a steep
slope, off-road or on a snowy road. As
the low speed can be maintained
without operating the accelerator
pedal or the brake pedal, the driver
can concentrate on the steering wheel
operation.
Warnings and Cautions
for Using the Hill Descent Control
WARNING
Do not rely completely on the hill
descent control.
If necessary, depress the brake pedal
on a slippery road surface such as
extremely steep slope s, icy roads, or
mud or gravel roads. Failure to
maintain a constant low speed may
result in an unexpected accident.
Always drive carefully.

How to Use the HillDescent Control
Using the Hill Descent Control
1. When the vehicle speed is about 25 km/h (15 mph) or slower, press the
hill descent control switch.
The hill descent control is operable,
and the hill descent control
indicator light (white)
turns on.
2. Depress the accelerator pedal or the brake pedal to drive the vehicle
at a speed between about 3 km/h
and 20 km/h (2 and 12 mph).
3. Release the accelerator pedal or the brake pedal when the desired
target speed is reached.
The hill descent control operates,
the hill descent control indicator
light (white)
changes to the hill
descent control indicator light
(green)
, and then the target
speed is displayed.
The brake lights turn on while the
hill descent control is operating.
NOTE
If the braking system is overheated
after using the hill descent control for
a long time, the operation of the hill
descent control may be temporarily
stopped. When the operation of the
hill descent control stops, a warning
sound is activated and the hill
descent control indicator light turns off.
The hill descent control may not be
available due to a system
malfunction in the following cases.
Have your vehicle inspected by an
Authorized Mazda Dealer.
The hill descent control indicator
light does not turn on even if the
hill descent control switch is
pressed.
The TCS/DSC operation indicator
light turns on.
The hill descent control is not
available while Mazda Radar Cruise
Control (MRCC) or Cruising & Traffic
Support (CTS) is operating.

(SPORT Mode)
(NORMAL Mode)
(EV Mode)
(OFF-ROAD Mode)
NOTE
TOWING mode can be selected only
when electrically connected to the
trailer using a Mazda genuine trailer
hitch. In addition, it may take some
time until the connection is detected
and TOWING mode is displayed.
Consult an Authorized Mazda Dealer
for details.
Depending on driving conditions
when selecting TOWING mode/
SPORT mode/OFF-ROAD mode, the
vehicle may perform shift-down or
accelerate slightly.
When SPORT mode/OFF-ROAD
mode is selected, driving the vehicle
at higher engine speeds increases
and fuel economy may worsen.
Canceling SPORT mode/OFF-ROAD
mode during normal driving is
recommended.
When setting the Mazda Radar
Cruise Control (MRCC) while driving
in SPORT mode, the mode is
switched to NORMAL mode. In
addition, while the MRCC is being
used, the mode cannot be switched
to SPORT mode.
Switching to EV mode may not be
possible depending on the driving
operations, driving conditions, and
high voltage battery condition.
When the system determines that
the engine needs to be started while
the vehicle is being driven in EV
mode, the mode is switched to
NORMAL mode.
The remaining distance-to-full
discharge for EV mode may
decrease, even when the vehicle is
being driven in a mode other than
EV mode.
The maximum speed in EV mode is
140 km/h (86 mph).
The drive mode cannot be switched
in the following cases.
The Antilock Brake System (ABS) is
operating.
The Traction Control System (TCS)
is operating.
The Dynamic Stability Control
(DSC) is operating.
The steering wheel is being
operated abruptly.
The driving mode in which the
display in the instrument cluster is
grayed out cannot be selected.
When the vehicle power is switched
OFF, the mode returns to NORMAL
mode. However, TOWING mode
before switching the vehicle power
OFF is maintained only when the
trailer is connected in TOWING
mode.

Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensor
Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brake and reduce
the vehicle speed.
Do not ignore the TPMS warning light
when it is turned on or flashing.
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.
