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.Tra
ffic Jam Assist (TJA) is operating.Steering wheel is being operated
abruptly
▼ Drive Selection Switch
Press the drive selection 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.Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function) System/cruise
control is set.
Tra
ffic Jam Assist (TJA) is set.Depending on the driving conditions
when sport mode is selected, the
vehicle may perform shift-down or
slightly accelerate.

i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety
and driver support systems which
make use of cameras and sensors. The
systems consist of active safety and
pre-crash safety systems.
These systems are designed to assist
the driver in safer driving by reducing
the load on the driver and helping to
avert collisions or reduce their severity.
However, because each system has its
limitations, always drive carefully and
do not rely solely on the systems.
▼Active Safety Technology
Active Safety Technology supports safer
driving by helping the driver to
recognize potential hazards and avert
accidents.
