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 e nhanced. This provides
additional quick acceleration which may be needed to safely mak e maneuvers such as lane
changes, merging onto freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when driving on sli ppery roads such as wet or snow-covered roads.
It may cause tire slipping.
NOTE

increase fuel consumption. Mazda recommends that you cancel the sport mode on normal
