Automatic transmission
While the engine switch is in IGNITION ON mode, move the shift lever
with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: Shifting to the D position allows the system
to select a gear suitable for the driving
conditions. Setting the shift lever to the D position is recommended for normal driv-
ing.
*2: Selecting shift ranges using S mode rest ricts the upper limit of the possible gear
ranges, controls engine braking forces , and prevents unnecessary upshifting.

■Driving on a downhill
On declines, there may be case where the ve
hicle shifts down automatically to obtain
engine braking. As a result of the down shifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to

●If the temperature of the rain drop sensor is 194 F (90 C) or higher, or 5 F (-15 C) or
lower, the automatic operation may not occur. In this case, operate the wipers in any
mode other than “AUTO”.
