For smooth operation, depress the
brake pedal and the lock release but-ton when shifting from N (Neutral) toa forward or reverse gear.
When stopped on an incline, do not
hold the vehicle with the engine
power. Use the service brake or the
parking brake.
Transaxle ranges
The indicator in the instrument clus-
ter displays the shift lever position
when the engine start/stop button is
in the ON position.
P (Park)
Always come to a complete stop
before shifting into P (Park). This
position locks the transaxle and pre-
vents the drive wheels from rotating.
Shifting into P (Park) while the vehi-
cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
If you have done all of the above
and still cannot shift the lever out of
P (Park), see "Shift-lock override" in
this chapter.
The shift lever must be in P (Park)
before turning the hybrid system off.
WARNING- Leaving
Vehicle
Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Do not use
the P position in place of the
parking brake. Always make
sure the shift lever is locked in
the P position and set the park-
ing brake fully. Unexpected and
sudden vehicle movement can
occur if these precautions are
not followed.
CAUTION- Transaxle
To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on. The transaxle may bedamaged if you shift into P(Park) while the vehicle is inmotion.

into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the hybrid system or turn the
ignition switch to the ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the
shift lever in the P (Park) position, a
chattering noise & vibration near the
shift lever may be heard. It is a nor-
mal condition. Shift-lock override

from the P (Park) position into R
(Reverse) position with the brake
pedal depressed, continue depress-
ing the brake, then do the following:
1. Place the engine start/stop button
in the LOCK/OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cov- ering the shift-lock release access
hole.
4. Insert a tool (e.g. flathead screw- driver) into the access hole and
press down on the tool.WARNING- Shifting from
park
