Shift position indicator
The position of the frame on the shift position indicator changes in
accordance with the current shift position.
When any shift position other than D or B is selected, the arrow toward
B and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position indica-
tor provided on the instrument cluster.
■ Shift position purpose
*: For good fuel economy and noise reduction, the D position should usu-
ally be used.

When driving
■
Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
■ Automatically P position selection function
When the shift position is in a position other than P, pressing the “POWER”
switch with the vehicle stopped completely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
■ If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. ( P. 601)
■ About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
●When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
● The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, shift the shift position to D.
■ When driving with cruise control or radar cruise control activated
Even if switching the driving mode to power mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
radar cruise control will not be canceled.

NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 607)

Maintenance and care
Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning off the hybrid system, wait more than 5 minutes
for the oil to drain back in to the bottom of the engine.
Holding a rag under the end, pull
the dipstick out.
Wipe the dipstick clean.
Flat dipstick: Reinsert the dipstick fully. Non-flat dipstick: Reinsert the
dipstick fully with its protruding
areas ( in the illustration)
pointing towards the engine.
Holding a rag under the end, pull the dipstick out and check
the oil level.

■ Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
