■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move. Always
change the shift position to P, and apply the parking brake when parked.
The following sounds or vibrations may occur when the hybrid system is operating and are
not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transaxle when the engine is started or stopped, or while
the engine is idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed
and accelerator is loosened.
●Other sounds, such as motors and mechanical noises, may be heard from the brake sys-
tem when the brake pedal is depressed.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of rear left seat-
back.
When driving in Eco drive mode, the fan noise may be louder than when driving nor-
mally.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light go off. If there is
only a small amount of fuel, the hybrid system may not be able to start.
(The minimum amount of fuel to add to make the low fuel level warning light go out is about
2.6 gal. [10 L, 2.1 Imp.gal.], when the vehicle is on a level surface. This value may vary when
the vehicle is on a slope.)

LKA (Lane-Keeping Assist) (If Equipped)
Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts the driver using
rapid beeping, indications on the multi-information display, and a sensory warning
* given
via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the cen-
ter of the lane.
Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance control mode of the
cruise control is set with vehicle speed above approx. 45 mph (approx. 72 km/h) and
while the lane departure warning function is active. When the lane keeping assist func-
tion is active, a slight steering torque will be applied, to help the driver maintain the vehi-
cle inside the lane.
■Tu r n i n g t h e L K A s y s t e m o n
The lane departure warning function and lane keeping assist function will be activated
depending on the recognition condition of lane markers, vehicle speed and the setting of
radar cruise control (vehicle-to-vehicle distance control mode).
Press the “LKA” switch to activate the sys-
tem.
“LKA” indicator will come on.
Press the switch again to turn the LKA
system off.
While driving on a freeway or motor highway that has lane markers, this system recog-
nizes the lanes using a camera as a sensor to assist the driver with staying in the lane. The
LKA system has two functions.

keeping assist function) are shown on the multi-information display to inform that the LKA
