2-1. Driving procedures
GS_HV_U (OM30B44U)
April 27, 2009 10:09 am
■When starting on an incline
The hill-start assist control may operate. (→P. 2 1 4 )
■For efficient use
●Put the shift lever into “D” when driving
In the “N” position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
●Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the traction motor without having to use
gasoline engine power.
●Avoid repeated acceleration
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Put the shift lever into “P” when parking
In the “N” position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the “N” position for an extended period of the time may
discharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
■Normal characteristics after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear sound
coming from under the vehicle for several minutes. This is because the fuel evapo-
ration leakage check is performed. It does not indicate a malfunction.

CAUTION
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to death or a
serious health hazard.
■When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle.
●If the brake actuator does not operate, do not follow other vehicles closely and
avoid downhill or sharp turns that require making.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if turning the hybrid system off.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 3 individual hydraulic systems: If one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
■If the vehicle becomes stuck or bogged
Do not spin the wheels recklessly when any of the tires is up in the air, or stuck in
sand or mud, etc. This may damage the drive system components or propel the
vehicle forward (or in another direction) and cause an accident.

Intuitive parking assist∗
∗: If equipped
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the mult i-information display, the touch screen,
and warning beeps.
The system may be used at speeds less than about 6 mph (10 km/h).
■ Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, and one in each corner of the bumper,
to detect obstacles in those areas.
The dual sensors detect obstacles ahead of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.
