●The vehicle is driven on a surface that is bright due to reflected light, etc.
●The vehicle is driven in an area where the brightness changes suddenly,
such as at the entrances and exits of tunnels, etc.
●Light from the headlights of an oncoming vehicle, the sun, etc., enters the
camera.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Driving
PRIUS +_OM_OM47D30E_(EE)
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Fuel consumption can be improved by avoiding overuse of the
heater.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
●Have a service technician inspect the condition of the 12-volt bat-
tery.
●Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
