• The outside temperature is low
• There are water droplets on the camera
• It is raining or humid
• Foreign matter (mud etc.) is adhering to the camera
• Sunlight or headlights are shining directly into the camera
• The vehicle is under fluorescent
lights, sodium lights, mercury
lights etc.
If this happens due to these causes,
it does not indicate a malfunction.
Back up while visually checking the
vehicle’s surroundings. (Use the

2724-7. Driving tips
PRIUS c_U
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic re ports
before leaving and avoid delays as much as possible. When drivi ng
in a traffic jam, gently release the brake pedal to allow the v ehicle 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 st op-
ping at a toll booth or similar, allow plenty of time to releas e the
accelerator and gently apply the brakes. A greater amount of el ec-
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 tempe rature 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 gasolin e engine will not automatically cut out
until it and the interior of the vehicle are warm, it will cons ume fuel.
Also, fuel consumption can be improved by avoiding overuse of t he
heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are app ro-
priate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.

●Use fluids that are appropriate t o 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 cha ins 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 fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent 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 ic e 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.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-
ditions.

4027-1. Maintenance and care
PRIUS c_U
NOTICE
●If the paint is chipped or scratched, have it repaired immediat ely.
● To prevent the wheels from corroding, remove any dirt and store in a place
with low humidity when storing the wheels.
■ Cleaning the exterior lights
● Wash carefully. Do not use organic substances or scrub with a h ard brush.
This may damage the surfaces of the lights.
● Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■ When using a high pressure car wash
● When washing the vehicle, do not spray the camera or its surrou nding
area directly with a high pressure washer. Shock applied from high pres-
sure water may cause the device to not operate normally.
● Do not bring the nozzle tip close to boots (rubber or resin man ufactured
cover), connectors or the following parts. The parts may be dam aged if
they come into contact with high-pressure water.
● Keep the cleaning nozzle at least 11.9 in. (30 cm) away from th e vehicle
body. Otherwise resin section, such as moldings and bumpers, ma y be
deformed and damaged. Also, do not continuously hold the nozzle in the
same place.
● Do not spray the lower part of the windshield continuously. If water enters
the air conditioning system intake located near the lower part of the wind-
shield, the air conditioning system may not operate correctly.
■ Roof molding (if equipped)
• Traction related parts
• Steering parts • Suspension parts
• Brake parts
Do not hold or pull a roof molding when
climbing onto the vehicle or shaking the
vehicle as the roof molding may become
disengaged and water may leak into the
vehicle.
