face
■ If VSC is disabled

If you notice any symptoms
If you notice any of the followi
ng symptoms, refer to the likel y cause
and the solution, and re-check.
If the symptom is not resolved by the solution, have the vehicl e
inspected by your Toyota dealer.
Things you should know
Likely causeSolution
The image is difficult to see
• The vehicle is in a dark area
• The temperature around the lens
is either high or low
• 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
monitor again once conditions have
been improved.)
To adjust the image on the rear view
monitor system screen. ( P. 292)
 The image is blurry
Dirt or foreign matter (such as water
droplets, snow, mud etc.) is adher-
ing to the camera.Flush the camera with a large quan-
tity of water and wipe the camera
lens clean with a soft and wet cloth.
The image is out of alignment
The camera or surrounding area has
received a strong impact.Have the vehicle inspected by your
Toyota dealer.
The fixed guide lines are very far out of alignment
• The vehicle is tilted (there is a
heavy load on the vehicle, tire
pressure is low due to a tire punc-
ture, etc.)
• The vehicle is used on an incline.If this happens due to these causes,
it does not indicate a malfunction.
Back up while visually checking the
vehicle's surroundings.
The camera position is out of align-
ment.Have the vehicle inspected by your
Toyota dealer.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if di fferent tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.

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.

2764-7. Driving tips
PRIUS c_U
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire cha ins in a safe location.
●Install tire chains on the front tires only. Do not install tir e chains on the
rear tires.
●Install tire chains on front tires as tightly as possible. Reti ghten chains
after driving 1/4  1/2 mile (0.5  1.0 km).
●Install tire chains following th e instructions provided with th e tire chains.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the size specified.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tir e chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that v ehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert) system.
