◆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.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances wi ll cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

●Use fluids that are appropriate to the prevailing outside tempera-
tures. • Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspec t 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 accordin g 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.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Winter driving tips

●Install tire chains following the instructions provided with the tire chains.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause 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 accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire 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 vehicle con-
trol is maintained.

3265-8. Connecting Bluetooth® (Multimedia system)
PRIUS c_U (OM52J11U)
To turn auto connection mode on, set “Bluetooth* Power” to on.
( → P. 328)
When you register a phone, auto connection will be activated. Always
set it to this mode and leave the Bluetooth
® phone in a place where a
connection can be established.
When the engine switch is turned to the “ACC” or “ON” position (vehicles
without a smart key system) or the “POWER” switch is turned to ACCES-
SORY or ON mode (vehicles with a smart key system), the system will
search for a nearby cellular phone you have registered.
Next, the system automatically connects with the most recent of the
phones connected to in the past. Then, the connection result is displayed.
*: Bluetooth is a registered trademark of Bluetooth SIG, Inc.
When auto connection has failed or “Bluetooth* Power” is turned off,
you must connec t the Bluetooth® device manually.

■Reconnecting a Bluetooth® phone
If the system cannot connect due to poor signal strength with the engine
switch is turned to the “ACC” or “O N” position (vehicles without a smart key
system) or the “POWER” switch is turned to ACCESSORY or ON mode (vehi-
cles with a smart key system), the system will automatically attempt to recon-
nect.
If the phone is turned off, the system will not attempt to reconnect. In this

3806-1. Using the air conditioning system and defogger
PRIUS c_U (OM52J11U)■
Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated air mode will also cool the vehicle
interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ When the outside temperature exceeds 75 °F (24 °C) and the air condition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine switch
is turned to the “ON” position (vehicles without a smart key system) or the
“POWER” switch is turned to ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pressing .
■ When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is pressed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.

■The outside temperatur e is displayed when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The “POWER” switch is in ON mode.
■ Outside temperature display
■ Display
In the following situations, the correct outside temperature may not be \
dis-
played, or the display may take longer than normal to change:
●When the vehicle is stopped, or moving at low speeds (less than 16 mph [25
km/h])
● When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
■ When “ − −” or “E” is displayed
The system may be malfunctioning. Take your vehicle to your Toyota dealer. The outside temperature is shown on the
multi-information display when the steer-
ing wheel climate remote control
