2023 TOYOTA 4RUNNER fuel

2064-2. Driving procedures
4RUNNER (U)
*1: To improve fuel efficiency and reduce noises, set the shift lever in the D
position for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible
gear ranges, controls engine braking forces, and prevents unnec essary
upshifting
When the shift lever is in the S position, the shift lever can be oper-
ated as follows:
Upshifting
Downshifting
The initial shift range in S mode is set automatically to “4” a ccording to
vehicle speed. However, the ini tial shift range may be set to “3” if AI-
SHIFT has operated while the shif t lever was in the D position.
(  P. 207)
■Shift ranges and their functions
You can choose from 5 leve ls of engine braking force.
A lower shift range will provide greater engine braking force t han a
higher shift range, and the engine speed will also increase.

■Daytime running light system
●Vehicles with a headlight high beam/daytime running lights: The daytime
running lights illuminate using the same lights as the headligh t high beam
and illuminate dimmer than the headlight high beam.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the , (type A only),
* (type B
and C) position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, eve n if the park-
ing brake is set again.
Type A and B: Daytime running lights can be turned off by opera ting the
switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

4-4. Refueling
●Close all the doors and windows, and turn the engine switch off.
● Confirm the type of fuel.
■Fuel types
P. 534
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If the malfunction indicator lamp illuminates
The malfunction indicator lamp may illuminate erroneously if re fueling is per-
formed repeatedly when the fuel tank is nearly full.
Opening the fuel tank cap
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle

2304-4. Refueling
4RUNNER (U)
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cau se injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission c ontrol
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

3465-1. Using the air conditioning system and defogger
4RUNNER (U)
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
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 en gine switch
is turned to IGNITION ON mode.
● It is possible to switch to outside air mode at any time by pre ssing
.
■When the indicator light on flashes
Press
to turn off the cooling and dehumidification function and turn it on
again. There may be a problem in the air conditioning system if the indicator
light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.

● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting, outside temperature, pressure, engine cool ant tem-
perature or inside temperature.

■When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is pre ssed.
■ When driving on dusty roads
