Engine oil consumption

A certain amount of engine oil will be consumed while driving. In the following
situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.

●

When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine

●

If low quality oil or oil of an inappropriate viscosity is used

●

When driving at high engine speeds or with a heavy load, when towing, or
when driving while accelerating or decelerating frequently

●

When leaving the engine idling for a long time, or when driving frequently
through heavy traffic

■

After changing the engine oil (1GD-FTV engine only)

The oil maintenance data should be reset. Perform the following procedures:



Vehicles with the multi-information display type A
Switch the display to the trip meter “A” when the engine is running.
(

cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.

●

Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer, service station or auto parts store for information
concerning recycling or disposal.

●

Do not leave used engine oil within the reach of children.

For more details about coolant, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.

■

If the coolant level drops within a short time of replenishing

Visually check the radiator, hoses, engine coolant reservoir cap, radiator cap
(if equipped), intercooler coolant reservoir cap (if equipped), drain cock and
water pump. If you cannot find a leak, have any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer test the caps and check for
leaks in the cooling system.

Check the radiator, condenser and intercooler (if equipped) and clear
any foreign objects. If any of the above parts are extremely dirty or
you are not sure of their condition, have your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

WARNING

■

When the engine is hot

Do not remove the radiator cap (if equipped), or the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

NOTICE

■

When adding coolant

Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.

■

If you spill coolant

Be sure to wash it off with water to prevent it from damage to parts or paint.

Radiator, condenser and intercooler

WARNING

■

When the engine is hot

Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.

Handling of the sub battery (if equipped)

●

Vehicles with a sub battery have the same 12-volt specification as vehicles
without a sub battery.

●

When replacing the sub battery, replace it with a battery that is the same
brand and specification as the previous one, and replace the sub battery at
the same time as the main battery.

●

When disconnecting, be sure to disconnect both negative terminals on the
two batteries.

■

Before recharging

When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:

●

If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.

●

Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.

■

After recharging/reconnecting the battery (vehicles with a smart entry &
start system)

Vehicles with the steering lock system: The engine may not start. Follow the
procedure below to initialize the system.

Shift the shift lever to P (automatic transmission) or depress the brake
pedal with the shift lever in N (manual transmission).
Open and close any of the doors.
Restart the engine.

●

Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.

●

Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.

●

The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■

Emergency measures regarding electrolyte

●

If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.

●

If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.

●

■

Using the gauge (if equipped)

The washer fluid level is checked by
observing the position of the level on the
liquid covered holes in the gauge.
If the level falls below the second hole
from the bottom (“LOW” position), refill the
washer fluid.

WARNING

■

When adding washer fluid

Do not add washer fluid when the engine is hot or running as washer fluid
contains alcohol and may catch fire if spilled on the engine etc.

NOTICE

■

Do not use any fluid other than washer fluid

Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as
damaging the pump leading to problems of washer fluid not spraying.

■

Diluting washer fluid

Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bot-
tle.

The water in the fuel filter must be drained immediately if the following
symptom occurs:



Vehicles with the multi-information display type A

The fuel system warning light flashes and buzzer sounds or the fuel
filter warning light comes on.



Vehicles with the multi-information display type B

When the warning message “Drain Water from Fuel Filter” appears on
the instrument cluster and buzzer

sounds.

: On some models

Remove the drain plug from the clamp and place a small tray to
catch the water.
Perform the draining as shown in the illustration.

Turn the drain plug about 2-
2-1/2 turns.

Loosening more than this will
cause water oozing from around
the drain plug.

Operate the priming pump
until the fuel begins to run
out.

After draining, retighten the drain plug. Do not use a tool.

AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. Make sure to observe the following precautions regarding
AdBlue™.

●

AdBlue™ is consumed in the process of driving.

●

When AdBlue™ is depleted, the engine cannot be restarted.

●

When AdBlue™ needs to be refilled, have it refilled at any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

It may be a criminal offence to use a vehicle that does not consume
any reagent if it is required for the reduction of emissions.

■

Possible driving range

The amount of AdBlue™ that is consumed while driving differs
according to the driving conditions and driving environment. When
the amount of AdBlue™ that is consumed increases, the possible
driving range until it is necessary to refill AdBlue™ decreases.

: When the vehicle is used at high elevations and in low temperatures, the

amount of AdBlue™ that is consumed increases.

: During normal driving, 1 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed

approximately every 700 km (435 miles). Also, after a full refill, the vehi-
cle can be driven for approximately 8000 km (4971 miles) before all
AdBlue™ is depleted.
