Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
Q When working on the engine compartment
O Keep hands, clothing and tools away from the moving fan and engine
drive belt.
O Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
O Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
O Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
O Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
O Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
Q Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
Q If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
Q If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

QBefore recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
O If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
O Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
Q After recharging/reconnecting the battery (vehicles with smart entry &
start system)
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P (automat ic transmission) or depress the brake
pedal with the shift lever in N (manual transmission).
Open and close any of the doors.
Restart the engine.
O 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.
O 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.
O 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.
Q If a symbol of a battery is shown on the multi-information display
There is a malfunction in the vehicle’s charging system.
Immediately stop the vehicle in a safe place and contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer. Continu-
ing to drive the vehicle may be dangerous.

AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. Make sure to observe the following precautions regarding
AdBlue™.
O AdBlue™ is consumed in the process of driving.
O When AdBlue™ is depleted, the engine cannot be restarted.
O 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.
QPossible 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.
*1: When the vehicle is used at high elevations and in low temperatures, the
amount of AdBlue™ that is consumed increases.
*2: During normal driving, 1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is con-
sumed approximately every 600 km (373 miles). Also, after a full refill, the
vehicle can be driven for approximately 10000 km (6214 miles) before all
AdBlue™ is depleted.

Maintenance and care
WARNING
QWhen inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
O Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
O Do not use tire sizes other than those recommended by Toyota.
O Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
O Do not mix summer, all season and snow tires.
O Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
NOTICE
Q Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
Q If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
QEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
O Reduced fuel economy
O Reduced driving comfort and poor handling
O Reduced tire life due to wear
O Reduced safety
O Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
Q Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
O Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation
pressure reading.
O Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
O It is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.
O Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. ( P. 639)
