Cargo and luggage
CAUTION
Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment.
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions. 
Failing to do so may result in death or serious injury.
Do not place cargo or luggage in or on the following locations as the item
may get under the brake or accelerator pedal and prevent the pedals from
being depressed properly, block the driver’s vision, or hit the driver or pas-
sengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid
Do not stack anything in the luggage compartment higher than the seat-
backs.
Such items may be thrown about and possibly injure people in the vehicle
during sudden braking or in an accident.
Take notice of the following information about storage precautions,
cargo capacity and load.
Stow cargo and luggage in the luggage compartment whenever
possible.
Be sure all items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
For better fuel economy, do not carry unnecessary weight.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Automatic car washes
Fold the mirrors and remove the antenna before washing the vehicle.
Start washing from the front of the vehicle. Make sure to re-install the
antenna and extend the mirrors before driving.
Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Rain-sensing windshield wipers (if equipped): Turn the wipers off before
washing the vehicle. (P. 219)
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity
of the windows. 
Before car wash, check that the fuel filler door on your vehicle is closed
properly.
Perform the following to protect the vehicle and maintain it in prime
condition.
Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any
dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

Maintenance and care
iQ_WE_74014E
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
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.
Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
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, see a doctor.
When working near the electric cooling fan or radiator grille
Vehicles without smart entry & start system:
Be sure the engine switch is in the LOCK position.
With the engine switch in the ON position, the electric cooling fan may
automatically start to run if the air conditioning system is on and/or the
coolant temperature is high. (P. 342)
Vehicles with smart entry & start system:
Be sure the “ENGINE START STOP” switch is in the OFF.
With the “ENGINE START STOP” switch in the IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning
system is on and/or the coolant temperature is high. (P. 342)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 455)

Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Vehicles without smart entry & start system
Turn the engine switch to the ACC or LOCK position.
Restart the engine.
Vehicles with smart entry & start system
Press the “ENGINE START STOP” switch to change to the
ACCESSORY mode or OFF.
Restart the engine.
NOTICE
Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.
