Cargo and luggage
CAUTION
Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk.
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 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)
• Package tray
• Instrument panel
• Dashboard
Secure all items in the occupant compartment, as they may shift and injure
someone during sudden braking, sudden swerving or an accident.
Take notice of the following information about storage precautions,
cargo capacity and load.
Stow cargo and luggage in the trunk whenever possible.
Be sure all items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far
forward 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 back before washing the vehicle.
Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Turn the wipers off before washing the vehicle.
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.
Touch-up paint (if equipped)
Touch-up paint may be used to cover small chips or scratches.
Apply the paint soon after the damage occurs or corrosion may set in. To
apply the touch-up paint so it is hardly noticeable the trick is to apply it only
to the bare spots. Apply only the smallest amount possible and do not paint
the surface around the scratch or chip.
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
thoroughly 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 vehi-
cle body is cool.

Maintenance and care
IS F_EE
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 battery.
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:
Be sure the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning is
on and/or the coolant temperature is high. (P. 374)
CAUTION
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 Lexus
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire 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, Lexus
recommends that tire inflation pressure be checked once every two
weeks.
