Cleaning and protecting the vehicle exterior
●
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 vehicle body is cool.
■
Automatic car washes
●
Fold the mirrors back before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●
Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
●
Rear spoiler may not be washable in some automatic car washes. There may also be an
increased risk of damage to vehicle.
■
High pressure car washes
●
Do not allow the nozzles of the car wash to come within close proximity of the windows.
●
Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■
Wheels (including surrounding parts)
●
Remove any dirt immediately by using a neutral detergent. Do not use hard brushes or
abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same mild
detergent and wax as used on the paint.

Notes for a smart access system with push-button start
●
If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. Place the key in a position 6 ft. (2 m) or more
separate from the vehicle while the vehicle is being washed. (Take care to ensure that
the key is not stolen.)

wash, a message may be shown on the multi-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.

When a wet rag or similar is held close to the raindrop sensor
●
If something bumps against the windshield
●
If you directly touch the raindrop sensor body or if something bumps into the raindrop
sensor
■
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
■
Precautions regarding the Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunction.
If this occurs, consult your Lexus dealer.

shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.

control system. Your vehicle may not pass the I/M test and may need to be
repaired. Contact your Lexus dealer to service the vehicle.
●
When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may not be com-
pletely set.

When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary malfunction
and your vehicle may not pass the I/M test.
The error code in the OBD system will not be cleared unless the vehicle is driven
40 or more times.
Contact your Lexus dealer to prepare the vehicle for re-testing.
Some states have vehicle emission inspection programs which include OBD
(On Board Diagnostics) checks. The OBD system monitors the operation of
the emission control system.

WARNING
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 com-
partment.
●
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 corro-
sive sulfuric acid.
■
When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the
electric cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. (
■
When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in
your eyes.
NOTICE
■
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.
