When using a car wash
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not
stolen.)
Set the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 1 2 9 )
Aluminum wheels
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.
Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.
Bumpers
Do not scrub with abrasive cleaners.
Front side windows water-repellent coating
The following precautions can extend the effectiveness of the water-repel-
lent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long
period.
Clean the windows with a soft, damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning
the windows.
• Do not use any metallic objects to remove condensation build up.
When the water-repellent performance has become insufficient, the coating
can be repaired. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.

Observe the following precautions in order to retain the rain-clearing proper-
ties of the mirrors:

CAUTION
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
When cleaning the windshield (with rain-sensing windshield wipers)

Precautions regarding the exhaust pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become
quite hot.
When washing the vehicle, be careful not to touch the pipes and diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear
bumper diffusers can cause burns.
Set the wipers to the intermittent wind-
shield wipers. (P. 245)
If AUTO mode is selected, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.

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
The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P.
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.

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.
