Maintenance and care
■When using a car wash
If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correc-
tion procedures to wash the vehicle:
●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.)
●Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. (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 and side moldings
Do not scrub with abrasive cleaners.

6-2. Maintenance
■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair shop
other than a Lexus dealer performs repairs, confirm the warranty coverage.
■Reset the maintenance data (U.S.A. only)
After the required maintenance is performed according to the maintenance sched-
ule, please reset the maintenance data.
To reset the data, follow th e procedure described below:
Switch the display to the trip meter “A” ( P. 94) when the engine
is running .
Turn the “START STOP ENGINE” <“POWER”> switch off.
While pressing the “ODO TRIP” button ( P. 94), turn the “START STOP
ENGINE” <“POWER”> switch to the IGNITION ON mode (do not start
the engine because otherwise the reset mode will be canceled).
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialist s and are kept up to date with the latest
service information. They are well informed about the operations of all systems on
your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle
is under warranty, your Lexus dealer will promptly take care of it. The message shown in the illustration will
appear on the display.
Continue to press and hold the button until
the trip meter displays “000000”.
