4807-1. Maintenance and care
CT200h_OM_OM76102E_(EE)
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.
Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface
scratches caused in a car wash etc.
The coating lasts for 5 to 8 years after the coating has been performed.
The restoration time differs depending on the depth of the scratch and outside
temperature. The restoration time may become shorter when the coating is
warmed by applying warm water.
Deep scratches caused by keys or coins cannot be restored.
Do not use wax that contain abrasives.
Automatic car washes
Fold the mirrors 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 properly.
Perform the following to protect the vehicle and maintain it in prime con-
dition:

Maintenance and care

Note for a smart entry & start system (if equipped)
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 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.)
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-repellent
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.
Restoration work for rain clearing effect of the rain clearing mirror (if equipped)
The rain clearing effect on the mirror surface will gradually recover after expo-
sure to sunlight (P. 176). However, if you want to restore the effect immedi-
ately, conduct the following procedures:
Apply water to the mirror surface to wash the dirt away from it.
Remove the dirt by using a clean, soft and wet cloth.
Clean the mirror surface with glass cleaner or detergent. When detergent is
used, rinse the mirror surface with a lot of water.
Wipe water on the mirror surface by using a clean and soft cloth, ect.
Park your vehicle outdoors to expose the mirror surface to sunlight for about 5
hours. (The restoration time differs depending on the amount and type of dirt.)

Maintenance and care
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following precautions before recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to discon-
nect the ground cable.
Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
Unlocking the doors using the smart entry & start system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use the
wireless remote control or the mechanical key to lock/unlock the doors.
Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it was
in before the 12-volt battery was disconnected. Make sure to turn off the power
before disconnect the 12-volt battery. Take extra care when connecting the 12-
volt battery if the power switch mode prior to discharge is unknown.
Restart the hybrid system, depress the brake pedal, and confirm that it is possi-
ble to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
