6-1. Maintenance and care
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 from when the vehicle is delivered from the plant.
●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, co ins, etc. 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 (if equipped) may not be wa shable in some automatic car washes.
There may also be an increased risk of damage to vehicle.
Perform the following to protect th e vehicle and maintain it in prime
condition:

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine and
turning it off, wait more than 5 m inutes for the oil to drain back into
the bottom of the engine.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the fol-
lowing grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is expl ained here as an example):
• The 0W in 0W-20 indicates the ch aracteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the visc osity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity (one
with a higher value) may be better su ited if the vehicle is operated at
high speeds, or under extreme load conditions.
How to read oil container label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark is
added to some oil containers to
help you select the oil you should
use.
