2-5. Driving information
■Before towing
●Ensure that your vehicle’s tires are properly inflated. (P.283 )
●Trailer tires should be inflated according to the trailer manufacturer’s recom -
mendation.
●All trailer lights must work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, instal l rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
p

ower train components (engine, transmissi on, differential, wheel bearing, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (see “Owner’s Manual Supplement/ Scheduled Mainte -
nance”)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface, which
can harm your vehicle’s paint.
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows or door weather seals of your vehicle.
Before entering the automatic car wash, check that the fuel filler door on your vehi -
cle is closed properly.
Follow these guidelines when washing and waxing your Lexus:
●Working from top to bottom, libera lly apply water to the vehicle body,
wheel wells and underside of the vehi cle to remove any built up dirt
and dust. 
Wash the vehicle body using a sponge or sof
t cloth, such as a chamois.
●For hard-to-remove dirts, use car wash soap and rinse thoroughly with
water.
●Thoroughly dry your vehicle.
●Apply polish or wax only when the vehicle body is cool. 
Wax or polish your vehicle when the e
xisting coating of wax or polish
begin to deteriorate. A good way to determine this, is by checking to
see if water beads on the painted surfac e of your vehicle. If it does not
bead, that means the wax or polish is no longer protecting the finish,
and therefore should be reapplied.

●Wash the car immediately in the following cases:
• After driving near the sea coast.
• After driving on salted roads.
• If you see coal tar or tree sap on the paint surface
• If you see dead insects or in sect dr
oppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust, iron po
wder or chemical substances.
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately

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 point.
■Plastic bumpers and side moldings

■Windshield and front door glass water-repellent coating
The following precautions can extend the e
ffectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the windshield 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 cont
ain abrasires when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.

Maintenance and care
Cleaning and protecting the vehicle interior
The following procedures will help protect your vehicle’s interior and keep it
in top condition.
■Protecting the vehicle interior
Remove dirt and dust using a vacu um cleaner and wipe dir
ty surfaces
with a cloth dampened with lukewarm water.
■ Cleaning the leather seats
• Remove dirt and dust using a vacuum cleaner.
• Wipe any excess dirt and dust wi th a sof
t cloth dampened with
diluted detergent. 
Use a diluted water soluti on of appr
oximately 5% neutral detergent
for wool.
• Wring out any excess water from the cloth and thoroughly wipe off all r
emaining traces of detergent.
• Wipe the surface with a dry, soft cloth to r
emove any remaining
moisture. Allow the leather to dry in a ventilated and shaded area.
■ S
ynthetic leather areas
First vacuum over the upholstery to r
emove loose dirt. Then, using a
sponge or soft cloth, apply a mild so ap solution to the synthetic leather. 
After allowing it to soak in for a few minutes to loosen the dir
t, remove
the dirt and wipe off the soap with a clean damp cloth.

248
4-1. Maintenance and care
■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
r
ear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the window in strokes running parallel to the
heater wires.
■Caring for leather seats
Lexus recommends regularly cleaning the interior of the vehicle at least twice a
y
ear to maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available.
Use a sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
w
ater. The best results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
Be careful not to splash water or spill liquid on the floor.
Do not get any of the safety system and co ntr
ol units, such as SRS airbags, in the
vehicle interior wet. 
Electrical malfunction may cause the airbag s to deplo
y or not function properly,
resulting in death or serious injury.
