LX570_OM_OM60Q78U_(U) 6-1. Maintenance and care
Cleaning and protect ing the vehicle exterior●
Working from top to bott om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e 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 wa sh soap and rins e 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.■
Automatic car washes ●
Fold the mirrors back before washing the ve hicle. 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 wash able 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 prop-
erly. ■
Wheels (including surrounding parts) ●
Remove any dirt immediately by using a neut ral 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.Perform the following to protect the ve hicle and maintain it in prime condi-
tion:

Maintenance and care ■
Tire inflation pressure check interval
You should check tire inflation pressure ever y two weeks, or at least once a month. Do
not forget to check the spare. ■
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:●
Reduced fuel economy ●
Reduced driving comfort and poor handling ●
Reduced tire life due to wear ●
Reduced safety ●
Damage to the drive train
If a tire needs frequent inflating, ha ve it checked by your Lexus dealer.■
Instructions for checking tire inflation pressure
When checking tire in flation pressure, ob serve the following:●
Check only when the tires are cold.
If your vehicle has been parked for at le ast 3 hours and has not been driven for more
than 1 mile or 1.5 km, you will get an accu rate cold tire inflat ion pressure reading.●
Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appearance. ●
It is normal for the tire inflat ion pressure to be higher after driving as heat is generated
in the tire. Do not reduce tire inflation pressure after driving.●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.

When trouble arises WARNING ■
Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recomm ended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label (tire and load information label). (If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire
inflation pressure label [tire and load in formation label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle ha s been equipped with a tire pressure moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when on e or more of your tires is significantly
under-inflated. Accordingly, when the low ti re pressure telltale (tire pressure warning
light) illuminates, you should st op and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a si gnificantly under-inflat ed tire causes the
tire to overheat and can lead to tire failure . Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure wa rning system) is not a substitute for proper
tire maintenance, and it is th e driver’s responsibility to ma intain correct tire pressure,
even if under-inflation has not reached the le vel to trigger illumina tion of the TPMS low
tire pressure telltale (tir e pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS
(tire pressure warning system) malfunction indi cator is combined with the low tire pres-
sure telltale (tire pressure warning light). When the system detects a malfunction, the
telltale will flash for approximately one mi nute and then remain continuously illumi-
nated. This sequence will cont inue upon subsequent vehicl e start-ups as long as the
malfunction exists. When the malfunction in dicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfun ctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning system) malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressu re warning system) to continue to function
properly.
NOTICE ■
To ensure the tire pressure warning system operates properly
Do not install tires with different specificatio ns or makers, as the tire pressure warning
system may not operate properly.
