LX570_OM_OM60Q78U_(U) 4-6. Driving tips
NOTICE ■
To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or other
components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompan ied by vibration, and ultimately damage.●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differentials, tr ansmission and transfer case, reducing the
gear oil’s lubricating qualities. ■
When you drive through water
If driving through water, such as when cro ssing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection afte r each day of off-road driving that has
taken you through rough terrain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Se rvices Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

LX570_OM_OM60Q78U_(U) 6-1. Maintenance and care
NOTICE ■
To prevent paint deterioration and corrosion on the body and components (aluminum
wheels etc.) ●
Wash the vehicle immediatel y in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If you see dead insects, insect drop pings or bird droppings on the paint
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoli ne are spilled on the paint surface●
If the paint is chipped or scratched, have it repaired immediately. ●
To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing wheels. ■
Cleaning the exterior lights ●
Wash carefully. Do not use organic subs tances or scrub with a hard brush.
This may damage the surfaces of the lights.●
Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses. ■
When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper blades may be
damaged. ■
When using a high pressure car wash
Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts

Maintenance and care Check the radiator and condenser and clear any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their condi-
tion, have your vehicle checked by your Lexus dealer.
■
Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank. NOTICE ■
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water and
antifreeze must be used to provide proper lubrication, corrosion protection and cool-
ing. Be sure to read the antifreeze or coolant label.■
If you spill coolant
Be sure to wash it off with water to pr event it from damage to parts or paint.
Radiator and condenser WARNING ■
When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause serious injuries,
such as burns.

Adding fluid
Make sure to check the fluid type and prepare the necessary item. ■
Refilling brake fluid
Turn the engine switch off.
Depress the brake pedal more than 40 times.
Remove the reservoir cap by hand. Ad d brake fluid up to the “MAX” line.If you do not follow the procedure above, the reservoir may overflow.■
Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dang erous loss of braking efficiency. Use only
newly opened brake fluid. Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
WARNING ■
When filling the reservoir
Take care because brake fluid can harm yo ur hands or eyes and damage painted sur-
faces. If fluid gets on your eyes, flush the affected area with clean water immediately. If
you still experience discomfort, see a doctor.
NOTICE ■
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs freq uent refilling, it may
indicate a serious problem. 1

514 7-2. Steps to take in an emergency
LX570_OM_OM60Q78U_(U) If your vehicle is transported by a flat-
bed truck, it should be tied down at the
locations shown in the illustration.
If you use chains or cables to tie down
your vehicle, the angles shaded in black
must be 45 ° .
Do not overly tighten the tie downs or
the vehicle may be damaged.
If a tow truck is not available in an em ergency, your vehicle may be temporarily
towed using cables or chains secured to the emergency towing hooks. This
should only be attempted on hard su rfaced roads for at most 50 miles (80 km)
at under 18 mph (30 km/h).
A driver must be in the vehicle to st eer and operate the brakes. The vehicle’s
wheels, drive train, axles, steering an d brakes must be in good condition.Using a flatbed truck
