NOTICE
nWhen encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
lEngine stalling
lShort in electrical components
lEngine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
lBrake function
lChanges in quantity and quality of oil and fluid used for the engine, transaxle,
transfer (AWD models), differential, etc.
lLubricant condition for the propeller shaft (AWD models), bearings and suspen-
sion joints (where possible) and the function of all joints, bearings, etc.

When driving
CAUTION
nOff-road driving precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle:
lDrive carefully when off the road. Do not take unnecessary risks by driving in
dangerous places.
lDo not grip the steering wheel spokes when driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim.
lAlways check your brakes for effectiveness immediately after driving in sand,
mud, water or snow.
lAfter driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could occur.
lWhen driving off-road or in rugged terrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.
NOTICE
nTo prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
lWater entering the engine air intake will cause severe engine damage.
lWater entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
lWater can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.

266
2-5. Driving information
lWhen restarting after parking on a slope:
With the transmission in the P position, start the engine. Be sure
to keep the brake pedal depressed.
Shift into 3, 2, 1, or the R position (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
nBefore towing
Check that the following conditions are met:
lThe vehicle's tires are properly inflated. (→P. 4 8 7 )
lTrailer tires are inflated according to the trailer manufacturer's recommendation.
lAll trailer lights work.
lAll lights work each time you connect them.
lThe trailer ball is set up at the proper height for the coupler on the trailer.
lThe 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.
lThe trailer cargo is securely loaded.
lThe rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.
nBreak-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential and wheel bearing), Lexus recommends that
you do not tow a trailer until it has been driven for over 500 miles (800 km).
However, avoid full throttle acceleration.
nMaintenance
lIf you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual Sup-
plement” or “Scheduled Maintenance”.)
lRetighten the fixing bolts of the towing ball and bracket after approximately 600
miles (1000 km) of trailer towing.
