2744-6. Driving tips
Your vehicle is not designed to be
driven off-road. However, in the event
that off-road driving cannot be
avoided, please observe the following
precautions to help avoid the areas
prohibited to vehicles.
Drive your vehicle only in areas
where off-road vehicles are permit-
ted to travel. 
Respect private property. Get
owner’s permission before entering
private property.
 Do not enter areas that are closed.
Honor gates, barriers and signs that
restrict travel.
 Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
■Additional information for off-road driv-
ing
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the
following organizations.
●State and Local Parks and Recreation
Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of Land
Management
WARNING
●In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Therefore,
the driver and all passengers should
always fasten th eir seat belts.
●Avoid sharp turns or abrupt maneu-
vers, if at all possible.
Failure to operate this vehicle correctly
may result in loss of control or vehicle
rollover causing death or serious
injury.
●Loading cargo on the roof luggage
carrier will make the center of the
vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers,
otherwise it may result in loss of con-
trol or vehicle rollover due to failure to
operate this vehicle correctly.
●Always slow down in gusty crosswinds.
Because of its profile and higher cen-
ter of gravity, your vehicle is more sen-
sitive to side winds than an ordinary
passenger car. Slowing down will allow
you to have better control.
●Do not drive horizontally across steep
slopes. Driving straig ht up or straight
down is preferred. Your vehicle (or any
similar off-road vehicle) can tip over
sideways much more easily than for-
ward or backward.
Off-road driving
WARNING
■Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death, seri-
ous injury or damage to your vehicle:
●Drive carefully when off the road. Do
not take unnecessary risks by driving in
dangerous places.
●Do 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.
●Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.

Driving
WARNING
●After driving through tall grass, mud,
rock, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped on 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 break-
down or fire could occur.
●When 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 vehicle rollover causing
death or serious injury. You are also
risking expensive damage to your
vehicle’s suspension and chassis.
NOTICE
■To prevent water damage
Take all necessary sa fety measures to
ensure that water da mage to the engine
or other components does not occur.
●Water entering the engine air intake
will cause severe engine damage.
●Water entering the automatic trans-
mission will cause deterioration in shift
quality, locking up of your transmission
accompanied by vibr ation, and ulti-
mately damage.
●Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and ma y also enter the dif-
ferential, transmission and transfer
(AWD models only) case, reducing
the gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when
crossing shallow stre ams, 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
around brake discs may affect braking
efficiency and may damage brake sys-
tem components.
●Always perform a maintenance
inspection after 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 Services
Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.

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 water-
proof 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 coat-
ing 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 tem-
perature.
The restoration ti me may become
shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins,
etc. cannot be restored.
●Do not use wax that contains abrasives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door

●Rear spoiler may not be washable in
some automatic car washes. There may
also be an increased risk of damage to
vehicle.
■High pressure car washes
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■When using a car wash
If the door handle becomes wet while the
electronic key is within the effective range,
the door may lock and unlock repeatedly. In
that case, follow the following correction
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the

3586-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on
a tire.
●You have tire damage such as cuts, splits,
cracks deep enough to expose the fabric,
and bulges indicating internal damage.
●A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca-
tion of a cut or other damage.
If you are not sure, consult with your Lexus
dealer.
■Tire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
■Proper storage of the spare tire
(RX350L)
As an improperly stored spare tire may
cause damage to the wi re cable that holds
it, check that the spare tire is stored prop-
erly on a daily basis.
●If the stored spare tire appears to be
slanted or rattles while driving, the spare
tire may not be properly stored. Store the
spare tire again by performing the follow-
ing tire change procedure correctly:
1 If the spare tire is slanted, the hoist
assembly may be stuck in the wheel
opening. If the spare tire rattles while
driving, it may not be fully raised. Lower
the spare tire to the ground and make
sure that the hoist assembly is perpen-
dicular to the wheel opening.
2 Raise the tire slowly and steadily until a
click is heard and th e jack handle skips.
If the spare tire cannot be lowered, the wire
cable may be severed. Have the vehicle inspected at your Lexus dealer.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. ( P.440)
■Tire types
●Summer tires
Summer tires are high-speed performance
tires best suited to highway driving under
dry conditions. Since summer tires do not
have the same traction performance as
snow tires, summer ti res are inadequate for
driving on snow-covered or icy roads. For
driving on snow-cov ered roads or icy
roads, the use of snow tires is recom-
mended. When installing snow tires, be
sure to replace all four tires.
●All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions as well
as for use year-round. All season tires,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in accelerati on and handling per-
formance compared with summer tires in
highway driving.
●Snow tires
For driving on snow-covered roads or icy
