to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
Before driving the vehicle

freezing.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
 Park the vehicle and move the shift
lever to P without setting the park-
ing brake. The parking brake may
freeze up, preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly lead-
ing to an accident.
When the parking brake is in automatic
mode, release the parking brake after shift-
ing the shift lever to P. ( P.172)
 If the vehicle is left parked with the brakes damp in cold temperatures,
there is a possibility of the brakes
freezing.
 If the vehicle is parked without set-
ting the parking brake, confirm that
the shift lever cannot be moved out
of P
*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position with out depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a problem
with the shift lock system. Have the vehi-
cle inspected by your Lexus dealer
immediately.
Use the correct tire chain size when
mounting the tire chains. Chain size is
regulated for each tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width

WARNING
■When parking the vehicle
When parking the vehicle without apply-
ing the parking brake, make sure to
chock the wheels. If you do not chock the
wheels, the vehicle may move unexpect-
edly, possibly result ing in an accident.

Driving
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 we t, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
 AWD models: Avoid driving on very
steep, slippery roads and other sur-
faces, such as sand, where the tires
are liable to lose traction. Your vehi-
cle may not perform as well as con-
ventional AWD on-road vehicles on
these surfaces.
■Additional informatio n 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
■Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death or 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.
●After driving through tall grass, mud,
rock, sand, water, et c., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear of f 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 safety measures to
ensure that water damage to the hybrid
battery (traction battery), hybrid system
or other components does not occur.
●Water entering the engine compart-
ment may cause seve re damage to the
hybrid system. Water entering the inte-
rior may cause the hybrid battery
stowed under the re ar seats to short
circuit.

2684-6. Driving tips
NOTICE
●Water entering the hybrid transmis-
sion and rear electric motor (traction
motor) will cause deterioration in
hybrid transmission quality. The mal-
function indicator may come on, and
the vehicle may not be drivable.
●Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and may also enter the
hybrid transmission 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”.
