Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feat ure causes this type of vehicle to be
more likely to rollover. And, utility vehicles have a significantly higher rollover
rate than other types of vehicles. ●
An advantage of the higher ground clearance is a better view of the road
allowing you to anticipate problems. ●
It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.Utility vehicle precautions This vehicle belongs to the utility vehicl e class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity.

Utility vehicle precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle: ●
In a rollover crash, an unbelted person is si gnificantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten
their seat belts. ●
Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may re sult in loss of control or vehicle rollover
causing death or serious injury. ●
Loading cargo on the roof luggage carrier w ill 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 control or vehicle rollover due to failure
to operate this vehicle correctly. ●
Always slow down in gusty crosswinds. Be cause of its profile and higher center of
gravity, your vehicle is more sensitive 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 straight up or straight down is
preferred. Your vehicle (or any similar off-road vehicle) can tip over sideways much
more easily than forward or backward.

Driving
RX450h_U_OM0E013U 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 permitted 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 co nditions are wet, driving techniques
should be changed or travel delayed to prevent damage to roads. ●
AWD models: Avoid driving on very steep, slippery roads and other surfaces,
such as sand, where the tires are liable to lose traction. Your vehicle may not
perform as well as conventional AWD on-road vehicles on these surfaces.■
Additional information for off-road driving 

To obtain additional informat ion pertaining to driving your vehicle off-road, consult the
following organizations. ●

Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle: ●
Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous 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 effectivenes s immediately after driving in sand, mud,
water or snow. ●
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 materi-
als trapped or adhering to the underb ody, a breakdown or fire could occur.●
When driving off-road or in rugged terrai n, 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 vehi-
cle’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 compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery (traction battery)
stowed under the rear seats to short circuit. ●
Water entering the hybrid transmission and rear electric motor (traction motor)
(AWD models only) will cause deterioration in transmission qua lity. The malfunction
indicator may come on, and the vehicle may not be drivable. ●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the hybrid transmission case, reducing the gear oil’s lubricat-
ing qualities. ■
When you drive through water
If driving through water, such as when crossing 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 around brake discs may affect braking efficiency
and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.
