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 wher e 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 road s. When conditions are wet, driving techniques
should be changed or travel dela yed 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

WARNING
■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 effectiveness 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 underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain , do not drive at excessive speeds, jump,
make sharp turns, strike obje cts, 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 quality. 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 transmissi on case, reducing the gear oil’s lubricat-
ing 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 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 Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.
