RX450h_U_OM0E013U 4-6. Driving tips
◆ Using Eco drive mode
When using Eco drive mode, the torq ue corresponding to the accelerator
pedal depression amount can be generate d more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heat-
ing/cooling) will be minimized, improving the fuel economy. (  P. 3 7 7 )
◆ Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle (except F
SPORT models) or bar display (F SPOR T models) of Hybrid System Indicator
within Eco area. (  P. 100)
◆ Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in heavy traf-
fic, etc. Shift the shift lever to P when parking. When using the N, there is no
positive effect on fuel consumption. In the N, the gasoline engine operates but
electricity cannot be generated. Also, wh en using the air conditioning system,
etc., the hybrid battery (traction battery) power is consumed.
◆ Accelerator pedal/brake pedal operation ●
Drive your vehicle smoothly. Avoid ab rupt acceleration and deceleration.
Gradual acceleration and deceleration will make more effective use of the
electric motor (traction motor) wi thout having to use gasoline engine
power. ●
Avoid repeated acceleration. Repeated acceleration consumes hybrid bat-
tery (traction battery) power, resulting in poor fuel consumption. Battery
power can be restored by driving with the accelerator pedal slightly
released.
◆ When braking
Make sure to operate the brakes gently and in a timely manner. A greater
amount of electrical energy can be regenerated when slowing down.Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following points:

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 
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional informat ion 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 ManagementOff-road driving

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”.

Screen display during low temperatures
When the ambient temperature is extremely low, screen response may be delayed even
if the Remote Touch is operated.
WA R N I N G ■
When using the Remote Touch ●
Do not allow fingers, fingernails or hair to become caught in the Remote Touch as this
may cause an injury. ●

become very hot or cold due to the temperature inside the vehicle.
NOTICE ■
To prevent damage to the Remote Touch ●
Do not allow the Remote Touch to come into contact with food, liquid, stickers or lit
cigarettes as doing so may cause it to change color, emit a strange odor or stop func-
tioning. ●
Do not subject the Remote Touch to excessive pressure or strong impact as the knob
may bend or break off. ●
Do not allow coins, contact lenses or other such items to become caught in the
Remote Touch as this may cause it to stop functioning. ●
Items of clothing may rip if they beco me caught on the Remote Touch knob.●
