ous injury.

●

Firmly grip the steering wheel. Steer

straight ahead. Do not try to control

trailer sway by turning the steering

wheel.

●

Begin releasing the accelerator pedal

immediately but very gradually to

reduce speed.

Do not increase speed. Do not apply

vehicle brakes.

If you make no extreme correction with

the steering or brakes, your vehicle and

trailer should stabilize. (

When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.

Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic, etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption.
RX350h: In the N position, the gaso-
line engine operates but electricity
cannot be generated. Also, when using
the air conditioning system, etc., the
hybrid battery (traction battery) power
is consumed.



Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.



Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.

Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.

Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

4-6. Driving tips

Driving

Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.

Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.

Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season.

Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.

Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

■

Utility vehicle precautions

Always observe the following precau-

tions to minimize the risk of death, seri-

ous injury or damage to your vehicle:

●

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 their 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 (if equipped) will make the cen-

ter 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 cor-

rectly.

●

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 straight 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.

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.

●

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.
