when

●

The limits of tire gripping performance

have been exceeded (such as exces-

sively worn tires on a snow covered

road).

●

The vehicle hydroplanes while driving

at high speed on wet or slick roads.

■

Stopping distance when the ABS is

operating may exceed that of normal

conditions

The ABS is not designed to shorten the

vehicle’s stopping distance. Always main-

tain a safe distance from the vehicle in

front of you, especially in the following

situations:

●

When driving on dirt, gravel or

snow-covered roads

●

When driving with tire chains

●

When driving over bumps in the road

●

When driving over roads with potholes

or uneven surfaces

■

TRAC/VSC may not operate effec-

tively when

be achievable while driving on slippery

road surfaces, even if the TRAC/VSC

system is operating. Drive the vehicle

carefully in conditions where stability and

power may be lost.

■

Hill-start assist control does not oper-

ate effectively when

●

Do not overly rely on hill-start assist

control. Hill-start assist control may

not operate effectively on steep

inclines and roads covered with ice.

●

Unlike the parking brake, hill-start

assist control is not intended to hold

the vehicle stationary for an extended

period of time. Do not attempt to use

hill-start assist control to hold the vehi-

cle on an incline, as doing so may lead

to an accident.

■

WARNING

■

When the TRAC/VSC systems are

turned off

Be especially careful and drive at a speed

appropriate to the road conditions. As

these are the systems to help ensure

vehicle stability and driving force, do not

turn the TRAC/VSC systems off unless

necessary.

■

Secondary Collision Brake

Do not overly rely on the Secondary Col-

lision Brake. This system is designed to

help reduce the possibility of further

damage due to a secondary collision,

however, that effect changes according

to various conditions. Overly relying on

the system may result in death or serious

injury.

■

Replacing tires

Make sure that all tires are of the speci-

fied size, brand, tread pattern and total

load capacity. In addition, make sure that

the tires are inflated to the recom-

mended tire inflation pressure level.
The ABS, TRAC and VSC systems will

not function correctly if different tires are

installed on the vehicle.

Contact your Lexus dealer for further

information when replacing tires or

wheels.

■

Handling of tires and the suspension

Using tires with any kind of problem or

modifying the suspension will affect the

driving assist systems, and may cause a

system to malfunction.

Driving

4-6.Driving tips

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.
(

P.297)

The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. (

P.82, 87)

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. In the N position, the
gasoline engine operates but electric-
ity 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.

Hybrid vehicle driving tips

For economical and ecological
driving, pay attention to the follow-
ing points:

Using Eco drive mode

Use of Hybrid System Indicator

Changing the shift position

Accelerator pedal/brake pedal
operation

When braking

Delays

308

4-6. Driving tips

LS500h_OM_(U)_1809

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.

 Use fluids that are appropriate to

the prevailing outside temperatures.

• Engine oil
• Engine/power control unit coolant
• Washer fluid

 Have a service technician inspect

the condition of the 12-volt battery.

 Have the vehicle fitted with four

snow tires or purchase a set of tire
chains for the rear tires.

Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.

: Tire chains cannot be mounted on vehi-

cles with front and rear tires of differing
sizes.

Winter driving tips

Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.

Perform the following according to the
driving conditions:
 Do not try to forcibly open a window

or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
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 shift the shift posi-
tion to P without setting the parking
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 leading to
an accident.



Vehicles with front and rear tires of
the same size

Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
