In this event, the steering wheel may move from its straight forward position, but it will
return when the system restarts.
●When the steering wheel is operated for
an extended period of time while the vehicle is stopped or is moving very slowly (on vehicles with LDH, DRS is dis-
abled together with VGRS)
●When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How- ever, the position will return to normal after VGRS is reactivated.
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its
straight forward position, but this will be corrected automatically when driving.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start
assist control and VGRS systems

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.242)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.86)
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.

4-6. Driving tips
Driving
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
•Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
 Tire chains can only be installed on
the rear tires. However, tire chains
cannot be installed on 275/35RF21
or 275/40RF20 rear tires.
Before installing tire ch ains, change all four
tires and wheels to those of the specified
size for use with tire chains (front tires:
245/45RF20, rear tires: 245/45RF20,
wheels: 20 x 8 1/2 J 25 inset). Use the
specified type of tire chains and install
them on the rear tires only.
For details, contact any authorized Lexus
retailer or Lexus authorized repairer, or
any reliable repairer.
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.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri- ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the
speed limit or the speed limit specified for the snow tires being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used, or 50 km/h (30 mph), which-
ever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
●Do not use LKA (Lane-Keeping Assist) system. (if equipped)
