NX300h_U_OM78007U In steering control, the steering control
indicator will come on. ■
If “Lane Departure Alert Malfunction Visit Yo ur Dealer” is displaye d on the multi-infor-
mation display
Even if the LDA switch is pressed, when th e LDA indicator does not come on the system
may have a malfunction. Have the vehicle in spected by your Lexus dealer immediately.■
The steering control function
There are cases where it may be difficult to sense the steering force on the steering
wheel by the steering control, according to speed, the deviatio n situation, conditions of a
road, etc. ■
Alert buzzer for lane deviation alert
Depending on the audio system sound level or air conditioning fan noise while the audio
system or air conditioning system is in use, it may be difficult to hear the alert buzzer.■
After the vehicle has been parked in the sun
The LDA may not be available and a warning message will be displayed for a while after
driving has started. When the temperature in the cabin decreases and the temperature
around the lane recognition camera (  P. 270) becomes suitable for its operation, turn
the LDA switch on again after a short time. ■
If there are lane markers on only one side of the vehicle
The lane deviation alert will not operate for the side on which lane markers could not be
recognized. ■
Conditions in which the functi on may not operate correctly
In the following situations, the lane recognition camera may be unable to recognize lane
markers causing the lane deviation alert function to operate incorrectly. However, this
does not indicate a malfunction. ●
When there are shadows on the road running parallel with lane mark ers, or if a shadow
covers the lane markers ●
When driving through an area with no lane markers, such as a toll booth, a crossing or
before a ticket checkpoint ●
When the lane markers are broken, Botts’ dots (raised pavement markers) or stones ●
When lane markers are obscured or partially obscured by sand, dirt, etc. ●
When driving on a road surface that is wet du e to rain, previous rainfall, standing water,
etc. ●
When the lane markers are yellow (These may be more difficult for the system to rec-
ognize compared to white markers.)Display while in steering control

The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle ●
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obst acle detection and display. Even at slow
speeds, there is a possibility that the obstacle w ill come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sensor may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.■
If “Clean Parking Assist Sensor” is di splayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from the
sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may not be detected. If the sensor thaws out, the system should
return to normal. ■
If “Parking Assist Malfunction” is di splayed on the multi-information display
Depending on the malfunction of the sensor, the device may not be working normally.
Have the vehicle inspected by your Lexus dealer. ■

Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air condi-
tioning system to enhance fuel efficiency. To improve air conditioning performance,
adjust the fan speed or turn off Eco drive mode. ■
Sport mode automatic deactivation
Sport mode is automatically deactivated if th e power switch is turned off after driving in
sport mode.

324 4-6. Driving tips
NX300h_U_OM78007UHybrid vehicle 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 0 3 )
◆ Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle 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.For economical and ecological driving, pay attention to the following points:

Driving
NX300h_U_OM78007U ◆ Delays
Repeated acceleration and deceleration, 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 drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆ Highway driving
Control and maintain the vehicle at a co nstant 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.
◆ Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce th e burden on the air conditioning system
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 con-
sumption can be improved by avoiding overuse of the heater.
◆ Checking tire inflation pressure
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 amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆ Warming up before driving
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 repeated ly warm up, which can lead to excess
fuel consumption.
