Before driving Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following
points:
■ Use of Hybrid System Indicator More Eco-friendly driving is possib le by keeping the indicate of Hybrid
System Indicator within Eco area.
■ When braking the vehicle Make sure to operate the brakes ge ntly and in good time. A greater
amount of electrical energy can be retained when slowing down.
■ Delays Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fu el consumption. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelerato r pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving Control your speed and keep at a constant speed. Also, 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
retained when slowing down.
■ Air conditioning Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing so
will help to reduce the burden on the air conditioning and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.

Before driving CAUTION●
In the following situations, the power b ack door may detect an abnormality and
automatic operation may be stopped. In this case, the back door has to be oper-
ated manually. Take extra care when on an incline, as the back door may open or
close abruptly.
• When the back door contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the
“POWER” switch is turned to ON mode or the hybrid system is started dur-
ing automatic operation●
If a bicycle carrier or similar heavy object is attached to the back door, the power
back door may not operate, causing itself to malfunction, or the back door may
suddenly shut again after being opened, causing someone’s hands, head or neck
to be caught and injured. When installing an accessory part to the back door,
using a genuine Lexus part is recommended.■
Jam protection function
Observe the following precautions.
Failure to do so may cause death or serious injury. ●
Be careful while the jam protection function is operating. Being hit by the back
door may result in an injury.●
Although the back door stops closing wh en the jam protection function detects
an object, take extra care as you may still be injured if part of your body is already
caught.●
If anything obstructs the power back door while it is closing, the jam protection
function will cause the back door to automatically operate in the opposite direc-
tion. However, be careful not to jam body parts in the doorframe, as an injury may
result.●
Never use any part of your body to intent ionally activate the jam protection func-
tion.
●
The jam protection function may not work if something gets caught just before
the back door fully closes. Be careful not to catch fingers or anything else.
