NOTICE
When driving the vehicle
Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
Do not use the accelerator pedal or depress the accelerator and brake ped-
als at the same time to hold the vehicle on a hill.
When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is
accidentally depressed.
Avoiding damage to vehicle parts
Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.

Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it
alerts the driver using beeping, screen displays and a sensory
warning
* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direc-
tion of the center of the lane.
Lane keeping assist function
• This function will be active when the vehicle-to-vehicle dis-
tance control mode of the cruise control (P. 302) is set with
vehicle speed above approximately 72 km/h (45 mph) and
while the lane departure warning function is active.
• When the lane keeping assist function is active, a slight steer-
ing torque will be applied, to help the driver maintain the vehi-
cle inside the lane.
The lane keeping assist function will be temporarily canceled if the
steering wheel is not operated, or if you continue driving with your
hands lightly touching the steering wheel. (P. 343)

Hybrid vehicle driving tips
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be min-
imized, improving the fuel economy. (P. 392)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 126)
When braking the vehicle
Make sure to operate the brakes gently 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 fuel consumption. Check traffic
reports before leaving 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 over-
use of the accelerator 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
For economical and ecological driving, pay attention to the follow-
ing points:

CAUTION
Replacing a flat tire
Do not touch the disc wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or
other body parts while changing a tire, etc. may result in burns.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N•m
(10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or
bolt holes of the wheel, have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
