Before driving
Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■ Using Eco Mode
When using Eco mode, the torque corresponding to the accelerator pedal
depression amount can be generated more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system will be
minimized, improving the fuel economy.
( P. 1 5 5 )
■Use of Hybrid System Indicator
The environmentally-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. ( P. 1 6 4 )
■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 fuel consumpt ion. Check traffic reports before leav -
ing and avoid delays as much as possible. When encountering a delay,
gentl
y 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.

When driving
■Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco mode
Suitable for improving the fuel
economy, because the torque
corresponding to the accelera-
tor pedal depression amount
can be gener
ated more
smoothly than it is in normal
conditions and the operation of
the air conditioning system will
be minimized.
When the Eco mode switch is
pr
essed, the “ECO MODE”
indicator comes on in the meter.
Power mode
Suitable when the vehicle needs
to drive powerfully or travels in
mountainous areas.
When the power mode switch is
pr
essed, the “PWR MODE”
indicator comes on in the meter.

When driving
LKA (Lane-Keeping Assist)
: If equipped
While driving on a freeway or motor highway that has lane markers, this
system recognizes the lanes using a camera as a sensor to assist the driver
with staying in the lane. The LKA system has two functions.
■Lane departure warning function
If the system judges that the vehicl e may deviate from its lane, it
alerts the driver using rapid beepin g, indications on the multi-infor-
mation display, and a sensory warning
* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the
direction of the center of the lane.
■ Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance
control mode of the cruise control ( P. 205) is set with vehicle
speed above approx. 45 mph (approx . 72 km/h) and while the lane
departure warning function is acti ve. When the lane keeping assist
function is active, a slight steering torque will be applied, to help the
driver maintain the vehicle inside the lane.

5-2. Steps to take in an emergency
Firmly tighten each wheel nut two
or three times in the order shown
in the illustration.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools.
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflatio n pressure of the compact spare tire.
( P. 555 )
■After completing the tire change
The tire pressure warning system must be reset. ( P.
4 3 9 )
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve and
tr
ansmitter, low inflation pressure of the spare tire will not be indicated by the tire
pressure warning system. Also, if you repl ace the compact spare tire after the tire
pressure warning light comes on, the light remains on.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the
fo
llowing steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi -
cle.
Fit tire chains to the front tires.

When trouble arises

5-2. Steps to take in an emergency
CAUTION
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
●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 your Lexus dealer.
Failure to follow these precautions could cause the wheel nuts to loosen and the tire
to fall off, resulting in death or serious injury.
NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel
beyond repair.
■Be careful when driving over bumps with the compact spare tire installed on the
vehicle.
The vehicle becomes lower when driving with the compact spare tire compared to
when driving with standard tires. Be careful when driving over uneven road sur-
faces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving performance.
■When replacing the tires
When removing or fitting the wheels, tire s or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and trans-
mitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmitters
Do not use liquid sealants on flat tires.
