matically.
■Manual operation
Even if the active rear wing is changed to
manual operation using the active rear wing
switch, the setting will not be maintained.
Automatic operation will resume if the
engine switch is turn ed off or at certain
vehicle speeds.
*: If equipped
Pressing the “TVD” switch changes the
TVD control mode.
The current TVD control mode will be dis-
played on the meters.
1 STANDARD mode
This is the default mo de and provides an
optimum balance of driving agility and sta-
bility.
WARNING
■When manually operating the active
rear wing
Observe the following precautions
before operating the active rear wing.
Failure to do so may result in death or
serious injury.
●Ensure that the surrounding area is
free of any objects that may come into
contact with or get caught on the
active rear wing.
●If there are people near the active rear
wing, make sure that there is no possi-
bility of their clothing, personal
belongings or body parts getting
caught. Children especially should be
warned not to touch the active rear
wing while it is being operated.
●If there is a risk that an object may
become caught on the active rear
wing during operation, stop operation
immediately.
NOTICE
■To prevent battery discharge
Do not operate the active rear wing
repeatedly while the engine is turned off.
TVD (Torque Vectoring Dif-
ferential)*
The TVD system distributes driving
force (torque) between the right
and left rear wheels automatically.
This system contributes to
enhanced steering response while
cornering and increased traction
when exiting a corner, providing an
agile driving experience.

3177-2. Steps to take in an emergency
7
When trouble arises
1Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen while
the vehicle is in motion, causing the tire to
come off.
2 Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum wheel with
an aluminum wheel, turn the wheel nuts
until the washers come into contact
with the disc wheel .
WARNING
■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 of f, 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 76 ft•lbf (103 N•m,
10.5 kgf•m) as soon as possible after
changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
• 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.
NOTICE
■Precaution for CCB (Carbon
Ceramic Brake) discs (if equipped)
Do not subject the carbon ceramic brake
disc to strong impact.
It the carbon ceramic brake disc has
been subjected to a strong impact, even
if there is no obvious damage, have the
vehicle inspected by your Lexus dealer.

3187-2. Steps to take in an emergency
3Lower the vehicle.
4 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)
5Stow the flat tire, tire jack and all
tools.
■The spare tire
●Use the spare tire temporarily, and only in
an emergency.
●Make sure to check the tire inflation pres-
sure of the spare tire. ( P.347)
■When using the spare tire
As the spare tire is not equipped with a tire
pressure warning valve and transmitter, low
inflation pressure of the spare tire will not be
indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after
the tire pressure warning light comes on,
the light remains on.
*:If equipped
■When the spare tire is equipped
The vehicle becomes lower when driving
with the spare tire compared to when driv-
ing with standard tires.
WARNING
■When using the spare tire
●Remember that the sp are tire provided
is specifically designed for use with
your vehicle. Do not use your spare
tire on another vehicle.
●Do not use more than one spare tire
simultaneously.
●Replace the spare tire with a standard
tire as soon as possible.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
■When the spare tire is attached
The vehicle speed may not be correctly
detected, and the following systems may
not operate correctly:
• ABS & Brake assist
•VSC
•TRAC
• Dynamic radar cruise control
•PCS
•EPS
• Adaptive Variable Suspension System
• LDA (Lane Departure Alert with steering control)
• VDIM (Vehicle Dynamics Integrated Management)
• Tire pressure warning system
• Lexus parking assist monitor
• Intuitive parking assist (if equipped)
• Navigation system (if equipped)
