●A recommended tongue weight varies in accordance with the types of trailers
or towing as described below.
●To ensure the recommended values shown below, the trailer must be loaded
by referring to the following instructions.•Tongue Weight
The gross trailer weight should be distributed so that the tongue weight is
9 % to 11 %. (Tongue weight/Gross trailer weight × 100 = 9 % to 11 %)
Gross trailer weight
To n g u e w e i g h t
If using a weight distributing hitch when towing, return the front axle to the
same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the front fender
height above the front axle before connection. Adjust weight distributing
hitch torque until front fender is returned to the same height as before con-
nection.
The gross trailer weight, gross axle weight and tongue weight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

◆Active TRAC (Traction Control) for L4 position*
Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippery roads, or in off-road conditions
◆Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backwa
rd when starting on an incline or slip-
pery slope
◆KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and handling response by using a hydraulic con-
trol system to control the suspension stabiliz er bars in response to road surface and
driving conditions during co rnering or off-road driving
◆PCS (Pre-Collision system) (if equipped)
→P. 3 6 8
◆Tr a i l e r S w a y C o n t r o l
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine torque when trailer sway is detected.
Trailer Sway Control is part of the VSC sy stem and will not operate if VSC turned off
or experiences a malfunction.
*: The function only works in vehicles with Multi-terrain Select when Multi-terrain
Select is switched on
If the vehicle is in danger of slipping or
rolling backward when starting on an
incline, or if any of the drive wheels
spins, the slip indicator light flashes to
indicate that the TRAC or Active
TRAC/VSC/Trailer Sway Control/hill-
start assist control systems are operat-
ing.
The stop lights and high mounted stoplight turn on when the hill-start assist control
system is operating.

When trouble arises
CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from under the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
• 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 nuts to loosen and the wheel may
fall off, which could lead to an accid ent causing 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.
