When driving
GX460_U.S.A. (OM60J00U)
CAUTION
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems; if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance will increase.
If this happens, do not continue to drive the vehicle. Have your brakes fixed
immediately.
NOTICE
■While 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 pedals 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.

Tr a i l e r To n g u e We i g h t● 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
Tongue weight
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 connection.
The gross trailer weight, gross axle weight and tongue weight can be
measured with platform scales found at a highway weighing station,
building supply company, trucking company, junk yard, etc.

5-2. Steps to take in an emergency
GX460_U.S.A. (OM60J00U)Firmly tighten each nut two or
three times in the order shown in
the illustration.
Tightening torque:
83 ft•lbf (112 N•m, 11.4 kgf•m)
Reinstall the wheel ornament.
Stowing the flat/spare tire, jack and tools
Lay down the tire with the outer
side facing up, and install the hold-
ing bracket.
Insert the holding bracket tab into
one of the holes in the wheel.
Raise the tire.
Pull the tire towards the rear of the vehicle when raising. After

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.
• Lower the spare tire completely to the ground before removing it from underthe vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
• Have the wheel nuts tightened with a torque wrench to 83 ft•lbf (112 N•m, 11.4 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.
• When installing the wheel nuts, be sure to install them with the tapered ends facing inward. ( →P. 640)
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage
location to reduce the possibility of personal injury during a collision or sudden
braking.
