Driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shift changing, or changes in engine
speed could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or roll
forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine from
the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident.
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.

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 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.
■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 pump.
●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 follo wing situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire. ( →P. 5 2 7 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

Driving
●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, and slow down before making a turn.
●Note that when making a turn, the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate by making a wider than normal
turning radius.
●Slow down before making a turn, in crosswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer.
●Take care when passing other vehicles. Passing requires considerable dis-
tance. After passing a vehicle, do not forget the length of your trailer, and be
sure you have plenty of room before changing lanes.
●To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 5 or lower.
●Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending steep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, your vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperature gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. (→ P. 5 4 8 )

GX 460 _O M_ OM6 0K 80 U_ (U)4-1. Before driving
●Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Apply the parking brake
firmly, and put the transmission in P.
Avoid parking on a slope, but if unavoidable, do so only after performing the
following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and trailer’s
wheels.
When the wheel blocks are in place, release the brakes slowly until the
blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
●When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the brake pedal
pressed.
Shift into 3, 2, L, or R (if reversing).
Release the parking brake and brake pedal, and slowly pull or back away
from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

■AVS (adaptive variable suspension system)
The suspension can be switched fo
r improvement in driveability. (→P. 331)
■Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differential or wheel bearing), Lexus recommends that you do not
tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately 600 miles
(1000 km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize.

GX 460 _O M_ OM6 0K 80 U_ (U)4-2. Driving procedures
Automatic transmission
While the engine switch is in IGNITION ON mode, move the shift lever
with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: Shifting to the D position allows the system
to select a gear suitable for the driving
conditions. Setting the shift lever to the D position is recommended for normal driv-
ing.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gear ranges, controls engine braking forces, and prevents unnecessary upshifting.

Driving
■Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically to obtain
engine braking. As a result of the downshifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shif t lever is in the D position. (Shifting the
shift lever to the S position cancels the function.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( → P. 2 1 4 , 2 1 7 )
■If the shift lever cannot be shifted from P
→P. 5 4 2
■If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift lever
is in D.)
■Downshift restriction warning buzzer (S mode)
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downsh ifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause th e vehicle to spin or skid, resulting in an
accident.
