Driving
■Driving mode select switch
The suspension can be switched for improvement in driveability. (P. 2 8 6 )
■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 ba ll 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 sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal i mmediately 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.
●After the trailer sw aying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.

■When starting the engine
Always start the engine while
sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.
■Stopping the engine in an emergency
●If you want to stop the engine in an emergency while driving the vehicle, press and
hold the engine switch for more than 2 seco nds, or press it briefly 3 times or more in
succession. ( P. 5 1 5 )
However, do not touch the engine switch while driving except in an emergency. Turn-
ing the engine off while driving will not cause loss of steering or braking control, but
the power assist to these systems will be lost . This will make it more difficult to steer
and brake, so you should pull over and stop th e vehicle as soon as it is safe to do so.
●If the engine switch is operated while the vehicle is running, a warning message will be
shown on the multi-information display and a buzzer sounds.
●When restarting the engine after it was turn ed off while driving, shift the shift lever to
N and press the engine switch.

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: If equipped, by selecting shift ranges us ing paddle shift switches, you can control
engine braking forces.
*3: Selecting shift ranges using S mode rest ricts the upper limit of the possible gear
ranges, controls engine braking forces , and prevents unnecessary upshifting.

■Paddle shift switches (if equipped)
●When the “-” paddle shift switch is operated
in the D position, a shift range will be auto-
matically selected. The highest gear of the fi rst shift range will be one gear lower than
the gear in use during normal D position driving.
●Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
• When the vehicle comes to a stop
• If the accelerator pedal is depressed for long er than a certain period of time in one
shift range
■Driving on a downhill
On declines, there may be case where the ve hicle shifts down automatically to obtain
engine braking. As a result of the down shifting, 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 7 or lower, holding the shift lever toward “+” sets the shift range to
8.
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance and
driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting the
shift lever to the S position cancels the function.)
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or radar cruise control will not be
canceled.
●While driving in D position (vehicles with paddle shift switches) or S mode, downshift-
ing to 7, 6, 5 or 4. ( P. 2 7 1 , 2 8 3 )
●When switching the driving mode to spor t mode while driving in D position. (P. 2 8 6 )
■If the shift lever cannot be shifted from P
P. 5 4 9
■If the “S” indicator does not come on ev en 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 operat e in the same manner as when the shift lever
is in D.)
■Downshift restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)

LX570_OM_OM60N01U_(U)4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main
tain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating th e vehicle-to-vehicle distance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). The system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. Approach wa rning warns you when the system cannot
decelerate sufficiently to prevent your ve hicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator peda l will resume follow-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.

Short
The vehicle-to-vehicle distance is set
automatically to long mode when the
engine switch is turned to IGNITION
ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 50 mph (8 0 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle- to-vehicle distance will be about 16 ft.
(5 m) to 23 ft. (7 m) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

■In the following cases the 4-Wheel AHC will not operate
●The brake pedal has been depressed for a few seconds or longer while the vehicle is
stopped.
●Vehicle height control has not been frequently used.
●The suspension fluid temperature is lower than -22°F (-30°C).
●There is ice on the suspension.
●Driving on bumpy roads which may cause
the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the center
differential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid temperature
drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C).
●In this case, even if the height select switch is pressed, th e vehicle height will not change.
Once the vehicle has been driven for a short time and the suspension fluid has been
warmed to within normal operating limits, the 4-Wheel AHC will begin operating and
the vehicle height will automatically change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not be able
to be raised, even if the 4-Wheel AHC is oper ating. In this case, pull the height select
switch to “ ” then push to “ ” after driving for a short time longer to select the desired
vehicle height.
■Parking and stopping tips
●If you immediately stop the engine after off-road driving, the vehicle height may gradu-
ally lower. When parking, make sure ther e is nothing under the vehicle that may come
in contact with the underbody. The vehicle will return to the set height when the engine
is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other than P
or N while the vehicle is stopped, you may hear a sound caused by the expansion and
contraction of the propeller shaft. Th is does not indicate a malfunction.
■4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC , normal mode is automatically selected.
However, the system may not switch to norm al mode depending on the location of the
malfunction.
The warning message is displayed on the mu lti-information display, and the 4-Wheel
AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the warning message turns off, the system is operat-
ing correctly. If the warning message continue s to be displayed, have the vehicle checked
at your Lexus dealer as soon as possible.
