could result in death or serious injury.
Have the vehicle inspected by your
Lexus dealer immediately if this occurs.

Driving
Control can also help to stabilize the vehicle
and trailer.)
●After the trailer swaying 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 appropri-
ate, 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 pre-
vent instability. Remember that swaying of
the towing vehicle-trailer increases as
speed increases.
WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care
and drive the vehicle in accordance with
the trailer’s characteristics and operating
conditions. Failure to do so could cause
an accident resulting in death or serious
injury. Vehicle stabi lity and braking per-
formance are affected by trailer stability,
brake setting and performance, and the
hitch. Your vehicle will handle differently
when towing a trailer.
■To avoid accident or injury
●Do not exceed the TWR, unbraked
TWR, GCWR, GVWR or GAWR.
●If the gross trailer weight is over 2000
lb. (907 kg), a sway control device with
sufficient capacity is required.
●Adjust the tongue weight within the
appropriate range. Place heavier loads
as close to the trailer axle as possible.
●Do not exceed 65 mph (104 km/h),
the posted towing speed limit or the
speed limit for your trailer as set forth
in your trailer owner’s manual, which-
ever is lowest. Slow down sufficiently
before making a turn, in cross winds,
on wet or slippery surface, etc. to help
avoid an accident. If you experience a
vehicle-trailer instability from reduc-
ing a certain speed, slow down and
make sure you keep your vehicle
speed under the speed of which you
experience the instability.
●Do not make jerky, abrupt or sharp
turns.
●Do not apply the brakes suddenly as
you may skid, resulting in jackknifing
and loss of vehicle control. This is
especially true on wet or slippery sur-
faces.
●Do not exceed the trailer hitch assem-
bly weight, gross vehicle weight, gross
axle weight and tra iler tongue weight
capacities.
●Do not use the following systems when
trailer towing.
• Dynamic radar cruise control with full-speed range
• LTA (Lane Tracing Assist)
• PCS (Pre-Collision System)
• BSM (Blind Spot Monitor) (if equipped)
●Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts while descendi ng steep or long
downhill grades.

1784-2. Driving procedures
*1: Shifting to the D position allows the sys-tem to select a gear suitable for the
driving conditions. Setting the shift lever
to the D position is recommended for
normal driving.
*2: Selecting gears using M mode fixes the gear step, controls engine braking
force, and prevents unnecessary
upshifting.
■To protect the automatic transmission
If the automatic transmission fluid tempera-
ture is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on
the multi-information display and the vehi-
cle will go into transmission protection
mode automatically. Have the vehicle
inspected by your Lexus dealer.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not occur
NOTICE
■To prevent battery discharge
Do not stop the engine when the shift
lever is in a position other than P. If the
engine is stopped in another shift lever
position, the engine switch will not be
turned off but instead be turned to
ACCESSORY mode. If the vehicle is left
in ACCESSORY mode, battery dis-
charge may occur.

because dynamic radar cruise control with
full-speed range will not be canceled.
●While driving in D position, downshifting
to 7, 6, 5 or 4. ( P.227)
●When switching the driving mode to
sport mode while driving in the D position

■AI-SHIFT
●The AI-SHIFT automatically selects the
suitable gear accordin g to driver perfor-
mance and driving conditions.
The AI-SHIFT automatically operates
when the shift lever is in D. (Shifting the
shift lever to the M position cancels the
function.)
●G AI-SHIFT automatically selects a suit-
able gear for sporty driving according to
driver’s input and driving conditions. G
AI-SHIFT operates automatically when
the shift lever is in D and sport mode is
selected for the driving mode. (Selecting
normal mode with the driving mode
select switch or shifti ng the shift lever to
the M position cancels this function.)
While the engine switch is in IGNI-
TION 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 com-
pletely stopped.
■Shift lock system
The shift lock system is a system to prevent
accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only
when the engine swit ch is in IGNITION
ON mode and the brake pedal is being
depressed.
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is
being depressed.
If the shift lever cannot be shifted with your
foot on the brake pedal, there may be a
problem with the shift lock system. Have the
vehicle inspected by your Lexus dealer
immediately.
The following steps may be used as an
WARNING
■When driving on slippery road sur-
faces
Be careful of downshifting and sudden
acceleration, as this could result in the
vehicle skidding to th e side or spinning.
