RX350_U_OM48E90U WA R N I N G ■
Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance with the
trailer’s characteristics and op erating conditions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance 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, unbrak ed TWR, GCWR, GVWR or GAWR.●
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with suffi-
cient capacity is required. ●
Adjust the tongue weight within the approp riate 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, whichever is lowest. Slow
down sufficiently before making a turn, in cr oss winds, on wet or slippery surface, etc.
to help avoid an accident. If you experience a vehicle-trailer instability from reducing
a certain speed, slow down and make sure you keep your vehicle speed under the
speed of which you expe rience the instability.●
Do not make jerky, abrupt or sharp turns. ●
Do not apply the brakes suddenly as you ma y skid, resulting in ja ckknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces. ●
Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities. ●
Do not use the following systems when trailer towing.
•Cruise control
*• Dynamic radar cruise control
*• Dynamic radar cruise cont rol with full-speed range
*• LDA (Lane-Departure Alert with steering control)
*• LKA (Lane-Keeping Assist)
*• PCS (Pre-Crash Safety system)
*• BSM (Blind Spot Monitor)
*
* : If equipped ●
Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descen ding steep or long downhill grades.●
Vehicle-trailer instability is more likely on steep long downhills. Before descending
steep or long downhill grades, slow down and downshift. Do not make sudden down-
shifts when descending stee p or long downhill grades. Avoid holding the brake pedal
down too long or applying the brakes too frequently. This could cause the brakes to
overheat and result in reduced braking efficiency. ●
Do not tow a trailer when the compact spare tire is installed on your vehicle.

S mode ●
When the shift range is 6 or lower, holding the shift lever toward “+” sets the shift range
to 8. ●
To prevent the engine from over-revving, upshifting may automatically occur. ●
To protect the automatic transmission, a function is adopted that automatically selects a
higher shift range when the fluid temperature is high. ■
To protect the automatic transmission
If the automatic transmission fluid temperat ure is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on th e multi-information display and the vehicle
will go into transmission protection mode automatically. Have the vehicle inspected by
your Lexus dealer. ■
Downshifting restrictions 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.) ■
When driving with cruise control, dynamic radar cruise control or 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 activate because cruise control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.●
While driving in D or S mode, downshifting to 7, 6, 5 or 4. (  P. 302, 314, 326)●
When switching the driving mode to spor t mode while driving in D position. (  P. 3 6 9 )■
Restraining sudden start (Drive-Start Control)
When the following unusual operation is performed, the engine output may be
restrained. ●
When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D includes S)
with the accelerator pedal depressed, a wa rning message appears on the multi-infor-
mation display. If a warning message is show n on the multi-information display, read the
message and follow the instructions.●
When the accelerator pedal is depresse d too while the vehicle is in reverse.
