RX350/RX350L_U WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped engine running. This prevents
the vehicle from creeping. ■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay re sponse in an emergency, resulting in an accident.●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby. ●
During normal driving, do not turn off the engine. Turning the engi ne 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 the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way:  P. 645●
Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. (  P. 240)●
Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control. ●
Always check that all passengers’ arms, he ads or other parts of their body are not
outside the vehicle. ●
AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for of f-road driving. Proceed with all due cau-
tion if it becomes unavoidable to drive off-road. ●
Do not drive across a river or through other bodies of water.
This may cause electric/elect ronic components to short ci rcuit, damage the engine or
cause other serious damage to the vehicle. ●
Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h ) may result in tire failure , loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or no t before driving at such speeds.

Driving
RX350/RX350L_U WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When the vehicle is stopped ●
Do not race the engine.
If the shift lever is in any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident. ●
In order to prevent accidents due to the ve hicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary. ●
If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed. ●
Avoid revving or r acing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.■
When the vehicle is parked ●
Do not leave glasses, cigarette lighters, sp ray cans, or soft drink cans in the vehicle
when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cau se the plastic lenses and plastic mate-
rial of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the
vehicle, and may also cause a short circui t in the vehicle’s electrical components.●
Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as
the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire. ●
Do not attach adhesive discs to the windsh ield or windows. Do not place containers
such as air fresheners on th e instrument panel or dashbo ard. Adhesive discs or con-
tainers may act as lenses, ca using a fire in the vehicle.●
Do not leave a door or window open if th e curved glass is coated with a metallized
film such as a silver-colored one. Reflecte d sunlight may cause the glass to act as a
lens, causing a fire. ●
Always apply the parking brake, shift the shift lever to P, stop the engine and lock the
vehicle.
Do not leave the vehicle unattend ed while the engine is running.
If the vehicle is parked with the shift leve r in P but the parking brake is not set, the
vehicle may start to move, possibly leading to an accident. ●
Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns.

Driving
RX350/RX350L_U Your vehicle will handle differently when towing a trailer. Help to avoid an acci-
dent, death or serious injury, keep the following in mind when towing:●
Speed limits for towing a tr ailer vary by state or province. Do not exceed the
posted towing speed limit. ●
Lexus recommends that the vehicle-traile r speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exce ed this limit, the posted towing speed
limit or the speed limit for your trailer as set forth in your trailer owner’s man-
ual, whichever is lowest. Instability of the towing vehicle-trailer combination
(trailer sway) increases as speed incr eases. Exceeding speed limits may cause
loss of control. ●
Before starting out, check the trailer lights, tires and the vehicle-trailer con-
nections. Recheck after driving a short distance. ●
Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become acc ustomed to the feel of the vehicle-
trailer combination. ●
Reversing with a trailer attached is di fficult and requires practice. Grip the
bottom of the steering wheel and move your hand to the left to move the
trailer to the left. Move your hand to the right to move the trailer to right. (This
is generally opposite to reversing with out a trailer attached.) Avoid sharp or
prolonged turning. Have someone guid e you when reversing to reduce the
risk of an accident. ●
As stopping distance is increased when towing a trailer, vehicle-to vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length. ●
Avoid sudden braking as you may skid, re sulting in the trailer jackknifing and a
loss of vehicle control. This is especi ally true on wet or slippery surfaces.●
Avoid jerky starts or sudden acceleration. ●
Avoid jerky steering and sharp turns, an d 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 cross winds, 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 fo rget the length of your trailer, and be
sure you have plenty of room before changing lanes.Trailer towing tips

224 4-1. Before driving
RX350/RX350L_U ●
To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put th e transmission in D. If in the M or S
mode, the transmission shift range po sition must be in 6 or lower. (  P. 240)●
Instability happens more fr equently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep 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, yo ur 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 temperat ure 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. 692)●
Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Put the transmission in P and apply the parking brake. Avoid
parking on a slope, but if unavoidable, do so only after performing the follow-
ing:
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.
Shift into P and apply the parking brake.
Turn off the engine.●
When restarting afte r parking on a slope:
With the transmission in P, start the en gine. Be sure to keep the brake pedal
depressed.
Shift into a forward gear. If reversing, shift into R.
If the parking brake is in manual mode, release the parking brake.
(  P. 248)
Release the brake pedal, and slowly pull or back away from the wheel
blocks. Stop and apply the brakes.
Have someone retrieve the blocks. 1

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transaxle, transfer (AWD models), rear differential (AWD models) 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 requir e more frequent maintenance due to the addi-
tional load. (See “Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Scheduled Maintenance”.) ●
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 ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the st eering or brakes, your vehicle and trailer
should stabilize. (if enabled, Trailer Sway Control can also he lp to stabilize the vehicle and
trailer.) ●
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 ov erloaded 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.
