Driving
RX350_U_OM48E90U WA R N I N G
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 th e 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 posture 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 righ t foot. Depressing the brake pedal using
your left foot may delay response 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 engine off while driving
will not cause loss of steering or braking co ntrol, but the power assist to these systems
will be lost. This will make it more difficul t 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. 6 2 5●
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. 2 2 9 )●
Do not adjust the positions of the steering wh eel, 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, heads 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/electronic components to short circuit, damage the engine or
cause other serious damage to the vehicle. ●
Do not drive in excess of the speed limit. Ev en if the legal speed lim it 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 not before driving at such speeds.

Things that must not be carri ed in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:●
Receptacles containing gasoline ●
Aerosol cans ■
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block the
driver’s vision, or may result in items hittin g the driver or passengers, possibly causing
an accident. ●
Stow cargo and luggage in the luggage compartment whenever possible. ●
Do not stack cargo and luggage in the luggage compartment higher than the seat-
backs. ●
When you fold down the rear seats, long items should not be placed directly behind
the front seats. ●
Never allow anyone to ride in the luggage compartment. It is not designed for pas-
sengers. They should ride in their seats with their se at belts properly fastened.●
Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or re ar seats (when stacking items)
•On the luggage cover
• On the instrument panel
•On the dashboard ●
Secure all items in th e occupant compartment.■
Capacity and distribution ●
Do not exceed the maximum axle weight ra ting or the total vehicle weight rating. ●
Even if the total load of occupant’s weight and the cargo load is less than the total load
capacity, do not apply the load unevenly. Improper loading may cause deterioration
of steering or braking control which may cause death or serious injury. ■
Roof luggage carrier precautions
Observe the following precautions: ●
Place the cargo so that its weight is distributed evenly between the front and rear
axles. ●
If loading long or wide cargo, never exce ed the vehicle overall length or width.
(  P. 6 74 ) ●
Before driving, make sure the cargo is secu rely fastened on the roof luggage carrier.●
Loading cargo on the roof luggage carrier will make the center of gravity of the vehi-
cle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may result in loss of control or vehicle rollover due to failure
to operate this vehicle correctly and result in death or serious injury. ●
If driving for a long distance, on rough roads, or at high speeds, stop the vehicle now
and then during the trip to make sure the cargo remains in its place. ●
Do not exceed 165 lb. (75 kg) cargo weight on the roof luggage carrier.

212 4-1. Before driving
RX350_U_OM48E90U 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 trailer vary by state or province. Do not exceed the
posted towing speed limit. ●
Lexus recommends that the vehicle-trailer speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exceed 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 increases. 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 accustomed 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 without 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 traile r jackknifing and a
loss of vehicle control. This is especially true on wet or slippery surfaces. ●
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 traile r wheels will be closer than the vehicle
wheels to the inside of the turn. Comp ensate 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 forget the length of your trailer, and be
sure you have plenty of room before changing lanes.Trailer towing tips
