RX350_U_OM48E90U NOTICE ■
When driving the vehicle ●
Do not depress the accelerator and brake peda ls at the same time during driving, as
this may restrain driving torque. ●
Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill. ■
When parking the vehicle
Always shift the shift lever to P, set the parking brake. Failure to do so may cause the
vehicle to move or the vehicle may accelerate suddenly if the acce lerator pedal is acci-
dentally depressed. ■
Avoiding damage to vehicle parts ●
Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor. ●
When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc. ■
If you get a flat tire while driving
A flat or damaged tire may cause the follo wing situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.●
It may be difficult to control your vehicle. ●
The vehicle will make abnormal sounds or vibrations. ●
The vehicle will lean abnormally.
Information on what to do in case of a flat tire (  P. 646)■
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may cause the
following serious damage to the vehicle: ●
Engine stalling ●
Short in electrical components ●
Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following: ●
Brake function ●
Changes in quantity and quality of oil and fl uid used for the engine, transaxle, transfer
(AWD models), rear differential (AWD models), etc. ●

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 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. (if enabled, Trailer Sway Cont rol can also help 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 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.

Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle: ●
Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous places. ●
Do not grip the steering wheel spokes when driving off-road. A bad bump could jerk
the wheel and injure your hands. Keep both hands and especially your thumbs on the
outside of the rim. ●
Always check your brakes for effectivenes s immediately after driving in sand, mud,
water or snow. ●
After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these materi-
als trapped or adhering to the underb ody, a breakdown or fire could occur.●
When driving off-road or in rugged terrai n, do not drive at excessive speeds, jump,
make sharp turns, strike objects, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.
NOTICE ■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or other
components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompan ied by vibration, and ultimately damage.●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differential, tr ansmission and transfer (AWD models only)
case, reducing the gear o il’s lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated around brake discs may affect braking efficiency
and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.
