164 3-4. Adjusting the steering wheel and mirrors
NX300h_U_OM78007U When the mirror select switch is in the “L” or “R” position, the outside rear view
mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, move the mirror select switch to the neutral position
(between “L” or “R”) ■
Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time. The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, th e tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.■
Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode. ■
When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. (  P. 4 3 5 )■

Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When driving the vehicle ●
During normal driving, do not turn off the hybrid system. Turning the hybrid system off
while driving will not cause loss of steering or braking control, however, power assist
to the steering will be lost. This will make it more difficult to steer smoothly, so you
should pull over and stop the vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the vehicle in
the normal way:  P. 5 5 7●
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 0 8 )●
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 hybrid
system 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.

Driving
NX300h_U_OM78007U NOTICE ■
When driving the vehicle ●
Do not depress the accelerator and brake pedals at the same time during driving, the
hybrid system output may be restrained. ●
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 brake 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. 5 7 5 )■
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 fluid used for the engine, hybrid transmis-
sion, etc. ●
Lubricant condition for the bearings and susp ension joints (where possible), and the
function of all joints, bearings, etc.

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differential 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. ●
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 pre-
vent instability. Remember that swaying of the towing vehicle-trailer increases as
speed increases.
