after inflation pressure has been adjusted. ●
“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions. ●

Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area such as a
garage, exhaust gases includin g harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to death or a serious health hazard.
NOTICE ■
The multi-information disp lay at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed. ■
During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid syst em is operating while
setting up the display features.

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. ■

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 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

Please consult your dealer when installin g trailer lights, as incorrect installation
may cause damage to the vehicle’s lights. Please take care to comply with your
state’s laws when installing trailer lights.
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.Positions for towing hitch receiver and hitch ball 1

Matching trailer ball height to trailer coupler height
■
Before towing
Check that the followin g conditions are met:●
Ensure that your vehicle’s tires are properly inflated. (  P. 6 1 5 )●
Trailer tires are inflated according to the trailer manufacturer’s recommendation. ●
All trailer lights work as required by law. ●
All lights work each time you connect them. ●
The trailer ball is set at the proper height for the coupler on the trailer.●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, an d check for improper to ngue weight, overload-
ing, worn suspension, or other possible causes. ●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all applicable federal, state/provincial or local regula-
tions. If they do not, install rear view mirrors appropriate for towing purposes.No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.
