For safety and security
WARNING
■Road accident cautions 
Observe the following precautions to reduce  the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and 
turn the hybrid system off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch the fluid as it may be strong alkaline electrolyte from the hybrid battery (traction battery). If it comes into contact with your skin or 
eyes, wash it off immediately with a large amount of water or, if possible, boric acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a 
fire extinguisher that is not meant for electric fires. Using even a small amount of water may be dangerous.
●If your vehicle needs to be towed, do so  with rear wheels raised. If the wheels con- 
nected to the electric motor (traction motor) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. ( P. 454)
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto 
the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible. 

1923-4. Adjusting the steering wheel and mirrors
GS450h_300h_OM_OM30F92E_(EE)
■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 clea red using the mirror defoggers. Turn on the 
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 352)
■Automatic adjustment of the mirror angle  
A desired mirror face angle can be entered to memory and recalled automatically by the 
driving position memory. ( P. 178)
■Auto anti-glare function 
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear 
view mirrors will activate in conjunction with  the anti-glare inside rear view mirror to reduce reflected light. ( P. 188)
■Using automatic mode in cold weather 
When automatic mode is used in cold weather, the door mirror could freeze up and automatic stowing and return may not be possible. In this event, remove any ice and snowfrom the door mirror, then either operate the mirror using manual mode or move the mir- 
ror by hand.
WARNING
■Important points while driving 
Observe the following precautions while driving. Failure to do so may result in loss of control of the vehicle and cause an accident, result- 
ing in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirrors must be extended and properly adjusted before driving.
■When a mirror is moving 
To avoid personal injury and mirror malfunction, be careful not to get your hand caught by the moving mirror.
■When the mirror defoggers are operating 
Do not touch the rear view mirror surfaces, as they can become very hot and burn you.

Trailer towing (vehicles without towing package)
Lexus does not recommend towing a trailer with your vehicle. Lexus also does 
not recommend the installation of a tow hitch or the use of a tow hitch carrier 
for a wheelchair, scooter, bicycle, etc.  Your vehicle is not designed for trailer

2104-1. Before driving 
GS450h_300h_OM_OM30F92E_(EE)
Trailer towing (vehicles with towing package)
◆Weight limits 
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC 
(Maximum Permissible Axle Capacity), and permissible drawbar load before 
towing. ( P. 546)
◆Towing hitch/bracket 
Lexus recommends the use of the Lexus hitch/bracket for your vehicle. Other 
products of a suitable nature and comparable quality may also be used.
Your vehicle is designed primaril y as a passenger carrying vehicle. 
Towing a trailer will have an adverse  effect on handling, performance, brak- 
ing, durability, and fuel consumption.  Your safety and satisfaction depend on 
the proper use of correct equipment  and cautious driving habits. For your 
safety and the safety of others, do not overload the vehicle or trailer. 
To tow a trailer safely, use extreme care and drive the vehicle in accordance 
with the trailer’s characteristics and operating conditions. 
Lexus warranties do not apply to damage or malfunction caused by towing a 
trailer for commercial purposes. 
Ask your local authorized Lexus retailer or Lexus authorized repairer, or any 
reliable repairer for further details before  towing, as there are additional legal 
requirements in some countries.
