■When starting off on a uphill
The hill-start assist control is available. ( P. 325)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary
to refrain from activities such as sudden acceleration, etc. Refer to “Hybrid vehicle driv- ing tips”. ( P. 331)
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Restraining hybrid system outp ut (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the hybrid sys-
tem output may be restrained.
●A warning message is displayed on the mult i-information display while the system is operating. ( P. 485)
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the hybrid system output may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D includes S) with the accelerator pedal depressed, a warning message appears onthe multi-information display. ( P. 473)
• When the accelerator pedal is depressed t oo much while the vehicle is in reverse.
●While Drive-Start Control is being activated, your vehicle may have trouble escaping
from the mud or fresh snow. In such case, deactivate TRC ( P. 326) to cancel Drive- Start Control so that the vehicle may become able to escape from the mud or freshsnow.

■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recommended:
●For the first 300 km (186 miles):
Avoid sudden stops.
●For the first 800 km (500 miles): Do not tow a trailer.
●For the first 1000 km (621 miles):
• Do not drive at extremely high speeds. • Avoid sudden acceleration.
• Do not drive continuously in low gears. • Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parkin g brake system. This type of brake system needs bedding-down of the brake shoes periodically or whenever the parking brakeshoes and/or drum are replaced. Have any au thorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer perform the bedding down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( P. 549)

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.

■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gaso line engine is cold, the gasoline engine will start automatically in order to warm up. In th is case, you will become unable to switch to
EV drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the fol- lowing situations. When EV drive mode is can celed, a buzzer will sound and the EV drive
mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low. The remaining battery level indicated in the “Energy monitor” display is low. ( P. 126)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters to approxi-
mately 1 km (0.6 mile). However, dependin g on vehicle conditions, there are situations when EV drive mode cannot be used. (The distance that is possible depends on the hybrid battery [traction battery] level and
driving conditions.)
■Fuel economy
The hybrid system is designed to achieve the best possible fuel economy during normal
driving (using the gasoline engine and electr ic motor [traction motor]). Driving in EV drive mode more than necessary may lower fuel economy.
To prevent gasoline engine warm up in order to
reduce noises, start the hybrid system without starting the gasoline engine, pressing the powerswitch with fully depressing the brake pedal and
pressing the EV drive mode switch.
WARNING
■Caution while driving
When driving in EV dr ive mode, pay special attention to the area around the vehicle. Because there is no engine noise, pedestrian s, people riding bicycles or other people
and vehicles in the area may not be aware of the vehicle starting off or approaching them, so take extr a care while driving.
