■When starting off on an uphill
The hill-start assist control will activate. ( P. 352)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are simila r to conventional vehicles, and it is necessary
to refrain from activities su ch as sudden acceleration. (P. 358)
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and th e 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 the hybrid system ou tput (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 displaye d on the multi-information display while the system is
operating. If a warning message is shown on the multi-information display, read the message and follow the instructions.
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the engine 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 acce lerator pedal depressed, a warning message appears on the multi-information display. ( P. 595)
• 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. 354) to cancel Drive-
Start Control so that the vehicle may become able to escape from the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observin g 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 peri odically or whenever the parking brake
shoes 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 vehi cle registration laws and confirm the availability of the cor-
rect fuel. ( P. 646)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in oper-
ating the pedals. Make sure to operate the pedals properly. • Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay re sponse in an emergency, resulting in an accident.
●The driver should pay extra attention to pedestrians when the vehicle is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the v ehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials. The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●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. 567
●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. 226)

◆Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC
(Maximum Permissible Axle Capacity), and permissible draw bar load before
towing. ( P. 644)
◆Towing hitch/bracket
Lexus recommends the use of the Lexus hi tch/bracket for your vehicle. Other
products of a suitable nature and comparable quality may also be used.
◆To prevent an accident
The handling of the vehicle will feel diff erent when towing a trailer. Beware of
the 3 most common causes of towing-rel ated accidents: driver error, exces-
sive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running perfor-
mance, handling, fuel consumption and endurance of your vehicle. Use the
vehicle features in the correct manner and operate the vehicle with care for
safer driving and optimal comfort. Dama ge and/or malfunctions that occur as
a result of towing performed for comme rcial purposes are not covered by the
Lexus warranty.
Ask your local authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer for furthe r 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 gasoline engine is cold, the gasoline engine will start automatically after a short period of time in order to warm up. In this case, you will
become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illuminated, press the EV drive mode switch before the gasoline en gine starts 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 dr ive mode is canceled, 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. 128)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill, etc.
■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 2 km (1.2 mile). Howe ver, depending on vehicle conditions, there are situations
when EV drive mode cannot be used.
(The distance that is possible depends on th e 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 necess ary may lower fuel economy.
WARNING
■Caution while driving
When driving in EV drive mode, pay special attention to the area around the vehicle.
Because there is no engine noise, pedestrians, 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 extra care while driving.
