2044-1. Before driving
GS450h_300h_OM_OM30F92E_(EE)
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or rollforward while the shift lever is in R.Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving. Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward. Doing so can damage the transmission and may result in a loss of vehicle control.
●Shifting the shift lever to N while the vehicle is moving will disengage the hybrid sys- tem. Engine braking is not available with the hybrid system disengaged.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to any position other than P or N may lead to unexpected rapid accelera- tion of the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible. Rotor damage may result if the pads are not replaced when needed.
Front and rear* brakes: Moderate levels of brake pad and disc wear allow enhanced braking power. As a result, the discs may wear more quickly than conventional brakediscs. Therefore, when replacing the brake pads, Lexus recommends that you also
have the thickness of the discs measured. It is dangerous to drive the vehicle when th e wear limits of the brake pads and/or those of the brake discs are exceeded.
*: Except for Reunion, Canary Islands, Russi a, Ukraine, Israel, Turkey, Kazakhstan,
Georgia

■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.
