Driving

WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When starting the vehicle
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rearview mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passeng ers’ arms, heads or other parts of their body are not outside the vehicle.
■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.
●After driving through a puddle, depress the brake pedal to make sure that the brakes
are functioning properly. Wet brake pads may prevent the brakes from functioning
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 roll forward while the shift lever is in R.
Doing so may result in an acci dent 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 D 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 av ailable when N is selected.
●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 accide nt 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.
Moderate levels of brake pad and disc wear allow enhanced braking power. As a
result, the discs may wear more quickly than conventional brake discs. 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 the wear limits of the brake pads and/or those of the brake discs are exceeded.
5127-3. Do-it-yourself maintenance
IS300h_EE(OM53D89E)
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe
the following precautions.
■When working on the engine compartment
●Make sure that the “ACCESSORY” or “I GNITION ON” on the multi-information
display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flamma-
ble.
●Take care because brake fluid can harm yo ur hands or eyes and damage painted sur-
faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the power switch is off. With the power switch in ON mode, the elec tric cooling fans may automatically start to
run if the air conditioning is on and/ or the coolant temperature is high. (P. 521)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner f ilter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs freq uent refilling, it may indicate a serious problem.
