2-1. Driving procedures

When driving
ES350_U
CAUTION
●Do not turn the engine off while driving.
The power steering and brake booster systems will not operate properly if the
engine is not running.
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (oP. 1 2 8 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may 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
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.

2-1. Driving procedures
ES350_U
CAUTION
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering pump
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.

Power steering fluid■ Fluid level
The fluid level should be within the appropriate range.
Full (when cold)
Add fluid (when cold)
Full (when hot)
Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 min- utes, or slightly longer in frigid temperatures. (Fluid tempera-
ture, 140 qF - 175 qF [60 qC - 80 qC])
Cold: Engine has not been run for about 5 hours. (Room tempera- ture, 50 qF - 85q F [10qC - 30 qC])
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted
surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■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 frequent refilling, it may indicate a serious problem.
