Driving
■When starting off on a uphill
The hill-start assist control is available. (P. 3 0 8 )
■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, becau se 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.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is depressed while sport mode is selected ( P. 2 9 3 )
■Restraining engine output (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the engine
output may be restrained.
●A warning message is displayed on the multi-information display while the system is
operating. ( P. 4 8 0 )
■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 M) with the accelerator pedal depressed, a warning message appears on
the multi-information display. ( P. 4 6 4 )
• When the accelerator pedal is depressed to o much while the vehicle is in reverse.

Observe the following precautions.
Failure to do so may result in death or serious injury.
■If a brake pad wear warning message is displayed (GS F)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Moderate levels of the 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.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is any gear other than P or N, the vehicle may accelerate suddenly and
unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.
