the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turn-
ing on slippery road surfaces
VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.

surfaces by controlling steering performance.
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
Hill-start assist control
Prevents the vehicle from rolling backward when starting on an incline
or slippery slope

If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the hybrid system.
If the shift lever cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehicle speed
as much as possible.
To stop the hybrid system, press
and hold the power switch for 2
consecutive seconds or more, or
press it briefly 3 times or more in
succession.

5048-2. Steps to take in an emergency
IS300h_EE(OM53B95E)
Before emergency towing
Release the parking brake.
Shift the shift lever to N.
Turn the power switch to ACCESSORY (hybrid system off) or ON (hybrid
system operating) mode.
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When transporting the vehicle
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress
on the emergency towing eyelets and the cables or chains. Always be cautious
of the surroundings and other vehicles while towing.
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
