The light comes on when the ignition key is turned to the “ON”
position. If the anti−lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti
−lock brake system, the brake
assist system, the traction control system and the vehicle
stability control system do not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti−lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.

With your foot off the accelerator pedal, crank the engine by
turning the key to “START”. Release it when the engine starts.
Engine should be warmed up by driving, not in idle. For
warming up, drive with the engine turning smoothly until engine
coolant temperature is within normal range.
