Drive Systems

All-Wheel Drive

If the vehicle has this feature,
engine power is sent to all four
wheels when extra traction is
needed. This is like four-wheel
drive, but there is no separate lever
or switch to engage or disengage
the front axle. It is fully automatic,
and adjusts itself as needed for road
conditions.
Brakes

Antilock Brake

System (ABS)

This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5 22.
