Drive Systems
All-Wheel Drive
Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on the system,
replace the compact spare with a
full-size tire as soon as possible.
See Compact Spare Tire on
page 10‑75 for more information.
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 5‑17.

on hills depends upon the vehicle
speed, load, and the steepness of

downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle's speed. When the brakes
are applied the cruise control is
disengaged.Ending Cruise Control

control:
.To disengage cruise control;
step lightly on the brake pedal or

For vehicles with this feature, read
the following section before using it.
The Forward Collision Alert (FCA)
system may help to avoid or reduce
the harm caused by front-end

visual alert and beeps when
approaching a vehicle directly
ahead too quickly. FCA also
provides a visual alert if following
another vehicle much too closely.
The FCA symbol is on top of the
instrument panel to the right of the
steering wheel.
