DRIVING AND OPERATING 221
The transmission will not
automatically shift to the next higher
gear if the engine rpm is too high.
It will only automatically shift to the
next lower gear if the engine rpm is
much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode.
When the AWD feature is active, the
system transfers engine power,
if required, to all four wheels. The
system is fully automatic and adjusts
to road conditions for improved
traction and control. In FWD Mode
engine power is transferred to the
front wheels only, and the AWD
feature is off.
The AWD feature is automatically
activated when certain modes are
selected using the Driver Mode
Control switch. When an AWD mode
change is requested the light will flash
briefly while the system is engaging
and the AWD light will be displayed
when the system is active. When a
non-AWD Mode is selected, the light
will flash briefly while the system
disengages and a 2WD light will be
displayed when the AWD system is
off. See Driver Mode Control 0 225.
When a compact spare tyre is
installed on an AWD vehicle, the
system will automatically detect the
compact spare and reduce AWD
performance to protect the system. To
restore AWD operation and prevent
excessive wear on the system, replace
the compact spare with a full-size tyre
as soon as possible. See Compact Spare
Tyre 0 346.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake
boost have hydraulic brake circuits
that are electronically controlled when
the brake pedal is applied during
normal operation. The system
performs routine tests and turns off
within a few minutes after the vehicle
is turned off. Noise may be heard
during this time. If the brake pedal is
depressed during the tests or when
the electric brake boost system is off,
a noticeable change in pedal force and
travel may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while braking hard.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
0 108.
ABS does not change the time needed
to put your foot on the brake pedal
and does not always decrease stopping
distance. If you get too close to the
vehicle ahead, there will not be
enough time to apply the brakes if it
suddenly slows or stops. Always leave
enough room ahead to stop, even
with ABS.
