For more information, see “Off-road driv-
ing” (
컄 page 306).
The DSR is an aid for driving downhill. DSR
regulates your vehicle’s speed when driv-
ing downhill to the value set in the control
system (
컄
page 176). The steeper the
downhill gradient is, the greater the brake
application. On flat road surfaces, DSR
brakes only slightly or not at all.
DSR regulates the vehicle’s speed in auto-
matic transmission positions
D , or R .
You can drive slower or faster than the set
speed at any time by braking the vehicle or
depressing the accelerator pedal.
i
Whenever DSR is switched on, DSR will
use the programmed default speed to
regulate the vehicle’s speed. The de-
fault speed programmed at the factory
is 4 mph (Canada: 6 km /h). The de-
fault speed can be reprogrammed us-
ing the control system (
컄
page 176).
The next time DSR is switched on, DSR
will use the newly programmed default
speed to regulate the vehicle’s speed.
Once DSR is switched on, you can ad-
just the set speed using the cruise con-
trol lever (
컄
page 238). Keep in mind
that adjusting the set speed using the
cruise control lever with DSR switched
on will not change the programmed de-
fault speed. If DSR is switched off and
then switched on again, DSR will use
the programmed default speed.
Whenever the DSR is switched on, the
programmed default speed will be
used. That value can be changed
through the multifunction display. The
next time the DSR is switched on, it will
use that newly programmed default
speed.
Depending on the road surface and lev-
el of downhill grade, the DSR may not
be able to maintain the set speed. To
maintain the set speed, apply the
brakes if necessary.
