Controls and Instruments 87
Hill Start Assist is only intended to temporarily
hold the vehicle on a grade before the vehicle is
put into motion. The vehicle brake must be
applied, independent of HILL START ASSIST, to
hold the vehicle on a grade for an extended
period of time.
When available, Hill Start Assist is enabled at
starting of the engine. The Hill Start Assist tell-
tale light in the instrument cluster will blink to
indicate that the feature is temporarily disabled.
If a Hill Start Assist fault occurs, the Hill Start
Assist telltale light in the instrument cluster will
illuminate and the feature is permanently un-
available until the fault is repaired.
When Hill Start Assist is enabled, it activates
automatically, but only when the following condi-
tions exist:
•
Vehicle speed is zero.
•
Vehicle is on an incline or decline greater
than 2%.
•
Shift selector is in the D position on an incline
or R position on a decline.
•
Service brake is applied.
•
ESC (Electronic Stability Control) is
functioning normally.
•
There has been no ESC activity in the
preceding stops.
When the service brake pedal is released, the
brakes are applied for approximately 3 seconds
or until the accelerator pedal is depressed,
whichever occurs first.
WARNING
Always apply parking brake before leaving
driver’s seat. The driver must not leave the
vehicle when the engine is running and a gear
is selected.
DRIVING
The most efficient way to operate the vehicle is
to use the automatic drive program, which is the
D position on the pushbutton shift selector. Gear
changing is automatic and the driver can
concentrate on the road ahead.
NOTE
When driving in automatic drive mode
(position D), the engine brake control should
be in the Auto mode
to maximize the
integration of the transmission and brake
system according to Eco-Roll mode. This
means optimum performance and fuel
economy at all times.
D Position
With the pushbutton shift selector in the D
position, the transmission will automatically
upshift and downshift as necessary to maintain
the desired vehicle speed for the current driving
conditions.
At starting of the vehicle, the gearbox selects
between gear 1-6 the most suitable start gear
with respect to weight and road’s gradient. The
driver can select a pulling away gear different
than the one selected by using the + and -
buttons.
When the vehicle is moving in automatic drive
mode, the driver can intervene manually, while
maintaining the accelerator pedal depressed, by
selecting a higher or lower gear using the + and
- buttons. The arrows in the display show how
many gears are available to change up or down.
Whenever gear changing is not desired while in
automatic drive mode, change the pushbutton
shift selector from D to M. No further gear
changes will be carried out and the current gear
will remain engaged.
CAUTION
There is a risk of over-revving the engine
when the transmission is locked in a gear.
Damage to the engine may occur. To lock the
transmission in the current gear, change the
pushbutton shift selector from the D position
to the M position. This function can be used
for all 12 forward gears. To return to the
automatic drive mode, set the pushbutton shift
selector back to the D position.
M Position
It is possible to drive the vehicle with full manual
gear changing or take over from the automatic
gear changing system whenever required. Gear
changing is done by first selecting the manual
position M.
