2. Select the D position on pushbutton shift
selector. The driver can use the – button to
select a lower start gear if wanted.
3. Quickly move your foot from the brake pedal and
completely depress the accelerator pedal.
CAUTION
Always use the brakes to hold the vehicle
stationary on an uphill stop. Never hold the vehicle
stationary on an uphill slope using the accelerator
pedal. The clutch could overheat, which could
cause it to break down.
The I-Shift transmission clutch is a dry disc type,
with no torque converter. Never allow the clutch to
slip in too high a gear when starting the vehicle. If
the clutch overheats, a high clutch load message
or clutch protection active message will appear in
the DID along with the Check telltale light and an
audible warning.
DANGER
The vehicle can roll when stopped on a hill or
grade, or when the vehicle is starting from a stop
on a hill or grade. Always use the brakes to hold
the vehicle stationary on a hill or grade. Failure to
do so can result in serious personal injury or death.
Hill Start Assist
Hill Start Assist provides anti-roll assistance during
the transition from standing still to starting on a
grade. The brake system maintains pressure in the
brake chambers for 3 seconds after the service
brake pedal is released, which allows time for the
driver to move his foot from the brake pedal to the
accelerator pedal.
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 telltale
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 unavailable until the fault is
repaired.
When Hill Start Assist is enabled, it activates
automatically, but only when the following conditions
exist:
l Vehicle speed is zero.
l Vehicle is on an incline or decline greater than
2%.
l Shift selector is in the D position on an incline
or R position on a decline.
l Service brake is applied.
l ESC (Electronic Stability Control) is
functioning normally.
l 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
