STARTING AND STOPPING

Starting

The pushbutton shift selector must be in the N
position or the engine will not start. If the
pushbutton shift selector is not in neutral, a
starter protection message will appear in the
DID along with the INFORMATION telltale and
an audible warning.

If there is not enough air pressure in the I-Shift
air tank, a low air supply message will appear in
the DID along with the INFORMATION telltale
light and an audible warning. Start the engine
and allow the air pressure to build in the tank.
Wait until the message and the telltale light turn
off before attempting to shift the transmission
into gear.

The brake pedal must be pressed down when
passing from the N position to another position
otherwise pressing the buttons will have no
effects.

Stopping

When parking the vehicle, always apply the
parking brake and place the pushbutton shift
selector to the N position. Make sure the
parking brake is holding the vehicle before
leaving the driver position. Failure to do so can
result in unexpected vehicle movement and can
cause serious personal injury or death.

When the vehicle is stopped:

1. Apply the parking brake.

2. Select the N position on the pushbutton shift

selector.

3. Turn off the engine.

STARTING THE VEHICLE UPHILL AND
DOWNHILL

Hilly Operating Conditions

When starting the vehicle on an uphill slope:

1. Press the brake pedal.

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 breakdown.

The I-Shift transmission clutch is a dry disc
type, with

no torque converter

. Never allow

the clutch to slip in a too high 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 pres-
sure in the brake chambers for 3 seconds after
the service brake pedal is released, which al-
lows time to the driver to move is foot from the
brake pedal to the accelerator pedal.
