the warning and indicator lamps illuminate. Wait for
three seconds before starting the engine.
The SAM Cab vehicle controller automatically cycles
all exterior lights off and then on when the head-
lamps are on and the park brake is released, or set.
This rapid flash of the exterior lights is a self-test to
detect any bulb that is not operational. Drivers may
notice all lights flash simultaneously during this pro-
cess. This is the normal operating sequence. A fault
code is set for any bulb that is out.
IMPORTANT: Do not crank the engine until the
ICU self-check is complete.
Turn the key clockwise past the ON position to reach
the START position to start the engine. Release the
key the moment the engine starts. Do not operate
the starter longer than thirty seconds, then allow the
starter to cool between attempts. If the starter over-
heats, the starter protection system will prevent op-
eration of the starter until it has cooled. Release the
key the moment the engine starts.
The ignition key also locks and unlocks the cab
doors, the baggage door(s) and if equipped, the bunk
door(s).

Fig. 5.3 for exterior light locations.
Auxiliary High Beam Lights
Auxiliary high-beam lights may be located in the front

Backup Lights
Backup lights activate only when the vehicle is in re-

Daytime Running Lights
The daytime running lights (DRL), if equipped, are
automatically activated when the ignition is switched
on and the parking brake is released. The DRL turn
off when the engine falls below 400 rpm, the parking
brake is applied, or the headlights are turned on.
Daytime running lights are mandatory for vehicles
domiciled in Canada. Vehicles domiciled in any other
location may have an optional override switch
(

ables the driver to deactivate the DRL. Press the
upper half of the switch briefly to activate or deacti-
vate the DRL.
Fog Lights
Fog lights are designed to reduce glare in foggy con-

trailer, as well as the turn signal indicators in the
ICU, flash simultaneously when the hazard lights are
activated.
