Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
• sudden loss of power
• unusual engine noises
• fuel, oil or coolant leaks
• sudden change, outside the normal operating range, in
the engine operating temperature
• excessive smoke
• oil pressure drop
ENGINE BLOCK/TRANSMISSION HEATER — IF
EQUIPPED
To ensure reliable starting/operating at these tempera-
tures, use of an externally powered electric engine block/
transmission heater (available from your authorized
dealer) is recommended.
The engine block heater warms engine coolant and
permits quicker starts in cold weather. The transmission
heaters warm gearbox oil and hydraulic actuation system
oil to operate in cold weather. Connect the heater cord to
a ground-fault interrupter protected 110–115 Volt AC
electrical outlet with a grounded, three-wire extension
cord.
Its use is recommended for environments that routinely
fall below -10°F (-23°C). It should be used when the
vehicle has not been running overnight or longer periods

and should be plugged in two hours prior to start. Its use
is required for cold starts with temperatures under -17°F
(-27°C).
In the case of LOW temperature after Starting, the
Automated Manual Transmission may not be able to
engage first gear. In this case a messageShift not
allowed appears. In this situation use the engine block
heater.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 Volt electrical cord could
cause electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
AUTOMATED MANUAL TRANSMISSION
WARNING!
You or others could be injured if you leave the
vehicle unattended without fully applying the park-
ing brake. The parking brake should always be
applied when the driver is not in the vehicle.
The automated manual transmission is a conventional
six-speed manual transmission with an electronically-
controlled hydraulic system that controls the clutch and
gear shifting. In forward gears, this transmission offers
two modes of operation:
• MANUAL (M) Mode — where the driver controls the
transmission shifting.
• Automatic Mode (the DRIVE [D] position)
— where
the electronic system controls the gear shifts.
46 STARTING AND OPERATING

•At low speeds you may hear mechanical noises similar
to a manual transmission as the transmission changes
gears. These noises are normal and will not damage
the transmission.
• Very aggressive driving may result in some clutch
odor. A warning message will display in the EVIC if
cool down actions are needed.
• Before and after the engine is started, you may hear a
hydraulic pump for a short period of time. This noise
is normal and will not damage the transmission.
• During extremely cold temperatures, the transmission
will not operate if the oil temperature is -22°F (-30°C)
or below. When transmission actuation oil temperature
is lower than -22°F (-30°C), engine start will not be
allowed by PCM. For this reason the block heater is
recommended below -17°F (-27°C). Normal operation
will resume once the transmission temperature has
risen to a suitable level.Manual (M) (Manual Mode)
In the MANUAL (M) position the driver is responsible
for choosing the best gear ratio to engage, depending on
driving conditions.
NOTE: Do not press the brake and accelerator pedals at
the same time. Use only one foot to operate the brake and
accelerator.
To operate in MANUAL (M) mode:
• Press and hold the brake pedal.
• Move the shift lever to the MANUAL (M) position.
The current gear will be displayed in the EVIC.
• To drive, release the brake pedal and press the accel-
erator pedal.
• Tap the shift lever towards the (+) to engage a higher
gear.

MESSAGEDESCRIPTION
Press Brake Pedal / Startup Delayed This messages appears when the key is first turned ON, if the brake pedal is
not depressed and/or the shift lever is not in NEUTRAL (N). The shift lever
must be in the NEUTRAL (N) position, and the brake pedal must be pressed,
to allow engine cranking. Place the shift lever in NEUTRAL (N) and apply the brake pedal BEFORE turning the key to the START/AVV position; otherwise,the engine will not crank and the key must be cycled OFF, then back on, be- fore cranking is allowed.
Gear Unavailable This message appears, along with a warning buzzer:
•When it is not possible to change gear due to a fault in the system.
• When, due a fault in the system, it is only possible to engage 1st (1), 2nd
(2), 3rd (3) or REVERSE (R).
Contact your authorized dealer if the message continues to appear.
Shift Not Allowed This message may appear when starting the engine at low temperature. In this case the Automated Manual transmission isn’t able to engage first gear, in thissituation either use the engine block/transmission heater or allow the engine to idle in NEUTRAL (N) until the transmission has warmed.
58 STARTING AND OPERATING

Perform the maintenance listed in the “Maintenance
Schedule.” Refer to “Maintenance Schedule” for the
proper maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can

WARNING! (Continued)
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. For four-wheel drive vehicles,
make sure the transfer case is not in NEUTRAL.
Always, block or chockthe trailer wheels.
• GCWR must not be exceeded.
