GAUGES
Speedometer:Indicates the
current vehicle speed.
Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between “H” and
“C”).If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine and let the engine cool.
Never remove the coolant reservoir cap while the engine is
running or hot.

Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area(over temperature) —
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the Yellow or Red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your authorized dealer.

The auxiliary power point is located
on the instrument panel.
On SuperCab and Crew Cab models,another power point is located
on the rear of the center console (if equipped).
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
Cigar lighter (if equipped)
Do not plug optional electrical accessories into the cigarette lighter
socket.
Do not hold the lighter in with your hand while it is heating, this will
damage the lighter element and socket. The lighter will be released from
its heating position when it is ready to be used.
Note:If the power point or cigar lighter socket is not working, a fuse
may have blown. Refer to theFuses and relaysin theRoadside
Emergencieschapter information on checking and replacing fuses.
Improper use of the lighter can cause damage not covered by your
warranty.

If equipped with powerfold mirrors,
you can fold the side mirrors
simultaneously using the power
mirror switch.
1. Rotate the switch to the center/neutral position.
2. Momentarily pull the switch rearward to auto fold in.
3. Momentarily pull the switch rearward again to fold back to design
position.
Note:When powerfolding the mirrors, it is normal to hear the sound of
the motors.
Mirror positions, from left to right: Position 1, Position 2, Position 3
The powerfold mirrors may be folded forward/rearward manually to any
of the three positions shown and electrically to positions 1 and 2 only. If
a mirror is folded manually forward to position 3, you must manually fold
it back to position 1 or 2 in order for the powerfold function to continue
functioning.
Note:Ten or more switch activations within one minute, or repeated
fold/unfolding of the mirrors while holding the switch rearward during
the full travel may cause the system to disable the fold/unfold function to
protect the motors from overheating. Should this occur, wait
approximately 3
1 2minutes for the system to reset and function to return
to normal.
Note:The powerfold mirrors are designed to operate while the vehicle is
stationary or traveling at moderate speeds. If you attempt to powerfold

Note:There are 30 seconds in which to initiate Step 7.
7. Return to the vehicle and firmlypress, hold for two seconds and
releasethe programmed HomeLinkbutton. Repeat the
press/hold/releasesequence again, and, depending on the brand of the
garage door opener (or other rolling code equipped device), repeat this
sequence a third time to complete the programming.
HomeLinkshould now activate your rolling code equipped device. To
program additional HomeLinkbuttons begin with Step 2 in the
“Programming” section. For questions or comments, please contact
HomeLinkatwww.homelink.comor1–800–355–3515.
Gate Operator & Canadian Programming
During programming, your
hand-held transmitter may
automatically stop transmitting —
not allowing enough time for
HomeLinkto accept the signal
from the hand-held transmitter.
After completing Steps 1 and 2
outlined in the“Programming”
section, replace Step 3 with the following:
Note:If programming a garage door opener or gate operator, it is
advised to unplug the device during the “cycling” process to prevent
overheating.
•Continue to press and hold the HomeLinkbutton (note Step 3 in the
“Programming” section) while you press and release —every two
seconds(“cycle”) your hand-held transmitter until the frequency
signal has been accepted by the HomeLink. The indicator light will
flash slowly and then rapidly after HomeLinkaccepts the radio
frequency signal.
•Proceed with Step 4 in the “Programming” section.

Note:If the engine does not start within five seconds on the first try,
turn the key to OFF, wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
If your vehicle has an automatic transmission,it will have a
computer assisted cranking system. This feature assists in starting the
engine. If the ignition key is turned to the 4 (START) position, and then
released when the engine begins cranking, the engine may continue
cranking for up to 10 seconds or until the vehicle starts
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.
USING THE ENGINE BLOCK HEATER (IF EQUIPPED)
Use of an engine block heater is
strongly recommended if you live in
a region where temperatures reach
-10°F (-23°C) or below. For best
results, plug the heater in at least
three hours before starting the
vehicle. The heater can be plugged
in the night before starting the
vehicle. The plug for the block
heater is exposed in the front of the
vehicle, beneath the grille. Vehicles
equipped with a gasoline engine have the plug exposed on the driver
side of the vehicle; vehicles equipped with a Diesel engine have the plug
exposed on the passenger side of the vehicle.
