Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the switch) is rotated to the
upward detent position, or if equipped, when the UN-
LOCK button is pressed on the key fob. When a door isopen and the interior lights are on, rotating the dimmer
control all the way down to the OFF detent will cause all
the interior lights to go out. This is also known as the
Partymode because it allows the doors to stay open for
extended periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are ON you can
supplement the brightness of the odometer, trip odom-
eter, radio and overhead console by rotating the control
up until you hear a click. This feature is termed the
“Parade” mode and is useful when headlights are re-
quired during the day.
Quad Cab models may have an optional switched dome
lamp that may be operated by pressing the lens.

JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or fabrics.
Do not lean over a battery when connecting jumper
cables or allow cable clamps to touch each other.
Keep open flames or sparks away from battery vent
holes. Always wear eye protection when working
with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.NOTE:Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
Your vehicle is equipped with two 12–volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle’s engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
With Portable Starting Unit
There are many types of these units available. Follow the
manufacturer’s instructions for necessary precautions
and operation.
CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12 Volts D.C. or damage to
battery, starter motor, alternator, or electrical system
may occur.
FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE
(automatic transmissions) and between 1st and RE-
VERSE (manual transmissions), while applying slight
pressure to the accelerator.
In general, the least amount of accelerator pedal pressure to
maintain the rocking motion without spinning the wheels
or racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
402 WHAT TO DO IN EMERGENCIES

The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.
Maintenance Free Batteries
The top of the maintenance free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Don’t allow battery fluid
to contact your eyes, skin or clothing. Don’t lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Don’t use a
booster battery or any other booster source with an
output greater than 12 volts. Don’t allow cable
clamps to touch each other.
•Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
