IN CASE OF EMERGENCY335
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, follow the discon -
necting procedure.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper
cable from the engine ground of the vehicle
with the discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
vehicle with the discharged battery, and
reinstall the protective cap over the positive
(+) post. If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
Strong smell of coolant
White smoke coming from engine or exhaust
Coolant bottle coolant has bubbles present
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans
-
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.

4. Reinstall the access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then shift
back and forth between DRIVE (D) and REVERSE
(R), while gently pressing the accelerator. Use the least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning
the wheels or racing the engine.
NOTE:
For trucks equipped with an 8–speed transmis
-
sion, shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Push the ESC OFF button, to place the Electronic
Stability Control (ESC) system in “Partial Off”
mode, before rocking the vehicle Ú page 271.
Once the vehicle has been freed, push the ESC
OFF button again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it
is time to change your engine oil by displaying the
words “Oil Change Due” in your instrument cluster
display. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate depending on your
personal driving style. Failure to change the engine
oil per the maintenance schedule can result in
internal engine damage.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under instrument cluster display
Úpage 89. For Gasoline Engines, under no circumstances
should oil change intervals exceed 8,000 miles
(13,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern
for fleet customers.
For Diesel Engines, under no circumstances
should oil change intervals exceed 15,000 miles
(24,000 km) or 12 months, whichever comes first
or sooner if prompted by the oil change indicator
system.
NOTE:
It is recommended that every 3,000 miles
(4,800 km), check the engine oil level at least
30 minutes after a fully warmed engine is shut
off. Checking the oil level while the vehicle is on
level ground will improve the accuracy of the oil
level reading. Add oil only when the level is at or
below the ADD or MIN mark.
Severe service (high ambient temperature,
short trips, heavy loading, trailer towing,
off-road, or law enforcement use) may reduce
oil change intervals.
For Diesel Engines, configured with optional B20
capability are operated with greater than 5% levels
of biodiesel, the oil change interval must not
exceed 12,500 miles (20,000 km) or 400 hours,
whichever comes first under any circumstances.
See the Fuel Requirements section for more
information regarding operation with biodiesel
blend (B6-B20) fuel meeting ASTM specification
D-7467.
Perform Service Indicator — Diesel Engine
Your vehicle will require emissions maintenance at
a set interval. To help remind you when this
maintenance is due, the instrument cluster will
display “Perform Service”. When the “Perform
Service” message is displayed on the instrument
cluster it is necessary to have the emissions
maintenance performed. Emissions maintenance
may include replacing the Closed Crankcase
Ventilation (CCV) filter element. The procedure for
clearing and resetting the “Perform Service”
indicator message is located in the appropriate
Service Information.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
