DIESEL EXHAUST BRAKE (ENGINE BRAKING)
The Exhaust Brake switch is located on the switch bank below the audio system. This
switch is used to enable exhaust brake modes.
• Pressing the exhaust brake switch once will enable full strength exhaust brakemode, indicated by a yellow icon in the EVIC. This mode applies full exhaust
braking when the accelerator pedal is released. This is most useful for slowing the
vehicle.
• Pressing the exhaust brake switch again will enable the Smart Brake feature, indicated by a green icon in the EVIC. This feature is intended to maintain the
vehicle speed present when the accelerator pedal is released. However, when the
brakes are applied, full exhaust braking is still enabled to slow the vehicle.
• A third press of the brake switch will turn the exhaust brake off, and will extinguish the exhaust brake icon in the EVIC.
NOTE:
In general, higher engine speeds result in higher exhaust braking force. For optimum
braking power, it is recommended to use the exhaust brake while in TOW/HAUL
mode.
CAUTION!
Use of aftermarket exhaust brakes is not recommended and could lead to engine
damage.
WARNING!
Do not use the exhaust brake feature when driving in icy or slippery conditions as
the increased engine braking can cause the rear wheels to slide and the vehicle to
swing around with the possible loss of vehicle control, which may cause a collision
possibly resulting in personal injury or death.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low EVIC display.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.

- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However, the
conventional brake system will continue to operate normally if the BRAKE warning light
is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
- SERV (Service) 4WD Indicator Light
The SERV 4WD light monitors the electric shift four-wheel drive system. If the SERV
4WD light stays on or comes on during driving, it means that the four-wheel drive
system is not functioning properly and that service is required.
For vehicles equipped with a premium cluster this indicator will display in the
Electronic Vehicle Information Center (EVIC).

• Remove the jack and tool bracket assembly by removing the wing bolt and slidingthe jack and tool bracket assembly from under the seat.
Removing The Spare Tire
• Remove the spare tire before attempting to jack up the truck. Attach the wheelwrench to the jack extension tube. Insert the tube through the access hole between
the lower tailgate and the top of the bumper and into the winch mechanism tube.
Rotate the wheel wrench handle counterclockwise until the spare tire is on the
ground with enough cable slack to allow you to pull it out from under the vehicle.
When the spare is clear, tilt the retainer at the end of the cable and pull it through
the center of the wheel.
NOTE:
Always stow the spare tire with the valve stem facing the ground.
• It is recommended that you stow the flat or spare to avoid tangling the loose
cable.
NOTE:
The winch mechanism is designed for
use with the jack extension tube only.
Use of an air wrench or other power tools
is not recommended and can damage the
winch.
