RKE Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your vehicle can be
lowered by pushing the Key Fob air suspension
lowering button two times. When Remote key
FOB lowering is requested, the vehicle will
send a series of chirps and flashes to alert the customer
that the operation has begun and will continue these
alerts until it successfully lowers.
The following conditions must be met for the vehicle to
lower remotely:
• The vehicle must not already be in Entry/Exit (Park)
ride height.
• The vehicle battery must be fully charged.
• All doors must be closed.
• The ignition key must be out of the vehicle. Cancelling Remote Lowering
Vehicle lowering can be cancelled at anytime. When
vehicle lowering is cancelled, the vehicle will raise up to
the next defined level and lock out the remote lowering
feature until the ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the Key Fob air suspen-
sion lowering button one time during the lowering
process. When vehicle lowering is cancelled, the horn
will chirp two times and the hazard lights will flash four
times. Once raising is completed, the horn will chirp one
time.
NOTE:
Refer to “Air Suspension System” in “Starting
And Operating” for further information.

3. Remove the battery by turning the back cover over(battery facing downward) and tapping it lightly on a
solid surface such as a table or similar, then replace the
battery. When replacing the battery, match the + sign
on the battery to the + sign on the inside of the battery
clip, located on the back cover. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it
with rubbing alcohol.
4. To assemble the RKE transmitter case, snap the two halves together, reposition and secure the screw as
shown in step #2 for removal.

NOTE:If BeltAlert has been deactivated, the Seat Belt
Reminder Light will continue to illuminate while the
driver ’s or outboard front passenger ’s (if equipped with
BeltAlert) seat belt remains unbuckled.
Lap/Shoulder Belts
All seating positions except the Quad Cab®, Mega Cab®
and Crew Cab front center seating position have combi-
nation lap/shoulder belts.
The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the shoul-
der part of the seat belt to move freely with you under
normal conditions. However, in a collision the seat belt
will lock and reduce your risk of striking the inside of the
vehicle or being thrown out of the vehicle.
WARNING!
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work
with your seat belt to restrain you properly. In
some collisions, the air bags won’t deploy at all.
Always wear your seat belt even though you have
air bags.
• In a collision, you and your passengers can suffer
much greater injuries if you are not properly buck-
led up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.
• It is dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured
or killed.

The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenancefree, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
•
The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.

WARNING!(Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays, and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding seat
belt or retractor condition, replace the seat belt.

WARNING!
•If anyone in the vehicle could be in danger (e.g.,
fire or smoke is visible, dangerous road conditions
or location), do not wait for voice contact from a
9-1-1 operator. All occupants should exit the vehicle
immediately and move to a safe location.
• Never place anything on or near the vehicle’s
wireless and GPS antennas. You could prevent
wireless and GPS signal reception, which can pre-
vent your vehicle from placing an emergency call.
Wireless and GPS signal reception is required for
the 9-1-1 Call system to function properly.
• The 9-1-1 Call system is embedded into the vehi-
cle’s electrical system. Do not add aftermarket
electrical equipment to the vehicle’s electrical sys-
tem. This may prevent your vehicle from sending a

WARNING! (Continued)
signal to initiate an emergency call. To avoid inter-
ference that can cause the 9-1-1 Call system to fail,
never add aftermarket equipment (e.g., two-way
mobile radio, CB radio, data recorder, etc.) to your
vehicle’s electrical system or modify the antennas
on your vehicle. IF YOUR VEHICLE LOSES BAT-
TERY POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND SERVICES,
AMONG OTHERS, WILL NOT OPERATE.
• Modifications to any part of the 9-1-1 Call system
could cause the air bag system to fail when you
need it. You could be injured if the air bag system
is not there to help protect you.

hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked. If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the ABS, are also equipped with
Electronic Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn on
along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off

The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
25. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
