• Aero Mode (Lowers the vehicle approximately 0.6 in (15 mm) – This positionprovides improved aerodynamics by lowering the vehicle. The vehicle will auto-
matically enter Aero Mode when the vehicle speed remains between 52 mph
(83 km/h) and 56 mph (90 km/h) for greater than 20 seconds or if the vehicle
speed exceeds 56 mph (90 km/h). The vehicle will return to NRH from Aero Mode
if the vehicle speed remains between 20 mph (32 km/h) and 25 mph (40 km/h) for
greater than 20 seconds or if the vehicle speed falls below 20 mph (32 km/h). The
vehicle will enter Aero Mode, regardless of vehicle speed if the gear selector is in
the “SPORT” position.
• Transport Mode — To assist with flat bed towing, the air suspension system has a feature which will put the vehicle into Entry/Exit height and disable the automatic
load leveling system. Refer to “Programmable Features" (Uconnect Customer
Programmable Features) in “Electronics” for further information. Transport Mode
is selectable within the Suspension features.
NOTE:
This mode is intended to be enabled with engine running.
WARNING!
• You or others could be injured if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking
brake. The transfer case N (Neutral) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move regardless of
the transmission position. The parking brake should always be applied when
the driver is not in the vehicle.
• The air suspension system uses a high pressure volume of air to operate the
system. To avoid personal injury or damage to the system, see your authorized
dealer for service.
HILL START ASSIST/HILL DESCENT CONTROL/SELEC
SPEED CONTROL — IF EQUIPPED
• The Hill Start Assist system assists the driver when starting a vehicle from a stopon a hill.
• The Hill Descent Control system maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD LOW range.
• The Selec Speed Control feature allows the driver to travel at slow speeds on level ground, uphill or downhill without actively controlling either the throttle or brake.
• Refer to your Owner's Manual on the DVD for further details.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significantweight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the gear selector is in the PARK position.
3. Press and hold the brake pedal while pushing the ENGINE START/STOP button once and the system will engage the starter to crank the engine.
NOTE: • A delay of the start of up to five seconds is possible under very cold conditions.The “Wait to Start” telltale will be illuminated during the pre-heat process,
When the engine Wait To Start light goes off the engine will automatically crank.
• If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
4. Check that the oil pressure warning light has turned off.
5. Release the parking brake.

– Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will
come on when the ignition switch is turned to the ON/RUN position. It should go out
with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your
authorized dealer as soon as possible to have the problem diagnosed and corrected.
NOTE:
• The “ESC Off Indicator Light” and the “ESC Activation/Malfunction IndicatorLight” come on momentarily each time the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.

Preparations For Jump-Start
The battery in your vehicle is located under the passenger's front seat. There are
remote locations located under the hood to assist in jump-starting.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It canstart anytime the ignition switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch bands and bracelets that could
make an inadvertent electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
