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.
IDLE-UP FEATURE (AUTOMATIC TRANSMISSION ONLY)
•The Idle-Up Feature uses the speed control switches to increase engine idle speed
and quickly warm the vehicle’s interior. This feature must be enabled by your dealer.
See your local dealer.
•With the transmission in PARK, the parking brake applied, and the engine running,
push the speed control ON/OFF switch on, then push the SET switch.
• The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the RESUME/ACCEL switch and the idle speed will increase to approximately
1500 RPM. To decrease the RPM, push and hold the SET/DECEL switch and the
idle speed will decrease to approximately 1100 RPM.
• To cancel the Idle Up Feature, either push the CANCEL switch, push the ON/OFF switch or push the brake pedal.
DIESEL

•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.
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.
