when you start your vehicle to make sure the bulb works. If any light
remains on after starting the vehicle, refer to the respective system
warning light for additional information.
Note:Some warning lights are
reconfigurable telltale (RTT)
indicator lights and illuminate in the
message center. These lights
function the same as the other
warning lights.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light is also illuminated.
Brake system warning light:To
confirm the brake system warning
light is functional, it momentarily
illuminates when the ignition is
turned to the on position when the
engine is not running, or in a
position between on and start, or by
applying the parking brake when the
ignition is turned to the on position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It takes you longer to stop the vehicle. Have
the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.

Charging system:Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system or a related component. Contact your
authorized dealer as soon as possible.
Check fuel cap (gasoline engine
only):Illuminates when the fuel cap
may not be properly installed.
Continued driving with this light on
may cause the service engine soon
warning indicator to illuminate.
Check suspension (if equipped):
Illuminates when the air suspension
dump switch has been activated.
Check trans (Allison automatic
transmission only):Illuminates
while driving if a problem has been
detected and shifting may be
restricted. Depending upon the
severity of the problem, the
read-out digit on the shifter display
may be blank.
On MD 3000 series transmissions,operation may continue in order to
reach service assistance. The ECU may not respond to shift selector
requests, since operating limitations are being placed on the
transmission, i.e. upshifts and downshifts may be restricted. Direction
changes do not occur.
Refer to your transmission operator’s manual for more information.
Diesel exhaust fluid (diesel
engine only):Illuminates when the
diesel exhaust fluid level falls below
0.5 gallon (1.9L) in the 5 gallon
(19.0L) tank or 1 gallon (3.8L) in
the 9 gallon (34.0L) tank. Refill the
tank or, at a minimum, add at least
1 gallon (3.8L) to the 5 gallon
(19.0L) tank or 2 gallons (7.6L) to the 9 gallon (34.0L) tank.

Service engine soon:Illuminates
when the ignition is first turned to
the on position to check the bulb
and to indicate whether the vehicle
is ready for Inspection/Maintenance
(I/M) testing.
Solid illumination after the engine is
started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Speed control (if equipped):
Illuminates when the speed control
system is engaged. Turns off when
the speed control system is
disengaged.
Stop engine (diesel engine only):
This red lamp illuminates when the
engine needs to be stopped (as soon
as it can be safely done). If the lamp
begins flashing, automatic engine shutdown may take place in as little as
20 seconds.
WARNING:In the event of engine shutdown, make sure the
vehicle is safely off the road and the problem is remedied prior
to returning to the road. Failure to remove the vehicle from the road
could result in an accident, causing serious injury or death.
If the engine shuts down, it can be restarted and operated for
30 seconds at a time or until the problem is corrected. For more
information, refer toEngine automatic shutdown warning light or
chimein theDrivingchapter of this owner guide and/or your engine
operator’s manual.
Refer to your engine operator’s manual for specific information regarding
this feature. Drivers of electronically-controlled engines should know the
extent of warning engine shutdown system before operating the vehicle.

shown; metric similar
1.Tachometer:Indicates the engine speed in revolutions per minute.
Driving with your tachometer pointer continuously at the top of the scale
may damage the engine.
2.Engine oil pressure gauge:Indicates engine oil pressure. The
needle should stay in the normal operating range (between L and H). If
the needle falls below the normal range, stop the vehicle, turn off the
engine and check the engine oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked at your authorized dealer.
3.Engine coolant temperature gauge:Indicates engine coolant

AUXILIARY POWER POINT
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this can damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
•On the instrument panel (two locations)
•Inside the center console storage compartment (if equipped)
•On the rear of the center console (if equipped)
•Inside the 20-percent front seat console (if equipped)
•Inside the rear under seat storage compartment (if equipped)
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.

When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING:Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked. If your vehicle is operated in a heavy snow storm or blowing
snow conditions, the engine air induction may become partially clogged
with snow and/or ice. If this occurs, the engine may experience a
significant reduction in power output. At the earliest opportunity, clear
all the snow and/or ice away from the air induction inlet. The following
starting instructions are for vehicles equipped with a gasoline engine; if
your vehicle is equipped with a diesel engine, refer toStarting the
engine (diesel engine only)in this chapter.
Before starting the vehicle:
1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to theSeating
and Safety Restraintschapter.
2. Make sure the headlamps and electrical accessories are off.
3. Make sure the parking brake is set.
4. Make sure the gearshift is in P (Park).
5. Turn the key to 4 (on) without turning the key to 5 (start).
