Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale
LightWhat It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
light will illuminate when the ignition is in the ON 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, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral typical driving styles. In most situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be ser-
viced as soon as possible if this occurs.

formation.
Transmission Temperature Indicator Light
Red Telltale
LightWhat It Means
Transmission Temperature Indicator Light
This light indicates that the transmission fluid temperature is running hot. This may occur with
severe usage, such as trailer towing. If this light turns on, safely pull over and stop them ve-
hicle. Then, shift the transmission into NEUTRAL and run the engine at idle or faster until the
light turns off.

REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking
brake and shift the transmission into PARK if you must
leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
494 STARTING AND OPERATING
Page 497 of 916

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), select TOW/HAUL mode
or use the Electronic Range Select (ERS) shift control
(refer toElectronic Range Select (ERS) Operationin this
section for further information) to select a lower gear
range. Under these conditions, using a lower gear range
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be
illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
