Engine Coolant
Temperature Gauge
Base Level Standard Theme Shown
Balanced Configuration Shown
This gauge measures the engine
coolant temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning
area or the shaded thermostat symbol,
the engine may be too hot.
Under some driving conditions,
including those listed below, it is
normal for the temperature to rise
above the usual operating range and
approach the far end of the gauge:
. Stop and go driving in heavy
traffic. .
High speed operation in warm
weather.
. Uphill driving.
. Trailer towing or hauling a
heavy load.
It is normal for the reading to
fluctuate.
If the gauge pointer reaches the
warning area or the shaded
thermostat symbol at the far end of
the gauge and remains there for more
than 30 seconds, the engine coolant
has overheated.
If the engine coolant has overheated,
pull over and stop the vehicle as soon
as it is safe to do so. Then, turn the
engine off immediately.
See Engine Overheating 0259.

the ignition is in Service Only Mode.
SeeIgnition Positions 0195.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0245.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless funnel
adapter, make sure that it has
been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0240. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed

164 LIGHTING
To enable the IntelliBeam system,
press the button on the end of the
turn signal lever when the exterior
lamp control is in the AUTO or
2
position. The blue high-beam on light
appears on the instrument cluster
when the high beams are on.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
There is a sensor near the top center
of the windshield that automatically
controls the system. Keep this area of
the windshield clear of debris to allow
for best system performance.
The high-beam headlamps remain on,
under the automatic control, until one
of the following situations occurs:
.The system detects an
approaching vehicle's headlamps.
. The system detects a preceding
vehicle's taillamps.
. The outside light is bright enough
that high-beam headlamps are not
required. .
The vehicle's speed drops below
20 km/h (12 mph).
. The IntelliBeam system is disabled
by the high/low-beam changer or
the flash-to pass feature. If this
happens, press the button on the
end of the turn signal lever to
reactivate the IntelliBeam system.
The instrument cluster light will
come on to indicate the
IntelliBeam is reactivated. See
Headlamp High/Low-Beam Changer
0164 and Flash-to-Pass 0165.
The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps because
of any of the following:
. The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
. The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
. The other vehicle's lamps cannot
be detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions. .
The vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view of
the light sensor.
. The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and
not detect headlamps and
taillamps.
. Driving on winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.

instrument panel. Do not cover the
sensor.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system changes to the DRL. During
that delay, the instrument cluster may
not be as bright as usual. Make sure
the instrument panel brightness
control is in the full bright position.

might need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle0299.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can carry.
This weight is called the vehicle
capacity weight and includes the
weight of all occupants, cargo, and
all nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR),
or either the maximum front or
rear Gross Axle Weight Rating
(GAWR). This can cause
systems to break and change
(Continued)
Warning (Continued)
the way the vehicle handles.
This could cause loss of control
and a crash. Overloading can
also reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the tire size of
the original equipment tires (3)
and the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
see
Tires 0276 and Tire
Pressure 0279.
There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certification Label” later
in this section.
