With the engine control switch in the
ON position, the fuel gauge
indicates about how much fuel is left
in the tank.
To check the fuel level with the
engine control switch in the LOCK
position, press the Odometer Check
switch.
Fill the tank well before it
approaches empty. After filling up
the fuel tank, it takes awhile for the
fuel gauge needle to stabilize after
the engine control switch is turned
to the ON position. If the fuel tank is
filled while the engine is off, but the
engine control switch is in the ON
position, the fuel gauge needle
takes awhile to show the correct
reading.
See“Low Fuel Warning Light” in
Driver Information Center (DIC)
(Diesel Only) 093 and Running Out
of Fuel (Diesel) 0238.Engine Coolant
Temperature Gauge
With the engine control switch in the
ON position, this gauge indicates
the temperature of the engine
coolant. “C”means cold while “H”
means hot. During operation, the
needle should stay in the safety
zone. See Engine Overheating
0 269.
{Warning
If the engine coolant temperature
gauge shows an overheat
condition or you have any other
reason to suspect the engine may
be overheating, continued
operation of the engine, even for
a short time, may result in a fire
and the risk of personal injury and
severe vehicle damage. Take
immediate action as outlined in
Engine Overheating. See Engine
Overheating 0269.
Caution
If the needle goes up above the
upper limit and enters the H zone,
the engine is likely to overheat.
Immediately pull safely off the
road out of the way of traffic and
take the necessary actions to
deal with engine overheating.
If the needle nears the H zone but
does not cross into it, this is not a

problem, but check the engine
coolant level in the reservoir. Add
engine coolant as necessary.

(DEF) Gauge
The DEF gauge is part of the Driver
Information Center (DIC). See
Driver Information Center (DIC)
(Diesel Only) 093.
Seat Belt Reminders
Seat Belt Warning Light
There is a driver seat belt reminder
light on the instrument cluster.
This warning light comes on and a
warning buzzer sounds when the
driver is not wearing the seat belt
while the engine control switch is in
the ON position.
When the vehicle speed exceeds
20 km/h (12 mph) with the seat belt
unbuckled, the warning light will
flash and the buzzer will continue to
sound. The warning light will go out
and the warning buzzer will stop
when the driver buckles the
seat belt.
Battery Warning Light
This light comes on briefly when the
ignition is turned on, but the engine
is not running, as a check to show
the light is working. It should go out
when the engine is started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system (such as a loose or broken
fan belt). Pull off to a safe place well
clear of traffic and contact your
dealer. Driving while this light is on
could drain the battery.
Check and Corrective Action
1. Check to see if the fan belt is broken or loose.
2. If the fan belt is loose, adjust the tension.
3. If the fan belt is broken or there is no abnormality in the fan
belt, see your dealer for
service.
See Battery 0281, Jump Starting -
North America 0326, and Engine
Drive Belt Routing 0396.

After driving in the overheated
engine protection mode, allow the
engine to cool before attempting
any repair to avoid engine damage.
The engine oil will be severely
degraded. Repair the cause of
coolant loss and change the oil. See
Engine Overheating0269.
High-Beam On Light
This light comes on when the
high-beam headlamps are in use or
the headlamps are cycled between
high and low beams (passing
signal).
See Headlamp High/Low-Beam
Changer 0104.
Daytime Running Lamps
(DRL) Indicator Light
This light comes on when the DRL
are on. If the vehicle is started
during the daytime with the lighting
switch off and the parking brake
released, the low beam headlamps
will come on at a reduced
brightness. The light will go out
when the lighting switch is
turned on.
See Exterior Lamp Controls 0103.
Cruise Control Light
This light should come on briefly
when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started.
For vehicles with cruise control, this
light comes on when cruise control
is turned on.
This light should come on briefly
when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started.
