88 Instruments and Controls
Warning (Continued)
Even if a problem has occurred in
the ABS, the brakes will still work
as normal brakes. In this case,
the ABS has no influence on the
operation of the brake system.
See Brake System Warning Light
(Parking Brake Light) 084 and
Antilock Brake System (ABS) 0217.
Exhaust Brake Light
For diesel vehicles, this light comes
on when the exhaust switch is
pulled and the engine is running.
See Exhaust Brake (Diesel Only)
0 222.
Service Transmission
Warning Light
For diesel vehicles, this light comes
on briefly when the engine control
switch is in the ON position, as a
check
to show the light is working.
It should go out when the engine is
started.
If the warning light starts to blink
while driving, it indicates that there
is a malfunction in the automatic
transmission’s electronic control
system. If the warning light is
blinking, see your dealer for service.
Automatic Transmission
Fluid Temperature
Warning Light
For diesel vehicles, this light comes
on briefly when the engine control
switch is in the ON position, but the
engine is not running, as a check to
show the light is working. It should
go out when the engine is started.
The Automatic Transmission Fluid
(ATF) Temperature warning light
comes on if the ATF temperature is
high. This usually occurs when the
transmission is overfilled and may
be accompanied by leakage of fluid
from the transmission
breather hose.
If the light stays on, or comes on
while driving, slow down and pull off
the road. Stop the vehicle at a safe
place and put the vehicle in

P (Park). With the engine idling, wait
until the light goes off. If the light
goes off, you can drive the vehicle
again. If the light does not go off,
have the automatic transmission
lubricating system checked by your
dealer.
Caution
Driving with the ATF warning light
constantly on can cause serious
mechanical damage to the
automatic transmission.
See Automatic Transmission 0204.
Overdrive Off Light
(Diesel Only)
This light should come on briefly
when the engine control switch is
turned on as a check to make sure
the light is working. It should go out
automatically.
This light comes on when the
overdrive off switch on the selector
lever is turned on. Overdrive will not
operate even when the automatic
transmission is in D, unless engine
speed is excessive.
Wait-to-Start Light
For diesel vehicles, this light comes
on when the engine control switch is
turned to the ON position and goes
out when preheating is complete.
See Starting and Stopping the
Vehicle (Gasoline Only) 0165 or
Starting and Stopping the Vehicle
(Diesel Only) 0168.
Engine Oil Pressure 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.
This light comes on when the
engine oil pressure has fallen below
the normal level while the engine is
running or the oil pressure across
the oil filter rises above the normal
level while the engine is running.
If the warning light comes on while
driving, immediately pull off to a
safe place and stop the engine.
Check the oil level in the engine
crankcase. If the oil level is normal,
restrictions are in the oil filter or
within the lubricating system. Have
the vehicle inspected at your dealer.

The DIC display is in the center of
the instrument cluster. The displays
show the status of many vehicle
systems. There are three parts to
the DIC display:
1. DIC menu items and warning lights and messages (includes
operation related information,
diesel particulate filter (DPF)
status, maintenance data, and
errors) 2. Automatic transmission shift
indicator
3. Diesel Exhaust Fluid (DEF) gauge
{Warning
Warning or indicator lights
indicated on the DIC can be
temporarily cleared (for
60 seconds) by pressing the DIC
selector once. However, if the
warning light you have cleared is
an engine overheat warning or
other critical circumstance, never
continue driving without taking the
necessary actions. Otherwise,
you will be in danger of vehicle
breakdown or accident. Should
any of the critical warning lights
come on, immediately contact the
nearest dealer.
