If the word OFF is lit on the
passenger airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0126 for more information,
including important safety
information.
Charging System Light
The charging system 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.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode. See Ignition
Positions 0186.
This light may also come on when
the system has detected a problem
with the Diesel Exhaust Fluid (DEF)
management system. See Diesel
Exhaust Fluid 0198.

away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off.
SeeFuel (Gasoline) 0236 or
Fuel for Diesel Engines 0238.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
test equipment will likely connect to
the vehicle's Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to service the vehicle may affect
vehicle operation. See
Add-On
Electrical Equipment 0257. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running.
. The light does not come on
when the ignition is in
Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set. The
light stays on if the parking brake
does not fully release. If it stays on
after the parking brake is fully

or in pounds per square inch (psi).
Fuel Filter Life : This display shows
an estimate of the fuel filter's
remaining useful life. If 90% Fuel
Filter Life Remaining is displayed, it
means 90% of the current fuel filter
life remains. The fuel filter life
system will alert when to change the
fuel filter on a schedule consistent
with your driving conditions. When
the remaining fuel filter life is low,
the CHANGE FUEL FILTER
message will appear on the display.
Change the fuel filter as soon as
possible. Diesel Exhaust Fluid (DEF) Level

The DEF
level will be displayed as either OK,
XX%, or LOW. When LOW appears
on the display, add DEF as soon as
possible. See Diesel Exhaust Fluid

the coolant temperature in degrees
Celsius (°C) or degrees
Fahrenheit (°F). TC/Stabilitrak :

Fuel Economy : The center
displays the approximate
instantaneous fuel economy as a
number and bar graph. Displayed
above the bar graph is a running
average of fuel economy for the

graph is the best average fuel
economy that has been achieved for
the selected distance. The selected
distance is displayed at the top of
the page as “last xxx mi/km.” Press
Vto select the distance or reset
best value.
The display provides information on
how current driving behavior affects
the running average and how well
recent driving compares to the best
that has been achieved for the
selected distance.

on the display, add DEF as soon as
possible. See Diesel Exhaust Fluid
0 198.
Oil Pressure : Oil pressure is
displayed in either kilopascal (kPa)
or in pounds per square inch (psi).
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity. On some models, the oil
pump will vary engine oil pressure
according to engine needs. Oil
pressure may change quickly as the
engine speed or load varies. This is
normal. If the oil pressure warning
light or Driver Information Center
(DIC) message indicates oil
pressure outside the normal
operating range, check the vehicle's
oil as soon as possible.
Vehicle Messages

The messages that do not require
immediate action can be
acknowledged and cleared by
pressing
V. The messages that
require immediate action cannot be
cleared until that action is
performed.
All messages should be taken
seriously; clearing the message
does not correct the problem.
If a SERVICE message appears,
see your dealer.

instrument cluster light will come
on to indicate the IntelliBeam
system is reactivated.
. The IntelliBeam system will turn
off if the fog lamps are
turned on.
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.
. The vehicle is being driven on
winding or hilly roads.
The IntelliBeam system may need to
be disabled if any of the above
conditions exist.
Headlamp High/
Low-Beam Changer
Push the turn signal lever away
from you and release, to turn the
high beams on. To return to low
beams, push the lever again or pull

To flash the high beams, pull the
turn signal lever toward you
momentarily and then release it.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to

the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system comes on in
daylight when the following
conditions are met:
. The ignition is on.
. The exterior lamp control is
in AUTO.
. The vehicle is not in P (Park).
. The light sensor determines it is
