2006 DODGE GRAND CARAVAN fuel cap

21. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come when turning the key
from OFF to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs. (See page 399
for more information.) 22. Trac Off Indicator — If Equipped
This display indicator should illuminate for approxi-
mately four seconds as a bulb check when the ignition
switch is first turned ON.
The “ TRAC OFF ” Indicator will flash if the traction
control is in use.
The “ TRAC OFF ” Indicator will illuminate if:
• The Traction Control switch has been used to turn
the system OFF.
• There is a Traction Control System malfunction
• The system has been deactivated to prevent damage
to the brake system due to overheated brake tem-
peratures.
NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC and
the OFF indicators located in the instrument cluster.210 UNDERSTANDING YOUR INSTRUMENT PANEL

This is to prevent overheating of the brake system and is
a normal condition. The system will remain disabled for
about 4 minutes until the brakes have cooled. The system
will automatically reactivate and turn off the TRAC and
the OFF indicators.
If your vehicle becomes stuck in mud, ice, or snow, turn
the Traction Control System OFF before attempting to
“ rock ” the vehicle free.
23. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined. The trip odometer shows individual trip mileage. To
switch from odometer to trip odometer, press the Trip
Odometer button.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged,
GASCAP will be displayed in the instrument cluster
odometer. Tighten the fuel filler cap properly and press
the odometer reset button to turn the GASCAP message
off. If the problem continues, the message will appear the
next time the vehicle is started. See Section 7 of this
manual for more information.

System is ON. UNDERSTANDING YOUR INSTRUMENT PANEL 211

ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door on the left side
of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle. CAUTION!Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
NOTE: The driver ’ s side sliding door cannot be opened
while the fuel door is open. This feature operates only
when the sliding door is fully closed prior to opening the
fuel door.
CAUTION!To avoid fuel spillage and overfilling, do not “ top
off ” the fuel tank after filling has stopped.Fuel Filler Cap (Gas Cap)346 STARTING AND OPERATING

NOTE:
• Tighten the fuel filler cap until you hear a “ clicking ”
sound. This is an indication that the fuel filler cap is
properly tightened. If the vehicle diagnostic system
determines that the fuel filler cap is loose, improperly
installed, or damaged, GASCAP will be displayed in
the instrument cluster odometer. Tighten the fuel filler
cap properly and press the odometer reset button to
turn the GASCAP message off. If the problem contin-
ues, the message will appear the next time the vehicle
is started. See Section 7 of this manual for more
information. Make sure that the fuel filler cap is
tightened each time the vehicle is refueled.
• When the fuel nozzle “ clicks ” or shuts off, the fuel
tank is full. WARNING!• Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling. STARTING AND OPERATING 347

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade) — 2.4 Liter
Engines
SAE 5W-30 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle. For information on engine oil filler cap location, refer to
the Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Engine Oil Viscosity (SAE Grade) — 3.3/3.8 Liter
Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Refer to your engine
oil filler cap for the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
the Engine Compartment illustration in this section.
