Information Display Menu Items
The following display menu items can be displayed by
pressing the information button.
MPH (km/h)
If the vehicle has this display, it shows the vehicle's
speed digitally in either miles per hour (mph) or
kilometers per hour (km/h).
MILES RANGE (km RANGE)
This display shows the approximate number of
remaining miles (mi) or kilometers (km) you can drive
without refilling the fuel tank. This estimate is based
on the current driving conditions and will change if the
driving conditions change. For example, if you are
driving in traffic making frequent stops, the display
may read one number, but if you enter the freeway, the
number may change even though you still have the
same amount of fuel in the fuel tank. This is because
different driving conditions produce different fuel
economies. Generally, freeway driving produces better
fuel economy than city driving.
Once the range drops below about 40 miles (64 km)
remaining, the display will show LOW RANGE.If your vehicle is low on fuel, the Fuel Level Low
message will be displayed. See
“Fuel Level Low”under
DIC Warnings and Messages
on page 4‑76for more
information.
MPG AVG (L/100 km AVG)
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of mpg
(L/100 km) recorded since the last time this display was
reset. To reset MPG AVG, press the reset button. The
display will return to zero.
MPG INST (L/100 km INST)
This display shows the current fuel economy. This
number reflects only the fuel economy that the vehicle
has right now and will change frequently as driving
conditions change. Unlike average fuel economy, this
display cannot be reset.
GAL FUEL USED (L FUEL USED)
This display shows the number of gallons (gal) or
liters (L) of fuel used since the last reset of this display.
To reset GAL FUEL USED, press the reset button. The
display will return to zero.

BATTERY VOLTAGE LOW
This symbol appears
with this message.
This message displays when the electrical system is
charging less than 10 volts or the battery has been
drained.
If this message appears immediately after starting
the engine, it is possible that the generator can still
recharge the battery. The battery should recharge while
driving, but may take a few hours to do so. Consider
using an auxiliary charger to boost the battery after
returning home or to a final destination. Follow the
manufacturer's instructions.
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
to determine the cause of this problem.
To help the generator recharge the battery quickly,
reduce the load on the electrical system by turning
off the accessories. The normal battery voltage range is 11.5 to 15.5 volts.
To monitor battery voltage on the DIC, press the
information button until BATTERY VOLTS displays.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs
to be changed. See your dealer. See
Engine Oilon
page 6‑16and Scheduled Maintenanceon page 7‑3for more information.
After resetting the CHANGE ENGINE OIL SOON
message by clearing it from the display, reset the
engine oil life system separately. For more information
on resetting the engine oil life system, see Engine Oil
Life System on page 6‑20.
CHECK BRAKE FLUID
This message displays if the ignition is on to inform the
driver that the brake fluid level is low. Have the brake
system serviced by your dealer as soon as possible.
See Brake System Warning Light
on page 4‑58for
more information.
CHECK GAS CAP
This message displays when the fuel cap has not been
fully tightened. Recheck the fuel cap to ensure that it is
on and tightened properly.

ENGINE PROTECTION REDUCED
RPM'S (Revolutions Per Minute)
This message displays when your vehicle is in an
overheated engine operating mode. If this message
appears, the vehicle has determined that continued
operation at the existing engine speed may lead to
engine overheating. The vehicle automatically limits
engine RPMs to prevent engine overheating. You may
notice the vehicle upshifting early or reduced speeds
while this message is displayed. When the engine oil
returns to a safe operating temperature, this message
clears from the DIC and the vehicle returns to normal
operation. Your vehicle does not require service when
this message is displayed.
FUEL LEVEL LOW
This symbol appears
with this message.
This message displays and a chime sounds if the fuel
level is low. Refuel as soon as possible. See Fuel
Gauge
on page 4‑68and Fuelon page 6‑6for more
information.

and to the sides.

often.

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator pedal
slightly so the engine runs faster than the idle speed.
This keeps the battery charged to restart the vehicle
and to signal for help with the headlamps. Do this as
little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5‑23.If the vehicle has a traction system, it can often help
to free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the vehicle's tires spin at high speed, they
can explode, and you or others could be injured.
The vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑74.
