Instruments and Controls 5-7
English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure should be 200 to
550 kPa (29 to 80 psi). In certain
situations, such as long extended
idles on hot days, it could read as
low as 105 kPa (15 psi) and still be
considered normal. A reading in the low pressure zone
may be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check the
oil as soon as possible.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
AUTO STOP
When the engine goes into
Automatic Engine Stop, the oil
pressure gauge drops to zero when
the tachometer is at the AUTO
STOP position. This is normal and
oil pressure returns to the normal
operating range once the engine
starts.
See Starting the Vehicle on
page 9‑2 for more information.
AUTO STOP displays in the Driver
Information Center (DIC) when the
vehicle speed is zero. See Driver
Information Center (DIC) on
page 5‑11 for more information.

{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil

This light comes on briefly as a
check it works, when the ignition is
in ON/RUN. If it does not, have the
vehicle serviced.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
During an AUTO STOP there is zero
oil pressure, but this light will not
come on.

BATTERY VOLTAGE
This display shows the current
battery voltage. If the voltage is in
the normal range, the value will
display. For example, the display
may read BATTERY VOLTAGE
13 VOLTS. Your vehicle's charging
system regulates voltage based on
the state of the battery. The battery
voltage may fluctuate when viewing
this information on the DIC. This is
normal. See “Charging System
Light” in the owner manual for more
information. If there is a problem
with the battery charging system,

Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to check
the transmission fluid level. The
only reason for fluid loss is a
transmission leak or overheating the
transmission. If a small leak is
suspected, then use the following
checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer service department and have
it repaired before driving the vehicle
further.
Notice:Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑1. Change the fluid and filter at the
scheduled maintenance intervals
listed in Scheduled Maintenance.
Be sure to use the transmission fluid
listed in
Recommended Fluids and
Lubricants on page 11‑1.How to Check Automatic
Transmission Fluid
Notice: Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Before checking the fluid level,
prepare the vehicle as follows:
1. Start the engine and park the
vehicle on a level surface. Keep
the engine running.
2. Apply the parking brake and place the shift lever in P (Park). 3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, move the
shift lever back to P (Park).
4. Allow the engine to idle (500–800 RPM) for at least
one minute. Slowly release the
brake pedal.
5. Keep the engine running and press the Trip/Fuel button or
trip odometer reset stem until
TRANS TEMP (Transmission
Temperature) displays on the
Driver Information Center (DIC).
6. Using the TRANS TEMP reading, determine and perform
the appropriate check
procedure. If the TRANS TEMP
reading is not within the required
temperature ranges, allow the
vehicle to cool, or operate the
vehicle until the appropriate
transmission fluid temperature is
reached.
