• the engine coolant temperature gauge
moves fully into the red (hot) area
• the coolant temperature warning light
illuminates
• the service engine soon indicator
illuminates.
WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
1. Pull off the road as soon as safely
possible and place the vehicle in P
(Park).
2. Leave the engine running until the
coolant temperature gauge needle
moves away from the H range. After
several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, you may
restart your engine and continue on.
5. If the coolant is low, add coolant,
restart the engine and take your vehicle
to an authorized dealer. See Adding
engine coolant in this chapter for more
information. Refer to fail-safe cooling
for additional information.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check and
change the transmission fluid and filter at
the correct service interval. See
Scheduled Maintenance (page 428).
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
Checking Automatic Transmission
Fluid (If Equipped)
For scheduled intervals of the fluid checks
and changes, See Scheduled
Maintenance (page 428). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
i.e., if the transmission slips or shifts slowly
or if you notice some sign of fluid leakage.
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is at normal
operating temperature (approximately
19 mi (30 km)). Verify that the
transmission fluid temperature gauge,
located on the instrument cluster, is within
normal range.
1. Drive the vehicle 19 mi (30 km)until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and
engage the parking brake.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Latch the gearshift lever in P and leave
the engine running.
5. Remove the dipstick, wiping it clean
with a clean, dry lint free rag. If
necessary, refer to the Under Hood
Overview in this chapter for the
location of the dipstick.
6. Install the dipstick making sure it is fully
seated in the filler tube.
7. Remove the dipstick and inspect the
fluid level. The fluid should be in the
designated area for normal operating
temperature or ambient temperature.
