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 430).

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 430). 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.
