To check the engine oil level consistently
and accurately, do the following:
1.
Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road. You can
continue to drive your vehicle.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
6F35 Transmission
(If Equipped)
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
properly working. For example, if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
See
Scheduled Maintenance (page 475).
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.
6F55 Transmission
(If Equipped) WARNING:
The dipstick and
surrounding components are hot. Use
gloves when moving components and
checking the transmission fluid level.
Failure to follow this warning could result
in serious personal injury.

Note:
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle approximately 20 mi
(30 km) until it is warmed up. If your vehicle
has been operated for an extended period
at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle
should be switched off until normal operating
temperatures are reached to allow the fluid
to cool before checking. Depending on
vehicle use, cooling times could take up to
30 minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
1. Drive the vehicle
20 mi (30 km) or until it
reaches normal operating temperature
2. Park the vehicle on a level surface and engage the parking brake. 3.
With the parking brake engaged and your
foot on the brake pedal, start the engine
and move the gearshift lever through all
of the gear ranges. Allow a minimum of
10 seconds for each gear to engage.
4. Put the gearshift lever in park (P) and leave the engine running.
Note: You will need to move the air filter
assembly to access the transmission
dipstick.
5. Remove the dipstick, wiping it clean with
a clean, dry lint free rag. If necessary,
refer to 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 by turning it to
the locked position.
7. Remove the dipstick and inspect the fluid
level. The fluid should be in the
designated areas for normal operating
temperature. Moving the Air Filter Assembly (Accessing
the Dipstick) WARNING:
Do not start the engine
with the air filter removed. This can cause
damage not covered by the vehicle
Warranty and can result in serious injury. 1. Shut the engine off.
2. Clean the area around the clamps that
connect the air filter assembly to the
rubber hoses (A).

High fluid level
If the fluid level is above the MAX range of
the dipstick, remove fluid to reach the
hashmark level.
Note:
Fluid level above the MAX level may
cause shift or engagement concerns or
possible damage. High fluid levels can be
caused by an overheating condition. If your
vehicle has been operated for an extended
period at high speeds, in city traffic during
hot weather or pulling a trailer, the vehicle
should be switched off until normal operating
temperatures are reached. Depending on
vehicle use, cooling times could take up to
30 minutes or longer. Adjusting Automatic Transmission Fluid
Levels
Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on the dipstick and also
in the Technical Specifications section in this
chapter.Note:
An overfill condition of transmission
fluid may cause shift or engagement
concerns or possible damage.
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.
Reinstall the air filter assembly. After the fluid
level has been checked and adjusted as
necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees
clockwise without disconnecting the
sensor.
4. Seat the air filter assembly back into the
grommets by pushing down on the air
filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attach air filter assembly to the front of the
vehicle.
7. Install the bolt cover (if equipped).
