Engine Coolant Temperature
Management (If Equipped)
WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine could temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep slope in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message could appear in the
information display.
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, slope 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 could 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 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 until
it is at normal operating temperature
(approximately
20 mi (30 km)). 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 turned off for about 30 minutes
to allow fluid to cool to normal operating
temperature 196°F - 215°F (91°C - 102°C)
before checking.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes.

High fluid level
Fluid levels above the safe range may
result in transmission failure. An overfill
condition of transmission fluid may cause
shift and/or engagement concerns and/or
possible damage. High fluid levels can be
caused by an overheating condition.
Adjusting automatic transmission
fluid levels
Note:
Use of a non-approved automatic
transmission fluid may cause internal
transmission damage. Before adding any
fluid, make sure the correct type is used. The
type of fluid used is normally indicated on
the transmission dipstick and also in the
See Capacities and Specifications (page
152). Add fluid in ½ pint (250 ml) increments
through the filler tube until the level is
correct.
Note:
If an overfill occurs, excess fluid
should be removed by an authorized dealer.
An overfill condition of transmission fluid
may cause shift and/or engagement
concerns and/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.
Automatic transmission fluid filter
The TorqShift6â„¢ automatic transmission
is equipped with a serviceable transmission
fluid filter located inside the transmission
bottom pan. Refer to the scheduled
maintenance information for service
intervals for the automatic transmission
fluid and transmission filter. For
transmission filter maintenance, see your
authorized dealer.
BRAKE FLUID CHECK
WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir. WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death.
