Engine Fluid Temperature

Management (If Equipped)

WARNING

To reduce the risk of collision and

injury, be prepared that the vehicle

speed may reduce and the vehicle

may not be able to accelerate with full

power until the fluid temperatures reduce.

The design of your vehicle makes it

possible to pull a trailer, but because of

the added load, the vehicle’s engine may

temporarily reach higher temperatures

during severe operating conditions such as

ascending a long or steep grade while

pulling a trailer in hot ambient

temperatures.

At this time, you may notice your engine

coolant temperature gauge needle move

toward the H and the POWER REDUCED

TO LOWER TEMP message may appear

in the information display.

You may notice a reduction in vehicle

speed caused by reduced engine power.

The design of your vehicle allows it to enter

this mode if certain high-temperature and

high-load conditions take place in order to

manage the engine fluid temperatures. The

amount of speed reduction will depend on

the vehicle loading, towing, grade, ambient

temperature and other factors. If this

occurs, there is no need to pull off the road.

You can continue to drive your vehicle

while this message is active.

The air conditioning may also cycle on and

off during severe operating conditions to

protect overheating of the engine. When

the engine coolant temperature decreases

to a more normal operating temperature,

the air conditioning will turn on once again.

If you notice any of the following:

• 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 How

Fail-Safe Cooling Works for

additional information.

AUTOMATIC TRANSMISSION

FLUID CHECK

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.
