Buick Enclave: Engine Overheating. Overheated Engine Protection Operating Mode. Power Steering Fluid
The vehicle has several indicators to warn of engine overheating. There is an engine coolant temperature gauge on the instrument panel cluster. See Engine Coolant Temperature Gauge . The vehicle may also display an ENGINE OVERHEATED IDLE ENGINE and ENGINE OVERHEATED
STOP ENGINE message in the Driver Information Center (DIC). See Engine Cooling System
Messages . You may decide not to lift the hood when this warning appears, but instead get
service help right away. See Roadside Assistance Program (U.S. and Canada) or Roadside Assistance
Program (Mexico) . If you do decide to lift the hood, make sure the vehicle is parked on a level
surface. Then check to see if the engine cooling fans are running. If the engine is overheating,
both fans should be running. If they are not, do not continue to run the engine
and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered
by the warranty. Notice: If the engine catches fire while driving with no coolant, the vehicle
can be badly damaged. The costly repairs would not be covered by the vehicle warranty. See Overheated
Engine Protection Operating Mode for information on driving to a safe place
in an emergency. If Steam Is Coming from the Engine Compartment Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when the vehicles engine is overheated, the liquids in
it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get
out of the vehicle until the engine is cool. See Overheated Engine Protection Operating Mode for information on driving
to a safe place in an emergency. If No Steam Is Coming from the Engine Compartment If an engine overheat warning is displayed but no steam can be seen or heard,
the problem may not be too serious. Sometimes the engine can get a little too hot
when the vehicle: 1. Turn the air conditioning off. If the temperature overheat gauge is no longer in the overheat zone or an overheat
warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle
distance from the car in front of you. If the warning does not come back on, continue
to drive normally. If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for three minutes while parked.
If the warning is still displayed, turn off the engine until it cools down. Also,
see “Overheated Engine Protection Operating Mode” next in this section. This emergency operating mode lets the vehicle be driven to a safe place in an
emergency situation. If an overheated engine condition exists, an overheat protection
mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is a significant loss in power and engine performance. The
temperature gauge indicates an overheat condition exists. Driving extended distances
and/or towing a trailer in the overheat protection mode should be avoided. Notice: After driving in the overheated engine protection operating mode,
to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change
the oil and reset the oil life system. See Engine Oil . The power steering fluid reservoir is located under the engine cover on the passenger
side of the vehicle. See Engine Compartment Overview for reservoir location. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect
there is a leak in the system or you hear an unusual noise. A fluid loss in this
system could indicate a problem. Have the system inspected and repaired. How to Check Power Steering Fluid To check the power steering fluid: 1. Turn the key off and let the engine compartment cool down. See Engine Cover . The fluid level should be somewhere between the MAX and MIN line on the dipstick
in room temperature. If the fluid is on or below the MIN line, add fluid close to
the MAX Line. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants
. Always use the proper fluid. Notice: Use of the incorrect fluid may damage the vehicle and the damages
may not be covered by the vehicle's warranty. Always use the correct fluid listed
in Recommended Fluids and Lubricants .Engine Overheating
WARNING
Steam from an overheated engine can burn you badly, even if you just open the
hood. Stay away from the engine if you see or hear steam coming from it. Turn it
off and get everyone away from the vehicle until it cools down.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open
the windows as necessary.
3. If in a traffic jam, shift to N (Neutral); otherwise, shift to the highest gear
while driving—D (Drive) or L (Low).Overheated Engine Protection Operating Mode

2. Remove the engine cover.
3. Wipe the cap and the top of the reservoir clean.
4. Unscrew the cap and wipe the dipstick with a clean rag.
5. Replace the cap and completely tighten it.
6. Remove the cap again and look at the fluid level on the dipstick.
