2011 JEEP GRAND CHEROKEE cooling

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the
radiator and aids in removing heat from the engine cooling system.
• If the temperature reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam
from your radiator. If you see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool. Never try to open a cooling
system pressure cap when the radiator or coolant bottle is hot.

WARNING!
• When temperatures are below the freezing point, electrolyte in a dischargedbattery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above freezing point before attempting a jump-start.
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can start anytime the ignition switch is on. You can be injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make an inadvertent electrical contact. You could be severely injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage due to battery explosion.
• Do not connect the cable to the negative post (-)of the discharged battery. The
resulting electrical spark could cause the battery to explode and could result in
personal injury.
EMERGENCY TOW HOOKS
• If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to
minimize the risk of damage to the vehicle.
CAUTION!
Tow hooks are for emergency use only, to rescue a vehicle stranded off-road. Do
not use tow hooks for tow truck hookup or highway towing. You could damage
your vehicle. Tow straps are recommended when towing the vehicle; chains may
cause vehicle damage.
WARNING!
• Chains are not recommended for freeing a stuck vehicle. Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become disengaged, causing serious injury.
