2010 JEEP GRAND CHEROKEE ignition

- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control (ETC) system.
• If a problem is detected, the light will come on while the engine is running. Cycle theignition key when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized dealer for service as soon as possible. If the light is flashing
when the engine is running, immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine stall and your vehicle may
require towing.
- Airbag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, we recommendyou drive to the nearest Service Center and have the system serviced as soon as
possible.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as Check Gascap) appears, tighten the gas cap until a“clicking” sound is heard.
• If the message continues to appear for more than three days after tightening the gas cap, see your authorized dealer.
Oil Change Indicator
Message
• If an “oil change” message (shown as Oil Change Required) appears and a single chimesounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating by takingthe 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.

WHAT TO DO IN EMERGENCIES

Jack Location
• The scissor-type jack and tire changing tools are located in the passenger sidecompartment, behind the second row seat.
Spare Tire Stowage
• To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut whichis located under a plastic cover under the cargo load floor, just inside the liftgate opening.
• Lower the spare tire by turning the drive nut counterclockwise with the jack-handle assembly until the spare tire is on the ground with enough cable slack to allow you to
pull the spare tire out from underneath the vehicle.
• When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel.
Preparations For Jacking
• Park on a firm, level surface. Avoid ice or slippery areas.
• Set the parking brake and shift the automatic transmission into PARK.
• Turn the ignition to LOCK and turn on the Hazard Warning flasher.

WARNING!
• 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 seriously 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.
• Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• If using a another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.
