2010 JEEP GRAND CHEROKEE User Guide

- 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.
47
WHAT TO DO IN EMERGENCIES

• 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. Havethe 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.
JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the
jack or changing the wheel.
• Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a
vehicle that is on a jack. If you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a
firm, level surface only. Avoid ice or slippery areas.
• If it is necessary to retrieve the spare tire from under the vehicle on the side of the vehicle close to moving traffic, pull far enough off the road to avoid the danger of
being hit.
Run Flat Tires - SRT8 Only
• If your vehicle is equipped with Run Flat Tires, it is not equipped with a jack or spare tire.
• Although the tires are designed with a “run flat” feature that allows the vehicle to be
driven about 50 miles (80 km) at 55 mph (88 km/h), immediate service should be
obtained.

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.
49
WHAT TO DO IN EMERGENCIES

• Block both the front and rear of the wheeldiagonally opposite of the jacking position.
For example, if changing the right front tire,
block the left rear wheel.
NOTE: Passengers should not remain in the
vehicle when the vehicle is being jacked.
Jacking And Tire Changing Instructions
WARNING!
Carefully follow these tire changing procedures to help prevent personal injury or
damage to your vehicle: Always park on a firm, level surface as far from the edge of
the roadway as possible before raising the vehicle.
• Remove the spare tire, jack and tools from their stored location.
• Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground.
• Assemble the jack and jacking tools. Connect the jack handle driver to the extension, then to the lug wrench.
• Place the jack: • For front wheels, place it under the front lower control arm.

• For rear wheels, place it under the axle near the wheel to be changed.
51
WHAT TO DO IN EMERGENCIES

• Turn the jack screw clockwise to firmly engage the jack saddle with the lift area of thesill flange.
• Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire.
WARNING!
Raising the vehicle higher than necessary can make the vehicle less stable and
cause an accident. It could slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
• Remove the lug nuts, wheel cover (if equipped) and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Do NOT attempt to install a center cap or wheel cover on the
compact spare. Lightly tighten the lug nuts clockwise. To avoid the risk of forcing the
vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered.
• Lower the vehicle by turning the jack screw to the left, and remove the jack and wheel blocks.
• Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each one has been tightened twice. The correct wheel nut
tightness is 95 ft lbs (130 N•m). If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or at a service station.
WARNING!
A loose tire or jack, thrown forward in a collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack parts and the spare tire in the places
provided.
• Secure the tire, jack, and tools in their proper locations.
NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down may
result in scratching or damage to the wheel face. Continue winching up the tire until you
hear the winch “ratchet” three times.

JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using a set of jumpercables and a battery in another vehicle or by using a portable battery booster pack.
• Jump-starting can be dangerous if done improperly so please follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack follow the manufacturer’s operating
instructions and precautions.
CAUTION!
Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
When temperatures are below the freezing point, electrolyte in a discharged battery
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.
53
WHAT TO DO IN EMERGENCIES

Preparations for Jump-Start
• The battery in your vehicle is located in the front of the engine compartment, behind theleft headlight assembly.
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.
WARNING!
Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in personal injury or property damage
due to battery explosion.
• Connect the positive (+)end of the jumper cable to the positive (+)post of the discharged
