warning JEEP GRAND CHEROKEE 2012 WK2 / 4.G Owner's Guide

• Your vehicle has also been equipped with a TPMS malfunction indicatorto indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated. This
sequence will continue each time the vehicle is restarted as long as the
malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C)
of air temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter. Example: If garage temperature is
68°F (20°C) and the outside temperature is 32°F (0°C), then the cold tire
inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and
wheels. TPMS pressures and warning have been established for the
tire size equipped on your vehicle. Undesirable system operation or
sensor damage may result when using replacement equipment that is
not of the same size, type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to the sensors may
result.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the
brake system may have failed. It will take longer to stop the vehicle.
You could have a collision. Have the vehicle checked immediately.

- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality,etc., may illuminate the MIL after engine start. The vehicle should be
serviced if the light stays on through several typical driving cycles. In
most situations, the vehicle will drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic
converter damage. We recommend you do not operate the vehicle. Have
the vehicle serviced immediately.
- Electronic Stability Control (ESC) Activation/MalfunctionIndicator Light
• If the “ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has been detected
in the ESC system. If this light remains on after several ignition cycles,
and the vehicle has been driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), we recommend you drive to the nearest
service center and have the vehicle serviced immediately.
• The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires lose traction and the ESC system becomes active. If the light
begins to flash during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed and driving to
the prevailing road conditions. The light also flashes when TCS is active.
To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESC system to Partial Off mode
by momentarily pressing the ESC Off
switch located below the
climate controls, on the switch panel.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on whiledriving, stop the vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving,we recommend you drive to the nearest service center and have the
vehicle serviced immediately.

- 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 the ignition 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 service center i mmediately. 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.
- Air Bag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have the vehicle serviced by an authorized service center immediately.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as Check Gascap) appears, tighten thegas cap until a “clicking” sound is heard.
• If the message continues to appear for more than three days after tightening the gas cap, have the vehicle serviced by an authorized
service center immediately.

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential foroverheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in 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 blower 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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
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.

3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized
dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that all lug nuts are properly seated against the wheel.
CAUTION!
• Do not attempt to raise the vehicle by jacking on locations otherthan those indicated in the Jacking Instructions for this vehicle.
• Be sure to mount the spare tire with the valve stem facing outward. The vehicle could be damaged if the spare tire is mounted
incorrectly.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close tomoving traffic. Pull far enough off the road to avoid the danger of
being hit when operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never put 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.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used 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.
• Always park on a firm, level surface as far from the edge of the

• Only use the jack in the positions indicated and for lifting thisvehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be stowed with the valve stem facing the ground.
• Carefully follow these tire changing warnings to help prevent personal injury or damage to your vehicle:
• Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the wheel nuts fully until the vehicle has been lowered. Failure to
follow this warning may result in personal injury.
• 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. Have the deflated (flat)
tire repaired or replaced immediately.
BATTERY LOCATION
• The battery in your vehicle is located under the passenger's front seat. Remote battery posts are located on the right side of the engine
compartment for jump-starting.
JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using aset of jumper cables 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.
WHAT TO DO IN EMERGENCIES
108

• If frequent jump-starting is required to start your vehicle you should havethe battery and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other boostersource with a system voltage greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long enough, the
vehicle’s battery will discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in adischarged 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.
• 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.
