ignition JEEP GRAND CHEROKEE 2012 WK2 / 4.G Owner's Manual

• The power outlets are labeled with either a “key” or a “battery” symbolto indicate how the outlet is powered. Power outlets labeled with a “key”
are powered when the ignition switch is in the ON/RUN or ACC position,
while the outlets labeled with a “battery” are connected directly to the
battery and powered at all times.
NOTE:
• Do not exceed the maximum power of 160 Watts (13 Amps) at 12 Volts. If the 160 Watt (13 Amp) power rating is exceeded, the fuse protecting the
system will need to be replaced.
• Power outlets are designed for accessory plugs only. Do not insert any other object in the power outlet as this will damage the outlet and blow
the fuse. Improper use of the power outlet can cause damage not covered
by your new vehicle warranty.
• The rear cargo power outlet can be switched to “battery” powered all the time by switching the power outlet right rear quarter panel fuse in the fuse
panel.

Shifting Procedures
4WD HI To 4WD LOW• With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON/RUN position or the engine running, shift the
transmission into NEUTRAL, and press the “4WD LOW” button once on
the transfer case switch. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and remain on solid when the shift
is complete.
4WD LOW To 4WD HI • With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON/RUN position or the engine running, shift the
transmission into NEUTRAL, and press the “4WD LOW” button once on
the transfer case switch. The “4WD LOW” indicator light in the
instrument cluster will flash and turn off when the shift is complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor temperature protection exists, a “For 4x4 Low Slow Below 5 MPH or 8 KPH
Put Trans in N Press 4 Low” message will flash on the Electronic Vehicle
Information Center (EVIC).
• Shifting into or out of 4WD LOW is possible with the vehicle completely stopped; however, d ifficulty may occur due to the mating clutch teeth not
being properly aligned. Several attempts may be required for clutch teeth
alignment and shift completion to occur. The preferred method is with the
vehicle rolling 0 to 3 mph (0 to 5 km/h). If the vehicle is moving faster than
3 mph (5 km/h), the transfer case will not allow the shift.
NEUTRAL Shift Procedure
• Turn the ignition switch to the ON/RUN position, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL.
• Press and hold the NEUTRAL button located near the 4WD mode control knob with a pen or similar object for four seconds. The indicator light will
begin to flash indicating the shift is in progress. The light will stop
blinking (stay on solid) when the NEUTRAL shift is complete. A “4WD
SYSTEM IN NEUTRAL” message will display on the Electronic Vehicle
Information Center (EVIC).
• Repeat these Steps to shift out of NEUTRAL.

• 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.
