2013 JEEP GRAND CHEROKEE towing

CAUTION!
Do not use sling type equipment when towing.
When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Without The Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the key fob is with
a flatbed truck. Proper towing equipment is necessary to
prevent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) under the following conditions:
•The transmission must be in NEUTRAL.
•The towing speed must not exceed 30 mph (48 km/h).
•The towing distance must not exceed 15 miles (24 km)
for 6-speed transmission, or 30 miles (48 km) for
8-speed transmission.
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
15 miles (24 km), for 6-speed transmission, or 30 miles
(48 km) for 8-speed transmission, tow with the rear wheels
OFFthe ground. Acceptable methods are to tow the vehicle
on a flatbed, or with the front wheels raised and the rear
wheels on a towing dolly, or (when using a suitable
steering wheel stabilizer to hold the front wheels in the
straight position) with the rear wheels raised and the front
wheels on the ground.

WHAT TO DO IN EMERGENCIES 603

CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Dam-
age from improper towing is not covered under the
New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer
case is operable, vehicleswith a two-speed transfer case
may be towed (in the forward direction, withALLwheels
on the ground),IFthe transfer case is in NEUTRAL and
the transmission is inPARK. Refer to “Recreational
Towing” in “Starting And Operating” for detailed in-
structions.Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and thereforemustbe towed
with all four wheelsOFFthe ground.
CAUTION!
•Front or rear wheel lifts must not be used. Internal
damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when
towing.
•Towing this vehicle in violation of the above re-
quirements can cause severe transmission and/or
transfer case damage. Damage from improper tow-
ing is not covered under the New Vehicle Limited
Warranty.
604 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions tests
can be performed.
•If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the EVIC telltale display area.
Refer to “Electronic Vehicle Information Center (EVIC) in7
MAINTAINING YOUR VEHICLE 609

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
