2014 JEEP GRAND CHEROKEE SRT Owners Manual

•Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for proper
inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Tips
NOTE: To provide optimum towing performance and to
protect transmission components always select Trailer
Tow mode when towing a trailer. Before setting out on a
trip, practice turning, stopping and backing the trailer in
an area away from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, select TOW mode, or use
the Paddle Shift switches to manually select a lower gear.
NOTE: Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
TOW Mode
To reduce the potential for automatic transmission over-
heating, select TOW mode when driving in hilly areas, or
select a lower gear (using the Paddle Shift switches) on
more severe grades.

STARTING AND OPERATING 479

Paddle Shift Mode
•When using the Paddle Shift switches, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed. •
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

RECREATIONAL TOWING
(BEHIND MOTORHOME, ETC.)
Recreational towing is not allowed.
CAUTION!
Towing this vehicle with any of its wheels on the
ground can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
NOTE: This vehicle may be towed on a flatbed or
vehicle trailer provided all four wheels are OFFthe
ground.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use, the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
•
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the 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.
484 WHAT TO DO IN EMERGENCIES

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.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

WHAT TO DO IN EMERGENCIES 485

Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.
