2013 JEEP WRANGLER steering wheel

POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system. •
Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end of
the steering wheel travel will increase the steering fluid
temperature and it should be avoided when possible.
Damage to the power steering pump may occur.

STARTING AND OPERATING 455

HSA Off
If you wish to turn off the HSA system, follow this
procedure:
1.
Start with the engine off and vehicle in PARK (automatic
transmission) or NEUTRAL with clutch out (manual
transmission) with wheels straight. Apply parking brake
on manual transmission vehicle.
2. Start the engine.
3. With the engine running, the brake applied, and theclutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESC OFF switch four times within twenty seconds.
5. Rotate the steering wheel 360° clockwise (180° clock- wise from center). 6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESC
Activation/Malfunction Indicator Light” will blink
several times to confirm HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the speed
of the vehicle. When ERM determines that the rate of change
of the steering wheel angle and vehicle’s speed are sufficient
to potentially cause wheel lift, it applies the appropriate
brake and may reduce engine power to lessen the chance
that wheel lift will occur. ERM will only intervene during
very severe or evasive driving maneuvers.
466 STARTING AND OPERATING

Electronic Roll Mitigation (ERM) can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors such as road conditions, leaving the road-
way or striking objects or other vehicles.
NOTE:Anytime the ESC system is in the “Full Off”
mode, ERM is disabled. Refer to Electronic Stability
Control (ESC) for a complete explanation of the available
ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. Electronic Roll
Mitigation (ERM) cannot prevent all wheel lift or

WARNING! (Continued)
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the safety
of others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by apply-
ing the brake of the appropriate wheel to assist in
counteracting the over/under steer condition. Engine
power may also be reduced to help the vehicle maintain
the desired path.
5
STARTING AND OPERATING 467

ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” (located
in the instrument cluster), starts to flash as soon as the tires
lose traction and the ESC system becomes active. The “ESC
Activation/Malfunction Indicator Light” also flashes when
TCS is active. If the “ESC Activation/Malfunction Indicator
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 condi-
tions.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user ’s safety or the safety of
others.
468 STARTING AND OPERATING

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.
(Continued)
WARNING! (Continued)
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size may
result in false speedometer and odometer readings.
498 STARTING AND OPERATING

Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative(-)jumper cable from the
engine ground of the vehicle with the discharged
battery.
7. Disconnect the negative end (-)of the jumper cable
from the negative (-)post of the booster battery.
8. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the booster battery.
9. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.CAUTION!
Accessories 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 without engine operation, the vehicle’s battery
will discharge sufficiently to degrade battery life and/or
prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or 2nd gear and
REVERSE (with manual transmission), while gently press-
ing the accelerator. Use the least amount of accelerator pedal
pressure that will maintain the rocking motion, without
spinning the wheels, or racing the engine.6
