To Deactivate
A soft tap on the brake pedal, pulling the speed control
lever toward you “CANCEL”, normal braking, or clutch
pressure while slowing the vehicle, will deactivate speed
control without erasing the set speed memory. Pressing
the ON/OFF button or turning off the ignition switch
erases the set speed memory.
To Resume Speed
To resume a previously set speed, push the RESUME
ACCEL lever up and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Vary The Speed Setting
When the speed control is ON, speed can be increased by
pushing up and holding RESUME ACCEL. Release the
lever when the desired speed is reached, and the new
speed will be set.Tapping RESUME ACCEL once will result in a 1 mph (1.6
km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (4.8 km/h), etc.
To decrease speed while speed control is ON, push down
and hold SET DECEL. Release the lever when the desired
speed is reached, and the new speed will be set.
Tapping the SET DECEL button once will result in a 1
mph (1.6 km/h) speed decrease. Each time the button is
tapped, speed decreases.
Manual Transaxle
Depressing the clutch pedal will disengage the speed
control. A slight increase in engine RPM before the speed
control disengages is normal.
Vehicles equipped with manual transaxles may need to
be shifted into a lower gear to climb hills without speed
loss.

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Program (ESP)” in this Section of this
manual.
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 vehicles speed
are sufficient to potentially cause wheel lift, it applies the
brake of the appropriate wheel and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It can not
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.

HDC has the capability to sense terrain and will only
activate when the vehicle is descending a hill. It will not
activate on level ground. If desired, HDC can be fully
deactivated by putting the vehicle into ESP “Full Off”
mode. This is done by pressing and holding the ESP OFF
button for five seconds. Refer to “Electronic Stability
Program (ESP)” in this section of the manual.
HDC operation can be overridden with brake application
to slow the vehicle down below the HDC control speed.
Conversely, if more speed is desired during HDC control,
the accelerator pedal will increase vehicle speed like
normal. When either the brake or the accelerator is
released, HDC will control the vehicle back to the origi-
nal set speed.
HDC is only intended for low speed off-road driving. At
vehicle speeds above 31 mph (50 km/h) HDC will no
longer function. If the HDC indicator light begins to flashthis indicates that the brakes are getting too hot and the
vehicle should be stopped to allow the brakes to cool.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESP uses sensors in the

ESP Operating Modes
The ESP system has three available operating modes for
4WD equipped vehicles and two available operating
modes for 2WD equipped vehicles.
Full On (4WD Models) or On (2WD Models)
This is the normal operating mode for ESP. Whenever the
vehicle is started the ESP system will be in this “On”
mode. This mode should be used for most driving
situations. ESP should only be turned to “Partial Off” or
“ESP Off” for specific reasons as noted below.
Partial Off (4WD Models) or On (2WD Models)
This mode is entered by momentarily depressing the ESP
OFF switch. When in “Partial Off” mode the “ESP
Indicator Light” will be illuminated. This mode is in-
tended to be used if the vehicle is in deep snow, sand or
gravel conditions and more wheel spin than ESP would
normally allow is required to gain traction.To turn ESP on again, momentarily depress the ESP OFF
switch. This will restore the normal “ESP On” mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
Full Off (4WD Models Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ESP OFF switch for five
seconds when the vehicle is stopped and the engine is
running. After five seconds, the “ESP Indicator Light”

ESP/BAS Warning Light and ESP Indicator Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow “ESP/BAS Warning Light”
and the yellow “ESP Indicator Light” in the instrument
cluster both come on when the ignition switch is turned
to the ON position. They should both go out with the
engine running. If the “ESP/BAS Warning Light” comes
on continuously with the engine running, a malfunction
has been detected in either the ESP or BAS system, or
both. 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), see your
authorized dealer as soon as possible to have the problem
diagnosed and corrected.NOTE:•The “ESP Indicator Light” and the “ESP/BAS Warning
Light” come onmomentarilyeach time the ignition
switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
GARAGE DOOR OPENER — IF EQUIPPED
HomeLinkreplaces up to three remote controls (hand-
held transmitters) that operate devices such as garage
door openers, motorized gates, lighting, or home security
systems. The HomeLinkunit operates off your vehicle’s
battery.

Electrical Outlet Use With Engine Off
CAUTION!
•Many accessories that can be plugged in 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 engine starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.); will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.
Power Outlet — 115 Volts (150 Watts)

Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer (if equipped) is shared. It is located
in the front of the engine compartment on the passenger
side and should be checked for fluid level at regular
intervals. Fill the reservoir with windshield washer sol-
vent (not radiator antifreeze) and operate the system for
a few seconds to flush out the residual water.
Rear Window Defroster
The pushbutton is located on
the bottom right side of the
blower control knob. Press
this button to turn on the rear
window defroster. An amber
light shows that the defroster
is on.The defroster will automatically turn off after approxi-
mately ten minutes. For an additional five minutes of
operation, press the button again. To prevent excessive
battery drain, use the defroster only when the engine is
operating.
