1-2 In Brief
Automatic Transfer Case
The transfer case knob is located to
the left of the instrument panel
cluster. You can choose among
five driving settings:
2
m(Two-Wheel Drive High):This
setting is used for driving in most
street and highway situations.
AUTO (Automatic Four-Wheel
Drive): This setting is ideal for use
when road surface traction
conditions are variable. 4
m(Four-Wheel Drive High):
Use
the four-wheel high position when
you need extra traction, such as on
snowy or icy roads or in most
off-road situations.
4
n(Four-Wheel Drive Low) : This
setting delivers extra torque. You
might choose Four-Wheel Drive Low
if you are driving off-road in deep
sand, deep mud, deep snow, and
while climbing or descending steep
hills.
N (Neutral): Shift the vehicle's
transfer case to N (Neutral) only
when towing the vehicle. See
Recreational Vehicle Towing on
page 10‑36 and“Towing the
Vehicle” in the owner manual.
See Four-Wheel Drive on
page 9‑10.
Hybrid Features
High Voltage Safety
Information
This vehicle has a standard 12-volt
battery and a high voltage hybrid
battery. Only a trained service
technician with the proper
knowledge and tools should inspect,
test, or replace the hybrid battery.
See your dealer if the hybrid battery
needs service.
The 12-volt battery cables, in the
engine compartment, are clearly
labeled. In emergency situations,
first responders can cut those
cables to disable the high voltage
hybrid battery system.

gear—not in N (Neutral). If you
are pulling a trailer, see “Driving
Characteristics and Towing Tips”
in the owner manual.
1. Hold the brake pedal down, then set the parking brake.
See “Parking Brake” in the
owner manual.
2. Move the shift lever into the P (Park) position by pulling the
shift lever toward you and
moving it up as far as it will go.
3. Be sure the transfer case (if equipped) is in a drive
gear —not in N (Neutral).
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set.
If you have four-wheel drive and
the transfer case is in N (Neutral),
the vehicle will be free to roll,
even if the shift lever is in
P (Park). So be sure the transfer
case is in a drive gear —not in
N (Neutral).
And, if you leave the vehicle with
the engine running, it could
overheat and even catch fire. You
or others could be injured. Do not
leave the vehicle with the engine
running unless you have to. If you have to leave the vehicle with
the engine running, be sure your
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you move the shift
lever into P (Park), hold the regular
brake pedal down. Then, see if you
can move the shift lever away from
P (Park) without first pulling it toward
you. If you can, it means that the
shift lever was not fully locked into
P (Park).
Torque Lock
If parking on a hill and the
transmission not shifted into
P (Park) properly, the weight of
the vehicle may put too much
force on the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, see
Shifting
Into Park on page 9‑4.

Automatic Transfer Case
The transfer case knob is located to
the left of the instrument panel
cluster.
Use this dial to shift into and out of
four-wheel drive.
You can choose among five driving
settings:
Indicator lights in the switches show
you which setting you are in. The
indicator lights will come on briefly
when you turn on the ignition and
the last chosen setting will stay on.If the lights do not come on, you
should take the vehicle to your
dealer for service. An indicator light
will flash while shifting. It will stay on
when the shift is completed. If for
some reason the transfer case
cannot make a requested shift, it will
return to the last chosen setting.
2
m(Two-Wheel Drive High):
This
setting is used for driving in most
street and highway situations. The
front axle is not engaged in
two-wheel drive. This setting also
provides the best fuel economy.
AUTO (Automatic Four-Wheel
Drive): This setting is ideal for use
when road surface traction
conditions are variable. When
driving your vehicle in AUTO, the
front axle is engaged, but the
vehicle's power is primarily sent to
the rear wheels. When the vehicle's
software determines a need for
more traction, the system will
transfer more power to the front wheels. Driving in this mode results
in slightly lower fuel economy than
Two-Wheel Drive High.
4
m(Four-Wheel Drive High):
Use
the four-wheel high position when
you need extra traction, such as on
snowy or icy roads or in most
off-road situations. This setting also
engages the front axle to help drive
the vehicle. This is the best setting
to use when plowing snow.
4
n(Four-Wheel Drive Low) : This
setting also engages the front axle
and delivers extra torque. You may
never need this setting. It sends
maximum power to all four wheels.
You might choose Four-Wheel Drive
Low if you are driving off-road in
deep sand, deep mud, deep snow,
and while climbing or descending
steep hills.

10-22 Vehicle Care
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See“Vehicle Load Limits”
in the owner manual for an
example of the label and its
location on your vehicle.
The Tire Pressure Monitor
System (TPMS) sensors will
need to be reset after a tire
rotation. See “TPMS Sensor
Identification Codes” under“Tire
Pressure Monitor Operation”.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
“Capacities and Specifications ”
in the owner manual.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause you to
lose control of the vehicle and
you or others may be injured in a
crash. Use another type of
traction device only if its
manufacturer recommends it for
use on the vehicle and tire size
combination and road conditions.
Follow that manufacturer's
instructions. To help avoid
(Continued)
WARNING (Continued)
damage to the vehicle, drive
slowly, re‐adjust or remove the
device if it is contacting the
vehicle, and do not spin the
wheels. If you do find traction
devices that will fit, install them on
the rear tires.
If a Tire Goes Flat
Your vehicle has a tire inflator kit.
There is no spare tire, no tire
changing equipment, and no place
to store a tire.
It is unusual for a tire to blow out
while you are driving, especially if
you maintain your tires properly.
If air goes out of a tire, it is much
more likely to leak out slowly. But,
if you should ever have a blow out,
here are a few tips about what to
expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
