Driving Information
Steering
This vehicle has On-Demand
Electric-Assist Power Steering
instead of conventional full-time
hydraulic power steering. It uses
electricity supplied by the same
battery which is re-charged by the
regenerative braking system.
Because the system is On-Demand
Electric-Assist, energy is used only
when the steering wheel is turned,
or when the steering gear is used to
help isolate the forces of rough
roads. This system does not use
power steering fluid, making it
maintenance-free.

9-10 Driving and Operating
When you move the shift lever into
M, the transmission will default to
M4. In this gear range, effective
engine braking occurs at speeds
above 72 km/h (45 mph).
Pushing the minus (−) button on the
shift lever reduces the gear range.
In the M3 gear range, effective
engine braking occurs at speeds
above 56 km/h (35 mph).
In the M2 gear range, effective
engine braking occurs at speeds
above 40 km/h (25 mph).
In the M1 gear range, effective
engine braking occurs at speeds
above 16 km/h (10 mph).
When operating in M (Manual
Mode), Auto Stop is disabled. For
better vehicle efficiency, operate the
vehicle in D (Drive) not
M (Manual Mode).
Cruise control can be used while
using the Range Selection Mode.Drive Systems
Four-Wheel Drive
If the vehicle has four-wheel drive,
you can send the engine's driving
power to all four wheels for extra
traction. Read the following before
using four-wheel drive.
Notice:Driving on clean, dry
pavement in Four-Wheel Drive
High or Four-Wheel Drive Low for
an extended period of time may
cause premature wear on the
vehicle's powertrain. Do not drive
on clean, dry pavement in
Four-Wheel Drive High or
Four-Wheel Drive Low for
extended periods of time. While driving on clean dry pavement
and during tight turns, you may
experience a vibration in the
steering system.
The vehicle has StabiliTrak. Shifting
into Four-Wheel Drive Low will turn
Traction Control and StabiliTrak off.
See
“StabiliTrak System” in the
owner manual.
Front Axle
The front axle engages and
disengages automatically when you
shift the transfer case. Some delay
for the axle to engage or disengage
is normal.

5. Add the pre‐mixed DEX‐COOL,available at your dealer, until the
coolant level is maintained at the
FULL COLD mark. This should
take no longer than two minutes
of hybrid cooling pump
operation.
If the level cannot be kept at the
FULL COLD level, the vehicle
may need service. See your
dealer.
6. Then replace the DMCM coolant
surge tank pressure cap. Be
sure the pressure cap is
hand-tight and fully seated. Notice:
Using tap water, cooling
system sealers or conditioners in
an attempt to stop coolant leaks
can damage the DMCM and
engine cooling systems. Never
use tap water, cooling system
sealers or conditioners in your
cooling system.
Power Steering Fluid
The vehicle has electric power
steering and does not use power
steering fluid.
Battery
This vehicle has a standard 12‐volt
battery and a high voltage hybrid
battery.
Refer to the replacement number on
the original battery label when a
new standard 12‐volt battery is
needed. 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
dealer has information on how to
recycle the hybrid battery. There
is also information available at
http://www.recyclemybattery.com.
If an airbag inflates or the vehicle
has been in a crash, the vehicle's
sensing system might command the
automatic hybrid battery disconnect
to open. See
Replacing Airbag
System Parts After a Crash on
page 3‑2 for more information.
{DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.

the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blow out, particularly on a
curve, acts much like a skid and
may require the same correction
you would use in a skid. In any rear
blow out, remove your foot from the
accelerator pedal. Get the vehicle
under control by steering the way
you want the vehicle to go. It may
be very bumpy and noisy, but you
can still steer. Gently brake to a
stop, well off the road, if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has
been driven on while severely
under-inflated or flat may cause a
blowout and a serious crash.(Continued)
WARNING (Continued)
Never attempt to re-inflate a tire
that has been driven on while
severely under-inflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place and stopping, well
off the road, if possible. Then
do this:
1. Turn on the hazard warning flashers.
2. Park your vehicle. Set the parking brake firmly and put the
shift lever in PARK (P).
3. Turn off the engine.
4. Inspect the flat tire. If the tire has been separated from
the wheel or has damaged sidewalls
or large tears that allow rapid air
loss, call a tire repair facility. See
“Roadside Assistance Program”
in
the owner manual.
If the flat tire is due to a slow leak
caused by a nail or other similar
road hazard, the tire inflator kit may
be used to repair the damaged tire
temporarily. The kit uses a liquid tire
sealant to seal small punctures in
the tread area of the tire.
After repairing a tire with the tire
inflator kit, take your vehicle to an
authorized dealer to have the tire
inspected and repaired as soon as
possible. The tire sealant is a
temporary repair only. See Tire
Sealant and Compressor Kit on
page 10‑24.

Dinghy Towing
Two-Wheel Drive Vehicles
Notice:If the vehicle is towed
with all four wheels on the
ground, the drivetrain
components could be damaged.
The repairs would not be covered
by the vehicle warranty. Do not
tow the vehicle with all four
wheels on the ground.
Two-wheel drive vehicles should not
be towed with all four wheels on the
ground. Two-wheel drive transmissions have no provisions
for internal lubrication while being
towed.
Four-Wheel Drive Vehicles
Use the following procedure to
dinghy tow a four-wheel drive
vehicle:
1. Position the vehicle being towed
behind the tow vehicle and shift
the transmission to P (Park).
2. Turn the engine off and firmly set the parking brake. See “Parking
Brake” in the owner manual. 3. Securely attach the vehicle
being towed to the tow vehicle.
{WARNING
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). The driver or others
could be injured. Make sure the
parking brake is firmly set before
the transfer case is shifted to
N (Neutral).
4. Shift the transfer case to N (Neutral). For more information
on“Shifting into N (Neutral)”, see
“Four Wheel Drive” in the owner
manual.
5. Release the parking brake only after the vehicle being towed is
firmly attached to the towing
vehicle.
6. Turn the ignition to LOCK/OFF and remove the key —the
steering wheel will still turn.
