9-10 Driving and Operating
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but
apply the brakes sooner than when
on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on slippery
surfaces.
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use the Roadside
Assistance Program. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.

Shifting Into Park
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the propulsion
system on, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow.
1. Hold the brake pedal down and set the parking brake.
See Electric Parking Brake on
page 9‑34 for more information.
2. Move the shift lever into P (Park) by pushing the lever all the way
toward the front of the vehicle.
3. Turn the vehicle off.
Leaving the Vehicle with the
Propulsion System On
{WARNING
It can be dangerous to leave the
vehicle with the propulsion
system on. The vehicle could
move suddenly if the shift lever is
not fully in P (Park) with the
parking brake firmly set. And,
if you leave the vehicle with the
propulsion system on, it could
overheat and even catch fire. You
or others could be injured. Do not
leave the vehicle with the
propulsion system on.
If you have to leave the vehicle with
the propulsion system on, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
down the regular brake pedal. 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
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the electric drive
unit. This happens when parking on
a hill and shifting the electric drive
unit into P (Park) is not done
properly and then it is difficult to
shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park).
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).

Driving and Operating 9-23
Shifting out of Park
To shift out of P (Park), the vehicle
must be in ON/RUN, the brake
pedal must be applied, and the
charge cord must be unplugged.
The vehicle has an electronic shift
lock release system. The shift lock
release is designed to:
.Prevent the vehicle from turning
off unless the shift lever is in
P (Park).
.Prevent moving the shift lever
out of P (Park), unless the
vehicle is in ON/RUN, the brake
pedal is applied, and the charge
cord is unplugged.
Parking the vehicle in extreme cold
for several days without the charge
cord connected may cause the
electric drive unit to be locked in
P (Park) until the propulsion system
has warmed sufficiently.
The shift lock is always functional
except in the case of an uncharged
or low charged 12‐volt battery (less
than 9 volts). If the vehicle has an uncharged 12‐
volt battery or a 12‐volt battery with
low voltage, try charging or jump
starting the 12‐volt battery. See
Battery on page 10‑25
orJump
Starting on page 10‑75.
If the console shift lever cannot be
moved out of P (Park):
1. Apply and maintain the regular
brakes.
2. Turn the vehicle on using the POWERObutton. See Power
Button on page 9‑18.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button.
5. Move the shift lever into the desired gear.
If you still cannot move the shift
lever from P (Park), see your dealer
or a professional towing service.
