Driving and Operating 9-9
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving
to these conditions. It is important
to slow down on slippery surfaces
because stopping distance is longer
and vehicle control more limited.
While driving on a surface with
reduced traction, try to avoid
sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You might
not realize the surface is slippery
until the vehicle is skidding. Learn
to recognize warning clues—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
Remember: Antilock brakes help
avoid only the braking skid.Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in
a quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
(Continued)
WARNING (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road
is wet enough and you are going
fast enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.

Driving and Operating 9-11
WARNING (Continued)
to slow the vehicle enough to
maintain speed and control.
You could crash. Always have
the vehicle running and in gear
(preferably LOW range) when
going downhill. This will allow
the electric drive unit to assist in
slowing and maintaining speed.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in
your own lane.
.Top of hills: Be
alert—something could
be in your lane (stalled car,
accident).
.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.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from
around the base of the
vehicle, especially any that
is blocking the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from
the wind to bring in fresh air.
.Fully open the air outlets
on or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control Systems
in the Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑30.
To conserve energy, run the
vehicle for only short periods as
needed to warm the vehicle and
then shut the vehicle off and close
the window most of the way to
save heat. Repeat this until help
arrives but only when you feel really
uncomfortable from the cold. Moving
about to keep warm also helps.
If it takes some time for help to
arrive, start the vehicle. The engine
may start to charge the 12‐volt
battery. Turn off unnecessary
accessories to conserve energy.

Vehicle Load Limits
It is very important to know
how much weight the vehicle
can carry. This weight is called
the vehicle capacity weight
and includes the weight of
all occupants, cargo, and all
nonfactory‐installed options.
Two labels on the vehicle
show how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification label.{WARNING
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle. Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). With the driver door
open, the label is attached
below the door lock post.

The Remote Keyless Entry (RKE)
transmitter must be in the vehicle.
Press the brake pedal and push
and release the POWER
Obutton.
If the RKE transmitter is not in the
vehicle or something is interfering
with the transmitter, a message
displays in the Driver Information
Center (DIC). See Key and Lock
Messages on page 5‑48.
If the vehicle will not start due
to a low RKE transmitter battery,
the vehicle can still be driven.
See “Starting the Vehicle with
a Low Transmitter Battery” in
Remote Keyless Entry (RKE)
System Operation on page 2‑3.
A Welcome, Ready, and Good‐bye
audio message will be heard in
the vehicle and animated on the
instrument cluster when opening
the driver door upon entry, when
the vehicle is ready to be driven,
and when the vehicle is turned off. The instrument cluster displays an
active fuel or battery gauge, along
with an audio startup cue, when
the vehicle is ready to be driven.
This could take up to 15 seconds
at extremely cold temperatures.
The engine will only start if needed.
If the vehicle did not start, the
instrument cluster will display
a screen with inactive fuel and
battery gauges. See
Starting and
Stopping the Vehicle on page 9‑20.

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).
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.
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 Jump Starting on page 10‑79.

9-30 Driving and Operating
When FMM is needed, the FMM
Request screen appears on the
center stack display at vehicle start.
If Yes is selected, FMM will begin.
FMM will automatically continue at
each vehicle start until fresh fuel is
added.
If No is selected, the FMM Request
screen will appear when the vehicle
is next started. The FMM request
can be delayed for only one day.If the FMM request was delayed for
one day, FMM will start at the next
vehicle start and display the FMM
Notification screen on the center
stack display.
If FMM is required and the fuel level
is low, FMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. See
Propulsion Power
Messages on page 5‑50.
Engine Exhaust
{WARNING
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The engine is running in
Extended Range Mode in
areas with poor ventilation
(parking garages, tunnels,
or deep snow that may block
underbody airflow or tail
pipes).
.The exhaust smells or
sounds strange or different.
.The exhaust system leaks
due to corrosion or damage.
.The vehicle exhaust system
has been modified, damaged,
or improperly repaired.

9-32 Driving and Operating
Electric Drive Unit
The vehicle uses an electric drive
unit. The shift lever is on the
console between the seats.
P (Park):This position locks the
front wheels. It is the best position
to use when starting the propulsion
system because the vehicle cannot
move easily.
{WARNING
It is 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.
Do not leave the vehicle when
the propulsion system is running
unless you have to. If you have
left the propulsion system
running, 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, always set the
parking brake and move the shift
lever to P (Park). See Shifting Into
Park on page 9‑22.
Make sure the shift lever is fully
in P (Park) before starting the
propulsion system. The vehicle
has an electric drive unit shift lock
control system. The regular brake must be fully applied first and then
the shift lever button pressed before
shifting from P (Park) when the
vehicle is in ON/RUN. If you cannot
shift out of P (Park), ease pressure
on the shift lever, then push the shift
lever all the way into P (Park) as
you maintain brake application.
Then press the shift lever button
and move the shift lever into
another gear. See
Shifting out
of Park on page 9‑23.
R (Reverse): Use this gear to
back up.
Notice: Shifting to R (Reverse)
while the vehicle is moving
forward could damage the electric
drive unit. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse)
only after the vehicle is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the electric drive unit, see
If the Vehicle Is Stuck on page 9‑13.
