.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{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.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.
If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. SeeTr a c t i o nControl/Electronic StabilityControl0190.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forth
between R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,seeTo w i n g t h e V e h i c l e0286.
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 may
show how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification/Tire 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
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.

Tire and Loading InformationLabel
Label Example
AvehiclespecificTireand
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation seeTires0252
andTire Pressure0260.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/Tire Label”later in
this section.
“Steps for Determining CorrectLoad Limit–
1.Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.

6.If your vehicle will be towing
atrailer,loadfromyour
trailer will be transferred to
your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”
SeeTr a i l e r To w i n g0205forimportant information on towing atrailer, towing safety rules andtrailering tips.Example 1
1. Vehicle Capacity Weight forExample 1 = 453 kg(1,000 lbs)
2. Subtract Occupant Weight@68kg(150lbs)◊2=136 kg (300 lbs)
3. Available Occupant andCargo Weight = 317 kg(700 lbs)
Example 2
A. Vehicle Capacity Weight forExample 2 = 453 kg (1,000 lbs)
B. Subtract Occupant Weight @68 kg (150 lbs)◊5 = 136 kg(750 lbs)
C. Available Cargo Weight =11 3 k g ( 2 5 0 l b s )

Example 3
1. Maximum Vehicle CapacityWeight for Example 3 =453 kg (1,000 lbs)
2. Subtract Occupant Weight@91kg(200lbs)◊5=453 kg (1,000 lbs)
3. Available Cargo Weight =0kg (0lbs)
Refer to the vehicle tire and
loading information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined
weight of the driver, passengers,
and cargo should never exceed
the vehicle capacity weight.
Certification/Tire Label
AvehiclespecificCertification/
Tire label is attached to the
center pillar (B-pillar). The label
may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
may show the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, you need to go to a weigh
station and weigh the vehicle.
Yo u r d e a l e r c a n h e l p y o u w i t h
this. Be sure to spread out the
load equally on both sides of the
centerline.
{Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. Try to
spread the weight evenly.
