.Allow greater following distance 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.
.Turn on Weather Mode. SeeDriver Mode
Control 0208.
Cold Weather Mode
In very low temperatures, a cold weather
message may display on the Driver
Information Center (DIC). The engine speed,
transmission shift patterns, and cabin fan
speed may operate differently to enable the
vehicle to warm up quicker. You can
manually override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 322. 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.
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
.Open a window about 5 cm (2 in) on
the vehicle side 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
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See “Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0194. To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running the engine, push the accelerator
pedal slightly so the engine runs faster than
the idle speed. This keeps the battery
charged to restart the vehicle and to signal
for help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to
free the vehicle when stuck in sand, mud,
ice, or snow.
If stuck too severely for the traction system
to free the vehicle, turn the traction system
off and use the rocking method. See
Traction Control/Electronic Stability Control

206.
{Warning
If the vehicle's tires spin at high speed,
they can explode, and you or others
could be injured. The vehicle can

Warning (Continued)
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 and right to
clear the area around the front wheels. Turn
off any traction system. Shift back and forth
between R (Reverse) and a low forward gear,
spinning the wheels as little as possible. To
prevent transmission wear, wait until the
wheels stop spinning before shifting gears.
Release the accelerator pedal while shifting,
and press lightly on the accelerator pedal
when the transmission is in gear. Slowly
spinning the wheels in the forward and
reverse directions causes a rocking motion
that could free the vehicle. If that does not
get the vehicle out after a few tries, it may
need to be towed out. If the vehicle does
need to be towed out, seeTransporting a
Disabled Vehicle 0293.
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 may properly 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 reduce stopping
performance, damage the tires, and
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). This 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

{Warning
Things you put inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
.Put things in the rear area of your
vehicle. Try to spread the weight
evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in your vehicle.
.When you carry something inside
the vehicle, secure it whenever
you can.
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of driving
this vehicle. Parts have a break-in period and
performance will be better in the long run. During the first 800 km (500 mi), engine
torque will be limited in low gears.
For the first 322 km (200 mi):
.To break in new tires, drive at moderate
speeds and avoid hard cornering.
.New brake linings also need a break-in
period. Avoid making hard stops. This is
recommended every time brake linings
are replaced.
For the first 800 km (500 mi):
.Avoid full throttle starts and abrupt stops.
.Do not exceed 4000 rpm.
.Avoid driving at any one constant speed,
fast or slow, including the use of cruise
control.
.Avoid downshifting to brake or slow the
vehicle when the engine speed will
exceed 4000 rpm.
.Do not let the engine labor. Never lug the
engine. This rule applies at all times, not
just during the break-in period.
For the first 2 414 km (1,500 mi):
.Do not participate in track events, sport
driving schools, or similar activities.
.Check engine oil with every refueling and
add if necessary. Oil and fuel
consumption may be higher than normal.
Front Air Dam (and Splitter)
If equipped, the front air dam and splitter
have minimal ground clearance.
Under normal operation, the components
will occasionally contact some road surfaces
(speed bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a scraping
noise. This is normal and does not indicate a
problem.
Use care when approaching bumps or
objects on road surfaces and avoid them
when possible.
If equipped, the Front Lift System may be
used to increase front air dam or splitter
clearance. See Front Lift System 0214.
Composite Materials
This vehicle may be equipped with parts
containing carbon fiber, sheet-molding
compound, or other composite materials.
Dealer-installed accessories may also contain
composite materials. These parts and
accessories may include the splitter or rocker
extensions.

{Warning
Things that can burn could touch hot
exhaust parts under the vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
Active Fuel Management
This vehicle's engine may be equipped with
Active Fuel Management, which allows the
engine to operate on either all or half of its
cylinders, depending on the driving
conditions.
When less power is required, such as
cruising at a constant vehicle speed, the
system will operate in the half cylinder
mode, allowing the vehicle to achieve better
fuel economy. When greater power
demands are required, such as accelerating
from a stop, passing, or merging onto a
highway, the system will maintain
full-cylinder operation.If the vehicle has an Active Fuel
Management indicator, see Driver
