If the burnout is not completed in
15 seconds, torque will be reduced to
idle, the parking brake will be applied,
Line Lock releases, and Custom
Launch Control will be disabled.
Ensure the parking brake is
disengaged to re-enter Launch
Control.
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.

DRIVING AND OPERATING 225
{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.
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.
Caution
Driving through deep puddles or
standing water can cause water to
come in through the engine air
intake and damage the engine.(Continued)
Caution (Continued)
If deep puddles or standing water
cannot be avoided, proceed with
caution and do not exceed 8 km/h
(5 mph). Do not drive through
water that may come close to or
cover the vehicle’s underbody.
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.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment
in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper tread
depth. SeeTires0363.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, and cooling system.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.

226 DRIVING AND OPERATING
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering assist.
Always have the engine running
and the vehicle in gear.
.Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the center line.
.Be alert on top of hills; something
could be in your lane (e.g., stalled
car, crash).
.Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the wheels and
brake components, always clear
snow and ice from inside the
wheels and underneath the vehicle
before driving.
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For slippery road driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
.Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0257.
.Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should be
applied sooner than when on dry
pavement. See Antilock Brake System
(ABS) 0253.
See Driver Mode Control 0258.
.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.
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 Service. See Roadside
Service 0432. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside mirror.

DRIVING AND OPERATING 227
{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 0241. 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 0257.
{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 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

might need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle (Electronic Shifter)
0393 or
Towing the Vehicle (Mechanical Shifter)
0 395.
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
(Continued)
Warning (Continued)
(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 vehicle's 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 tire size of
the original equipment tires (3)
and the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
see Tires 0363 and
Tire Pressure 0370.
There is also important loading
information on the Certification
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 Label” later
in this section.

“Steps for Determining Correct
Load 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 a
trailer, load from your 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.”
See Trailer Towing (LSY 2.0L L4
Engine) 0318 for important
information on towing a trailer,
towing safety rules, and
trailering tips.
Example 1
1.Vehicle Capacity Weight for
Example 1 = 453 kg
(1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 2 = 136 kg
(300 lbs).
3.Available Occupant and Cargo
Weight = 317 kg (700 lbs).

Example 2
1.Vehicle Capacity Weight for
Example 2 = 453 kg
(1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 5 = 340 kg
(750 lbs).
3.Available Cargo Weight =
113 kg (250 lbs).
Example 3
1.Vehicle Capacity Weight for
Example 3 = 453 kg
(1,000 lbs).
2.Subtract Occupant Weight @
91 kg (200 lbs) × 5 = 453 kg
(1,000 lbs).
3.Available Cargo Weight =
0 kg (0 lbs).
Refer to the vehicle's 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's capacity weight.
Certification Label
Label Example
A vehicle-specific Certification
label is attached to the vehicle's
center pillar (B-pillar). The label
may show the gross weight
capacity of the vehicle, called the
Gross Vehicle Weight Rating
(GVWR). The GVWR includes the
weight of the vehicle, all
occupants, fuel, and cargo.

{Warning
Things 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. In the cargo
area, put them as far forward
as possible. 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 the vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.
Starting and Operating
New Vehicle Break-In
Caution
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.
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4000 engine rpm.
.Avoid driving at any one
constant speed, fast or slow.
.Do not drive above
129 km/h (80 mph).
.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 in high gear
at low speeds. With a manual
transmission, shift to the next (Continued)
Caution (Continued)
lower gear. This rule applies at all
times, not just during the
break-in period.
.Do not participate in racing
events, sport driving schools,
or similar activities during this
break-in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
322 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
.New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.(Continued)
