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
StabiliTrak
®Systemon page 5‑6improves the
ability to accelerate on slippery roads, but slow down
and adjust your driving to the road conditions. When
driving through deep snow, turn off the traction control
part of the StabiliTrak
®System to help maintain vehicle
motion at lower speeds.
The Antilock Brake System (ABS)
on page 5‑4improves 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, if equipped, on slippery surfaces.
5-25

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
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, now and then
when you run 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 Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5‑28.If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{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
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑89.
5-27

Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. For four-wheel-drive vehicles,
shift into Four‐Wheel High. For vehicles with
StabiliTrak
®, turn the traction control part of the system
off. Shift back and forth between R (Reverse) and a
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. Recovery hooks can be used, if the
vehicle has them. If the vehicle does need to be towed
out, see Towing Your Vehicle on page 5‑44.
Recovery Hooks
{WARNING:
These hooks, when used, are under a lot of force.
Always pull the vehicle straight out. Never pull on
the hooks at a sideways angle. The hooks could
break off and you or others could be injured from
the chain or cable snapping back.
5-28

{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 cargo 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.
.Do not leave a seat folded down unless
you need to.
There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving“ underOff-Road
Driving
on page 5‑11.
Two-Tiered Loading
Depending on the model of your pick‐up, you can
create an upper load platform by positioning two
or four 2 inches (5 cm) by 6 inches (15 cm)
wooden planks across the width of the pickup box.
The planks must be inserted in the pickup box
depressions. The length of the planks must allow
for at least a 3/4 inch (2 cm) bearing surface on
each end of the plank.
When using this upper load platform, be sure the
load is securely tied down to prevent it from
shifting. The load's center of gravity should be
positioned in a zone over the rear axle. The zone
is located in the area between the front of each
wheel well and the rear of each wheel well. The
center of gravity height must not extend above the
top of the pickup box flareboard.
Any load that extends beyond the vehicle's
taillamp area must be properly marked according
to local laws and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
5-35

In order to calculate the amount of weight any front
accessory, such as a snow plow, is adding to the front
axle, use the following formula:
(W x (A + W.B.)) /W.B.= Weight the accessory is adding
to the front axle.Where:
W = Weight of added accessory
A = Distance that the accessory is in front of the
front axle
W.B. = Vehicle Wheelbase
For example, adding a 318 kg (700 lb) snow plow
actually adds more than 318 kg (700 lbs) to the front
axle. Using the formula, if the snow plow is 122 cm (4 ft)
in front of the front axle and the wheel base is 305 cm
(10 ft), then:
W = 318 kg (700 lb)
A = 122 cm (4 ft)
W.B. = 305 cm (10 ft)
(W x (A + W.B.))/W.B. = (700 x (4 + 10))/10 = 445 kg
(980 lbs)
So, if the front axle reserve capacity is more than
445 kg (980 lbs), you could add the snow plow without
exceeding the front GAWR.
5-39

Here is an example of proper truck and camper
match:
A.Camper Center of Gravity
B.Recommended Center of Gravity
Location Zone
When the truck is used to carry a slide‐in camper,
the total cargo load of the truck consists of the
manufacturer's camper weight figure, the weight of
installed additional camper equipment not
included in the manufacturer's camper weight
figure, the weight of camper cargo, and the weight
of passengers in the camper. The total cargo load
should not exceed the truck's cargo weight rating and the camper's center of gravity (A) should fall
within the truck's recommended center of gravity
zone (B) when installed.
You must weigh any accessories or other
equipment that you add to your vehicle. Then,
subtract this extra weight from the CWR. This
extra weight may shorten the center of gravity
zone of your vehicle. Your dealer can help you
with this.
If your slide-in camper and its load weighs less
than the CWR, the center of gravity zone for your
vehicle may be larger.
Your dealer can help you make a good
vehicle-camper match and help you determine
the CWR.
After you have loaded your vehicle and camper,
drive to a weigh station and weigh the front and
rear wheels separately. This will tell you the loads
on the axles. The loads on the front and rear
axles should not be more than either of the Gross
Axle Weight Ratings (GAWR). The total of the
axle loads should not be more than the Gross
Vehicle Weight Rating (GVWR).
5-42

Open the driver's door and look at the
Certification/Tire label to find out your vehicle's
GAWRs and GVWR.
If your vehicle has gone over the weight ratings,
move or take out some things until all the weight
falls below the ratings.
Secure loose items to prevent weight shifts that
could affect the balance of your vehicle. When the
truck‐camper is loaded, drive to a scale and weigh
on the front and on the rear wheels separately to
determine axle loads. Individual axle loads should
not exceed either of the gross axle weight ratings
(GAWR). The total axle loads should not exceed
your vehicle's gross vehicle weight rating
(GVWR). These ratings are given on the vehicle
certification label attached to the rear edge of the
driver's door. See“Certification/Tire Label” under
Loading the Vehicle
on page 5‑29. If weight
ratings are exceeded, move or remove items to
bring all weights below the ratings. When you install and load your slide-in camper,
check the manufacturer's instructions.
If you want more information on curb weights,
cargo weights, Cargo Weight Rating and the
correct center of gravity zone for your vehicle,
your dealer can help you. Just ask for a copy of
“Consumer Information, Truck-Camper Loading.”
Pickup Conversion to Chassis Cab
We are aware that some vehicle owners might consider
having the pickup box removed and a commercial or
recreational body installed. Owners should be aware
that, as manufactured, there are differences between a
chassis cab and a pickup with the box removed which
could affect vehicle safety. The components necessary
to adapt a pickup to permit its safe use with a
specialized body should be installed by the body
builder.

Towing
Towing Your Vehicle
To avoid damage, the disabled vehicle should be towed
with all four wheels off the ground. Consult your dealer
or a professional towing service if the disabled vehicle
must be towed. SeeRoadside Assistance Program
on
page 8‑7.
To tow the vehicle behind another vehicle for
recreational purposes, such as behind a motorhome,
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
If the vehicle has a two–mode hybrid engine, see the
Two–mode Hybrid manual for more information.
Recreational vehicle towing means towing the vehicle
behind another vehicle–such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a
device known as a dolly. Here are some important things to consider before
recreational vehicle towing:
.What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer's
recommendations.
.What is the distance that will be travelled? Some
vehicles have restrictions on how far and how long
they can tow.
.Is the proper towing equipment going to be used?
See your dealer or trailering professional for
additional advice and equipment
recommendations.
.Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. See
Before Leaving on a
Long Trip on page 5‑23.

Dinghy Towing
Two-Wheel-Drive Vehicles
Notice:If the vehicle is towed with all four wheels
on the ground, the drivetrain components could be
damaged. The repairs would not be covered by the
vehicle warranty. Do not tow the vehicle with all four
wheels on the ground.
Two-wheel-drive vehicles should not be towed with all
four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
Four-Wheel-Drive Vehicles
Use the following procedure to dinghy tow a
four-wheel-drive vehicle:
1. Position the vehicle being towed behind the tow vehicle and shift the transmission to P (Park).
5-45

2. Turn the engine off and firmly set the parkingbrake.
3. Securely attach the vehicle being towed to the tow vehicle.
{WARNING:
Shifting a four-wheel-drive vehicle's transfer case
into N (Neutral) can cause the vehicle to roll even
if the transmission is in P (Park). The driver or
others could be injured. Make sure the parking
brake is firmly set before the transfer case is
shifted to N (Neutral). 4. Shift the transfer case to N (Neutral). See
“Shifting
into Neutral” underFour-Wheel Drive
on
page 3‑36for the proper procedure to select the
Neutral position for the vehicle.
5. Release the parking brake only after the vehicle being towed is firmly attached to the towing
vehicle.
6. Turn the ignition to LOCK/OFF and remove the key —the steering wheel will still turn.
After towing, see “Shifting Out of Neutral” under
Four-Wheel Drive
on page 3‑36for the proper
procedure to take the vehicle out of the Neutral position.
