9-16 Driving and Operating
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 the Vehicle Is Stuck
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” later in this section.
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).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑68.

above the door latch post. The
Tire and Loading Information
label shows the number of
occupant seating positions (A),
and the maximum vehicle
capacity weight (B) in kilograms
and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (C) and the recommended
cold tire inflation pressures (D).
For more information on tires
and inflation seeTires on
page 10‑48 andTire Pressure
on page 10‑54.
There is also important
information on the Certification/
Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating (GAWR) for the front and
rear axles. See
“Certification/
Tire 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, the 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.

mountain roads, but then you would
also want to use the brakes off
and on.
1 (First):This position reduces
vehicle speed even more than
2 (Second) without using the brakes.
You can use it on very steep hills,
or in deep snow or mud. If the shift
lever is put in 1 (First) while the
vehicle is moving forward, the
transmission will not shift into
first gear until the vehicle is going
slowly enough.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.Manual Transmission
This is your shift pattern.
Here is how to operate the manual
transmission:
1 (First): Press the clutch pedal
and shift into 1 (First). Then, slowly
let up on the clutch pedal as you
slowly press down on the
accelerator pedal. You can shift into 1 (First) when
you are going less than 30 km/h
(20 mph). If you have come to a
complete stop and it is hard to shift
into 1 (First), put the shift lever in
Neutral and let up on the clutch.
Then press the clutch pedal back
down and shift into 1 (First).
2 (Second):
Press the clutch pedal
as you let up on the accelerator
pedal and shift into 2 (Second).
Then, slowly let up on the
clutch pedal as you press the
accelerator pedal.
3 (Third), 4 (Fourth) and 5 (Fifth):
Shift into 3 (Third), 4 (Fourth) and
5 (Fifth) the same way you do for
2 (Second). Slowly let up on the
clutch pedal as you press the
accelerator pedal.
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.

Towing
General Towing
Information
Only use towing equipment that has
been designed for the vehicle.
Contact your dealer or trailering
dealer for assistance with preparing
the vehicle for towing a trailer.
See the following trailer towing
information in this section:
.For information on driving while
towing a trailer, see“Driving
Characteristics and
Towing Tips.”
.For maximum vehicle and trailer
weights, see “Trailer Towing.”
.For information on equipment to
tow a trailer, see “Towing
Equipment.”
For information on towing a disabled
vehicle, see Towing the Vehicle on
page 10‑91. For information on
towing the vehicle behind another vehicle such as a motor home, see
Recreational Vehicle Towing on
page 10‑91.
Driving Characteristics
and Towing Tips
Pulling A Trailer
Here are some important points:
.There are many different laws,
including speed limit restrictions,
having to do with trailering.
Make sure the rig will be legal,
not only where you live but also
where you will be driving.
A good source for this
information can be state or
provincial police.
.Consider using a sway control.
See
“Hitches” inTowing
Equipment on page 9‑63.
.Do not tow a trailer at all during
the first 800 km (500 miles) the
new vehicle is driven. The
engine, axle or other parts could
be damaged.
.Then, during the first 800 km
(500 miles) that a trailer is
towed, do not drive over 80 km/h
(50 mph) and do not make starts
at full throttle. This helps the
engine and other parts of the
vehicle wear in at the heavier
loads.
.Vehicles with automatic
transmissions can tow in
D (Drive), but you may want to
shift to a lower gear selection if
the transmission shifts too often
(e.g., under heavy loads and/or
hilly conditions). If the vehicle
has a manual transmission it is
better not to use the
highest gear.
Three important considerations
have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The weight on the vehicle's tires

Driving with a Trailer
{WARNING
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing
a trailer:
.Have the exhaust system
inspected for leaks and make
necessary repairs before
starting a trip.
.Never drive with the liftgate,
trunk/hatch, or rear-most
window open.(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the Climate Control
system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See Climate
Control System in the Index.
For more information about
Carbon Monoxide, see Engine
Exhaust on page 9‑31.
Towing a trailer requires a certain
amount of experience. Get to know
the rig before setting out for the
open road. Get acquainted with the
feel of handling and braking with the
added weight of the trailer. And
always keep in mind that the vehicle
you are driving is now longer and
not as responsive as the vehicle is
by itself. Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirror adjustments. If the
trailer has electric brakes, start the
vehicle and trailer moving and then
apply the trailer brake controller by
hand to be sure the brakes are
working. This checks the electrical
connection at the same time.
During the trip, check occasionally
to be sure that the load is secure,
and that the lamps and any trailer
brakes are still working.
While towing a trailer or when
exposed to long periods of
sunshine, the floor of the truck bed
may become very warm. Avoid
putting items in the truck bed that
might be affected by high ambient
temperatures.

Total Weight on the
Vehicle's Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification/Tire label
located at the bottom of the center
pillar on the driver's side of the
vehicle, or seeVehicle Load Limits
on page 9‑18. Make sure not to go
over the GVW limit for the vehicle,
or the GAWR, including the weight
of the trailer tongue. If using a
weight distributing hitch, make sure
not to go over the rear axle limit
before applying the weight
distribution spring bars.
Towing Equipment
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch
is needed.
Weight-Distributing Hitches
and Weight Carrying Hitches
A step bumper hitch can be used for
trailers up to 907 kg (2,000 lbs) total
weight, and 90 kg (200 lbs) tongue
weight.
Notice: If a step-bumper hitch is
used, the bumper could be
damaged in sharp turns. Make
sure there is ample room when
turning to avoid contact between
the trailer and the bumper.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. For trailers up to
907 kg (2,000 lbs) safety chains may
be attached to the attaching points
on the bumper. For heavier trailers,
follow the trailer or hitch
manufacturer's recommendation for
attaching safety chains. Always
leave just enough slack so the rig
can turn. Never allow safety chains
to drag on the ground.

Brakes
This vehicle has front disc brakes
and rear drum brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Rear drum brakes do not have
wear indicators, but if a rear brake
rubbing noise is heard, have the
rear brake linings inspected
immediately. Rear brake drums
should be removed and inspected
each time the tires are removed for
rotation or changing. Drum brakes
have an inspection hole to inspect
lining wear during scheduled
maintenance. When the front brake
pads are replaced, have the rear
brakes inspected, too. Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
