Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle's electrical
system and affect your vehicle
warranty.
Additional Towing EquipmentMany states, Canadian provinces and
territories require special outside
mirrors when towing a trailer. Even if
they don't, you should install special
mirrors if you cannot clearly see
behind you, or if the trailer creates a
blind spot.
Ask your trailer sales or rental
agency if any other items are
recommended or required for your
towing situation.Pre-Tow Checklist
When preparing to tow, and before
driving away, be sure to check the
following:
●The vehicle has been properly
serviced, and the suspension,
cooling system, and lights are in
good operating condition.

●The trailer has been properly
serviced and is in good condition.●All weights and loads are within
limits.●The hitch, safety chains, and any
other attachments are secure.●All items in or on the trailer are
properly secured and cannot shift
while you drive.
●The lights and brakes on your
vehicle and the trailer are working
properly.●Your vehicle tires and spare are
properly inflated, and the trailer
tires and spare are inflated as
recommended by the trailer
maker.Driving Safely With a Trailer
The added weight, length, and
height of a trailer will affect your
vehicle's handling and performance,
so driving with a trailer requires
some special driving skills and
techniques.
For your safety and the safety of
others, take time to practice driving
maneuvers before heading for the
open road, and follow the guidelines
in this section.

Towing Speeds and GearsDrive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D position when towing a
trailer on level roads. See‘‘
Driving on
Hills
’’ in the next column for
additional gear information. Do not
exceed 55 mph (88 km/h). At higher
speeds, the trailer may sway or affect
vehicle handling. When driving uphill and downhill,
use the S position (without using the
paddle shifters) to provide the proper
engine power and engine braking on
each gear. You can also use the
paddle shifters. In this case, select
third, second, or first gear with the
paddle shifter; depending on the
vehicle speeds and road condition.
Do not use fourth and fifth gears.
The recommended speed range for
each gear position is shown in the
table.
Gear position Speed range 10 -38 mph
(0 - 60 km/h)
2, 3 19 -62 mph
(30 -100 km/h)
Making Turns and BrakingMake turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and
distance for braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknife or turn over.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge (see page
78). If it nears the H (Hot) mark, turn
the A/C off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
When driving down hills, reduce
your speed, and shift down to S
position, or use the paddle shifters to
the lower gear (3, 2 or 1)in the S
position. When towing a trailer, do
not‘‘ride ’’the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
Handling Crosswinds and BuffetingCrosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel; then turn the wheel to the left
to get the trailer to move to the left,
and turn the wheel right to move the
trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires.Towing Your VehicleYour vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page 475.

ꭧ 2fluid
Driving in mountainous areas at very low vehicle speeds
or trailer towing results in higher transmission and
transfer temperatures. This requires transmission and
transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed at 60,000
miles (100,000 km), then every 30,000 miles (48,000 km).

Driving in mountainous areas at very low vehicle speeds
or trailer towing results in higher level of mechanical

Check the condition of the wiper
blades at least every six months.
Replace them if you find signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.
To replace a front wiper blade:
1. Raise each wiper arm off thewindshield, lifting the driver's side
first, then the passenger's side.Do not open the hood when the wiper
arms are raised, or you will damage the
hood and the wiper arms.
2. Disconnect the blade assemblyfrom the wiper arm:
●Press and hold the lock tab.●Slide the blade assembly toward
the lock tab until it releases
from the wiper arm.
When replacing a wiper blade,
make sure not to drop the wiper
blade or wiper arm down on the
windshield.

Check the condition of the battery
monthly by looking at the test
indicator window. The label on the
battery explains the test indicator's
colors.Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent future
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (- ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.

●Block the rear wheels.●If the vehicle is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.●Leave one window open slightly (if
the vehicle is being stored
indoors).●Disconnect the battery.●Support the front and rear wiper
blade arms with a folded towel or
rag so they do not touch the
windshield.●To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehicle body wax to the painted
surfaces that mate with the door
and tailgate seals.
●Cover the vehicle with a
‘‘breathable ’’cover, one made from
a porous material such as cotton.
Non-porous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.●If possible, periodically run the
engine until it reaches full
operating temperature (the cooling
fans cycle on and off twice).
Preferably, do this once a month. Interior Care
Leather
Vacuum dirt and dust from the
leather frequently. Pay close
attention to the pleats and seams.
Clean the leather with a soft cloth
dampened with a 90% water and 10%
neutral wool detergent solution.
Then buff it with a clean, dry cloth.
Remove any dust or dirt on leather
surfaces immediately.
