transmission uid leak is the only
reason for uid loss. If a leak occurs,
take your vehicle to a dealer/retailer
and have it repaired as soon as
possible.
Change the uid and lter at the
intervals listed in the Maintenance
Schedule. SeeScheduled
Maintenance on page 11-4. Be sure

coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, if you add
only DEX-COOL
®extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see
Engine Overheating on page 9-16.A 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant will:
Give freezing protection down
to−34°F (−37°C).
Give boiling protection up to
265°F (129°C).
Protect against rust and
corrosion.
Help keep the proper engine
temperature.
Let the warning lights and gages
work as they should.
Notice:Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the rst maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.

Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a
battery has ller caps, be sure
the right amount of uid is
there. If it is low, add water to
take care of that rst. If you
don’t, explosive gas could be
present.

Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle
may need a different turn signal
asher and/or extra wiring. Check
with your dealer/retailer. The arrows
on your instrument panel will
ash whenever you signal a turn or
lane change. Properly hooked
up, the trailer lamps will also ash,
telling other drivers you are
about to turn, change lanes or stop.
When towing a trailer, the arrows
on your instrument panel will
ash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers behind you are
seeing your signal when they
are not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning
lights. When you plug a trailer
lighting system into your vehicle’s
lighting system, its bulb warning
lights may not let you know if one of
your lamps goes out. So, whenyou have a trailer lighting system
plugged in, be sure to check
your vehicle and trailer lamps from
time to time to be sure they are
all working. Once you disconnect the
trailer lamps, the bulb warning
lights again can tell you if one of
your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower
gearbeforeyou start down a
long or steep downgrade. If you do
not shift down, you might have
to use your brakes so much
that they would get hot and no
longer work well.
On a long uphill grade, shift down to
a lower gear and reduce your
speed to around 45 mph (70 km/h)
to reduce the possibility of engine
and transmission overheating.
Parking on Hills
{CAUTION
You really should not park your
vehicle, with a trailer attached,
on a hill. If something goes
wrong, your rig could start to
move. People can be injured,
and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig
on a hill, here is how to do it:
1. Apply your regular brakes, but do
not shift into P (Park) yet.
2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in
place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the regular brakes.
Then apply your parking
brake, and then shift to P (Park).
5. Release the regular brakes.
