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’s 
how 
to do  it: 
1.  Apply  your regular  brakes,  but  don’t shift into 
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. 
PARK (P) yet. 
4. Reapply the regular brakes.  Then apply  your  parking 
5. Release the regular brakes. 
brake, 
and shift  to 
PARK (P). 
When You Are  Ready to Leave After 
Parking on a Hill 
1. Apply  your regular brakes  and  hold the pedal down 
while  you: 
0 Start your  engine; 
Shift  into  a  gear; and 
Release  the parking brake. 
2. Let  up  on the  brake  pedal. 
3. Drive slowly until  the trailer  is clear of the chocks. 
4. Stop  and have someone  pick up and  store  the chocks. 
Maintenance  When  Trailer  Towing 
Your  vehicle  will  need  service more often  when you’re 
pulling  a trailer.  See the Maintenance Schedule  for more 
on  this.  Things that are especially important in  trailer 
operation  are automatic transmission  fluid (don’t 
overfill),  engine oil, axle  lubricant,  belt, cooling system 
and  brake adjustment. Each  of these  is covered  in  this 
manual, and  the Index  will help  you 
find them  quickly. 
If  you’re trailering,  it’s a 
good idea  to  review  these 
sections before  you start  your trip. 
Check periodically  to see that  all hitch  nuts  and  bolts 
are  tight.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise 
This vehicle has  a  clutched  engine  cooling  fan. When 
the clutch is  engaged,  the fan  spins  faster  to  provide 
more  air 
to cool the  engine. In most everyday driving 
conditions,  the clutch is  not fully engaged.  This 
improves 
fuel economy and reduces  fan noise. Under 
heavy vehicle loading,  trailer towing and/or  high outside 
temperatures, the 
fan speed increases  when the clutch 
engages. 
So you may  hear an increase in fan noise.  This 
is normal and should  not be mistaken as  the 
transmission slipping  or making  extra shifts.  It is merely 
the cooling system  functioning properly. The  fan will 
slow down when additional  cooling 
is not required and 
the  clutch disengages. 
You may  also hear this fan noise when you start the 
engine.  It will  go away  as the  fan  clutch disengages. 
If a Tire  Goes Flat 
It’s unusual  for  a  tire to “blow out” while you’re  driving, 
especially  if 
you maintain your tires properly.  If air  goes 
out 
of a  tire,  it’s much more likely to leak out slowly. 
But  if you  should  ever have  a  “blowout,”  here are  a  few 
tips  about  what to  expect and what 
to do: 
If  a  front  tire fails, the 
flat tire will  create  a drag that 
pulls 
the vehicle toward that  side. Take your foot off the 
accelerator pedal and  grip the steering wheel firmly. 
Steer 
to maintain lane position, and then gently brake  to 
a  stop  well 
out of the traffic lane. 
A rear blowout, particularly on a  curve,  acts much like  a 
skid and  may require the same correction you’d  use  in a 
skid. 
In any rear blowout, remove your  foot from  the 
accelerator pedal. Get the vehicle under control  by 
steering 
the way  you  want  the  vehicle to go. It may  be 
very  bumpy and  noisy, but 
you can still steer. Gently 
brake  to  a  stop 
-- well  off  the road if possible. 
If  a tire goes  flat, 
the next part shows  how to use  your 
jacking  equipment  to change  a  flat tire safely.
