Winter  Driving 
Here  are  some  tips  for winter driving: 
0 Have  your  vehicle in good shape  for  winter. Be sure  your  engine 
coolant  mix is correct. 
You may  want to put winter  emergency  supplies  in your  vehicle. 
Include  an ice  scraper,  a  small brush or broom,  a  supply  of windshield 
washer  fluid,  a  rag,  some  winter outer  clothing,  a  small  shovel, 
a flashlight, 
a  red  cloth,  and a  couple  of reflective  warning triangles.  And, if you  will  be 
driving  under  severe  conditions,  include  a  small  bag 
of sand,  a  piece of old 
carpet  or a  couple 
of burlap bags  to help  provide  traction. Be sure  you 
properly  secure 
these items  in your vehicle. 
Driving on Snow  or Ice 
Most of the  time,  those  places where  your  tires meet  the road probably  have 
good traction. 
However,  if there  is snow 
or ice  between  your  tires and the  road,  you can 
have  a  very  slippery  situation. You’ll have  a  lot  less  traction 
or “grip” and 
will  need  to  be  very careful.

When towing at high  altitude on steep  uphill grades,  consider  the following: 
Engine  coolant  will boil at a lower temperature than  at normal altitudes.  If 
you turn your engine off immediately  after towing at high altitude on steep 
uphill grades, your vehicle 
may show signs similar to engine  overheating. 
To avoid this, let the  engine  run while parked  (preferably  on  level ground) 
with the automatic transmission 
in PARK  (Pj  (or  the manual transmission 
out 
of gear  and the parking brake  applied) for a few minutes before turning 
the  engine  off. 
If you do  get  the overheat warning,  see “Engine 
Overheating” 
in the Index. 
Parking on Hills 
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. 
2. 
3. 
4. 
5. 
6. 
Apply your regular brakes,  but don’t  shift into PARK (P) yet, or in gear 
for  a  manual transmission. 
Have  someone  place chocks  under the trailer wheels. 
When the  wheel chocks  are 
in place, release the regular brakes until the 
chocks  absorb  the load. 
Re-apply  the regular brakes.  Then apply your parking brake, and then 
shift 
to PARK  (P),  or  REVERSE (Rj for  a manual transmission. 
If  you  have 
a four-wheel-drive  vehicle, be sure  the transfer  case is in a 
drive  gear-not  in  NEUTRAL 
(N). 
Release the regular brakes. 
A CAUTION: 
It can  be dangerous  to  get out of your  vehicle  if the shift  lever  is 
not  fully  in 
PARK  (P) with the parking  brake  firmly set.  Your 
vehicle  can rofl. 
If you  have  Ieft the engine  running, the  vehicle can move 
suddenly.  You or others  could  be  injured. 
To be sure  your  vehicle 
won’t  move,  even  when  you’re  on  fairly level ground,  use the 
steps  that follow. 
If you have  four-wheel  drive and your transfer  case is in 
NEUTRAL  (N), your vehicle  will  be  free to roll,  even  if your 
shift lever  is  in 
PARK (P). So, be sure  the  transfer  case is in a 
drive  gear 
- not in NEUTRAL  (N).

Problems on  the Road 
Section 
Here you’ll find what to do about  some problems  that can  occur on the road. 
Hazard  Warning  Flashers

top  of  the  steering 
column  all  the  way 
down  to make 
your 
front  and rear  turn 
signals flash  on and 
off.

and even if the key  isn’t in. 
To turn off the flashers,  push the button until the first click and release. 
When the hazard warning  flashers are on,  your turn signals won’t work. 
Other  Warning  Devices 
If you  carry reflective triangles,  you can use them  to  warn  others. Set one  up 
at  the  side  of the  road  about 
300 feet (100 m) behind your vehicle. 
Jump Starting 
If your  battery  (or batteries) has  run down,  you may want to  use another 
vehicle  and some  jumper  cables 
to start your vehicle.  But please follow the 
steps below to  do it safely. 
A CAUTION: 
Batteries  can  hurt  you.  They  can  be  dangerous  because: 
They  contain acid that  can burn you. 
They  contain  gas  that  can  explode or ignite. 
0 They  contain  enough  electricity  to  burn you. 
If you  don’t  follow  these  steps exactly,  some  or  all  of  these things 
can hurt  you.

vehicle. They  can  provide the right equipment  and know how to tow 
it 
without  damage. 
If  your  vehicle has been changed  since 
it was  factory-new.  by  adding such 
things  like  fog  lamps,  aero  skirting, 
or special tires and  wheels, these things 
could  be damaged  during  towing. 
Before  you do anything, 
turn on the hazard  warning  flashers. 
When you  call, tell the towing  service: 
0 That  your  vehicle  has  rear-wheel drive,  or that it has the four-wheel 
drive  option. 
The  make,  model, and year  of your vehicle. 
0 Whether you can  move the shift lever for the transmission  and transfer 
case, 
if you  have  one. 
If there was  an accident.  what was damaged. 
A CAUTION: 
To help  avoid  injury  to you  or others: 
Never  let  passengers ride  in a vehicle  that is  being  towed. 
0 Never  tow  faster  than  safe or posted  speeds. 
0 Never  tow  with  damaged parts not fuIly  secured. 
0 Never  get  under your vehicle  after  it has been  lifted  by the 
tow  truck. 
0 Always  use  separate safety chains on  each  side  when  towing  a 
vehicle. 
0 For  pickups  (except cab chassis  models),  use  T-hooks  on front 
. of vehicle,  J-hooks  on rear. 
For  cab  chassis  models,  use  J-hooks  on  front  and rear of

If No Steam Is Coming From Your Engine 
If you get the  overheat  warning  but see  or  hear no  steam, the problem  may 
not  be  too  serious.  Sometimes  the engine  can get  a  little too hot  when  you: 
0 Climb  a  long  hill on a hot day. 
0 Stop  after  high speed  driving. 
0 Idle for  long  periods in traffic. 
Tow a trailer.  See “Driving  on Grades’’ in the  Index. 
If 
you get  the  overheat  warning with no sign  of steam,  try this  for  a  minute 
or 
so: 
1. If  you  have an air  conditioner, turn it  off. 
2. Turn on your  heater to full hot at the  highest  fan speed and open the 
window  as necessary. 
3. If you’re  in a traffic  jam, shift to  NEUTRAL  (N);  otherwise,  shift to the 
highest  gear  while  driving 
- AUTOMATIC  OVERDRIVE (@) or 
DRIVE 
(3) for  automatic  transmissions. 
If  you  no  longer  have  the overheat  warning,  you can  drive.  Just  to  be  safe, 
drive  slower  for  about  ten minutes.  If the warning doesn’t  come back on, 
you  can drive  normally. 
If 
the warning  continues,  pull  over, stop, and park your vehicle right away. 
If there’s still no sign of steam,  push the  accelerator  until the engine speed is 
about  twice  as  fast  as  normal idle speed.  Bring the engine  speed back  to 
normal  idle  speed  after  two  or three minutes.  Now  see 
if the warning  stops. 
But  then,  if 
you still  have  the  warning, turn  ofSthe engine and get everyone 
out of the vehicle until it cools  down. 
You may decide not to lift the  hood but to  get  service  help right  away.

When  the coolant in the coolant  recovery  tank is at or above the COLD 
mark. start your vehicle. 
If the overheat  warning continues,  there’s one more thing  you can try. You 
can add 
the proper  coolant mix directly  to  the radiator, but  be  sure the 
cooling  system 
is cool  before  you do it. 
A CAUTION: 
Steam  and  scalding  liquids  from a hot  cooling  system  can  blow 
out  and  burn  you badly.  They  are  under  pressure,  and  if you 
turn  the  radiator  pressure  cap 
- even a little - they  can  come 
out 
at high  speed.  Never  turn  the  cap  when  the  cooling  system, 
including  the  radiator  pressure  cap,  is  hot.  Wait  for  the  cool\
ing 
system  and  radiator  pressure  cap  to  cool if you  ever  have  to  turn 
the  pressure  cap.

A CAUTION: 
Steam and scalding  liquids from a hot cooling  system  can  blow 
out  and  burn  you  badly.  They are under  pressure, and 
if you 
turn  the coolant surge  tank pressure  cap 
- even a little - they 
can  come  out at high  speed.  Never  turn the cap  when the cooling 
system,  including  the coolant surge  tank pressure cap, 
is hot. 
’ Wait  for the  cooling  system  and coolant surge  tank pressure cap 
to  cool 
if you  ever  have  to turn  the pressure cap. 
A CAUTION: 
Adding  only plain water to your  cooling  system can be 
dangerous. Plain  water, or some  other  liquid like  alcohol, can 
boil  before  the  proper coolant mix 
will. Your  vehicle’s  coolant 
warning  system  is  set for  the  proper  coolant mix. With plain 
water 
or the wrong  mix, your engine  could get too  hot  but  you 
wouldn’t  get  the overheat warning.  Your engine could catch  fire 
and  you or others  could be burned.  Use 
a 50/50 mix of clean 
water  and a proper  antifreeze.
