Listed are four situations you may experience with your  f~~el gage: 
At the gas station. the fuel pump shuts  off before  the gage reads  full. 
It lakes a little more or less  fuel  to fill up  than  the  fuel gage indicated. 
For  example,  the gage  may have  indicated  the  tank  was  half 
full, but it 
actually took a little more  or less  than  half  the tank's  capacity to fill the 
, tank. 
The  gage  moves a little when  you turn a corner or speed  up. 
The  gage  doesn't go back  to  empty when  you turn off the ignition. 
None  of these indicate 
a problem with the  fuel  gage. 
For information on how to fill your fuel tank,  see "Fuel - Filling  Your 
Tank" 
in the Index. 
For your  fuel tank  capacity,  see "Fuel  -Tank  Capacity" in the Index. 
Engine  Coolant  Temperature  Gage 
This  gage  shows  the engine  coolant  temperature. Most of  the time. the gage 
pointer 
will show your coolant  temperature  at 2 10°F (99"C), or  less. But, if 
you  are pulling a heavy  load or driving LIP hills, your coolant temperature 
may  rise and 
fall near  the  red  260°F ( 128°C) mark. This is normal. If the 
gage  pointer  moves to the  red  260°F 
(128°C) mark, your engine  is too hot! 
It means that your engine coolant  has overheated. You should pull off the 
road, 
stop your vehicle.  and  turn off the engine as soon as possible. 
Hot Coolant Can Burn  You  Badly! 
In "Problems  on  the Road," this manual  shows what to do. See "Engine 
Overheating" 
in thc Index.
