If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, you can push down the
accelerator until the engine speed is about twice as fast
as normal idle speed for at least three minutes while
you are parked. If you still have the warning, turn off the
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.Cooling System
When you decide it is safe to lift the hood, here is what

Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch the
glass and/or cause damage to the rear window
defogger. When cleaning the glass on your vehicle,
use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space. Before
using cleaners, read and adhere to all safety instructions
on the label. While cleaning your vehicle’s interior,
maintain adequate ventilation by opening your vehicle’s
doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your dealer/retailer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your dealer/retailer to remove
odors from your vehicle’s upholstery.
Do not clean your vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to your vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
your interior and does not improve the effectiveness
of soil removal.
Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use only
mild, neutral-pH soaps.
Too much cleaner that saturates the upholstery.
Organic solvents such as naptha, alcohol, etc. that
can damage your vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on  oor carpet and carpeted  oor mats. For any soil,
always try to remove it  rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
