Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message STOP ENGINE
ENGINE OVERHEATING is displayed, an overheat protection mode
which alternates firing groups
of four cylinders helps prevent engine
damage. This operating mode allows your vehicle
to be driven to a safe
place in an emergency; you may drive
up to 50 miles (80 km). Towing a
trailer
in the overheat protection mode should be avoided.

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.
Stop after high speed driving.
Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign
of steam, try this for a minute
or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting 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

minutes while you’re parked, to see if the warning stops. But then, if you
still have the warning,
turn ofithe engine and get everyone out of the vehicle
until it cools down. Also see “Overheated Engine Protection Operating
Mode” listed previously

pressure left.

IFA 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, 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.
