Limp Home Mode - Mahindra THAR CRDe 2015 Owner's Manual

7. Remove the jumper cables once the vehicle starts. Do this in the reverse of
the order in which they were attached, and don't let any of the cables or
clamps touch each other (or dangle into the engine compartment)
• Disconnect the black clamp from the grounded metal on the dead vehicle
• Disconnect the black clamp from the negative (-) terminal of the good
battery
• Disconnect the red clamp from the positive (+) terminal of the good battery
• Disconnect the red clamp from the positive (+) terminal of the dead battery
Replace any positive (+) red post protective covers if applicable (You have had
to remove or open these in the beginning) These covers help prevent
accidental short circuiting of the battery
8. Keep the recently-disabled vehicle's engine running. Run the vehicle above idle
(slightly revved up with your foot on the accelerator). This should give the
battery enough charge to start the vehicle again. If it does not, you probably
have a dead battery or a dying alternator
Improper jump starting procedures can result in battery explosion and acid
burn hazard.
Loosely connected battery cables could damage the electronic control units.
To disconnect battery terminals wait for at least 2 minutes to allow discharge
of high voltage or it could lead to personal injury.
While disconnecting, always disconnect the -VE terminal first and while
connecting, always connect the -VE terminal last.

Towing a vehicle to start could be dangerous. The vehicle being towed could
surge forward when the engine starts, causing the tow vehicles to collide,
injuring the occupants.
Modern vehicles with electronic management systems should not be jump
started without 'protected' jump starter leads. It is necessary to refer to the
owner's handbook for jump starting procedures for such vehicles.

12.5 Limp Home Mode

Limp home mode is an emergency situation declared by the EMS (Engine
Management System) due to failure of one/more critical sensors/actuators. In this
mode, the EMS (Engine Management System) will revert back to basic minimum
requirement (fuel quantity / injection timings) to aid the driver to bring the vehicle
back to the nearest workshop. Needless to say the drivability & fuel consumption will
be greatly affected.
If vehicle acceleration worsens or if there is a drop in vehicle performance, there
might be a malfunction in the engine management system which triggers/activates
the Limp Home Mode. This condition is accompanied by the check engine lamp
illuminating in the instrument cluster. In this mode, the vehicle speed is limited and
the accelerator pedal may not function normally. It is recommended you contact an
Authorized Mahindra Dealer immediately for assistance.
